【中文标题】如何在 Android 设备中检测来电?【英文标题】:How to detect incoming calls, in an Android device? 【发布时间】:2013-03-11 22:20:05 【问题描述】:

我正在尝试制作一个应用,例如,当电话打到我想检测号码时。以下是我尝试过的,但它没有检测到来电。

我想在后台运行我的MainActivity,我该怎么做?

我已在manifest 文件中授予权限。

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

我还应该在清单中提供什么吗?

public class MainActivity extends Activity 
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test_layout);
   

   public class myPhoneStateChangeListener extends PhoneStateListener 
       @Override
       public void onCallStateChanged(int state, String incomingNumber) 
           super.onCallStateChanged(state, incomingNumber);
           if (state == TelephonyManager.CALL_STATE_RINGING) 
               String phoneNumber =   incomingNumber;
           
       
   

【问题讨论】:

我们应该为android P做什么 【参考方案1】:

这是我用来执行此操作的:

清单:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

<!--This part is inside the application-->
    <receiver android:name=".CallReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

我的基础可重用呼叫检测器

package com.gabesechan.android.reusable.receivers;

import java.util.Date;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;

public abstract class PhonecallReceiver extends BroadcastReceiver 

    //The receiver will be recreated whenever android feels like it.  We need a static variable to remember data between instantiations

    private static int lastState = TelephonyManager.CALL_STATE_IDLE;
    private static Date callStartTime;
    private static boolean isIncoming;
    private static String savedNumber;  //because the passed incoming is only valid in ringing


    @Override
    public void onReceive(Context context, Intent intent) 

        //We listen to two intents.  The new outgoing call only tells us of an outgoing call.  We use it to get the number.
        if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) 
            savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");
        
        else
            String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
            String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
            int state = 0;
            if(stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE))
                state = TelephonyManager.CALL_STATE_IDLE;
            
            else if(stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
                state = TelephonyManager.CALL_STATE_OFFHOOK;
            
            else if(stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING))
                state = TelephonyManager.CALL_STATE_RINGING;
            


            onCallStateChanged(context, state, number);
        
    

    //Derived classes should override these to respond to specific events of interest
    protected abstract void onIncomingCallReceived(Context ctx, String number, Date start);
    protected abstract void onIncomingCallAnswered(Context ctx, String number, Date start);
    protected abstract void onIncomingCallEnded(Context ctx, String number, Date start, Date end);

    protected abstract void onOutgoingCallStarted(Context ctx, String number, Date start);      
    protected abstract void onOutgoingCallEnded(Context ctx, String number, Date start, Date end);

    protected abstract void onMissedCall(Context ctx, String number, Date start);

    //Deals with actual events

    //Incoming call-  goes from IDLE to RINGING when it rings, to OFFHOOK when it's answered, to IDLE when its hung up
    //Outgoing call-  goes from IDLE to OFFHOOK when it dials out, to IDLE when hung up
    public void onCallStateChanged(Context context, int state, String number) 
        if(lastState == state)
            //No change, debounce extras
            return;
        
        switch (state) 
            case TelephonyManager.CALL_STATE_RINGING:
                isIncoming = true;
                callStartTime = new Date();
                savedNumber = number;
                onIncomingCallReceived(context, number, callStartTime);
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                //Transition of ringing->offhook are pickups of incoming calls.  Nothing done on them
                if(lastState != TelephonyManager.CALL_STATE_RINGING)
                    isIncoming = false;
                    callStartTime = new Date();
                    onOutgoingCallStarted(context, savedNumber, callStartTime);                     
                
                else
                
                    isIncoming = true;
                    callStartTime = new Date();
                    onIncomingCallAnswered(context, savedNumber, callStartTime); 
                

                break;
            case TelephonyManager.CALL_STATE_IDLE:
                //Went to idle-  this is the end of a call.  What type depends on previous state(s)
                if(lastState == TelephonyManager.CALL_STATE_RINGING)
                    //Ring but no pickup-  a miss
                    onMissedCall(context, savedNumber, callStartTime);
                
                else if(isIncoming)
                    onIncomingCallEnded(context, savedNumber, callStartTime, new Date());                       
                
                else
                    onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());                                               
                
                break;
        
        lastState = state;
    

然后要使用它,只需从中派生一个类并实现一些简单的功能,无论您关心哪种调用类型:

public class CallReceiver extends PhonecallReceiver 

    @Override
    protected void onIncomingCallReceived(Context ctx, String number, Date start)
    
        //
    

    @Override
    protected void onIncomingCallAnswered(Context ctx, String number, Date start)
    
        //
    

    @Override
    protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end)
    
        //
    

    @Override
    protected void onOutgoingCallStarted(Context ctx, String number, Date start)
    
        //
     

    @Override 
    protected void onOutgoingCallEnded(Context ctx, String number, Date start, Date end)
    
        //
    

    @Override
    protected void onMissedCall(Context ctx, String number, Date start)
    
        //
    


此外,您还可以看到我写的关于为什么代码与我的blog 上的代码类似的文章。要点链接:https://gist.github.com/ftvs/e61ccb039f511eb288ee

编辑:更新为更简单的代码,因为我已经重新编写了该类以供自己使用

【讨论】:

此代码不显示任何内容。它的作用是在拨出电话开始/结束时呼叫您,并向您传递号码、开始时间和结束时间。实际上展示它是你的工作,因为我不知道你想怎么做。 @GabeSechan:太棒了!你能指导我处理呼叫等待的情况吗? 只是补充一下,当应用程序不在前台或后台时它不起作用,直到我在接收器中添加了这个:“android:enabled="true" 静态变量将一直存在,直到应用程序被踢出内存(这可能会很长一段时间,具体取决于服务是否正在运行和一般手机内存条件)。但是,是的,它们可能会丢失。您可以通过共享首选项将其写入磁盘,但这也可能导致您得到错误的结果 - 它会阻止您在某些情况下正确清除数据,例如在手机重启时。对于我的用例,罕见的空数据和丢失数据比不正确的数据要好。您可以根据自己的需要随意调整。 @GabeSechan :其中似乎有一个错误。 lastState 不应初始化为 CALL_STATE_IDLE。当我的应用程序在当前状态为RINGING 时被杀死时,我错过了几个电话。因为当它在通话结束时再次变为IDLE 时,静态变量会重新初始化为CALL_STATE_IDLE 并且它什么都不做会去抖动。所以我们失去了对lastState的引用。【参考方案2】:
private MyPhoneStateListener phoneStateListener = new MyPhoneStateListener();

注册

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

注销

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);

【讨论】:

我应该在 mainactivity 哪里使用它? 把它放在你正在监听变化的类中。通常注册在 oncreate 中完成,在 ondestroy 中取消注册。在类中全局声明对象 此选项不需要权限。 虽然 Gabe 的解决方案更适合更具侵入性的功能,即 Viber 类应用程序,但对于那些需要简单地对用户拨打电话的操作做出反应的人来说,这是最佳解决方案。在这种情况下请求运行时权限很可能是矫枉过正,可能不会被用户接受。 我想做点什么,电话来了,这段代码怎么办?【参考方案3】:

使用 Android P - API 级别 28: You need to get READ_CALL_LOG permission

限制访问通话记录

Android P 将CALL_LOGREAD_CALL_LOGWRITE_CALL_LOGPROCESS_OUTGOING_CALLS 权限从PHONE 权限组移至新的CALL_LOG 权限组。该组可让用户更好地控制和查看需要访问电话敏感信息(例如读取电话记录和识别电话号码)的应用。

要从 PHONE_STATE 意图操作中读取数字,您需要READ_CALL_LOG 权限和READ_PHONE_STATE 权限。 要从onCallStateChanged() 读取数字,您现在只需要READ_CALL_LOG 权限。您不再需要READ_PHONE_STATE 权限。

【讨论】:

对于那些只在AndroidManifest.xml中添加READ_CALL_LOG的人,重点在MainActivity中添加权限请求。 我正在研究一些替代方法。我们可以从通知监听器中获取手机号码。但是存在一个问题,即来电不作为通知处理的某些设备。所以我没有得到手机号码。 如果我在我的应用程序中使用READ_CALL_LOG 权限,我应该在 Google Play Console 上填写声明。如果我使用READ_CALL_LOG 权限从电话簿中搜索姓名,我需要从列表中选择什么?【参考方案4】:

更新:Gabe Sechan 发布的非常棒的代码不再有效,除非您明确要求用户授予必要的权限。下面是一些代码,您可以在主 Activity 中放置这些代码来请求这些权限:

    if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) 
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]Manifest.permission.READ_PHONE_STATE,
                MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
    

    if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
            != PackageManager.PERMISSION_GRANTED) 
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]Manifest.permission.PROCESS_OUTGOING_CALLS,
                MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
    

另外:正如某人在Gabe's post 下方的评论中提到的那样,您必须向接收器添加一点 sn-p 代码 android:enabled="true,以便在应用程序当前未在前景:

    <!--This part is inside the application-->
    <receiver android:name=".CallReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

【讨论】:

如果应用程序没有任何Activity,只有广播接收器和服务怎么办。那么我们在哪里编写这段代码来获得用户的权限,因为在获得此权限之前不会调用广播接收器。 你至少需要一个 MainActivity,即使它只打开一次。以我的呼叫拦截应用 RoboStop 为例:当用户第一次下载应用,然后点击应用图标启动应用时,系统会提示他们授予我的应用必要的权限。该应用程序还具有启用/禁用呼叫阻止的按钮,但用户无需再次启动应用程序/活动,呼叫阻止将在后台进行,而无需用户再次启动应用程序/活动。 那些难以实现的人,请遵循本教程studytutorial.in/…【参考方案5】:

只是为了更新 Gabe Sechan 的答案。如果您的清单要求获得 READ_CALL_LOG 和 READ_PHONE_STATE 的权限,onReceive 将调用 TWICE。其中一个有 EXTRA_INCOMING_NUMBER,另一个没有。你必须测试哪个有它,它可以以任何顺序出现。

【参考方案6】:

这可能会对您有所帮助并添加要求权限

public class PhoneListener extends PhoneStateListener

    private Context context;
    public static String getincomno;

    public PhoneListener(Context c) 
        Log.i("CallRecorder", "PhoneListener constructor");
        context = c;
    

    public void onCallStateChanged (int state, String incomingNumber)
    

        if(!TextUtils.isEmpty(incomingNumber))
        // here for Outgoing number make null to get incoming number
        CallBroadcastReceiver.numberToCall = null;
        getincomno = incomingNumber;
        

        switch (state) 
        case TelephonyManager.CALL_STATE_IDLE:

            break;
        case TelephonyManager.CALL_STATE_RINGING:
            Log.d("CallRecorder", "CALL_STATE_RINGING");
            break;
        case TelephonyManager.CALL_STATE_OFFHOOK:

            break;
        
    

【讨论】:

这似乎没问题。但是我如何从活动中使用它?请告诉我详情【参考方案7】:

我修复了Gabe Sechan answer,我使用了以下代码并且它工作正常。 我注意到当接收者意图具有“incoming_number”键时,我可以获得电话号码。所以我过滤了传入意图并使用 EXTRA_INCOMING_NUMBEREXTRA_PHONE_NUMBER 来获取电话号码。

public class ChangeCallStateListener extends BroadcastReceiver 

    private static String lastState = TelephonyManager.EXTRA_STATE_IDLE;
    private static Date callStartTime;
    private static boolean isIncoming;
    private static String savedNumber;  //because the passed incoming is only valid in ringing

    @Override
    public void onReceive(Context context, Intent intent) 
        Log.d("CallObserver", "CallReceiver is starting ....");

        List<String> keyList = new ArrayList<>();
        Bundle bundle = intent.getExtras();
        if (bundle != null) 
            keyList = new ArrayList<>(bundle.keySet());
            Log.e("CallObserver", "keys : " + keyList);
        

        if (keyList.contains("incoming_number")) 
            String phoneState = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
            String phoneIncomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
            String phoneOutgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

            String phoneNumber = phoneOutgoingNumber != null ? phoneOutgoingNumber : (phoneIncomingNumber != null ? phoneIncomingNumber : "");

            if (phoneState != null && phoneNumber != null) 
                if (lastState.equals(phoneState)) 
                    //No change, debounce extras
                    return;
                
                Log.e("CallObserver", "phoneState = " + phoneState);
                if (TelephonyManager.EXTRA_STATE_RINGING.equals(phoneState)) 
                    isIncoming = true;
                    callStartTime = new Date();
                    //

                    if (phoneNumber != null) 
                        savedNumber = phoneNumber;
                    


                    onIncomingCallStarted(context, savedNumber, callStartTime);
                 else if (TelephonyManager.EXTRA_STATE_IDLE.equals(phoneState)) 

                    if (lastState.equals(TelephonyManager.EXTRA_STATE_RINGING)) 
                        //
                        lastState = TelephonyManager.EXTRA_STATE_IDLE;
                        onMissedCall(context, savedNumber, callStartTime);
                     else 
                        if (isIncoming) 
                            //
                            lastState = TelephonyManager.EXTRA_STATE_IDLE;
                            onIncomingCallEnded(context, savedNumber, callStartTime, new Date());

                            Log.d("CallObserver", "onOutgoingCallEnded called !! : ");
                            onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());

    protected void onIncomingCallEnded(Context context, String number, Date start, Date end) 
    

    protected void onOutgoingCallEnded(Context context , String number, Date start, Date end) 
    

    protected void onMissedCall(Context context, String number, Date start) 
    


别忘了获得运行时权限。

  <uses-permission android:name="android.permission.READ_PHONE_STATE" />

【讨论】:

您是如何绕过 READ_PRIVILEGED_PHONE_STATE 权限的?我在我的日志中看到了这个:requires android.permission.READ_PRIVILEGED_PHONE_STATE due to sender android (uid 1000) 现在记不太清楚了,试试READ_CALL_LOG权限【参考方案8】:

这是一个简单的方法,可以避免使用PhonestateListener和其他并发症。 所以在这里我们接收到来自 android 的 3 个事件,例如 RINGINGOFFHOOKIDLE。为了获得所有可能的调用状态,我们需要定义自己的状态,如RINGINGOFFHOOKIDLEFIRST_CALL_RINGINGSECOND_CALL_RINGING。 它可以处理电话中的每个状态。 请以我们正在接收来自 android 的事件的方式思考,我们将定义我们的待命状态。查看代码。

public class CallListening  extends BroadcastReceiver

    private String current_state,previus_state,event;

    private SharedPreferences.Editor spEditor,spEditor1;
    public void onReceive(Context context, Intent intent) 
        //Log.d("intent_log", "Intent" + intent);
        dialog=true;
        this.context = context;
        event = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        incoming_number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        Log.d(TAG, "The received event : "+event+", incoming_number : " + incoming_number);
        previus_state = getCallState(context);
        current_state = "IDLE";
        if(incoming_number!=null)
            updateIncomingNumber(incoming_number,context);
        else 
            incoming_number=getIncomingNumber(context);
        
        switch (event) 
            case "RINGING":
                Log.d(TAG, "State : Ringing, incoming_number : " + incoming_number);
            if((previus_state.equals("IDLE")) || (previus_state.equals("FIRST_CALL_RINGING")))
                    current_state ="FIRST_CALL_RINGING";
                
                if((previus_state.equals("OFFHOOK"))||(previus_state.equals("SECOND_CALL_RINGING")))
                    current_state = "SECOND_CALL_RINGING";
                

                break;
            case "OFFHOOK":
                Log.d(TAG, "State : offhook, incoming_number : " + incoming_number);
                if((previus_state.equals("IDLE")) ||(previus_state.equals("FIRST_CALL_RINGING")) || previus_state.equals("OFFHOOK"))
                    current_state = "OFFHOOK";
                
                if(previus_state.equals("SECOND_CALL_RINGING"))
                    current_state ="OFFHOOK";
                    startDialog(context);

@Gabe Sechan,感谢您的代码。除了onOutgoingCallEnded(),它工作正常。它永远不会被执行。测试手机是三星 S5 & Trendy。我认为有2个错误。

1:缺少一对括号。

case TelephonyManager.CALL_STATE_IDLE: 
    // Went to idle-  this is the end of a call.  What type depends on previous state(s)
    if (lastState == TelephonyManager.CALL_STATE_RINGING) 
        // Ring but no pickup-  a miss
        onMissedCall(context, savedNumber, callStartTime);
     else 
        // this one is missing
        if(isIncoming)
            onIncomingCallEnded(context, savedNumber, callStartTime, new Date());                       
         else 
            onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());                                               
        
    
    // this one is missing
    break;

2:lastState 不会被 state 更新,如果它位于函数的末尾。它应该被替换为该函数的第一行

public void onCallStateChanged(Context context, int state, String number) 
    int lastStateTemp = lastState;
    lastState = state;
    // todo replace all the "lastState" by lastStateTemp from here.
    if (lastStateTemp  == state) 
        //No change, debounce extras
        return;
    
    //....

另外,我已按照您的建议将 lastStatesavedNumber 放入共享偏好中。

刚刚使用上述更改对其进行了测试。至少在我的手机上修复了错误。

    txtcall = (TextView) findViewById(R.id.call);

    StringBuffer sb = new StringBuffer();
    Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI, null,
            null, null, null);
    int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
    int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
    int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
    int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
    sb.append("Call Details :");
    while (managedCursor.moveToNext()) 
        String phNumber = managedCursor.getString(number);
        String callType = managedCursor.getString(type);
        String callDate = managedCursor.getString(date);
        Date callDayTime = new Date(Long.valueOf(callDate));
        String callDuration = managedCursor.getString(duration);

            break;

        case CallLog.Calls.INCOMING_TYPE:
            dir = "INCOMING";
            break;

        case CallLog.Calls.MISSED_TYPE:
            dir = "MISSED";

并在您的清单请求中获得以下权限:

<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.READ_LOGS"/>

【讨论】:

READ_LOGS 这样做是为了让您的应用被禁止进入 Play 商店【参考方案11】:

您需要一个用于ACTION_PHONE_STATE_CHANGED 的广播接收器,只要电话状态从空闲、响铃、摘机更改为之前的值和您可以检测到这是传入/传出呼叫的新值,这将调用您的接收。

所需的权限是:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

但如果您还想在该广播中接收 EXTRA_INCOMING_NUMBER,则需要另一个权限:“android.permission.READ_CALL_LOG”

代码如下:

val receiver: BroadcastReceiver = object : BroadcastReceiver() 
    override fun onReceive(context: Context, intent: Intent) 
        Log.d(TAG, "onReceive")
    


override fun onResume() 
    val filter = IntentFilter()
    filter.addAction("android.intent.action.PHONE_STATE")
    registerReceiver(receiver, filter)
    super.onResume()


override fun onPause() 
    unregisterReceiver(receiver)
    super.onPause()

在接收器类中,我们可以通过读取意图来获取当前状态,如下所示:

intent.extras["state"]

额外的结果可能是:

RINGING -> 如果您的手机正在响铃

OFFHOOK -> 如果您正在与某人交谈(传入或传出 打电话)

IDLE -> 如果通话结束(来电或去电)

使用 PHONE_STATE 广播,我们不需要使用 PROCESS_OUTGOING_CALLS 权限或已弃用的 NEW_OUTGOING_CALL 操作。

【讨论】:

【参考方案12】:

参考Gabe Sechan的回答。如前所述,在拨出呼叫的情况下,我们有以下状态更改:IDLE -> OFFHOOK -> IDLE。在 Gabe 的原始答案中,savedNumber 仅在电话状态变为 RINGING 时才设置,这对于拨出电话来说不是真的。当电话状态变为 OFFHOOK 时,还设置 savedNumber 的一个小修复:

case TelephonyManager.CALL_STATE_OFFHOOK:
    if(lastState != TelephonyManager.CALL_STATE_RINGING)
        //IDLE to OFFHOOK for example.
        isIncoming = false;
        callStartTime = new Date();
        savedNumber = number;
        onOutgoingCallStarted(context, savedNumber, callStartTime);
    
...

此修复允许将拨打的号码传递给拨出呼叫方法,就像传入号码传递给来电或未接来电方法一样。
