Android实现拨号功能

Posted 2023-03-25

public class TinyDialer extends Activity

/** Called when the activity is first created. */
private Button button;
private EditText phonenumber;
@Override
public void onCreate(Bundle savedInstanceState)

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

button = (Button)findViewById(R.id.button_id);
phonenumber = (EditText)findViewById(R.id.phonenumber_id);
button.setOnClickListener(new OnClickListener()
public void onClick(View v)
String call = phonenumber.getText().toString();
if(PhoneNumberUtils.isGlobalPhoneNumber(call))
Intent i = new Intent();

i.setAction(Intent.ACTION_DIAL);
i.setData(Uri.parse(call));
startActivity(i);

else
Toast.makeText(TinyDialer.this, R.string.correct_number, Toast.LENGTH_LONG).show();


);
这个程序是实现拨号的，程序本身没有错误，但是不能进行拨号功能，不知道还有什么地方有错误，帮忙帮我找出来下，谢谢~~~
已将i.setAction(Intent.ACTION_DIAL);
改为 i.setAction(Intent.ACTION_CALL);
还是不能实现这个功能

请检查你这个activity的permission，有没有加上以下的设置。
在androidManifest.xml里面添加。

<uses-permission android:name="android.permission.BROADCAST_STICKY" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.CALL_PRIVILEGED" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

另外帮你贴下android自带拨号程序的核心部分，请自己参照下吧～～
public class OutgoingCallBroadcaster extends Activity

private static final String PERMISSION = android.Manifest.permission.PROCESS_OUTGOING_CALLS;
private static final String TAG = "OutgoingCallBroadcaster";
private static final boolean LOGV = true;//Config.LOGV;

public static final String EXTRA_ALREADY_CALLED = "android.phone.extra.ALREADY_CALLED";
public static final String EXTRA_ORIGINAL_URI = "android.phone.extra.ORIGINAL_URI";

private Phone mPhone;

@Override
protected void onCreate(Bundle icicle)
super.onCreate(icicle);

mPhone = PhoneApp.getInstance().phone;

Intent intent = getIntent();
if (LOGV) Log.v(TAG, "onCreate: Got intent " + intent + ".");

String action = intent.getAction();
String number = PhoneNumberUtils.getNumberFromIntent(intent, this);
if (number != null)
number = PhoneNumberUtils.stripSeparators(number);

final boolean emergencyNumber =
(number != null) && PhoneNumberUtils.isEmergencyNumber(number);

boolean callNow;

if (getClass().getName().equals(intent.getComponent().getClassName()))
// If we were launched directly from the OutgoingCallBroadcaster,
// not one of its more privileged aliases, then make sure that
// only the non-privileged actions are allowed.
if (!Intent.ACTION_CALL.equals(intent.getAction()))
Log.w(TAG, "Attempt to deliver non-CALL action; forcing to CALL");
intent.setAction(Intent.ACTION_CALL);



/* Change CALL_PRIVILEGED into CALL or CALL_EMERGENCY as needed. */
if (Intent.ACTION_CALL_PRIVILEGED.equals(action))
action = emergencyNumber
? Intent.ACTION_CALL_EMERGENCY
: Intent.ACTION_CALL;
intent.setAction(action);


if (Intent.ACTION_CALL.equals(action))
if (emergencyNumber)
finish();
return;

callNow = false;
else if (Intent.ACTION_CALL_EMERGENCY.equals(action))
if (!emergencyNumber)
finish();
return;

callNow = true;
else
finish();
return;


// Make sure the screen is turned on. This is probably the right
// thing to do, and more importantly it works around an issue in the
// activity manager where we will not launch activities consistently
// when the screen is off (since it is trying to keep them paused
// and has... issues).
//
// Also, this ensures the device stays awake while doing the following
// broadcast; technically we should be holding a wake lock here
// as well.
PhoneApp.getInstance().wakeUpScreen();

/* If number is null, we're probably trying to call a non-existent voicemail number or
* something else fishy. Whatever the problem, there's no number, so there's no point
* in allowing apps to modify the number. */
if (number == null || TextUtils.isEmpty(number)) callNow = true;

if (callNow)
intent.setClass(this, InCallScreen.class);
startActivity(intent);


Intent broadcastIntent = new Intent(Intent.ACTION_NEW_OUTGOING_CALL);
if (number != null) broadcastIntent.putExtra(Intent.EXTRA_PHONE_NUMBER, number);
broadcastIntent.putExtra(EXTRA_ALREADY_CALLED, callNow);
broadcastIntent.putExtra(EXTRA_ORIGINAL_URI, intent.getData().toString());
broadcastIntent.putExtra(EXTRA_INTENT_FROM_BT_HANDSFREE,
intent.getBooleanExtra(OutgoingCallBroadcaster.EXTRA_INTENT_FROM_BT_HANDSFREE, false));

if (LOGV) Log.v(TAG, "Broadcasting intent " + broadcastIntent + ".");
sendOrderedBroadcast(broadcastIntent, PERMISSION, null, null,
Activity.RESULT_OK, number, null);

finish();


参考技术A private OnClickListener myListener = new Button.OnClickListener()

@Override
public void onClick(View v)


//调用系统的拨号服务实现电话拨打功能
String phone_number = numberEt.getText().toString();

phone_number = phone_number.trim();//删除字符串首部和尾部的空格

if(phone_number != null && !phone_number.equals(""))


//调用系统的拨号服务实现电话拨打功能
//封装一个拨打电话的intent，并且将电话号码包装成一个Uri对象传入
Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+phone_number));
MyPhoneActivity.this.startActivity(intent);//内部类



;
最后在在AndroidManifest.xml里面添加

<uses-permission android:name="android.permission.CALL_PHONE"/> 参考技术B intent.setAction(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:" +call));
因为data的格式前缀必须有" tel："
=========================================================================
在AndroidManifest.xml中不需要加权限，
当intent.setAction(Intent.ACTION_CALL); 时，
才需要CALL_PHONE权限 参考技术C i.setAction(Intent.ACTION_DIAL);
改为 i.setAction(Intent.ACTION_CALL); 参考技术D 在setData方法中的参数改为：Uri.parse("tel:" + call) ，并加入CALL_PHONE权限

Android 拨号器的简单实现

功能实现：一个EditView 一个拨打按钮，输入号码跳转到拨号界面

界面布局：activity_call.xml

　　//线性垂直布局：一个EditView文本、一个Button按钮
 1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:orientation="vertical"
 6     android:paddingBottom="@dimen/activity_vertical_margin"
 7     android:paddingLeft="@dimen/activity_horizontal_margin"
 8     android:paddingRight="@dimen/activity_horizontal_margin"
 9     android:paddingTop="@dimen/activity_vertical_margin"
10     tools:context=".PhoneActivity" >
11 
12     <TextView
13         android:layout_width="wrap_content"
14         android:layout_height="wrap_content"
15         android:text="请输入电话" />
16 
17     <EditText
18         android:id="@+id/editText1"
19         android:layout_width="fill_parent"
20         android:layout_height="wrap_content"
21         android:inputType="phone" />
22 
23     <Button
24         android:id="@+id/callsumbit"
25         android:layout_width="wrap_content"
26         android:layout_height="wrap_content"
27         android:layout_gravity="center"
28         android:text="拨打电话" />
29 
30 </LinearLayout>

CallActivity的Create方法

 1 protected void onCreate(Bundle savedInstanceState) {
 2         super.onCreate(savedInstanceState);
 3         setContentView(R.layout.activity_call);
 4         Button btn = (Button) findViewById(R.id.callsumbit);
 5         btn.setOnClickListener(new OnClickListener() {
 6 
 7             @Override
 8             public void onClick(View v) {
 9                 EditText etNumber = (EditText) findViewById(R.id.editText1);
10 
11                 String number = etNumber.getText().toString();
12                 Intent intent = new Intent();
13                 intent.setAction(Intent.ACTION_CALL);
14                 intent.setData(Uri.parse("tel:" + number));
15                 startActivity(intent);
16             }
17         });
18     }

增加拨打电话的权限：AndroidManifest.xml

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
 3     package="com.ccec.callphone"
 4     android:versionCode="1"
 5     android:versionName="1.0" >
 6 
 7     <uses-sdk
 8         android:minSdkVersion="8"
 9         android:targetSdkVersion="18" />
10     <uses-permission android:name="android.permission.CALL_PHONE"/>
11 
12     <application
13         android:allowBackup="true"
14         android:icon="@drawable/ic_launcher"
15         android:label="@string/app_name"
16         android:theme="@style/AppTheme" >
17         <activity
18             android:name="com.ccec.callphone.CallActivity"
19             android:label="@string/app_name" >
20             <intent-filter>
21                 <action android:name="android.intent.action.MAIN" />
22 
23                 <category android:name="android.intent.category.LAUNCHER" />
24             </intent-filter>
25         </activity>
26     </application>
27 
28 </manifest>

至此可以实现拨号功能。
