【问题描述】：

我需要帮助！我真的对Java编程一无所知。我们正在尝试制作一个 SMS Reminder 发送器，更像是一个用于发送消息的闹钟。我想将我的应用程序连接到手机的电话簿，而不是手动输入，但我不知道如何、在哪里以及放置什么代码。我希望你能帮助我解决这个问题。如果您看到我不知道的错误，请注意。谢谢你。

MainActivity.java：

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import android.app.Dialog; 

public class MainActivity extends Activity


Button btnSendSMS;
EditText txtPhoneNo;
EditText txtMessage;
timeAndDatePicker timeClass = new timeAndDatePicker();
alertFunction alertClass = new alertFunction();

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 

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

btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
txtMessage = (EditText) findViewById(R.id.txtMessage);

btnSendSMS.setOnClickListener(new View.OnClickListener() 

   public void onClick(View v) 
                   
       String phoneNo = txtPhoneNo.getText().toString();
       String message = txtMessage.getText().toString();                 
       if (phoneNo.length()>0 && message.length()>0)                
           sendSMS(phoneNo, message);                
       else
           Toast.makeText(getBaseContext(), 
               "Please enter both phone number and message.", 
               Toast.LENGTH_SHORT).show();

       timeClass.setCurrentDateOnView();
       timeClass.addListenerOnButton();
       alertClass.onCreate();  

   


 private void sendSMS(String phoneNo, String message) 
   String SENT = "SMS_SENT";
   String DELIVERED = "SMS_DELIVERED";

   PendingIntent sentPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(SENT), 0); 

   PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(DELIVERED), 0); 

   // ---when the SMS has been sent---
   registerReceiver(new BroadcastReceiver() 
       @Override
       public void onReceive(Context arg0, Intent arg1) 
           switch (getResultCode()) 
               case Activity.RESULT_OK:
                   Toast.makeText(getBaseContext(), "SMS sent", Toast.LENGTH_SHORT).show();
                   break;
               case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                   Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
                   break;
               case SmsManager.RESULT_ERROR_NO_SERVICE:
                   Toast.makeText(getBaseContext(), "No service", Toast.LENGTH_SHORT).show();
                   break;
               case SmsManager.RESULT_ERROR_NULL_PDU:
                   Toast.makeText(getBaseContext(), "Null PDU", Toast.LENGTH_SHORT).show();
                   break;
               case SmsManager.RESULT_ERROR_RADIO_OFF:
                   Toast.makeText(getBaseContext(), "Radio off", Toast.LENGTH_SHORT).show();
                   break;
           
       
   , new IntentFilter(SENT));

   // ---when the SMS has been delivered---
   registerReceiver(new BroadcastReceiver() 
       @Override
       public void onReceive(Context arg0, Intent arg1) 
           switch (getResultCode()) 
               case Activity.RESULT_OK:
                   Toast.makeText(getBaseContext(), "SMS delivered", Toast.LENGTH_SHORT).show();
                   break;
               case Activity.RESULT_CANCELED:
                   Toast.makeText(getBaseContext(), "SMS not delivered", Toast.LENGTH_SHORT).show();
                   break;
           
       
   , new IntentFilter(DELIVERED));

   SmsManager sms = SmsManager.getDefault();
   sms.sendTextMessage(phoneNo, null, message, sentPI, deliveredPI);


);

我找到了一些有关如何呼叫联系人的答案，但我不知道将这些答案插入我的代码中的什么位置。这让我很困惑。

【参考方案1】：

使用此代码...

ContentResolver contactResolver = getContentResolver(); 
Cursor cursor = contactResolver.query(Phone.CONTENT_URI, null, Phone.DISPLAY_NAME + "=?",          new String[]contactName, null);

if(cursor.getCount() > 0)
cursor.moveToFirst();
do 
   String number = cursor.getString(mCursor.getColumnIndex(Phone.NUMBER));
while (cursor.moveToNext() );

非常感谢您的回答，但我还有另一个问题。我是初学者，我不打算在我的 MAinActivity 中放置您的代码。
