Question

public void onReceive(Context context, Intent intent) { 
context.startService(new Intent(context,MyPhoneStateListener.class));    
MyPhoneStateListener lst=new MyPhoneStateListener(context); 
TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);   
telephonyManager.listen(lst, PhoneStateListener.LISTEN_CALL_STATE); 
} 

public IBinder onBind(Intent arg0)
 { // TODO Auto-generated method stub return null; 

} 
}

   // class MyPhoneStateListener extends PhoneStateListener
{ 
  //private static final String TAG = "PhoneStateChanged"; 
   Context context; 
  //Context to make Toast if required 
  public MyPhoneStateListener(Context context) 
  { 
  super(); 
  this.context = context; 
  } 

 @Override 
 public void onCallStateChanged(int state, String incomingNumber) {  
 super.onCallStateChanged(state, incomingNumber); 

 switch (state)
  { 
  case TelephonyManager.CALL_STATE_IDLE: //when Idle i.e no call 
  Toast.makeText(context, "Phone state Idle", Toast.LENGTH_LONG).show(); 
   break; 
  case TelephonyManager.CALL_STATE_OFFHOOK: //when Off hook i.e in call //Make intent and start your service here Toast.makeText(context, "Phone state Off hook", Toast.LENGTH_LONG).show(); 
   break; 
  case TelephonyManager.CALL_STATE_RINGING: //when Ringing Toast.makeText(context, "Phone state Ringing", Toast.LENGTH_LONG).show();
   break; 
  default: break; 
 } } }

想要开发一个在用户调用时结束调用的应用程序，首先它应该从数据库中检测是否存储了该号码。这将是更好的主意。使用服务或广播接收器。结束通话请帮助我在过去一周尝试的代码。我使用了广播接收器，但是当呼叫进入时，这种情况没有帮助，其他活动除了接收器之外还有效。

Answer 1

我假设您要拨打拨出电话以防被叫号码不在列表中：

您需要在清单中注册接收器：

    <receiver
        android:exported="true"
        android:name=".receiver.OutgoingCall" >
        <intent-filter android:priority="0" >
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>
