我想执行一些操作（暂停游戏）在我的应用程序时，一个电话来了。但是，在手机阅读状态，无法正常工作。我已在清单中的权限（READ_PHONE_STATE）。没有什么是发生在一个电话来了。 谢谢你。

  TelephonyManager telephonyManager;
PhoneStateListener监听;
telephonyManager =（TelephonyManager）getSystemService（Context.TELEPHONY_SERVICE）;

监听=新PhoneStateListener（）{

        公共无效onCallStateChanged（INT状态，串incomingNumber）{

        开关（州）{

解决方案

您写了下面的一行：

  telephonyManager.listen（监听器，PhoneStateListener.LISTEN_CALL_STATE）;
 

I want to perform some operation (Pause game) in my application when a call came. But reading the phone state is not working. I have given permission(READ_PHONE_STATE) in the manifest. Nothing is happen when a call came. Thanks.

TelephonyManager telephonyManager;
PhoneStateListener listener;
telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
*
*
*
listener = new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {

        switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:
            Toast.makeText(SudokuGameActivity.this, "IDLE", Toast.LENGTH_SHORT).show();
          break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
         Toast.makeText(SudokuGameActivity.this, "OFF Hook", Toast.LENGTH_SHORT).show();
          break;
        case TelephonyManager.CALL_STATE_RINGING:
            Toast.makeText(SudokuGameActivity.this, "Ringing", Toast.LENGTH_SHORT).show();
            mpauseButton.performClick();
          break;
          }

        }
       };

Have you written the following line :

 telephonyManager.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);
