Question

我希望在来电时在我的应用程序中执行一些操作（暂停游戏）。但阅读手机状态无效。我在清单中给了许可（READ_PHONE_STATE）。来电时什么也没发生。感谢。

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;
          }

        }
       };

Answer 1

您是否写过以下内容：

 telephonyManager.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);

Answer 2

当你的监听器被创建时，你需要调用`public void listen（PhoneStateListener listener，int events）'来监听。

另外，你可以试试这个：创建一个广泛的接收器来处理动作android.intent.action.PHONE_STATE，

代码示例：

public class PhoneStateReceiver extends BroadcastReceiver {

private TelephonyManager manager;

@Override
public void onReceive(Context context, Intent intent) {
    if (manager == null) {
        manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    }
    String action = intent.getAction();
    System.out.println(action);
    System.out.println("current phone state:" + manager.getCallState());
}

}
