android - TelephonyManager.CALL_STATE_IDLE 多次调用

Question

我有一个类，一个电话状态的监听器。在此，当调用断开此线路时，

case TelephonyManager.CALL_STATE_IDLE:
Log.e(TAG, "CALL_STATE_IDLE");
break;

执行不止一次。这严重影响了我的要求。如果有人知道这个问题，请帮助我。

将您的代码更改为:

public class IncomingCallListener extends BroadcastReceiver
        {
            private Context mContext;

            private static final String TAG = "CustomBroadcastReceiver";
        @Override
        public void onReceive(Context context, Intent intent) 
        {
            mContext = context;
            Bundle extras = intent.getExtras();
            if (extras != null) {
            String state = extras.getString(TelephonyManager.EXTRA_STATE);
            Log.w("DEBUG", state);
            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
            {
                TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
                CustomPhoneStateListener customPhoneListener = new   CustomPhoneStateListener();
                telephony.listen(customPhoneListener,   PhoneStateListener.LISTEN_CALL_STATE);
                Bundle bundle = intent.getExtras();
                String phoneNr= bundle.getString("incoming_number");
            }
            else{
                        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
                            {
                               // DO SOME CODE HERE...
                            }
                        else{
                        if (state.equals(TelephonyManager.CALL_STATE_OFFHOOK))
                            {
                               // DO SOME CODE HERE...
                            }                          
                        }
            }
        }

     }
