广播接收器调用但PhoneStateListener不叫 [英] BroadcastReceiver called but PhoneStateListener not called

问题描述

在调试code以下，BroadcastReceiverCustom正在
所谓但是PhoneStateListenerCustom不是。

现在我只有在BroadcastReceiverCustom做必要的行动，
但maynot要做到这一点最好的地方。
任何建议，为什么不PhoneStateListener被称为？
已经花了很多时间了解可能的原因，也不知道？
清单文件是使用正确的权限正确的。
我看没有运行时异常。

解决方案

你不应该实例中的BroadcastReceiver的TelephonyManager和PhoneStateListener。这里是一些例子code：

在活动：

  EndCallListener callListener =新EndCallListener;
TelephonyManager MTM =（TelephonyManager）this.getSystemService（Context.TELEPHONY_SERVICE）;
mTM.listen（callListener，PhoneStateListener.LISTEN_CALL_STATE）;私有类EndCallListener扩展PhoneStateListener {
    @覆盖
    公共无效onCallStateChanged（INT状态，弦乐incomingNumber）{
        如果（TelephonyManager.CALL_STATE_RINGING ==州）{
            Log.i（LOG_TAG +监听器​​，响个不停，数：+ incomingNumber）;
        }
        如果（TelephonyManager.CALL_STATE_OFFHOOK ==州）{
            Log.i（LOG_TAG +监听器​​，摘机，数：+ incomingNumber）;
        }
        如果（TelephonyManager.CALL_STATE_IDLE ==州）{
            Log.i（LOG_TAG +监听器​​，IDLE，数：+ incomingNumber）;
        }
    }
}
 

While debugging the code below, BroadcastReceiverCustom is being called but PhoneStateListenerCustom is not.

For now I and doing required action in BroadcastReceiverCustom only, but maynot be best place to do it. Any suggestions why PhoneStateListener not being called?? Already spent lot of time for possible reasons, no idea?? Manifest file is all correct with correct permissions. I see no runtime exceptions.

BroadcastReceiverCustom.java

public class BroadcastReceiverCustom extends BroadcastReceiver {

private static final String TAG = "BroadcastReceiverCustom";

    @Override
    public void onReceive(Context context, Intent intent) {

        Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");

        TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        PhoneStateListenerCustom phoneStateListenerCustom = new PhoneStateListenerCustom();
        telephony.listen(phoneStateListenerCustom, PhoneStateListener.LISTEN_CALL_STATE);
    }
}

PhoneStateListenerCustom.java

public class PhoneStateListenerCustom extends PhoneStateListener {

    private static final String TAG = "PhoneStateListenerCustom";

    public void onCallStateChange(int state, String incomingNumber){

        Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");
        switch(state){
            case TelephonyManager.CALL_STATE_RINGING:
                 Log.d(TAG, "RINGING");
                 break;
        }

        super.onCallStateChanged(state, incomingNumber);

    }
}

Manifest file

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<receiver android:name=".BroadcastReceiverCustom">
    <intent-filter>
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>

解决方案

you should not instantiate the TelephonyManager and PhoneStateListener in the BroadcastReceiver. here is some example code:

in Activity:

EndCallListener callListener = new EndCallListener;
TelephonyManager mTM = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);

private class EndCallListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        if(TelephonyManager.CALL_STATE_RINGING == state) {
            Log.i(LOG_TAG + "Listener", "RINGING, number: " + incomingNumber);
        }
        if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
            Log.i(LOG_TAG + "Listener", "OFFHOOK, number: " + incomingNumber);
        }
        if(TelephonyManager.CALL_STATE_IDLE == state) {
            Log.i(LOG_TAG + "Listener", "IDLE, number: " + incomingNumber);
        }
    }
}
