我正在尝试一整天，但是我的广播接收器在按下媒体按钮时没有收到任何信息
我在下面粘贴代码：
来自我的onCreate（）我的服务：
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mProximity = mSensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
context = getApplicationContext();
am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
：
protected void onHandleIntent(Intent intent) {
am.registerMediaButtonEventReceiver(new ComponentName(this, RemoteReceiver.class));
while(check){
try{
switch(ac_time){
case 15 : Thread.sleep(15000);
break;
case 30: Thread.sleep(30000);
break;
case 60 : Thread.sleep(60000);
break;
case 120: Thread.sleep(120000);
break;
case 300: Thread.sleep(300000);
break;
}
}
catch (InterruptedException e) {
e.printStackTrace();
}
if(!pm.isScreenOn())
break;
}
Log.d("service1", "Screen is now off!");
if(check)
mSensorManager.registerListener(Myservice.this, mProximity, SensorManager.SENSOR_DELAY_NORMAL);
while(check){
Log.d("service1", "Maximum Value: " +mProximity.getMaximumRange());
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
@Override
public void onSensorChanged(SensorEvent event) {
Log.d("service1", "Current value is:" +event.values[0] );
}
am.unregisterMediaButtonEventReceiver(new ComponentName(this, RemoteReceiver.class));
mSensorManager.unregisterListener(this);
来自清单：
<receiver android:name=".RemoteReceiver"
android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON"/>
</intent-filter>
</receiver>
来自收件人班：
public class RemoteReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Log.d("service1", "Broadcast recieved");
if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) {
KeyEvent event = (KeyEvent)intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if ( event.getKeyCode()==KeyEvent.KEYCODE_VOLUME_UP) {
Log.d("service1","Volume Up Pressed");
context.stopService(intent);
}
if ( event.getKeyCode()==KeyEvent.KEYCODE_VOLUME_DOWN) {
Log.d("service1","Volume Down Pressed");
context.stopService(intent);
}
if ( event.getKeyCode()==KeyEvent.KEYCODE_POWER) {
Log.d("service1","Power Pressed");
context.stopService(intent);
}
}
在按下音量按钮和激活服务后，我没有从接收器类获取任何日志，而接近传感器正在提供日志。
有什么帮助吗？
更新：
我也发布了一个日志，以防万一：
