我写了一些服务,它使用BroadcastReceiver来捕获媒体按钮之一。我只有在音乐播放器处于非活动状态时才能捕获媒体按钮事件。当我的音乐播放器处于活动状态时,如何捕获媒体按钮事件..!
MyActivity:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about_and_activation_view);
Log.d("MR", "onCreate - " + getIntent().getAction());
AudioManager mAudioManager = (AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
ComponentName mediaButtonReceiver = new ComponentName(getPackageName(), HeadsetControlEventReceiver.class.getName());
mAudioManager.registerMediaButtonEventReceiver(mediaButtonReceiver);
}
MyBroadcastReceiver:
public class HeadsetControlEventReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
try{
KeyEvent event = (KeyEvent) intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if ((event != null) && (event.getKeyCode() == KeyEvent.KEYCODE_HEADSETHOOK)) {
的Manifest.xml
<receiver
android:name=".HeadsetControlEventReceiver"
android:enabled="true">
<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.MEDIA_BUTTON"/>
</intent-filter>
</receiver>

在您注册并启动音乐播放器后,音乐播放器将获得优先权。现在您需要再次注册。如何使用酷轮询机制。
