如何检查是否单击了耳机中的播放/暂停按钮?在那之后我可以实现一些可以改变我自己的动作(关闭等)的典型动作(播放/暂停)的方法吗?

现在我正在使用下面的代码耳机按钮单击事件,它对我有用。试试这个代码

// Receiver
public class MediaButtonEventReceiver extends BroadcastReceiver {

    private static final String TAG = "MediaButtonIntentReceiv";
    public MediaButtonIntentReceiver() {
        super();
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        String intentAction = intent.getAction();
        if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
            return;
        }
        KeyEvent event = (KeyEvent)intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
        if (event == null) {
            return;
        }

        int action = event.getAction();
        if (action == KeyEvent.ACTION_DOWN) {
            // do something
            Log.e(TAG, "onReceive: " );
            Toast.makeText(context, "BUTTON PRESSED!", Toast.LENGTH_SHORT).show();
        }


        abortBroadcast();
    }
}
// Write this code in onCreateview in your activity 

IntentFilter filter = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);
MediaButtonIntentReceiver r = new MediaButtonIntentReceiver();
filter.setPriority(1000); //this line sets receiver priority
registerReceiver(r, filter);
//  manifest.xml 
 <receiver android:name=".MediaButtonIntentReceiver">
            <intent-filter >
                <action android:name="android.intent.action.MEDIA_BUTTON"/>
            </intent-filter>
 </receiver>

如果您试图从前台的活动中侦听此内容,请使用onKeyDown()并注意KEYCODE_MEDIA_PLAY_PAUSE.

如果您尝试从后台收听此事件(例如,播放音乐的服务),请使用BroadcastReceiverfor 。ACTION_MEDIA_BUTTON
