是否有可能使用HandlerThread其內部主UI線程上進一步啓動的服務的BroadcastReceiver 的的onReceive方法??HandlerThread內部的BroadcastReceiver
我的目標是使用HandlerThread內的onReceive方法，使服務得到在單獨的線程啓動。
但不知道如何實現它。
任何提示？
感謝

public class BackgroundVideoRecorder extends Service implements SurfaceHolder.Callback {
public WindowManager windowManager;
public SurfaceView surfaceView;
public Camera camera = null;
public MediaRecorder mediaRecorder = null;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
// Create new SurfaceView, set its size to 1x1, move it to the top left corner and set this service as a callback
windowManager = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
surfaceView = new SurfaceView(getApplicationContext());
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams(
1, 1,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT
);
layoutParams.gravity = Gravity.LEFT | Gravity.TOP;
windowManager.addView(surfaceView, layoutParams);
surfaceView.getHolder().addCallback(this);
}
// Method called right after Surface created (initializing and starting MediaRecorder)
@Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
try {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(getApplicationContext(), CAMERA) == PackageManager.PERMISSION_GRANTED) {
camera = Camera.open();
}else{
// should show permission
}
} else {
camera = Camera.open();
}
mediaRecorder = new MediaRecorder();
camera.unlock();
mediaRecorder.setPreviewDisplay(surfaceHolder.getSurface());
mediaRecorder.setCamera(camera);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_1080P));
mediaRecorder.setOutputFile(
Environment.getExternalStorageDirectory() + "/" +
DateFormat.format("yyyy-MM-dd_kk-mm-ss", new Date().getTime()) +
".mp4"
);
try {
mediaRecorder.prepare();
} catch (Exception e) {
}
mediaRecorder.start();
} catch (Exception e) {
}
}
// Stop recording and remove SurfaceView
@Override
public void onDestroy() {
mediaRecorder.stop();
mediaRecorder.reset();
mediaRecorder.release();
camera.lock();
camera.release();
windowManager.removeView(surfaceView);
}
@Override
public void surfaceChanged(SurfaceHolder surfaceHolder, int format, int width, int height) {
}
@Override
public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
}
}
我想我無法正常使用服務。請幫忙。

爲什麼你想在一個單獨的線程中調用'startService（）'？請解釋。 –
因爲每次運行應用程序時，我的日誌中都會有一條消息。「主線程上的太多東西」以及我的設備速度變慢。 –
你不會通過在另一個線程中調用'startService（）'來解決這個問題。你的問題在別的地方。發佈你的'onStart（）'或'onStartCommand（）'方法的代碼。 –
