Question

对不起，我英语不好需要一个可以在所有窗口上运行的计时器。只需轻按一下，即可开始/暂停，双击-重置。计时器本身没有问题。在所有窗口之上工作-我正在使用WindowManager。

但是我有一个问题。我开始活动，其中所有窗口上方都设有“重置”按钮和计时器。但是我不知道如何使它们工作。

另外，执行计时器功能的类可以正常工作，但是我不知道如何将其附加到所有窗口顶部的活动上。

这就是我在所有窗户上所做的事情 FloatButtonService.java

public class FloatButtonService extends Service {

@Override
public IBinder onBind(Intent intent) {
    return null;
}
private WindowManager windowManager;
private View rootView;

@Override
public void onCreate() {
    super.onCreate();

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

    int layout_parms;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
    {
        layout_parms = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
    }
    else {
        layout_parms = WindowManager.LayoutParams.TYPE_PHONE;
    }

    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            layout_parms,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT );

    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;

    rootView = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.activity_timer, null);

    windowManager.addView(rootView, params);

    Button mButtonStartPause = rootView.findViewById(R.id.button_start_pause);
    mButtonStartPause.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(FloatButtonService.this, timer.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        }
    });

    rootView.setOnTouchListener(new View.OnTouchListener() {
        private int initialX;
        private int initialY;
        private float initialTouchX;
        private float initialTouchY;
        private boolean shouldClick;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    shouldClick = true;
                    initialX = params.x;
                    initialY = params.y;
                    initialTouchX = event.getRawX();
                    initialTouchY = event.getRawY();
                    return true;
                case MotionEvent.ACTION_UP:
                    if(shouldClick)
                        return true;
                case MotionEvent.ACTION_MOVE:
                    shouldClick = false;
                    params.x = initialX
                            + (int) (event.getRawX() - initialTouchX);
                    params.y = initialY
                            + (int) (event.getRawY() - initialTouchY);
                    windowManager.updateViewLayout(rootView, params);
                    return true;
            }
            return false;
        }
    });

}

@Override
public void onDestroy() {
    super.onDestroy();
    if (rootView != null)
        windowManager.removeView(rootView);
}
