Java Android OnTouch同步触摸

我的活动中有一个OnTouchListener，它被设置在一个布局和其他5个按钮上，如果你一个接一个地/单独按下它们，它们工作得很好，但是如果我想按下一个按钮，并且仍然在布局上移动手指，它将无法工作，直到我从按钮上松开手指。 如何使用OnTouch，以便可以同时使用几个视图

@Override
public boolean onTouch(View v, MotionEvent event){
    switch (v.getId()) {

        case R.id.layout:

            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                // On click on screen
                oldX = (int) event.getX(); // set first click X as old
                oldY = (int) event.getY(); // set first click Y as old
                isClicked = true;
                return true;
            }

            else if (event.getAction() == MotionEvent.ACTION_MOVE) {
                isClicked = false;

                // On finger move on screen
                newX = (int) event.getX(); // set current X
                newY = (int) event.getY(); // set current Y

                diff[0] = newX - oldX; // Set X difference
                diff[1] = newY - oldY; // Set y difference

                oldX = newX; // set current X as last X
                oldY = newY; // set current Y as last Y

                // Send to server
                new UDP_handler(IPAddr, port).execute("MOVE|" + diff[0] + "," + diff[1]);

                return true;
            }

            else if(event.getAction() == MotionEvent.ACTION_UP){
                if (isClicked)
                    new UDP_handler(IPAddr, port).execute("CLICK|LC");
                return true;    
            }

            break;

        case R.id.Button0:
            if (event.getAction() == MotionEvent.ACTION_UP){
                new UDP_handler(IPAddr, port).execute("CLICK|MUP");
                return true;    
            }
            break;

        case R.id.Button1:
            if (event.getAction() == MotionEvent.ACTION_UP){
                new UDP_handler(IPAddr, port).execute("CLICKUP|LC");
                return true;    
            }
            else if(event.getAction() == MotionEvent.ACTION_DOWN){
                new UDP_handler(IPAddr, port).execute("CLICKDOWN|LC");
                return true;    
            }
            break;

        case R.id.Button2:
            if (event.getAction() == MotionEvent.ACTION_UP){
                new UDP_handler(IPAddr, port).execute("CLICK|MC");
                return true;
            }
            break;

        case R.id.Button3:
            if (event.getAction() == MotionEvent.ACTION_UP){
                new UDP_handler(IPAddr, port).execute("CLICK|RC");
                return true;
            }
            break;

        case R.id.Button4:
            if (event.getAction() == MotionEvent.ACTION_UP){
                new UDP_handler(IPAddr, port).execute("CLICK|MDOWN");
                return true;    
            }
            break;

        default:
            break;
    }
    return false;
}

（我想按下R.id.button1，同时在R.id.layout上移动我的手指，查看它的上下动作）

也许可以使用GestureOverlay？@MichałSzydłowski我不知道如何像在onTouch功能中那样使用它
