滑块总是在顶部 - 不能移动

Question

我想让我的滑块始终位于顶部。 - 已经完成了。 但我不能让他动起来。我应该做些什么改变？

public class SliderOnTop extends Service {
    private SeekBar seekBar;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

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

        WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
                PixelFormat.TRANSLUCENT);
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);

        RelativeLayout layout = new RelativeLayout(this);
        layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

        seekBar = new SeekBar(this);
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, 45);

        lp.bottomMargin = 0;
        lp.leftMargin = 0;

        layout.addView(seekBar, lp);

        wm.addView(layout, params);

    }

}

您可以在onTouch上收听View个事件，然后相应地更改边距。
