Question

我试图在其中创建一个始终操作顶视图并放置图像.... 代码运行没有任何错误。

问题在于 btn1 TouchListener，当用户触摸按钮时ImageView随之移动，但ImageView首先跳转到屏幕的末尾然后开始在屏幕上移动而图像视图不在目前在用户接触的地方移动.... IamgeView套装的Y没有任何问题，但X当前不适合。

这是我的代码：

public class OverlayService extends Service {

LinearLayout lView;
TouchImageView oView;    //My Custom Image View
WindowManager wm;
Button btn1;
WindowManager.LayoutParams params;
Bitmap a;

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

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    sendNotification();

    isRun=true;

    //Get A Bitmap For Imageview
    clashbaz.irana.ir.clashbaz.Bitmap mbit = new clashbaz.irana.ir.clashbaz.Bitmap();

    a = mbit.imageFromAsset(intent.getStringExtra("data"),getApplicationContext());

    oView.viewHeight = a.getHeight();
    oView.viewWidth = a.getWidth();

    lView.addView(btn1);
    lView.addView(oView);

    params = new WindowManager.LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_PHONE,
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
            | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
            PixelFormat.TRANSLUCENT);

    wm = (WindowManager) getSystemService(WINDOW_SERVICE);

    params.gravity = Gravity.START | Gravity.LEFT;
    wm.addView(lView, params);
    oView.setImageDrawable(new BitmapDrawable(a)); // Image Resource
    wm.updateViewLayout(lView, params);
    return START_STICKY;
}

@Override
public void onCreate() {
    super.onCreate();
    lView = new LinearLayout(this);
    lView.setOrientation(LinearLayout.VERTICAL);

    oView = new TouchImageView(this);
    oView.isFocusable();
    btn1 = new Button(this);
    btn1.setText("Move");
    btn1.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent e) {
            if (e.getAction() == MotionEvent.ACTION_MOVE) {
                params.x = (int) e.getRawX();
                params.y = (int) e.getRawY();
                wm.updateViewLayout(lView, params);
            }
            return false;
        }
    });

}

我第一次触摸视图：

当我移动视图时：

最后，我找到答案为詹姆斯说here。

只需添加Gravity.TOP | Gravity.LEFT Insted of Gravity.START | Gravity.LEFT

android - 覆盖服务移动视图
