当你启动愤怒的小鸟并点击播放时,你会看到一个水平滚动的菜单,其中有一行图像,一旦点击你可以开始游戏,什么不是.我想知道如何使菜单与此类似,因为它横向(水平)滚动并显示可点击的图像？提前致谢!

如何去除画廊图像周围的丑陋灰色边框？

我有一个图像视图,我为我的游戏画了我的游戏板.我需要相对于图像视图获取触摸的X,Y.例如:如果有人触摸了最左上方的Pixel,它将返回(0,0)或者说游戏板是100,100板,我在中间触摸我会得到(50,50)...如何会这样做吗？

 gameView.setOnTouchListener(new OnTouchListener(){

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_DOWN){
            int x = (int) event.getX() / pieceSize;
            int y = (int) event.getY() / pieceSize;
            Log.d("Touch Event", "Touch event at "+ x + " " +y);

            doMove(x, y);

            Log.d("Move", "The move was " + doMove(x,y));
            }
            gameView.setImageBitmap(Draw(pieceSize));

            return true;
        }

    });

ArrayList<String> myArr = new ArrayList<String>();

然后添加一些东西

myArr.add("Hello");
    myArr.add("Testing");
    myArr.add("Testing 1 2 3 ");

然后我尝试通过这样做将它转换为String数组:

String[] s = (String[])myArr.toArray();

我将使用此数组最终填充listview...但是当它投射时会崩溃并抛出它
