ImageSwitcher imageSwitcher = findViewById(R.id.imageSwitcher);

imageSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
    @Override
    public View makeView() {
        ImageView imageView = new ImageView(getApplicationContext());
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setLayoutParams(new ImageSwitcher.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

imageSwitcher.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // 触摸按下事件
                break;
            case MotionEvent.ACTION_MOVE:
                // 触摸移动事件
                break;
            case MotionEvent.ACTION_UP:
                // 触摸抬起事件
