图形布局显示ViewFlipper的第一个视图,如何查看其他视图？

ViewFlipper viewFlipper = (ViewFlipper) findViewById(R.id.view_flipper);
viewFlipper.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View view, MotionEvent motionEvent) {
        if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
            // 获取手势滑动的起始位置
            startX = motionEvent.getX();
        } else if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
            // 获取手势滑动的结束位置
            float endX = motionEvent.getX();
            // 如果手势滑动的距离大于等于屏幕宽度的一半，则切换到下一个视图
            if (endX - startX >= screenWidth / 2) {
                viewFlipper.setInAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.in_from_right));
                viewFlipper.setOutAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.out_to_left));
                viewFlipper.showNext();
            } else if (startX - endX >= screenWidth / 2) {
                viewFlipper.setInAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.in_from_left));
                viewFlipper.setOutAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.out_to_right));
                viewFlipper.showPrevious();
            }
        }
        return true;
    }
});
