android布局中的swipe动画

Question

我了解到动画效果可以运用到布局中，能实现onclicklistener, ontouchlistener事件。
但是不了解当向左边或右边滑动布局时，哪个事件会发生。

previousButton.setOnClickListener(new OnClickListener()  {
      @Override 
        publicvoid onClick(View v) {  
              viewFlipper.setInAnimation(MainActivity.this,R.anim.view_transition_in_right);
               viewFlipper.setOutAnimation(MainActivity.this,R.anim.view_transition_out_right);
               viewFlipper.showPrevious();  
      }  
    });  
}

我不想实现onclicklistener事件。如果我把当前的布局触摸并且滑动到左边，下一个布局就会在当前的视图中。
如何处理这个问题啊？

Answer 1

让activity实现onGestureListener
然后在activity添加

private GestureDetector gestureScanner;
gestureScanner = new GestureDetector(this);
private static final int SWIPE_MIN_DISTANCE = 100;
    private static final int SWIPE_THRESHOLD_VELOCITY = 100;

重写onTouchEvent(MotionEvent event)

@Override
    public boolean onTouchEvent(MotionEvent event) {
        return gestureScanner.onTouchEvent(event);
    }

最后也要重写onFling方法

@Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        /* on scroll to the next page */
        if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY
                ) {
            //Ur code goes here
        }
        /* on scroll to the previous page  */
        else if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY
                ) {
            //ur code goes here.
        }
        return false;
    }
