7.ViewFlipper

 

 

使用ViewFlipper来播放图片 这个控件继承了ViewAnimator

  调用showPrevious显示上一张

  showNext();显示下一张

     startFlipping();开始自动播放

     stopFlipping();停止播放

     设置进入的动画效果与方向

     viewFlipper.setInAnimation(this, android.R.anim.slide_out_right);

     设置切换下一张时的动画效果与方向

         viewFlipper.setOutAnimation(this, android.R.anim.slide_in_left);
