Android中实现滑动翻页—使用ViewFlipper

理论：http://blog.csdn.net/arui319/article/details/7210163

代码如下：

public class ViewFlipperActivity extends Activity implements OnGestureListener {

private static final int FLING_MIN_DISTANCE = 100;

private ViewFlipper flipper;

private GestureDetector detector;

private int[] resuorce = new int[]{R.drawable.jt1,R.drawable.jt2,R.drawable.jt3,R.drawable.jt4,

R.drawable.jt5,R.drawable.jt6,R.drawable.jt7};

protected void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.view_sns_activity);

/*

* 注册一个GestureDetector

*/

detector = new GestureDetector(this);

flipper = (ViewFlipper) findViewById(R.id.viewFlipper1);

for (int i = 0; i < resuorce.length; i++)

{

ImageView image = new ImageView(this);

image.setBackgroundResource(resuorce[i]);

flipper.addView(image);

}

}

public boolean onTouchEvent(MotionEvent event)

{

/*

* 将触屏事件交给手势识别类处理

*/

return this.detector.onTouchEvent(event);

}

public boolean onDown(MotionEvent e) {

return false;

}

public void onShowPress(MotionEvent e) {

}

public boolean onSingleTapUp(MotionEvent e) {

return false;

}

public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {

return false;

}

public void onLongPress(MotionEvent e) {

}

/*

*

*/

public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)

{

boolean is_fling = false;

if (e1.getX() - e2.getX() > FLING_MIN_DISTANCE)

{

/*

* 设置View进入和退出的动画效果

*/

this.flipper.setInAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_in));

this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_out));

this.flipper.showNext();

is_fling = true;

}

if (e1.getX() - e2.getX() < -FLING_MIN_DISTANCE)

{

this.flipper.setInAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_in));

this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_out));

this.flipper.showPrevious();

is_fling = true;

}

return is_fling;

}

}
