一般的Animation有以下四种类型：
1. Alpha：渐变透明度动画效果
2. Scale：渐变尺寸伸缩动画效果
3. Translate：画面转换位置移动动画效果
4. Rotate：画面转换位置移动动画效果

//主要是这个方法，其它方法都是不需要写代码的。不过看个人需求吧。
@Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
if (e1.getX() - e2.getX() > 50) {
this._viewFlipper.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in));
this._viewFlipper.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_out));
this._viewFlipper.showNext(); return true;
} else if (e1.getX() - e2.getX() < -50) {
this._viewFlipper.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_right_in));
this._viewFlipper.setOutAnimation(AnimationUtils.loadAnimation(this,R.anim.push_right_out)); this._viewFlipper.showPrevious(); return true; } return false;
}
@Override public void onLongPress(MotionEvent e) {
}
@Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
return false; }
@Override public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub }
@Override public boolean onSingleTapUp(MotionEvent e) { // TODO Auto-generated method stub return false; }
//研究了好久。
滑动跳转为activity:
继承extends ActivityGroup
然后：
_viewFlipper.addView(getLocalActivityManager().startActivity("", new Intent(MainUiActivity.this, GridViewMore.class)).getDecorView(), 0); _viewFlipper.addView(getLocalActivityManager().startActivity("", new Intent(MainUiActivity.this,GridViewIntroduce.class)).getDecorView(),
1); _viewFlipper.setDisplayedChild(0);
其余代码不变！
