自定义LayoutAnimationController,可任意定制ViewGroup实例内部子View的动画执行顺序,1行代码就让你的ViewGroup拥有华丽的布局动画!
简书:Android开源之ILayoutAnimationController,1行代码让你的ViewGroup拥有华丽的布局动画!
-
1:{@link ILayoutAnimationController#generateController(Animation, float, ILayoutAnimationController.IndexAlgorithm)}
-
2:{@link android.view.ViewGroup#setLayoutAnimation(LayoutAnimationController)}
-
{@link ILayoutAnimationController#setLayoutAnimation(ViewGroup, int, float, ILayoutAnimationController.IndexAlgorithm)}
-
{@link ILayoutAnimationController#setLayoutAnimation(ViewGroup, Animation, float,ILayoutAnimationController.IndexAlgorithm)}
LinearLayout ll = (LinearLayout) findViewById(R.id.ll);
//两行代码设置布局动画:
ILayoutAnimationController controller = ILayoutAnimationController.generateController(AnimationUtils.loadAnimation(this,R.anim.activity_open_enter),0.8f,ILayoutAnimationController.IndexAlgorithm.INDEXSIMPLEPENDULUM);
ll.setLayoutAnimation(controller);
//一行代码直接搞定:
ILayoutAnimationController.setLayoutAnimation(ll,R.anim.activity_open_enter,0.8f,ILayoutAnimationController.IndexAlgorithm.INDEXSIMPLEPENDULUM);
方法setLayoutAnimation中各参数介绍:
/**
* 根据传入的动画资源ID、单个子View动画延时、子View动画执行顺序算法枚举值 创建一个新的CustomLayoutAnimationController实例,
* 将此实例作为参数为viewGroup设置布局动画
* @param viewGroup
* @param animResId
* @param delay
* @param indexAlgorithm
*/
public static void setLayoutAnimation(@NonNull ViewGroup viewGroup,@AnimRes int animResId, float delay,@Nullable final IndexAlgorithm indexAlgorithm){
Animation animation = AnimationUtils.loadAnimation(viewGroup.getContext(),animResId);
setLayoutAnimation(viewGroup,animation,delay,indexAlgorithm);
}
- 使用ILayoutAnimationController获取的ILayoutAnimationController实例,调用setOrder(int order)方法无效!
