Fresco对Listview等快速滑动时停止加载

Posted 2020-09-07 一点点征服

Fresco中在listview之类的快速滑动时停止加载,滑动停止后恢复加载：

1.设置图片请求是否开启

[java] view plain copy print?

1. // 暂停图片请求  
2. public static void imagePause() {  
3.     Fresco.getImagePipeline().pause();  
4. }  
5.   
6. // 恢复图片请求  
7. public static void imageResume() {  
8.     Fresco.getImagePipeline().resume();  
9. }  

2.设置ListView滚动监听

[java] view plain copy print?

1. <pre name="code" class="java"><pre name="code" class="java">mListView.setOnScrollListener(new AbsListView.OnScrollListener() {  
2.     @Override  
3.     public void onScrollStateChanged(AbsListView view, int scrollState) {  
4.         switch(scrollState){  
5.             case AbsListView.OnScrollListener.SCROLL_STATE_IDLE://空闲状态  
6.                 imageResume();  
7.                 break;  
8.             case AbsListView.OnScrollListener.SCROLL_STATE_FLING://滚动状态  
9.                 imagePause();  
10.                 break;  
11.             case AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL://触摸后滚动  
12.                 break;  
13.         }  
14.     }  
15.     public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {  
16.   
17.     }  
18. });  

就是这么多，赶紧试试吧！
