懒加载Fragment

只有创建并显示的时候才会调用onCreateViewLazy方法
12 | *
13 | *

14 | * 懒加载的原理onCreateView的时候Fragment有可能没有显示出来。
15 | * 但是调用到setUserVisibleHint(boolean isVisibleToUser),isVisibleToUser = 16 | * true的时候就说明有显示出来
17 | * 但是要考虑onCreateView和setUserVisibleHint的先后问题所以才有了下面的代码 18 | *

19 | * 注意:
20 | * 《1》原先的Fragment的回调方法名字后面要加个Lazy,比如Fragment的onCreateView方法, 就写成onCreateViewLazy
21 | * 《2》使用该LazyFragment会导致多一层布局深度 22 | * 23 | * @author LuckyJayce 24 | */ 25 | public class LazyFragment extends BaseFragment { 26 | private boolean isInit = false;//真正要显示的View是否已经被初始化(正常加载) 27 |
