[Android]Fragment生命周期

官方文档中有详细的文字说明，不过最好还是实践下，熟悉过程。http://developer.android.com/guide/components/fragments.html

一、Activity的生命周期图：

二、Fragment生命周期图

三、对比图

四、测试代码：

[java] view plain copy

importandroid.widget.ListView;

publicclassFragmentListArrayextendsActivity{
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
Log.e("HJJ","Activity&&&&onCreate...");
//Createthelistfragmentandadditasoursolecontent.
