本文详细介绍了Android应用开发中Fragment的生命周期，包括从onAttach到onDestroy的各个阶段，并展示了如何通过代码跟踪这些生命周期方法的调用顺序。

fragment 自身的生命周期

写了一个BlankFragment 继承fragment
className:BlankFragment MethodName: onAttach
className:BlankFragment MethodName: onCreate
className:BlankFragment MethodName: onCreateView
className:BlankFragment MethodName: onActivityCreated
className:BlankFragment MethodName: onStart
className:BlankFragment MethodName: onResume
className:BlankFragment MethodName: onPause
className:BlankFragment MethodName: onStop
className:BlankFragment MethodName: onDestroyView
className:BlankFragment MethodName: onDestroy
className:BlankFragment MethodName: onDetach

xml代码：

生命周期：
className:BlankFragment MethodName: onAttach
className:BlankFragment MethodName: onCreate
className:BlankFragment MethodName: onCreateView
className:MainActivity MethodName: onCreate
className:BlankFragment MethodName: onActivityCreated
className:BlankFragment MethodName: onStart
className:MainActivity MethodName: onStart
className:MainActivity MethodName: onResume
className:BlankFragment MethodName: onResume
className:BlankFragment MethodName: onPause
className:MainActivity MethodName: onPause
className:BlankFragment MethodName: onStop
className:MainActivity MethodName: onStop
className:BlankFragment MethodName: onDestroyView
className:BlankFragment MethodName: onDestroy
className:BlankFragment MethodName: onDetach
className:MainActivity MethodName: onDestroy
然后再MainActivity中的onCrate方法中添加fargment
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.fragmentGroup,new BlankFragment());
fragmentTransaction.commit();
生命周期:

className:MainActivity MethodName: onCreate
className:BlankFragment MethodName: onAttach
className:BlankFragment MethodName: onCreate
className:BlankFragment MethodName: onCreateView
className:BlankFragment MethodName: onActivityCreated
className:BlankFragment MethodName: onStart
className:MainActivity MethodName: onStart
className:MainActivity MethodName: onResume
className:BlankFragment MethodName: onResume
className:BlankFragment MethodName: onPause
className:MainActivity MethodName: onPause
className:BlankFragment MethodName: onStop
className:MainActivity MethodName: onStop
className:BlankFragment MethodName: onDestroyView
className:BlankFragment MethodName: onDestroy
className:BlankFragment MethodName: onDetach
className:MainActivity MethodName: onDestroy
