首先看下生命周期图：
接下来代码演示：
fragment_life_circle.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="fragment life circle"/>
</LinearLayout> |
