### 根局部为RelativeLayout
1. 开启Activity
```
E/log: Activity生命周期:onCreate
E/view的生命周期: onCreate
E/view的生命周期: onFinishInflate
E/log: Activity生命周期:onStart
E/log: Activity生命周期:onResume
E/view的生命周期: onAttachedToWindow
E/view的生命周期: onMeasure
E/view的生命周期: onMeasure
E/view的生命周期: onSizeChanged
E/view的生命周期: onLayout
E/view的生命周期: onWindowFocusChanged true
E/view的生命周期: onMeasure
E/view的生命周期: onMeasure
E/view的生命周期: onLayout
E/view的生命周期: onDraw
```
2. 关闭Activity
```
E/view的生命周期: onWindowFocusChanged false
E/log: Activity生命周期:onPause
E/log: Activity生命周期:onStop
E/log: Activity生命周期:onDestroy
```
* 开启另外的Activity
1. 开启一个的Activity,使原本的Activity进入onStop
```
E/log: Activity生命周期:onPause
E/view的生命周期: onWindowFocusChanged false
E/log: Activity生命周期:onStop
```
2. 退出这个Activity,使原本的Activity重新进入到前台
```
E/log: Activity生命周期:onRestart
E/log: Activity生命周期:onStart
E/log: Activity生命周期:onResume
E/view的生命周期: onWindowFocusChanged true
E/view的生命周期: onDraw
```
* 开启一个透明的Activity
1. 开启一个透明的Activity,使原本的Activity进入onPause
```
E/log: Activity生命周期:onPause
E/view的生命周期: onWindowFocusChanged false
```
2. 关闭透明的Activity,使原本的Activity,进入onResume
```
E/log: Activity生命周期:onResume
E/view的生命周期: onWindowFocusChanged true
```
### 根局部为LinearLayout ###
* 子控件不含有weight属性
* 这个控件含有weight属性但是它是根布局的唯一子控件
```
E/log: Activity生命周期:onCreate
E/view的生命周期: onCreate
E/view的生命周期: onFinishInflate
E/log: Activity生命周期:onStart
E/log: Activity生命周期:onResume
E/view的生命周期: onAttachedToWindow
E/view的生命周期: onMeasure
E/view的生命周期: onSizeChanged
E/view的生命周期: onLayout
E/view的生命周期: onMeasure
E/view的生命周期: onLayout
E/view的生命周期: onDraw
E/view的生命周期: onWindowFocusChanged true
```
* 控件含有weight属性,并且它不是其根局部中的唯一子控件
```
E/log: Activity生命周期:onCreate
E/view的生命周期: onCreate
E/view的生命周期: onFinishInflate
E/log: Activity生命周期:onStart
E/log: Activity生命周期:onResume
E/view的生命周期: onAttachedToWindow
E/view的生命周期: onMeasure
E/view的生命周期: onSizeChanged
E/view的生命周期: onLayout
E/view的生命周期: onMeasure
E/view的生命周期: onLayout
E/view的生命周期: onDraw
E/view的生命周期: onWindowFocusChanged true
```
> 如果view没有任何没有内容,并且根布局内有其他内容,则最后的onDraw不会执行
```xml
E/log: Activity生命周期:onCreate
E/view的生命周期: onCreate
E/view的生命周期: onFinishInflate
E/log: Activity生命周期:onStart
E/log: Activity生命周期:onResume
E/view的生命周期: onAttachedToWindow
E/view的生命周期: onMeasure
E/view的生命周期: onMeasure
E/view的生命周期: onSizeChanged
E/view的生命周期: onLayout
E/view的生命周期: onWindowFocusChanged true
E/view的生命周期: onMeasure
E/view的生命周期: onMeasure
E/view的生命周期: onLayout
```
```xml
E/log: Activity生命周期:onCreate
E/view的生命周期: onCreate
E/view的生命周期: onFinishInflate
E/log: Activity生命周期:onStart
E/log: Activity生命周期:onResume
E/view的生命周期: onAttachedToWindow
E/view的生命周期: onMeasure
E/view的生命周期: onSizeChanged
E/view的生命周期: onLayout
E/view的生命周期: onWindowFocusChanged true
E/view的生命周期: onMeasure
E/view的生命周期: onLayout
E/view的生命周期: onDraw
```
