android 布局的性能优化

1、布局重用<include />

2、减少视图层级<merge />

3、需要时使用<ViewStub />

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/traffic_layout_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal" >

<include layout="@layout/traffic_layout_title" />

<include layout="@layout/traffic_layout_pull_result" />

<include layout="@layout/traffic_layout_pull" />
