Android layout_weight用法圖解

直接上代碼和圖片。

情況一:

[html]  <?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal" > 
 
    <fragment 
        android:id="@+id/titles" 
        android:layout_width="0dip" 
        android:layout_height="match_parent" 
        android:layout_weight="1" 
        class="com.a2bgeek.fragmentdemo.TitlesFragment" /> 
 
    <FrameLayout 
        android:id="@+id/details" 
        android:layout_width="0dip" 
        android:layout_height="match_parent"

    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <fragment
        android:id="@+id/titles"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        class="com.a2bgeek.fragmentdemo.TitlesFragment" />

    <FrameLayout
        android:id="@+id/details"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="2" >
    </FrameLayout>

</LinearLayout>
 

<?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="horizontal" >

    <fragment
        android:id="@+id/titles"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        class="com.a2bgeek.fragmentdemo.TitlesFragment" />

    <FrameLayout
        android:id="@+id/details"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="2" >
    </FrameLayout>

</LinearLayout>


 

情況三:

Fragment這個東西在wrap_content的情況下會占據全部,和控件不太一樣。
