关于android LinearLayout的比例布局

关于android LinearLayout的比例布局，主要有以下三个属性需要设置：

     1，android:layout_width，android:layout_height,android:layout_weight三个值

     2，当为水平布局时，android:layout_height=“0dp",当为垂直布局时，android:layout_width="0dp"，android:layout_weight为所占比重。

     3，给个示例如下：

< LinearLayout
             android:orientation ="horizontal"
             android:layout_width ="fill_parent"
             android:layout_height ="fill_parent"
             android:layout_weight ="1" >
             < TextView
                     android:layout_width ="0dp"
                     android:layout_height ="fill_parent"
                     android:layout_weight ="1"
                     android:background ="#aa0000"
                     android:gravity ="center"
                     android:text ="1111111111111111111111111111111111111111111" />
             < TextView
                     android:layout_width ="0dp"
                     android:layout_height ="fill_parent"
                     android:layout_weight ="2"
                     android:background ="#00aa00"
                     android:gravity ="center"
                     android:text ="2" />
             < TextView
                     android:layout_width ="0dp"
                     android:layout_height ="fill_parent"
                     android:layout_weight ="3"
                     android:background ="#0000aa"
                     android:gravity ="center"
                     android:text ="3" />
     </ LinearLayout >

效果：
