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 >
