android - 布局导致空白

Question

我有这个布局，但在运行时，只有当我删除相对和线性布局时，它才会向我显示空白空间，将窗口划分为 4 个 qurters，它显示视图是否有更简洁的方法将屏幕划分为 4 个 qurters。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

要将您的屏幕分成 4 个部分，请执行以下操作：

    <LinearLayout 
       android:layout_height= "match_parent"
       android:layout_width= "match_parent"
       android:orientation = "vertical"
       android:weightSum = "1.0" >

    <!-- first divide this main linear layout into two vertical splits -->  

       <LinearLayout
           android:id="@+id/first_vertical_split"
           android:layout_width ="match_parent"
           android:layout_height ="0dp"
           android:layout_weight = "0.5" >

           <!-- Now split each of these vertical splits horizontally -->   

           <LinearLayout
                android:id="@+id/first_inner_horiz_split"
                android:layout_width ="0dip"
                android:layout_height ="match_parent"
                android:background="@android:color/black"
                android:layout_weight = "0.5">
           </LinearLayout>

           <LinearLayout  
              android:id="@+id/second_inner_horiz_split"
              android:layout_width ="0dip"
              android:layout_height ="match_parent"
              android:layout_weight = "0.5">
           </LinearLayout>            

       </LinearLayout> 

       <LinearLayout 
             android:id="@+id/second_vertical_split"
             android:layout_width ="match_parent"
             android:layout_height ="0dp"
             android:layout_weight = "0.5">

             <LinearLayout
                android:id="@+id/first_inner_horiz_split"
                android:layout_width ="0dip"
                android:layout_height ="match_parent"
                android:layout_weight = "0.5">
             </LinearLayout>

             <LinearLayout
              android:id="@+id/second_inner_horiz_split"  
              android:layout_width ="0dip"
              android:layout_height ="match_parent"
              android:background="@android:color/black"
              android:layout_weight = "0.5">
             </LinearLayout> 

       </LinearLayout>

    </LinearLayout>
