I see 4 relativelayouts in your drawing...?

If you mean the two in the middle put them into one LinearLayout (horizontal orientation), let all of them have a width of match_parent and give both relative layouts a weight of 1

blocks|key|4703076|text|您可以将这两个RelativeLayouts放入一个具有水平方向的LinearLayout中，然后将weight用于这两个RelativeLayouts。这将把LinearLayout分成两个相等的部分。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4703077|<LinearLayout

You can put these 2 RelativeLayouts inside a LinearLayout with horizontal orientation, then use the <a href="http://developer.android.com/guide/topics/ui/layout/linear.html#Weight" rel="noreferrer">weight</a> for both RelativeLayouts. This will divide the LinearLayout in 2 equal parts.

<pre><code>&lt;LinearLayout
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="horizontal"
 android:baselineAligned="false"&gt;
 &lt;RelativeLayout
 android:layout_width="0dp"
 android:layout_height="wrap_content"
 android:layout_weight="1"&gt;
 &lt;/RelativeLayout&gt;
 &lt;RelativeLayout
 android:layout_width="0dp"
 android:layout_height="wrap_content"
 android:layout_weight="1"&gt;
 &lt;/RelativeLayout&gt;
&lt;/LinearLayout&gt;
</code></pre>

blocks|key|197188|text|完成相同任务而不需要使用LinearLayout的另一种方法是在父布局的中间放置一个居中对齐的“填补”，然后将其他元素与其对齐。如果将半宽元素的宽度设置为match_parent，但将其左右两边对齐，则它们最终会自动收缩以适应需要。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|197189|<RelativeLayout+xmlns:android="http://schemas.android.com/apk/res/android"

Another way to accomplish the same task without needing to use a LinearLayout is to put a center-aligned "shim" in the middle of the parent layout, then align other elements to it. If you set the half-width element's width to match_parent, but align both their left and right sides, they'll end up shrinking themselves to fit.

<pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:paddingBottom="@dimen/activity_vertical_margin"
 android:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin"
 tools:context="com.example.EqualWidthExample" &gt;

 &lt;!-- An invisible view aligned to the center of the parent. Allows other
 views to be arranged on either side --&gt;
 &lt;View 
 android:id="@+id/centerShim"
 android:layout_height="match_parent"
 android:layout_width="0dp"
 android:visibility="invisible"
 android:layout_centerHorizontal="true"/&gt;

 &lt;!--Set width to match_parent sets maximum width. alignParentLeft aligns 
 the left edge of this view with the left edge of its parent. toLeftOf 
 sets the right edge of this view to align with the left edge of the 
 given view. The result of all three settings is that this view will 
 always take up exactly half of the width of its parent, however wide 
 that may be. --&gt;
 &lt;Button
 android:id="@+id/btLeft"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_alignParentLeft="true"
 android:layout_toLeftOf="@+id/centerShim"
 android:text="Left Button" /&gt;

 &lt;!--Same deal, but on the right --&gt;
 &lt;Button
 android:id="@+id/btRight"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_alignParentRight="true"
 android:layout_toRightOf="@+id/centerShim"
 android:layout_below="@+id/tvLeft"
 android:text="Right Button" /&gt;
&lt;/RelativeLayout&gt;
</code></pre>

I tried many times to draw 2 Relative layout aligned horizontally and divided in half screen.

<img src="https://i.stack.imgur.com/oCJp1.png" alt="enter image description here">

I design the image with paint to explain a bit better what i mean.

Any suggestion?

Android: 2 relative layout divided in half screen
