I have this RelativeLayout component and I want to set it to the entire screen width. How can I do that?

我有这个RelativeLayout组件,我想将其设置为整个屏幕宽度。我怎样才能做到这一点?

atendente.xml

<?xml version="1.0" encoding="utf-8"?>
<merge
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

<RelativeLayout
    style="@style/layoutAtendenteBalao"
    android:id="@+atendente/rltAtendenteBalao">

styles.xml

<style name="layoutAtendenteBalao">
     <item name="android:layout_width">fill_parent</item>
     <item name="android:layout_height">210px</item>
     <item name="android:layout_alignParentRight">true</item>

You should set it when you including this layout to other, like this:

将此布局包含到其他布局时应该设置它,如下所示:

<include android:id=”@+id/your_id”
         android:layout_width=”match_parent”
         android:layout_height=”match_parent”
         layout=”@layout/your_layout”/>

#2

For this to work, you have to add android:layout_width , and android:layout_height in your layout node like:

为此,您必须在布局节点中添加android:layout_width和android:layout_height,如:

<RelativeLayout
    style="@style/layoutAtendenteBalao"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+atendente/rltAtendenteBalao">

use -1 and -2 for fill_parrent and wrap_content

使用-1和-2表示fill_parrent和wrap_content

Reference: http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html#FILL_PARENT

<style name="layoutAtendenteBalao">
     <item name="android:layout_width">-1</item>
     <item name="android:layout_height">210px</item>
     <item name="android:layout_alignParentRight">true</item>
     <item name="android:layout_alignParentBottom">true</item>
     <item name="android:layout_marginRight">176px</item>
     <item name="android:layout_marginBottom">140px</item>
     <item name="android:background">@drawable/borda_balao</item>
     <item name="android:paddingLeft">15dp</item>
     <item name="android:paddingRight">15dp</item>
     <item name="android:paddingTop">10dp</item>
     <item name="android:paddingBottom">10dp</item>
</style>
