LinearLayout填充整个屏幕宽度

Question

我已经制作了一个可重复使用的视图，由一组按钮组成。

我试图让按钮填满屏幕的整个宽度，但它无法正常工作。下面是我的XML文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_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=".Navi" >

 <LinearLayout

   </LinearLayout>



</RelativeLayout>

以下是我用来导入视图的代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_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=".Observation" >

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginTop="108dp" />

    <include layout="@layout/navigation"
        android:layout_width="fill_parent"/>

</RelativeLayout>

您只提到android:layout_width="fill_parent"

你需要添加宽度和宽度达到这个效果的高度。

However, if you want to override layout attributes using the <include> tag, you must override both android:layout_height and android:layout_width in order for other layout attributes to take effect.

Check out

此外，您应该使用match_parent代替fill_parent

Check this one too

但是，您还没有提到您遇到的确切问题，但我仍然猜测如果您看到所包含布局的所有方面都留下了一些空间，那么代码中的以下内容可能就是问题，

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_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=".Navi" >

你正在给它填充。

机器人：paddingBottom来=＆＃34; @扪/ activity_vertical_margin＆＃34; 机器人：paddingLeft =＆＃34; @扪/ activity_horizo​​ntal_margin＆＃34; 机器人：paddingRight =＆＃34; @扪/ activity_horizo​​ntal_margin＆＃34; 机器人：paddingTop =＆＃34; @扪/ activity_vertical_margin＆＃34;

尝试从RelativeLayout标记

中删除这些行
