支持工具栏的自定义视图不使用全宽 [英] Support Toolbar's custom view not using full width

问题描述

我正在使用支持v7的工具栏。我添加了一个自定义视图，但自定义视图似乎不符合match_parent。它只会伸展到它看到的第一个图标。有人知道这个修复吗？还是工具栏不是要这样用？

我的代码：

 < FrameLayout xmlns：android =http：// schemas .android.com / apk / res / android
 xmlns：tools =http://schemas.android.com/tools
 xmlns：app =http://schemas.android.com / apk / res-auto
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：clipChildren =false
 tools：context =com .example.activities.ToolbarActivity
> 
 
< android.support.v7.widget.Toolbar 
 android：id =@ + id / toolbar
 android：layout_height =100dp
 android ：layout_width =match_parent
 android：minHeight =？attr / actionBarSize
 android：background =@ color / light_gray
 app：popupTheme =@ style / ThemeOverlay.AppCompat。 
 app：theme =@ style / ThemeOverlay.AppCompat.Dark.ActionBar
 android：gravity =bottom
 android：clipChildren =false
> 
 
< RelativeLayout 
 android：layout_width =match_parent
 android：layout_height =30dp
 android：background =@ color / green
> 
 
 
< / RelativeLayout> 
 
< /android.support.v7.widget.Toolbar> 
 
< / FrameLayout> 
  

解决方案

我在Simon的链接中取得了成功： / p>

 < RelativeLayout xmlns：android =http://schemas.android.com/apk/res/android
 xmlns：tools =http://schemas.android.com/tools
 xmlns：app =http://schemas.android.com/apk/res-auto
 android：layout_width =match_parent
 android：layout_height =match_parent
 android：clipChildren =false
工具：context =com.example.activities.ToolbarActivity> 
 
< android.support.v7.widget.Toolbar 
 android：id =@ + id / toolbar
 android：layout_height =100dp
 android ：layout_width =match_parent
 android：minHeight =？attr / actionBarSize
 android：background =@ color / light_gray
 app：popupTheme =@ style / ThemeOverlay.AppCompat。光
 app：theme =@ style / ThemeOverlay.AppCompat.Dark.ActionBar/> 
 
< RelativeLayout 
 android：layout_width =match_parent
 android：layout_height =30dp
 android：layout_marginTop =70dp
 android：背景= @色/绿色 > 
 
< / RelativeLayout> 
 
< / RelativeLayout> 
  

I'm using support v7's toolbar. I added a custom view, but the custom view doesn't seem to obey "match_parent". It would only stretch as far as the first icon it sees. Does anyone know a fix to this? Or is the toolbar not meant to be used this way?

My code:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipChildren="false"
    tools:context="com.example.activities.ToolbarActivity"
    >

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="100dp"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/light_gray"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:gravity="bottom"
        android:clipChildren="false"
        >

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="30dp"
            android:background="@color/green"
            >


        </RelativeLayout>

    </android.support.v7.widget.Toolbar>

</FrameLayout>

解决方案

I have succeed with the approach in Simon's link:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipChildren="false"
    tools:context="com.example.activities.ToolbarActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="100dp"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/light_gray"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="30dp"
        android:layout_marginTop="70dp"
        android:background="@color/green">

    </RelativeLayout>

</RelativeLayout>
