为什么 android 工具栏高度被削减了？

Question

我是最新 android studio 的设计模式的新手，那个有 include tag.I 尝试调整文件，但最终工具栏被剪切。

第一个Activity

first_activity.xml

 <?xml version="1.0" encoding="utf-8"?>

 <LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_height="match_parent" android:layout_width="match_parent"
 android:orientation="vertical">

   <include layout="@layout/app_bar_main" android:layout_width="match_parent"
    android:layout_height="wrap_content" />

  <android.support.v4.widget.DrawerLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/drawer_layout"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:fitsSystemWindows="true"
 tools:openDrawer="start">

 <!-- Framelayout to display Fragments -->
 <FrameLayout
     android:id="@+id/frame_container"
     android:layout_width="match_parent"
     android:layout_height="match_parent" />

 <!-- Listview to display slider menu -->
 <ListView
     android:id="@+id/main_nav_drawer"
     android:layout_width="240dp"
     android:layout_height="match_parent"
     android:layout_gravity="start"
     android:choiceMode="singleChoice"
     android:divider="#888"
     android:dividerHeight="1dp"
     android:background="#fff"/>
     <!--android:listSelector="@drawable/list_selector"-->
      </android.support.v4.widget.DrawerLayout> </LinearLayout>

这是我的应用栏布局。

app_bar_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".Activities.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:theme="@style/AppTheme.AppBarOverlay">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay"/>

    </android.support.design.widget.AppBarLayout>


</android.support.design.widget.CoordinatorLayout>

Answer 1

这样更改您的工具栏XML：

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay"/>

请注意 minHeight 不允许更小的尺寸，wrap_content 高度现在允许更大的工具栏。

试试这个...

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize" />

    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        tools:openDrawer="start">

        <!-- Framelayout to display Fragments -->
        <FrameLayout
            android:id="@+id/frame_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <!-- Listview to display slider menu -->
        <ListView
            android:id="@+id/main_nav_drawer"
            android:layout_width="240dp"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:background="#fff"
            android:choiceMode="singleChoice"
            android:divider="#888"
            android:dividerHeight="1dp" />
        <!--android:listSelector="@drawable/list_selector"-->
    </android.support.v4.widget.DrawerLayout>
</LinearLayout>

Answer 3

更改您的 app_bar_main 布局如下 -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.bits.ketan.geocoding.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />


</LinearLayout>

Answer 4

I am new to the design pattern in latest android studio,the one with include tag.I tried tweaking the files but ended up with cut toolbar

我遇到了类似的问题，顺便说一下，它在真实设备上工作。

并且，尝试使用

<include layout="@layout/app_bar_main"
   android:layout_width="match_parent"
   android:layout_height="wrap_content" />

在你的 DrawerLayout 里面 Toolbar 在 AppBarLayout

里面

检查以下链接：

http://developer.android.com/training/implementing-navigation/nav-drawer.html#DrawerLayout

To add a navigation drawer, declare your user interface with a DrawerLayout object as the root view of your layout. Inside the DrawerLayout, add one view that contains the main content for the screen (your primary layout when the drawer is hidden) and another view that contains the contents of the navigation drawer.

并且，使用 NavigationView 而不是 ListView。

一个很好的例子：

http://developer.android.com/intl/es/reference/android/support/design/widget/NavigationView.html

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:id="@+id/drawer_layout"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fitsSystemWindows="true">

     <!-- Your contents -->

     <android.support.design.widget.NavigationView
         android:id="@+id/navigation"
         android:layout_width="wrap_content"
         android:layout_height="match_parent"
         android:layout_gravity="start"
         app:menu="@menu/my_navigation_items" />
 </android.support.v4.widget.DrawerLayout>

Answer 5

从您的主题中移除 fitSystemWindows 属性

<item name="android:fitsSystemWindows">true</item>

为什么 android 工具栏高度被削减了？

Why android toolbar height is cut?

android

toolbar

android-layout
