问题描述
我的MainActivity.xml如下:

此外，我的styles.xml是:

<活动android:name =.MainActivity"android:label ="BEEP"android:theme ="@ style/AppTheme.NoActionBar"><意图过滤器>< action android:name ="android.intent.action.MAIN"/>< category android:name ="android.intent.category.LAUNCHER"/></intent-filter></activity> 如果需要，这是MainActivity.java的相关部分:

当您将 Theme.AppCompat.Light.DarkActionBar 放入AndroidManifest的 Application 标记中时，所有活动将包含默认操作栏.
使用 NoActionBar 在您的styles.xml中再创建一个主题，并将其应用于您的 NavigationDrawerActivity .
即
< style name ="navigation_theme" parent ="Theme.AppCompat.Light.NoActionBar"/> 将其设置为您的导航活动
<活动android:name =.NavigationDrawerActivity"android:label ="@ string/title_activity_navigation_drawer"android:theme ="@ style/navigationtheme"/>
具有ActionBar的默认主题和具有NoActionBar主题的NavigationDrawerActivity的示例

正如@Talisman所说，这是TabLayout和ViewPager的问题DrawerLayout的
<?xml version ="1.0" encoding ="utf-8"?>< 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"工具:openDrawer ="start">< android.support.design.widget.CoordinatorLayoutandroid:layout_width ="match_parent"android:layout_height ="match_parent"工具:context ="com.and.NavigationDrawerActivity">< android.support.design.widget.AppBarLayoutandroid:layout_width ="match_parent"android:layout_height ="wrap_content"android:theme ="@ style/AppTheme.AppBarOverlay">< android.support.v7.widget.Toolbarandroid:id ="@ + id/toolbar"android:layout_width ="match_parent"android:layout_height =?attr/actionBarSize"android:background ="@ android:color/holo_blue_light"app:popupTheme ="@ style/AppTheme.PopupOverlay"/></android.support.design.widget.AppBarLayout><！-您在此FrameLayout中的内容->< FrameLayoutandroid:id ="@ + id/container"android:layout_width ="match_parent"android:layout_height ="match_parent"app:layout_behavior ="@ string/appbar_scrolling_view_behavior"工具:context ="com.and.NavigationDrawerActivity"></FrameLayout>< android.support.design.widget.FloatingActionButtonandroid:id ="@ + id/fab"android:layout_width ="wrap_content"android:layout_height ="wrap_content"android:layout_gravity ="bottom | end"android:layout_margin ="@ dimen/fab_margin"app:srcCompat ="@ android:drawable/ic_dialog_email"/></android.support.design.widget.CoordinatorLayout>< android.support.design.widget.NavigationViewandroid:id ="@ + id/nav_view"android:layout_width ="wrap_content"android:layout_height ="match_parent"android:layout_gravity ="start"android:fitsSystemWindows ="true"app:headerLayout ="@ layout/nav_header_navigation_drawer"app:menu ="@ menu/activity_navigation_drawer_drawer"/></android.support.v4.widget.DrawerLayout> 现在在其他片段中设置 TabLayout 和 ViewPager ，然后在 onCreate 方法的此 FrameLayout 中加载该片段 NavigationDrawerActivity
FragmentManager fm = getSupportFragmentManager();FragmentTransaction tr = fm.beginTransaction();tr.replace(R.id.frame_container，片段);tr.commitAllowingStateLoss(); ，其中fragment是另一个包含TabLayout和ViewPager的片段.
My MainActivity.xml is as below:
<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.TabItem

app:layout_behavior="@string/appbar_scrolling_view_behavior" >
</android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.DrawerLayout>
My intention is to have an appbar with navigation drawer (icon on left), and options menu (icon on right). However, it appears to be stuck underneath the system default. Here is an image showing its preview:
Additionally, my styles.xml is:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar" parent="AppTheme">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
Changing AppCompat.Light.DarkActionBar to NoActionBar has no effect. The appbar with "AppName" just remains above the other appbar (which should show "BEEP" as text, in addition to the two icons for navbar and options menu) - NoActionBar is also defined in the manifest for the activity:
<activity
android:name=".MainActivity"
android:label="BEEP"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Here is the relevant part of the MainActivity.java, if needed:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
...
So, how can I get the toolbar (ID is "toolbar") to display instead of the default appbar that currently contains the text "AppName" in the above image? I also followed this, however there is no change in the result.
EDIT 1: The following screenshot shows my user-defined appbar appearing underneath the default, for some reason. I have also included my app_bar_appbar.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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
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>
<include layout="@layout/content_appbar" />
</android.support.design.widget.CoordinatorLayout>
解决方案
As you are having Theme.AppCompat.Light.DarkActionBar to your Application tag of AndroidManifest all activity will include default actionbar.
Create one more theme in your styles.xml with NoActionBar and apply this to your NavigationDrawerActivity.
i.e.
<style name="navigation_theme" parent="Theme.AppCompat.Light.NoActionBar"/>
Set it to your Navigation Activity
<activity
android:name=".NavigationDrawerActivity"
android:label="@string/title_activity_navigation_drawer"
android:theme="@style/navigationtheme" />
Example of default theme with ActionBar and NavigationDrawerActivity with NoActionBar theme
EDIT
As @Talisman said, it was the issue with the TabLayout and ViewPager of DrawerLayout
<?xml version="1.0" encoding="utf-8"?>
<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">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.and.NavigationDrawerActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
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="@android:color/holo_blue_light"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!--Your content in this FrameLayout-->
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.and.NavigationDrawerActivity">
</FrameLayout>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
app:srcCompat="@android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_navigation_drawer"
app:menu="@menu/activity_navigation_drawer_drawer" />
</android.support.v4.widget.DrawerLayout>
Now Set the TabLayout and ViewPager in other Fragment and Load that fragment in this FrameLayout on onCreate method of NavigationDrawerActivity
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction tr = fm.beginTransaction();
tr.replace(R.id.frame_container, fragment);
tr.commitAllowingStateLoss();
where fragment is other fragment which contains your TabLayout and ViewPager.
