Question

我正在尝试使用导航抽屉创建一个操作栏（通过工具栏），但是我只设法让导航抽屉部件工作。当应用程序在模拟器中加载时，似乎工具栏在屏幕上显示的时间只有几分之一秒才消失，显示没有工具栏的屏幕。如何让工具栏显示/不会在加载时消失？

这就是它的样子：

styles.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">

<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorPrimaryDark</item>
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

</style>
<style name="AppTheme.NoActionBar">
    <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>

styles.xml（v21）

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

<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- API 14 theme customizations can go here. -->
    <item name="android:statusBarColor">@color/colorPrimaryDark</item>
    <item name="colorPrimary">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorPrimaryDark</item>
</style>
<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>

</style>
</resources>

MainActivity.java（修剪过多的代码）

import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

public class MainActivity extends AppCompatActivity implements OnMarkerClickListener {
Toolbar toolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_layout);
 toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

...
}

DrawerLayout只应包含两个子视图，首先是主要内容，然后是抽屉视图。

Creating a Navigation Drawer

Answer 2

正如Ajay所说，DrawerLayout应该只包含两个布局，所以我正在编辑你的一些代码以满足要求，我认为这样做只是试一试

main_layout.xml

<?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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
<include
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    layout="@layout/other_layout"/>
<android.support.design.widget.NavigationView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/navigation_view"
    android:layout_gravity="start"
    app:menu="@menu/drawer_menu"/>
</android.support.v4.widget.DrawerLayout>

现在将您的其他布局添加到另一个布局文件

other_layout.xml

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/toolbar"
    android:background="?attr/colorPrimaryDark"
    android:minHeight="?attr/actionBarSize"
    android:fitsSystemWindows="true"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<FrameLayout
    android:id="@+id/mainfrag"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:layout="@layout/main_layout" />
</FrameLayout>
</LinearLayout>

工具栏无法显示（在消失前短暂显示）
