Question

这是我的activity_main.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:id="@+id/drawerlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:showIn="com.example.cortana.testing.activity.MainActivity">

    <android.support.design.widget.CoordinatorLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true" >

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/appbar"
            android:paddingTop="@dimen/appbar_padding_top"
            android:theme="@style/MyMaterialTheme">


            <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/Theme.AppCompat.Light.DarkActionBar"
                app:theme="@style/MyMaterialTheme"
                android:titleTextColor="@color/textColorPrimary"
                >

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

            <android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:tabTextColor="@color/textTabUnselected"
                app:tabMode="fixed"
                app:tabGravity="fill"
                app:theme="@style/MyMaterialTheme"
                app:tabSelectedTextColor="@color/textTabSelected">

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

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

        <android.support.v4.view.ViewPager
            android:id="@+id/viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"  >
        </android.support.v4.view.ViewPager>

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

    <fragment
        android:layout_width="@dimen/nav_drawer_width"
        android:layout_height="match_parent"
        android:id="@+id/fragment_navigation_drawer"
        android:layout_gravity="start"
        app:layout="@layout/fragment_navigation_drawer"
        tools:layout="@layout/fragment_navigation_drawer"
        android:name="com.example.cortana.testing.activity.FragmentDrawer">

    </fragment>

</android.support.v4.widget.DrawerLayout>

这是fragment_navigation_drawer.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white">


    <RelativeLayout
        android:id="@+id/nav_header_container"
        android:layout_width="match_parent"
        android:layout_height="190dp"
        android:layout_alignParentTop="true"
        android:background="@color/colorPrimary">

        <ImageView
            android:layout_width="70dp"
            android:layout_height="70dp"
            android:src="@drawable/ic_action_profile"
            android:scaleType="fitCenter"
            android:layout_centerInParent="true" />

    </RelativeLayout>


    <android.support.v7.widget.RecyclerView
        android:id="@+id/drawerList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/nav_header_container"
        android:layout_marginTop="15dp" />


</RelativeLayout>

现在，我需要一个系统，导航抽屉和tablayout都出现在同一个活动中。根据{{1}}，它们也应该如此。但目前的输出是： image_current_android_app

我在这里缺少什么，如何在屏幕上显示导航图标（汉堡包图标）。

编辑：

我已将解决方案应用到我的代码中。现在输出如下：。在菜单中，我需要将溢出图标的颜色设置为白色。我试过这个：

activity_main.xml

这没有帮助，其他可用的解决方案非常繁琐（包括添加一些java和xml）。有没有办法简单地做到这一点？

EDIT2：找到解决方案

只需将此行添加到styles.xml即可运行

<resources>

    <!-- Base application theme. -->

    <!--    
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    -->

    <style name="MyMaterialTheme" parent="MyMaterialTheme.Base"></style>

    <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:textColorPrimary">@color/textColorPrimary</item>
        <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
        <item name="android:actionOverflowButtonStyle">@style/Widget.ActionButton.Overflow</item>
    </style>

    <style name="DrawerArrowStyle" parent="@style/Widget.AppCompat.DrawerArrowToggle">
        <item name="spinBars">true</item>
        <item name="color">@android:color/white</item>
    </style>    
</resources>

Answer 1

在Activity。

中声明此内容

private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;

在onCreate方法

中

 Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
 mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerlayout);

 toolbar.setTitleTextColor(getResources().getColor(android.R.color.white));
    setSupportActionBar(toolbar);

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,toolbar ,  R.string.drawer_open, R.string.drawer_close) { 

        /** Called when a drawer has settled in a completely closed state. */ 
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            //getActionBar().setTitle(mTitle);
            //invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        } 

        /** Called when a drawer has settled in a completely open state. */ 
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            //getActionBar().setTitle(mDrawerTitle);
            //invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        } 
    }; 


    // Set the drawer toggle as the DrawerListener 
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    mDrawerToggle.syncState();

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true);

并确保您已关注import

import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.Toolbar;

如果您在Activity中编写此代码，屏幕上会显示hamburger icon。

我无法在屏幕上看到导航抽屉：android
