Question

我的操作栏中有一点问题。我只能通过从左到右切换来看到我的抽屉，而当我点击汉堡菜单图标时我想看到它。这是xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v4.widget.DrawerLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/drawerLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#FFC100"
                android:text="bite"
                android:minHeight="?attr/actionBarSize" />



        </LinearLayout>

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="left">

            <include layout="@layout/drawer"/>

        </FrameLayout>

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

这是java：

public class HomeActivity extends AppCompatActivity {
    Toolbar toolbar;
    DrawerLayout drawerLayout;
    ActionBarDrawerToggle drawerToggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        this.toolbar = (Toolbar) findViewById(R.id.toolbar);

        setSupportActionBar(this.toolbar);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        this.drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
        this.drawerToggle = new ActionBarDrawerToggle(this,this.drawerLayout,0,0);
        this.drawerLayout.addDrawerListener(this.drawerToggle);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // synchroniser le drawerToggle après la restauration via onRestoreInstanceState
        drawerToggle.syncState();
    }
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        drawerToggle.onConfigurationChanged(newConfig);
    }
}

如果可能的话，我想保留这种代码结构。

谢谢！

我有一个类似的代码，工作正常，试试这个

<Application x:Class="TabItemBadgeLayout.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:TabItemBadgeLayout"
         StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

我认为你需要ActionBarDrawerToggle的另一个构造函数，一个带有工具栏参数的构造函数。

this.drawerToggle = new ActionBarDrawerToggle(this,this.drawerLayout,toolbar,0,0);
