我有一个带导航抽屉的启动器活动。当我将地图添加到该启动器活动时,我没有看到任何工具栏,所以我无法控制导航抽屉。这是我的活动现在的样子: enter image description here

这里应该是什么样的(我需要这个工具栏) enter image description here

导航抽屉应与此enter image description here

重叠

所以这是我的代码

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map_nav);

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

    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.setDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    mapView = new MapView(this);

    MapHandler.getMapHandler().init(this, mapView);

    addMarkers();
}

如您所见,我将工具栏添加到活动

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

这是MapHandler init方法()

的一部分
mapView.getLayerManager().getLayers().add(tileRendererLayer);
    ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    activity.addContentView(mapView, params);

这是清单文件中的代码

    <activity
        android:name=".map.MapNavActivity"
        android:theme="@style/AppTheme.NoActionBar"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

那么我做错了什么?

编辑我的导航活动xml

我用Majestic的帮助解决了这个问题。谢谢!我在content_map_nav.xml

中添加了此代码
<org.mapsforge.map.android.view.MapView
    android:id="@+id/mapView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    xmlns:android="http://schemas.android.com/apk/res/android">
</org.mapsforge.map.android.view.MapView>

并且在mainactivity中而不是mapView = new MapView()我写了这个mapView = (MapView) findViewById(R.id.mapView);,现在它可以了!

可能你已经在content_main.xml中用RelativeLayout或LinearLayout替换了ConstraintLayout,如果你想使用你应该保留的LinearLayout或RelativeLayout,你可以像这样包装你的布局:

  <?xml version="1.0" encoding="utf-8"?>
 <android.support.constraint.ConstraintLayout 
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"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.gmail.farhadkargaran.myapplication.MainActivity"
tools:showIn="@layout/app_bar_main">

<LinearLayout

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/main_bg"
    android:orientation="vertical"
    android:gravity="center"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    tools:showIn="@layout/app_bar_main">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</LinearLayout>
