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:
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
<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>
