我已经好几周都在寻找答案,所以请原谅我是否有点沮丧。这是因为我。
提前,对不起,如果之前已经问过这个问题。我是Android编程的新手(我主要做网络应用程序),这对我来说是一个全新的世界。感谢所有帮助!
我想要做的是将导航抽屉添加到磨坊地图活动的标准运行中。我该怎么做呢?我希望每个按钮都能将地图重新定位到另一个地方。
当我们参与其中时,我计划在地图中创建一个KML图层。如您所知,KML点内置了信息,因此当您点击/点击它们时,您可以看到信息。我想让KML点打开导航抽屉及其内置信息。我很好地使用默认的Android点,但是KML的东西是值得赞赏的。如果您想要一个参考框架,请考虑类似这个JavaScript示例,但大多数情况下隐藏侧边栏:https://developers.google.com/maps/documentation/javascript/kml
MainActivity.java:
package us.tourismproject.jared.tourismprojectandroid;
import android.content.res.Resources;
import android.nfc.Tag;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MapStyleOptions;
import com.google.android.gms.maps.model.MarkerOptions;
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
private static final String TAG = MainActivity.class.getSimpleName();
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.
*/
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
try {
// Customise the styling of the base map using a JSON object defined
// in a raw resource file.
boolean success = googleMap.setMapStyle(
MapStyleOptions.loadRawResourceStyle(
this, R.raw.style_json));
if (!success) {
Log.e(TAG, "Style parsing failed.");
}
} catch (Resources.NotFoundException e) {
Log.e(TAG, "Can't find style. Error: ", e);
}
// Position the map's camera near Sydney, Australia.
googleMap.moveCamera(CameraUpdateFactory.newLatLng(new LatLng(-34, 151)));
}
}
activity_main.xml中
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="us.tourismproject.jared.tourismprojectandroid.MainActivity" />
提前感谢您的帮助。美好的一天吧!

首先,您需要将Fragment
包含在另一个包含Navigation drawer
的父布局中,然后在java中为drawer
设置内容。
请参阅this
来到交互部分,KML
只是一个符号,它包含一些信息,您可以做的是为每个KML地理点创建一个marker
并将其绑定到{{的点击函数1}}打开marker
。
Check here用于将标记添加到Google地图

如果您希望导航抽屉覆盖地图活动而不是更新 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/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent"
android:fitsSystemWindows="true" tools:openDrawer="start">
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="us.tourismproject.jared.tourismprojectandroid.MainActivity" />
<android.support.design.widget.NavigationView android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- Draw your view whatever you want to draw -->
</LinearLayout>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
它将创建您的导航抽屉作为rajan提及的一个答案,您需要编写一些代码来处理导航抽屉。
