【问题描述】：
我正在使用 OpenStreetMap 创建一个简单的地图应用程序。我在 MapView 中打开了地图并在地图上添加了标记。所有这一切都很好。 现在当用户点击标记时，应该会弹出一个描述框，其中包含该地点的名称、描述和图像视图。
MainActivity：
public class MainActivity extends Activity {
MyItemizedOverlay myItemizedOverlay = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
Drawable marker=getResources().getDrawable(R.drawable.pin_for_map);
int markerWidth = marker.getIntrinsicWidth();
int markerHeight = marker.getIntrinsicHeight();
marker.setBounds(0, markerHeight, markerWidth, 0);
ResourceProxy resourceProxy = new DefaultResourceProxyImpl(getApplicationContext());
myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy);
mapView.getOverlays().add(myItemizedOverlay);
GeoPoint myPoint1 = new GeoPoint(0*1000000, 0*1000000);
myItemizedOverlay.addItem(myPoint1, "myPoint1", "myPoint1");
GeoPoint myPoint2 = new GeoPoint(50*1000000, 50*1000000);
myItemizedOverlay.addItem(myPoint2, "myPoint2", "myPoint2");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
MyItemizedOverlay 类：
public class MyItemizedOverlay extends ItemizedOverlay<OverlayItem> {
private ArrayList<OverlayItem> overlayItemList = new ArrayList<OverlayItem>();
public MyItemizedOverlay(Drawable pDefaultMarker,
ResourceProxy pResourceProxy) {
super(pDefaultMarker, pResourceProxy);
// TODO Auto-generated constructor stub
}
public void addItem(GeoPoint p, String title, String snippet){
OverlayItem newItem = new OverlayItem(title, snippet, p);
overlayItemList.add(newItem);
populate();
}
@Override
public boolean onSnapToItem(int arg0, int arg1, Point arg2, IMapView arg3) {
// TODO Auto-generated method stub
return false;
}
@Override
protected OverlayItem createItem(int arg0) {
// TODO Auto-generated method stub
return overlayItemList.get(arg0);
}
@Override
public int size() {
// TODO Auto-generated method stub
return overlayItemList.size();
}
}
activity_main.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="5dp"
android:text="@string/hello_world"
tools:context=".MainActivity" />
<org.osmdroid.views.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"/>
</RelativeLayout>
清单：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.openstreetmaptutorial"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.openstreetmaptutorial.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
请导入osmdroid-android-4.1.jar和slf4j-android-1.5.8.jar库并运行项目。
我已经推荐了this link。
我希望输出类似于：
请建议我如何制作如上所示的弹出窗口
