我正在开发一个Android应用程序。我需要找到用户。所以我想使用Google OpenStreetMap。我想将打开的街道视图集成到我的应用程序中,但是当应用程序启动时,不会加载地图。相反,我只得到一个标记。这是我的代码:
import org.osmdroid.views.MapView;
import org.osmdroid.views.overlay.MyLocationOverlay;
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
public class MainActivity extends Activity {
MyItemizedOverlay myItemizedOverlay = null;
MyLocationOverlay myLocationOverlay = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MapView mapView = (MapView) findViewById(R.id.button1);
mapView.setBuiltInZoomControls(true);
Drawable marker = getResources().getDrawable(
android.R.drawable.star_big_on);
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");
myLocationOverlay = new MyLocationOverlay(this, mapView);
mapView.getOverlays(`enter code here`).add(myLocationOverlay);
myLocationOverlay.enableMyLocation();
}
}
感谢您的帮助。

您没有设置磁贴源。请恰当地致电setTileSource()
对象上的MapView
。
请不要混淆条款,没有“谷歌开放街道地图”。该项目名为OpenStreetMap(最后没有 s ),谷歌根本不参与。
