Question

我做错了什么？不显示地图。我添加了libs：osmdroid-android-5.1和slf4j-android-1.6.1-RC1。我用离线地图制作了.zip。

Activity.java：

import android.location.Criteria;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import org.osmdroid.api.IMapController;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapView;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import java.lang.String;

public class MapsActivity extends AppCompatActivity {
    private MapView mapView;
    private int MAP_DEFAULT_ZOOM = 15;
    private double MAP_DEFAULT_LATITUDE = 49.292192;
    private double MAP_DEFAULT_LONGITUDE = 19.959055;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        mapView = (MapView) this.findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true); 
        mapView.setMultiTouchControls(true);
        mapView.setClickable(true);
        mapView.setUseDataConnection(false);
        mapView.getController().setZoom(MAP_DEFAULT_ZOOM);
        mapView.getController().setCenter(new GeoPoint(MAP_DEFAULT_LATITUDE, MAP_DEFAULT_LONGITUDE));
        mapView.setTileSource(TileSourceFactory.MAPNIK);
    }
}

我的在线研究没有找到任何东西。

我正在使用Android Studio。

Answer 1

osmdroid的已知问题无法正确呈现android studio的预览模式。它只是一个Android工作室的东西，应该在5.6中修复。

此外，5.1现在已经很老了，您可能需要考虑使用新版本。
