在Android上创建离线地图

Question

我是Android应用程序开发的新手,我必须创建一个离线地图Android应用程序.

我使用Mobile Atlas Creator获取地图视图osmdroid .zip格式,我不知道如何在我的应用程序中添加它.

有人可以告诉我如何在我的应用程序中使用Osmdroid吗？如果您能提供逐步说明,我将不胜感激.

Answer 1

这是我不久前制作的 Osmdroid 的绝对最小示例项目。

package osmdemo.demo;

import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

import android.app.Activity;
import android.os.Bundle;

// This is all you need to display an OSM map using osmdroid
public class OsmdroidDemoMap extends Activity {

    private MapView         mMapView;
    private MapController   mMapController;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.osm_main);
        mMapView = (MapView) findViewById(R.id.mapview);
        mMapView.setTileSource(TileSourceFactory.MAPNIK);
        mMapView.setBuiltInZoomControls(true);
        mMapController = mMapView.getController();
        mMapController.setZoom(13);
        GeoPoint gPt = new GeoPoint(51500000, -150000);
        //Centre map near to Hyde Park Corner, London
        mMapController.setCenter(gPt);
    }
}

把这个放在你的osm_main.xml

package osmdemo.demo;

import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

import android.app.Activity;
import android.os.Bundle;

// This is all you need to display an OSM map using osmdroid
public class OsmdroidDemoMap extends Activity {

    private MapView         mMapView;
    private MapController   mMapController;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.osm_main);
        mMapView = (MapView) findViewById(R.id.mapview);
        mMapView.setTileSource(TileSourceFactory.MAPNIK);
        mMapView.setBuiltInZoomControls(true);
        mMapController = mMapView.getController();
        mMapController.setZoom(13);
        GeoPoint gPt = new GeoPoint(51500000, -150000);
        //Centre map near to Hyde Park Corner, London
        mMapController.setCenter(gPt);
    }
}

slf4j-android-1.5.8.jar将和包含osmdroid-android-3.0.5.jar在构建路径中。（谷歌搜索从哪里获取）
