我已经在libs目录中添加了这个库 osmdroid jar文件。 slf4j jar文件。
我按照https://androidcookbook.com/Recipe.seam?recipeId=2521中的教程进行了操作 但地图没有显示,我不知道发生了什么
这是我的MainAcitvity.java
package com.example.pc_parinussa.osm;
import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;
import org.osmdroid.views.overlay.ScaleBarOverlay;
public class MainActivity extends Activity {
private MapView mMapView;
private MapController mMapController;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMapView = (MapView) findViewById(R.id.mapview);
mMapView.setTileSource(TileSourceFactory.MAPQUESTOSM);
mMapView.setBuiltInZoomControls(true);
mMapController = (MapController) mMapView.getController();
mMapController.setZoom(13);
GeoPoint gPt = new GeoPoint(51500000, -150000);
mMapController.setCenter(gPt);
}
}
我的activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

<org.osmdroid.views.MapView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/mapview">

看起来您没有设置您的用户代理。尝试通过以下方式进行设置:
Configuration.getInstance().setUserAgentValue(...)
e.g:
Configuration.getInstance().setUserAgentValue(getPackageName())

OSM需要访问手机的外部存储。
首先,在AndroidManifest中添加以下权限:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
第二,如果您的SDK版本晚于23,则用户必须手动允许该权限。然后也在您的活动中添加以下代码。最好在OSM活动之前启动此活动。否则,在第一次启动该应用程序时,您仍然看不到该地图-您只能在重新启动该应用程序时才能看到该地图。
注意:应该在“ setContentView(R.layout.your_layout_name);”之前写一些代码
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M)
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.WRITE_EXTERNAL_STORAGE},1);
}
setContentView(R.layout.your_layout_name);
第一次启动应用程序时,请参阅需要您允许的框图片:
