Android用Googleマップのフォーラムとチュートリアルをいくつか見た後、私はこれを持っています
public class MapsActivity extends MapActivity {
MapView mapView;
MapController mc;
GeoPoint p;
class MapOverlay extends com.google.android.maps.Overlay{
@Override
public boolean draw(Canvas canvas, MapView mapView,
boolean shadow, long when){
super.draw(canvas, mapView,shadow);
Point screenPts = new Point();
mapView.getProjection().toPixels(p,screenPts);
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);
return true;
}
public boolean onTouchEvent(MotionEvent event, MapView mapView){
if(event.getAction()==1) {
p=mapView.getProjection().fromPixels((int) event.getX(),(int) event.getY());
Toast.makeText(getBaseContext(),
p.getLatitudeE6()/1E6 + ","+p.getLongitudeE6()/1E6,
Toast.LENGTH_SHORT).show();
mc.animateTo(p);
return false;
} else return false;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
mapView=(MapView) findViewById(R.id.mapView);
LinearLayout zoomLayout=(LinearLayout)findViewById(R.id.zoom);
@SuppressWarnings("deprecation")
View zoomView=mapView.getZoomControls();
zoomLayout.addView(zoomView, new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
mapView.displayZoomControls(true);
mc=mapView.getController();
String coordinates[]={"51.986367","5.666304"};
double lat=Double.parseDouble(coordinates[0]);
double lng=Double.parseDouble(coordinates[1]);
p=new GeoPoint((int)(lat*1E6),(int)(lng*1E6));
mc.animateTo(p);
mc.setZoom(18);
MyLocationOverlay mMyLocationOverlay=new MyLocationOverlay(this,mapView);
mMyLocationOverlay.enableMyLocation();
mapView.getOverlays().add(mMyLocationOverlay);
mapView.invalidate();
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
Google 開発者によると、マニフェストを次のように変更しました。
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyAYLFPye3YL3HgXnPHGuoDCgYjrGJ4VtkA"/>

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
また、レイアウトに API キーを追加します
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="AIzaSyAYLFPye3YL3HgXnPHGuoDCgYjrGJ4VtkA"
android:clickable="true"
android:enabled="true"
class="com.google.android.gms.maps.MapFragment"/>
実行しますが、マップが画面に表示されません。何か提案はありますか?
