问题描述
我收到此错误：
android.view.InflateException: Binary XML file line #13: Error inflating class com.google.android.maps.MapView
这是我的MapView类
here is my MapView class
public class MapViewActivity extends BaseFragment {
private TextView mTvTitle;
private View mView;
/*mapview members*/
private MapView mMapView;
private MapController mapController;
private LocationManager locationManager;
private MyLocationOverlay myLocationOverlay;
private static final int DEFAULT_ZOOM = 14;
private GeoUpdateHandler locationListener = new GeoUpdateHandler();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public void onResume() {
super.onResume();
myLocationOverlay.enableMyLocation();
myLocationOverlay.enableCompass();
}
@Override
public void onPause() {
super.onPause();
locationManager.removeUpdates(locationListener);
myLocationOverlay.disableMyLocation();
myLocationOverlay.disableCompass();
}
@Override
public void onDestroy() {
super.onDestroy();
myLocationOverlay.disableMyLocation();
myLocationOverlay.disableCompass();
}
@SuppressWarnings("unchecked")
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.map_activity, container, false);
mTvTitle = (TextView) mView.findViewById(R.id.tvTitle);
mTvTitle.setText(getResources().getString(R.string.top_tab_around));
mMapView = (MapView) mView.findViewById(R.id.mvMapAroundMe);
BindMap();
return mView;
}
private void BindMap() {
mMapView.preLoad();
mMapView.setBuiltInZoomControls(true);
mMapView.setSatellite(false);
mapController = mMapView.getController();
mapController.setZoom(14); // Zoom 1 is world view
locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
myLocationOverlay = new MyLocationOverlay(getActivity(), mMapView);
mMapView.getOverlays().add(myLocationOverlay);
Drawable drawable = this.getResources().getDrawable(R.drawable.pin);
List<Overlay> mapOverlays = mMapView.getOverlays();
MyItemizedOverlay itemizedoverlay = new MyItemizedOverlay(drawable, getActivity());
OverlayItem oItem = new OverlayItem(GeopointFactory(33.446886, -86.057426), "title", "title2");
itemizedoverlay.addOverlay(oItem);
mapOverlays.add(itemizedoverlay);
mapOverlays.add(itemizedoverlay);
myLocationOverlay.runOnFirstFix(new Runnable() {
public void run() {
animateToPlaceOnMap ( GeopointFactory(33.446886, -86.057426) );
}
});
}
public class GeoUpdateHandler implements LocationListener {
@Override
public void onLocationChanged(Location location) {
mapController.animateTo( GeopointFactory(location.getLatitude(), location.getLongitude()));
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}
private class MyItemizedOverlay extends ItemizedOverlay {
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
Context mContext;
public MyItemizedOverlay(Drawable marker) {
super(boundCenterBottom(marker));
}
public MyItemizedOverlay(Drawable marker, Context context) {
super(boundCenterBottom(marker));
mContext = context;
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size() {
return mOverlays.size();
}
@Override
protected boolean onTap(int index) {
final int tempIndex = index;
OverlayItem item = mOverlays.get(index);
AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
dialog.setTitle(item.getTitle());
dialog.setMessage(item.getSnippet());
dialog.setPositiveButton("פרטים",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
}
});
dialog.show();
return true;
}
}
private void animateToPlaceOnMap(final GeoPoint geopoint) {
mMapView.post(new Runnable() {
@Override
public void run() {
mMapView.invalidate();
mapController.animateTo(geopoint);
mapController.setZoom(DEFAULT_ZOOM);
}
});
}
private GeoPoint GeopointFactory(double latitude, double longitude) {
int lat = (int) (latitude * 1E6);
int lng = (int) (longitude * 1E6);
return new GeoPoint(lat, lng);
}
}
这是我的清单：

推荐答案
我觉得你不理解我。你不应该能够把图形页面的片段在你的方式。
I think you don't understand me. You should not be able to put MapView in Fragment in the way you do.
这不是通常使用简单的片段图形页面（前新MapFragments）。
有一个hack允许它，你可以读到这里 http://stackoverflow.com/a/8126287/1233021
但我认为这是更好，当你不需要做任何开销使用新MapFragments ......它们可自12 12。链接是previous消息。
It's not typically to use a MapView in simple Fragment (before new MapFragments). There is a hack which allows it, you could read about it here http://stackoverflow.com/a/8126287/1233021 BuT I think it's better to use new MapFragments when you don't need to do any overhead... They are available since the 12th of December. The link is in previous message.
BTW：有一个问题，但与其他错误 http://stackoverflow.com/a/9448871/1233021
BTW: There was a problem but with other error http://stackoverflow.com/a/9448871/1233021
