Question

My app uses HoneyComb fragments where my left side panel has listview and right side panel has a MapView with some TextViews.Initially i wrote map view in the map_fragment_right_side.xml which resulted in freezing the screen for long time ,so I decided to inflate the map view at runtime in an AsyncTask in vain .The code goes like this

class LoadMapTask extends AsyncTask<String, Void, Boolean>
{

    MapView inflatedMapView = null;

    @Override
    protected void onPreExecute() {

        progressbar.setVisibility( View.VISIBLE );

    }


    @Override
    protected Boolean doInBackground(String... params)
    {


        try{

        inflatedMapView = new MapView(getActivity(),getActivity().getResources().getString(R.string.mapkey));

        addMapViewhere.addView(inflatedMapView);


        inflatedMapView.getController().setCenter(getPoint(Double.valueOf(latitude),Double.valueOf(longitude)));

        inflatedMapView.getController().setZoom(17);

        inflatedMapView.setBuiltInZoomControls(true);

        sites=new SitesOverlay();

        inflatedMapView.getOverlays().clear();

        inflatedMapView.getOverlays().add(sites);

        }catch (Exception e) {
         e.printStackTrace();
        }


        return true;

    }

    @Override
    protected void onPostExecute(Boolean res)
    {
        if( progressbar != null )
        {
            progressbar.setVisibility( View.GONE );
        }






    }

}

I doubt whether its possible to inflate map view from non-UI thread .I will be glad if someone suggest me the right way to do this.I don’t want the screen to freeze until map gets loaded.
thanks,

Answer 1

Inflate it from onPreExecute() or in onPostExecute()
