Question

我尝试使用自定义标记图标（位图和文本视图）为1800个项目创建地图。由于我的应用程序在创建一些标记后关闭，因此导致内存不足。我该怎么做？这是我的代码的一部分我的代码：谢谢大家！再见

public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE)


    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    mMap.getUiSettings().setZoomControlsEnabled(true);
    mMap.getUiSettings().setCompassEnabled(true);
    mMap.getUiSettings().setMyLocationButtonEnabled(true);
    mMap.getUiSettings().setRotateGesturesEnabled(true);
    mMap.getUiSettings().setScrollGesturesEnabled(true);
    mMap.getUiSettings().setTiltGesturesEnabled(true);
    mMap.getUiSettings().setZoomGesturesEnabled(true);
    mMap.setMyLocationEnabled(true);

    start();
}

public void start() {
    new BackgroundTask().execute();

}


private class BackgroundTask extends AsyncTask<Void, Integer, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        progress.setProgress(0);
        progress.setMessage("Loading");
        progress.show();
        cursor.moveToFirst();


    }

    @Override
    protected String doInBackground(Void... arg0) {
        try {

            if (cursor.moveToFirst())

            {
                do {

                    nome = cursor.getString(cursor.getColumnIndex(LocalDbManage.KEY_NOME));
                    lati = cursor.getString(cursor.getColumnIndex(LocalDbManage.KEY_LATI));
                    longi = cursor.getString(cursor.getColumnIndex(LocalDbManage.KEY_LONGI));
                    prezzo = "€ "+cursor.getString(cursor.getColumnIndex(LocalDbManage.KEY_PREZZO));
                    id = cursor.getString(cursor.getColumnIndex(LocalDbManage.KEY_CONTACTID));
                    final double latitude = Double.parseDouble(lati);
                    final double longitude = Double.parseDouble(longi);


                    iconFactory.setRotation(90);
                    iconFactory.setStyle(IconGenerator.STYLE_ORANGE);
                    addIcon(iconFactory, prezzo, new LatLng(latitude, longitude));



                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            final MarkerOptions markerOptions = new MarkerOptions().
                                    icon(BitmapDescriptorFactory.fromBitmap(iconFactory.makeIcon())).
                                    position(new LatLng(latitude, longitude)).
                                    anchor(iconFactory.getAnchorU(), iconFactory.getAnchorV());
                            mMap.addMarker(markerOptions);

                    }
                    });

                } while (cursor.moveToNext());
            } else

            {
                System.out.println("ERROR");  // viene eseguito l'else
            }

            Thread.sleep(1200);
        } catch (InterruptedException e) {
        }

        return "Lavoro Terminato!";
    }

    @Override
    protected void onProgressUpdate(Integer... values) {

    MarkerOptions markerOptions = new MarkerOptions().
            icon(BitmapDescriptorFactory.fromBitmap(iconFactory.makeIcon())).
