  1. POMapView in a listView item
    text
    copied!<p>I have an activity with a listView, where each item can be expanded when clicked, showing a mapView. If another item is clicked, the open item is closed. The activity extends MapActivity, and there is only one instance of mapview, which I remove and add to the items as needed like this:</p> <pre><code>private MapView getMapView() { if (mMapView == null) { LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); mMapView = (MapView) inflater.inflate(R.layout.club_map,null); } else { ((ViewGroup) mMapView.getParent()).removeView(mMapView); } return mMapView; } private void attachMap(View targetView,String siteID) { if (openInPrgrs) { return; } RelativeLayout relView = (RelativeLayout) targetView.findViewById(R.id.clubDetailsLayout); LinearLayout mapContainer = (LinearLayout) relView.findViewById(R.id.mapContainer); UtilFunctions.logIfDebug("MembershipsList","Attaching Map. siteID " + siteID + " childCount = " + mapContainer.getChildCount()); if (mapContainer.getChildCount() &gt; 0 ) { return; } MapView mapView = getMapView(); mapContainer.addView(mapView); } </code></pre> <p>It works fine most of the time, but when the screen turns off and back on, or the open item is scrolled off screen and back, the mapView disappears. I know this is because the view is being recycled by the listView. If I try to attach the map in getView() (if the view is in the open position):</p> <pre><code>public View getView(int position, View convertView, ViewGroup parent) { final View resultView = super.getView(position, convertView, parent); LayoutParams lp = resultView.getLayoutParams(); if (curOpenPos == position) { LinearLayout mapContainer = (LinearLayout) resultView.findViewById(R.id.mapContainer); lp.height = item_height_open; attachMap(resultView, siteID); } </code></pre> <p>} the map disappears when the item is fully expanded, but when the screen goes off and on it does appear. </p> <p>Anyone know why this happens, or what I can do to solve it?</p>
 

Querying!
