我使用的GoogleMap V2和我有一個GridView和MapView的那樣：黑屏時變焦在圖形頁面
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1" >
<com.google.android.gms.maps.MapView
android:id="@+id/map_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.5" />
<GridView
android:id="@+id/gv_all_pubs"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.5"
android:background="@color/BurlyWood"
android:columnWidth="300dp"
android:horizontalSpacing="5dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="3dp" />
</LinearLayout>
</FrameLayout>
的代碼是：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = null;
try
{
view = inflater.inflate(R.layout.all_pubs_layout, container, false);
mapView = (MapView)view.findViewById(R.id.map_view);
mapView.onCreate(savedInstanceState);
map = mapView.getMap();
//set the map options
map.setMyLocationEnabled(false);
map.getUiSettings().setMyLocationButtonEnabled(false);
map.getUiSettings().setZoomControlsEnabled(true);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
map.getUiSettings().setCompassEnabled(true);
try
{
MapsInitializer.initialize(mContext);
}
catch (Exception e){}
gvAllPubs = (GridView)view.findViewById(R.id.gv_all_pubs);
gvAdapter = new AllPubsGridViewAdapter(mContext, App.pubSortedByLastUpdate);
gvAllPubs.setAdapter(gvAdapter);
gvAllPubs.setOnItemClickListener(gridViewClickListener);
//select the first item in the list
try
{
gvAllPubs.setSelection(lastPubSelected);
drawLastPubSelected(lastPubSelected);
}
catch (Exception e) {}
}
catch(Exception e){}
return view;
}
和GridView的項目點擊傾聽者是：
OnItemClickListener gridViewClickListener = new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long id)
{
lastPubSelected = position;
drawLastPubSelected(lastPubSelected);
}
};
private void drawLastPubSelected(int position)
{
//get the selected pub
PubObj selectedPub = App.pubSortedByLastUpdate.get(position);
double pubLat = selectedPub.pubLatitude;
double pubLong = selectedPub.pubLongtitude;
//get the pub location
LatLng pubLocation = new LatLng(pubLat, pubLong);
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(pubLocation, 15);
//zoom the map to the pub
map.animateCamera(cameraUpdate);
//create the marker at the pub location
MarkerOptions mapMarkerOption = new MarkerOptions();
mapMarkerOption.position(pubLocation);
mapMarkerOption.title(selectedPub.pubName.toString() +" - "+selectedPub.pubAddress.toString());
mapMarkerOption.snippet(selectedPub.pubCurrentStatus.toString());
mapMarkerOption.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_VIOLET));
mapMarkerOption.draggable(false);
map.clear();
Marker marker = map.addMarker(mapMarkerOption);
marker.showInfoWindow();
//on marker click open pub details activity
map.setOnInfoWindowClickListener(new OnInfoWindowClickListener()
{
@Override
public void onInfoWindowClick(Marker marker)
{
//open pub details activity
Log.d("pubs", "a");
}
});
}
現在我有兩個設備，我調試，第一個是三星galaxy s2與android版本4.1.2和另一個是與Android版本4.2.2, nexus 4問題是，當我放大我的nexus 4我看到一個空白屏幕（灰色方塊，我只能看到縮放按鈕），並在上我的sgs2我可以放大和縮小沒有問題，我看到一切都完美。
可能是什麼問題？ 現在，我正在爲這個問題苦苦掙扎一段時間。 預先感謝所有能夠幫助的人。
Best， Shalom Melamed。
