我有一个数据列表视图，每个项目都会打开一个嵌入地图的视图。这张地图的目的是显示一个单一标记。代码运行良好，但如果我有很多列表项（50+），来回滑动会导致应用程序抛出OutOfMemory异常。
有人能帮助我理解我在这里做错了什么吗？我猜想我的地图初始化逻辑有问题，导致这种情况发生。现在我正在尝试找出其中的问题。
public class DetailView extends Fragment implements OnInfoWindowClickListener {
private MapView mMapView;
private GoogleMap googleMap;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mMapView = (MapView) v.findViewById(R.id.mapBusinessLocation);
mMapView.onCreate(savedInstanceState);
mMapView.onResume();//needed to get the map to display immediately
MapsInitializer.initialize(this.getActivity() );
//MapController myMapController = mMapView.getController();
googleMap = mMapView.getMap();
googleMap.setMyLocationEnabled(true);
CameraUpdate center=
CameraUpdateFactory.newLatLng(new LatLng(-20.269927,57.672729));
CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);
googleMap.moveCamera(center);
googleMap.animateCamera(zoom);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
placeMarker("test");
}
private Marker placeMarker(String title) {
//Get the hue
String pinColor = "#f29217";
int c = Color.parseColor(pinColor);
float[] pixelHSV = new float[3];
Color.colorToHSV(c, pixelHSV);
return googleMap.addMarker(new MarkerOptions()
.position(new LatLng(-20.269927,57.672729 ))
.title(title)
.snippet("")
.icon(BitmapDescriptorFactory.defaultMarker(pixelHSV[0])));
}
@Override
public void onResume() {
super.onResume();
if(mMapView != null) {
mMapView.onResume();
}
}
@Override
public void onPause() {
super.onPause();
if(mMapView != null) {
mMapView.onPause();
}
}
@Override
public void onDestroy() {
super.onDestroy();
if(mMapView != null) {
mMapView.onDestroy();
}
}
@Override
public void onLowMemory() {
super.onLowMemory();
if(mMapView != null) {
mMapView.onLowMemory();
}
}
}
当应用程序崩溃时，会给出以下堆栈跟踪信息...
