所以我有一个应用程序,它必须显示许多商店的位置,这取决于你选择哪一个。带有 mapView 的页面的 XML 布局是 ViewFlipper 的一部分,而具有地图布局的部分是:
<RelativeLayout
android:id="@+id/RelativeLayout3"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/back2"
android:gravity="left" >
<ImageButton
android:id="@+id/backLocation3"
android:layout_width="72dp"
android:layout_height="30dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:src="@drawable/btn_zuruck2" />
<ImageView
android:id="@+id/imageViewMap"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/backLocation3"
android:layout_marginTop="14dp"
android:src="@drawable/businesslounge" />
<RelativeLayout
android:id="@+id/mapPlaceHolderLayout"
android:layout_width="300dp"
android:layout_height="200dip"
android:layout_alignLeft="@+id/backLocation3"
android:layout_below="@+id/imageViewMap"
android:layout_marginTop="92dp" >
</RelativeLayout>
<TextView
android:id="@+id/mapLocation"
android:layout_width="240dp"
android:layout_height="40dp"
android:layout_alignLeft="@+id/mapPlaceHolderLayout"
android:layout_below="@+id/imageViewMap"
android:layout_marginTop="47dp"
android:text="@string/maplocation"
android:textSize="25dp"
android:textColor="@color/purple" />
<ImageButton
android:id="@+id/phonereserve"
android:layout_width="220dp"
android:layout_height="36dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="24dp"
android:src="@drawable/rezervephone" />
</RelativeLayout>
与地图视图相关的代码部分是:
public class StandorteFragment extends MapHostFragment {
public String text2;
private RelativeLayout mapPlaceHolderLayout;
public AQuery aQuery;
private MapView myMapView;
private GeoPoint geoPoint;
private MapController mc;
@Override
protected Class<? extends Activity> getActivityClass() {
return LocationMapActivity.class;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.location, container, false);
ViewFlipperStandorte = (ViewFlipper) v.findViewById(R.id.viewFlipperLocation);
geoPoint = new GeoPoint( (int) (48.949997* 1E6), (int) (22.140213 * 1E6));
mapPlaceHolderLayout = (RelativeLayout)v.findViewById(R.id.mapPlaceHolderLayout);
mapPlaceHolderLayout.addView(onCreateMapView());
// myMapView = (MapView) v.findViewById(R.id.mapPlaceHolderLayout);
// mc = myMapView.getController();
// mc.animateTo(geoPoint);
//
它可以工作,但在 mapView 中不显示任何内容。如果我不使用 myMapView 和动画 geoPoint 评论这 3 行,它会强制关闭。我需要做什么?
编辑:onCreateMapView:
public View onCreateMapView() {
Intent intent = new Intent(getActivity(), getActivityClass());
final Window w = getLocalActivityManager().startActivity(ACTIVITY_TAG,
intent);
final View wd = w != null ? w.getDecorView() : null;
if (wd != null) {
ViewParent parent = wd.getParent();
if (parent != null) {
ViewGroup v = (ViewGroup) parent;
v.removeView(wd);
}
wd.setVisibility(View.VISIBLE);
wd.setFocusableInTouchMode(true);
if (wd instanceof ViewGroup) {
((ViewGroup) wd)
.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
}
}
return wd;
}
