Tôi đang cố truy xuất đoạn Bản đồ của Google trong khi sử dụng Tab trong ActionBar. Khi tôi tải trang tab, bản đồ tải tốt, nhưng tôi muốn lấy đối tượng bản đồ để tôi có thể căn giữa đối tượng, thêm điểm đánh dấu, v.v.Lấy Google Map Fragment trong onCreateView bằng cách sử dụng tab ActionBar
Có cách nào để làm điều này và nếu có, để cho tôi thấy như thế nào?
Dưới đây là mã cho trang theo thẻ của tôi ...
Phương pháp cụ thể Tôi đang làm việc với là public static class Map extends Fragment
public class Page3Activity extends FragmentActivity implements ActionBar.TabListener {
final Context context = this;
static GoogleMap map;
static MapView mMapView;
DatabaseHandler db = new DatabaseHandler(context);
AppSectionsPagerAdapter mAppSectionsPagerAdapter;
ViewPager mViewPager;
@SuppressLint("NewApi")
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.page3);
// Create the adapter that will return a fragment for each of the three primary sections
// of the app.
mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(getSupportFragmentManager());
ColorDrawable colorDrawable = new ColorDrawable();
final ActionBar actionBar = getActionBar();
colorDrawable.setColor(0xff9ACC00);
actionBar.setBackgroundDrawable(colorDrawable);
actionBar.setTitle("Road Trip Calculator");
actionBar.setSubtitle("Trip Information");
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_SHOW_TITLE);
// Specify that the Home/Up button should not be enabled, since there is no hierarchical
// parent.
actionBar.setHomeButtonEnabled(false);
// Specify that we will be displaying tabs in the action bar.
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Set up the ViewPager, attaching the adapter and setting up a listener for when the
// user swipes between sections.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mAppSectionsPagerAdapter);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// When swiping between different app sections, select the corresponding tab.
// We can also use ActionBar.Tab#select() to do this if we have a reference to the
// Tab.
actionBar.setSelectedNavigationItem(position);
}
});
// For each of the sections in the app, add a tab to the action bar.
for (int i = 0; i < mAppSectionsPagerAdapter.getCount(); i++) {
// Create a tab with text corresponding to the page title defined by the adapter.
// Also specify this Activity object, which implements the TabListener interface, as the
// listener for when this tab is selected.
actionBar.addTab(
actionBar.newTab()
.setText(mAppSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
}
/*

@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
}
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
// When the given tab is selected, switch to the corresponding page in the ViewPager.
mViewPager.setCurrentItem(tab.getPosition());
}

return new Map();
case 1:
return new Directions();
case 2:
return new poiList();

i=i+1;
}
return null;
}

Đây là tập tin XML của tôi (maptab.xml) mà tôi có bản đồ của tôi đoạn trong ...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="@+id/map1"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"
/>
</LinearLayout>
SOLVED
public static class Map extends Fragment {
MapView mapView;
GoogleMap map;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.maptab, container, false);
// Gets the MapView from the XML layout and creates it
mapView = (MapView) v.findViewById(R.id.mapview);
mapView.onCreate(savedInstanceState);
// Gets to GoogleMap from the MapView and does initialization stuff
map = mapView.getMap();
//map.getUiSettings().setMyLocationButtonEnabled(false);
//map.setMyLocationEnabled(true);
map.addMarker(new MarkerOptions().position(new LatLng(50.167003,19.383262)));
// Needs to call MapsInitializer before doing any CameraUpdateFactory calls
try {
MapsInitializer.initialize(this.getActivity());
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
// Updates the location and zoom of the MapView
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10);
map.animateCamera(cameraUpdate);
return v;
}
@Override
public void onResume() {
mapView.onResume();
super.onResume();
}
@Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}
@Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();

Nó sẽ hữu ích hơn cho người khác nếu bạn đề cập rằng bạn thay thế SupportMapFragment của bạn trong maptab.xml bằng MapView. – tsil
