supportmapfragment

问题 I am a beginner trying to use google maps, and I have followed the instructions given here: https://developers.google.com/maps/documentation/android-api/map?hl=zh-tw But I'm stuck at mapFragment.getMapAsync(this) and have been unable to find an answer. Here is the code: public class GoogleMapPage extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.googlemap); MapFragment mapFragment =

问题 When my SupportMapFragment onCreateView() method is called, I read the map's getProjection().getVisibleRegion().latLngBounds.northeast.x and getProjection().getVisibleRegion().latLngBounds.southwest.y The first time I launch the app (in portrait mode), I get x=720 and y=1230 . However, after changing the orientation to landscape I'm seeing the same values again. Going back to portrait mode yields x=1280 and y=670 (which is what I'd expect from landscape), and going back to landscape gives the

问题 I need to embed a SupportMapFragment in a Dialog . This is the best I could think of: public class SupportMapFragmentDialog extends DialogFragment { private final SupportMapFragment fragment; public SupportMapFragmentDialog() { fragment = new SupportMapFragment(); setTargetFragment(fragment, 1); } @Override public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) { return fragment.onCreateView(inflater, container, savedInstanceState);

问题 I'm trying to convert a google map activity to work inside a fragment that will be called in NavigationView. The map is showing but when i used the code getMapAsync mFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map); mFragment.getMapAsync(this); I got an error message E/AndroidRuntime: FATAL EXCEPTION: main E/AndroidRuntime: java.lang.NullPointerException E/AndroidRuntime: at com.sample.samplemap.samplemapFragment.onCreate(samplemapFragment.java:32) E

问题 All more or less works. But if the LocationFragment is recreated, the application falls. Manifest <?xml version="1.0" encoding="utf-8"?> <manifest package="XX.XX.XXXXXXXX" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-permission android:name="android.permission.GET_ACCOUNTS"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.CAMERA"/>

问题 I asked a question like this one the other day... this. I marked it as resolved, because the mistake was that isPlayServicesAvailable() returned false, because I had not the up to date Google Play Services. I have them now...but still NPE. The code: GoogleMap map; FragmentManager fmanager = getSupportFragmentManager(); Fragment fragment = fmanager.findFragmentById(R.id.map);//after this, fragment is null SupportMapFragment supportmapfragment = (SupportMapFragment)fragment; map

问题 I am wondering to know about how to get snapshot from SupportMapFragment. I have no idea. Please help. Thanks for your advance. 回答1: You can try to take a screen shot of the fragment View: View view = findViewById(R.id.fragmentId); view.setDrawingCacheEnabled(true); Bitmap bitmap = view.getDrawingCache(); BitmapDrawable bitmapDrawable = new BitmapDrawable(bitmap); I haven't tested it. 回答2: To get a drawable you can implement this code: SnapshotReadyCallback callback = new

问题 Background Suppose I have a view that works as the background (MapFragment in my case), and some other views that are the content of the activity. The problem Focusing an EditText, it shows the soft keyboard, causing all views to change their sizes, including the background view. This means that showing the soft keyboard causes the background to "jump" and re-layout itself. This is especially problematic in my case, as I use MapFragment as the background. That's because I can think of a
