Android-Dismissing a dialog fragment

Android-Dismissing a dialog fragment - android

I have an activity which includes an imageview.
When I click on that image,a dialog fragment is shown consisting of html content and a button.
When I click on that button, I want to close this dialog fragment.
I tried to use function dismiss() but it was useless, the dialog fragment does not close, it refreshes actually, and sometimes closes after 3-4 touches on the button!.
Here's my code for the activity:
public class MainActivity extends FragmentActivity implements OnMapReadyCallback,GeneralCallback {
private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
private Polyline line;
private GoogleMap googleMap;
private Controller controller;
private JSONObject UserDetails;
private JSONArray routePath;
private JSONArray stopPoints;
private List<LatLng> pointsRoutePath;
private List<LatLng> pointsStopPoints;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
controller=new Controller(this);
requireLocationPermissions();
initializeGoogleMap();
configureImage();
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String permissions[], #NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initialize the map with both permissions
perms.put(android.Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(android.Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
// Fill with actual results from user
if (grantResults.length > 0) {
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
}
}
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
setZoomedLocation(googleMap);
controller.getUserDetails();
this.googleMap=googleMap;
}
//This function is used to require location permissions from the user during run time.
private void requireLocationPermissions(){

}
//This function is used to initialize Google Map Fragment
private void initializeGoogleMap(){

mapFragment.getMapAsync(this);
}

}

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.marker_hi);

AboutUs aboutUsFragment = new AboutUs();
// Show DialogFragment
aboutUsFragment.show(getSupportFragmentManager(), "AboutUs");
controller.aboutUS();
return true;
}
});
}
}
and here's my code for the dialog fragment:
public class AboutUs extends DialogFragment{
Controller controller;
private View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.about_us, container, false);
controller = new Controller(getActivity());
configureBackButton();
return view;
}
private void configureBackButton(){
Button backButton=view.findViewById(R.id.backButton);
backButton.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Log.i("onTouch","onTouch");
getDialog().dismiss();
return true;
}
});
}
public void initializeContent(JSONObject response){
try {
String content=response.getJSONArray("InnerData").getJSONObject(0).getString("content");
WebView webView = view.findViewById(R.id.html);
webView.loadDataWithBaseURL(null, content, "text/html", "utf-8", null);
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
public void onResume() {
super.onResume();
controller.aboutUS();
}
#Override
public void onDismiss(DialogInterface frag) {
dismissAllowingStateLoss();
// DO Something
}
}
Here's about_us.xml
<?xml version="1.0" encoding="utf-8"?>

Replace the onTouchListener in your backButton with an onClickListener.
backButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
getDialog().dismiss();
}
});
Click listeners are the recommended approach for buttons. Hopefully, this would make the behaviour of the button and the dialog fragment more predictable and deterministic.

Android Google Map KMZ/KML Loading Really Slow

I need to loads some KMZ/KML (I tryed both) in my Google Map MapView instance.
But they load really slow, they are 8 KMZ of around 300KB each and for each one it takes more than 3/4 seconds to get loaded.
How can I solve this?
Surfing in search of a solution I found they suggest to use the V3 version because it fix a polyline creation cycle really time consuming in V2.
This is the library:
implementation 'com.google.maps.android:android-maps-utils-v3:1.3.1'
The problem is that when I use this library the constructors of KmlLayer stop working because inside the class KmlLayer it doesn't found the following package of the GoogleMap class, so because all the constructors require a GoogleMap instance they stop working:
import com.google.android.libraries.maps.GoogleMap;
How can I solve this? Is using the V3 version a solution to my problem? If no how can I solve this?
I found other people having the same problem but when they load KML of 10MB or more and not of just 300KB...

The app does not crash on runtime, it only displays the map without the RecyclerView. In my gradle file i inlcuded the dependencies i needed. I tried messing around with the gradle file, nothing seems to work. In my logcat I have the following java.io.FileNotFoundException-No such file or directory.

Problem in library de.hdodenhof.circleimageview.CircleImageView. check this
https://github.com/hdodenhof/CircleImageView/issues/121
If you need to circle imageview you can use glide transformation with imageview
https://bumptech.github.io/glide/doc/transformations.html
Example glide v4:
RequestOptions options = new RequestOptions();
options.CircleCrop();
Glide.with(fragment)
.load(url)
.apply(options)
.into(imageView);

Unable to put button along with the google map

So, basically i was trying to put a button on top of my map fragment but it doesn't seems to work despite the map working completely fine. Even after extensively searching Google, I couldn't find an executable answer.

Google maps for android - markers not showing

I'm creating a MapFragment in android; maps is showing just fine (although it takes 10 seconds to open), but no marker is shown.
This is the code of the fragment:
public class VehiclesMapFragment extends MapFragment implements OnMapReadyCallback {
GoogleMap _map;
private void setUpMapIfNeeded() {
if (_map == null) {
_map = this.getMap();
//_map = this.getMap();
//if (_map != null) {
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
ReDrawList(_vehicles);
}
}, 2000);
//}
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
_map = googleMap;
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
ReDrawList(_vehicles);
}
}, 10000);
}
public VehiclesMapFragment() {
}
VehiclesPosition[] _vehicles = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
_vehicles = (VehiclesPosition[])getArguments().getSerializable("VEHICLES");
//setUpMapIfNeeded();
}
public void ReDrawList(VehiclesPosition[] vehicles)
{
if (vehicles != null && vehicles.length > 0 && _map != null) {
LatLngBounds bounds = null;
for (VehiclesPosition vp : vehicles) {
LatLng latlngPos = vp.GetMapLatLng();
if (bounds == null)
bounds = new LatLngBounds(latlngPos, latlngPos);
else
bounds = bounds.including(latlngPos);
MarkerOptions mi = vp.GetMapMarker();
Marker mm = _map.addMarker(mi);
mm.showInfoWindow();
}
try{
_map.animateCamera(CameraUpdateFactory.zoomTo(12));
_map.animateCamera(CameraUpdateFactory.newLatLngBounds(bounds,100));
}catch (Exception exx) {
}
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View v = inflater.inflate(R.layout.fragment_vehicles_map, container, false);
setUpMapIfNeeded();
return v;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
//setUpMapIfNeeded();
try {
mListener = (OnFragmentInteractionListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()+ " must implement OnFragmentInteractionListener");
}
}
#Override
public void onDetach() {
super.onDetach();
mListener = null;
}
#Override
public void onResume() {
super.onResume();
}
private OnFragmentInteractionListener mListener;
public interface OnFragmentInteractionListener {
public void onFragmentInteraction(Uri uri);
}
}
and this is the layout file:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/map"
tools:context=".MapsActivity"
android:name="com.google.android.gms.maps.SupportMapFragment" />
and the fragment is instantiated by an activity, with:
Bundle args = new Bundle();
args.putSerializable("VEHICLES",_VehiclesList);
fragment_units_map = new VehiclesMapFragment();
_fragment_units_map.setArguments(args);
calling _map.animateCamera produce an exception at every call:
java.lang.IllegalStateException: Error using newLatLngBounds(LatLngBounds, int): Map size can't be 0. Most likely, layout has not yet occured for the map view. Either wait until layout has occurred or use newLatLngBounds(LatLngBounds, int, int, int) which allows you to specify the map's dimensions.

How can I handle map move end using Google Maps for Android V2?

I want to geocode address as soon as map center has been changed.
How can I handle map moveend with new Google Maps for Android V2? (I'm talking about the case then user drags map by finger)

Check out new maps api.
#Override
public void onMapReady(GoogleMap map) {
mMap = map;
mMap.setOnCameraIdleListener(this);
mMap.setOnCameraMoveStartedListener(this);
mMap.setOnCameraMoveListener(this);
mMap.setOnCameraMoveCanceledListener(this);
// Show Sydney on the map.
mMap.moveCamera(CameraUpdateFactory
.newLatLngZoom(new LatLng(-33.87365, 151.20689), 10));
}
#Override
public void onCameraMoveStarted(int reason) {
if (reason == OnCameraMoveStartedListener.REASON_GESTURE) {
Toast.makeText(this, "The user gestured on the map.",
Toast.LENGTH_SHORT).show();
} else if (reason == OnCameraMoveStartedListener
.REASON_API_ANIMATION) {
Toast.makeText(this, "The user tapped something on the map.",
Toast.LENGTH_SHORT).show();
} else if (reason == OnCameraMoveStartedListener
.REASON_DEVELOPER_ANIMATION) {
Toast.makeText(this, "The app moved the camera.",
Toast.LENGTH_SHORT).show();
}
}
#Override
public void onCameraMove() {
Toast.makeText(this, "The camera is moving.",
Toast.LENGTH_SHORT).show();
}
#Override
public void onCameraMoveCanceled() {
Toast.makeText(this, "Camera movement canceled.",
Toast.LENGTH_SHORT).show();
}
#Override
public void onCameraIdle() {
Toast.makeText(this, "The camera has stopped moving.",
Toast.LENGTH_SHORT).show();
}

Here is a possible workaround for determining drag start and drag end events:
You have to extend SupportMapFragment or MapFragment. In onCreateView you have to wrap your MapView in a customized FrameLayout (in example below it is the class "TouchableWrapper"), in which you intercepts touch events and recognizes whether the map is tapped or not. If your "onCameraChange" gets called, just check whether the map view is pressed or not (in example below this is the variable "mMapIsTouched").
Example code:
UPDATE 1:
return original created view in getView()
use dispatchTouchEvent() instead of onInterceptTouchEvent()
Customized FrameLayout:
private class TouchableWrapper extends FrameLayout {
#Override
public boolean dispatchTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
mMapIsTouched = true;
break;
case MotionEvent.ACTION_UP:
mMapIsTouched = false;
break;
}
return super.dispatchTouchEvent(ev);
}
}
In your customized MapFragment:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent,
Bundle savedInstanceState) {
mOriginalContentView = super.onCreateView(inflater, parent,
savedInstanceState);
mTouchView = new TouchableWrapper(getActivity());
mTouchView.addView(mOriginalContentView);
return mTouchView;
}
#Override
public View getView() {
return mOriginalContentView;
}
In your camera change callback method:
private final OnCameraChangeListener mOnCameraChangeListener =
new OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
if (!mMapIsTouched) {
refreshClustering(false);
}
}
};

OUTDATED Use the new maps API instead. See answer from punksta.
After using AZ13's solution above, and running into the problem mentioned in the comments, I created the following solution, that solves the issue more reliably. However, since I am using a timer after the onRelease event to determine whether the map is still animating, there is a slight delay in this solution.
The code can be found on Github via this link: https://github.com/MadsFrandsen/MapStateListener
My solution can be used from an activity in the following way:
new MapStateListener(mMap, mMapFragment, this) {
#Override
public void onMapTouched() {
// Map touched
}
#Override
public void onMapReleased() {
// Map released
}
#Override
public void onMapUnsettled() {
// Map unsettled
}
#Override
public void onMapSettled() {
// Map settled
}
};

I would try a onCameraChangeListener. The listener is called every time a movement of the camera is finished. The listener will also give you the new location. In my tests the listener was called pretty often during dragging maybe there is a better solution.

The simplest way is to use setOnCameraIdleListener method to handle your move end state of touch listener on your map fragment.
see the example below:
mMap.setOnCameraMoveStartedListener(new GoogleMap.OnCameraMoveStartedListener() {
#Override
public void onCameraMoveStarted(int i) {
mapPin.startAnimation(animZoomOut);
}
});
mMap.setOnCameraIdleListener(new GoogleMap.OnCameraIdleListener() {
#Override
public void onCameraIdle() {
mapPin.startAnimation(animZoomIn);
}
});

Starting with play-services-maps 9.4.0 you can simply use GoogleMap.OnCameraMoveStartedListener, GoogleMap.OnCameraMoveListener and GoogleMap.OnCameraIdleListener.
If, for some reason, you want to use the older API which is now deprecated you can use onCameraChangeListener. But you have to be aware of two things:
onCameraChange() might be called many times while you drag the map OR only once (when dragging stopped).
The camera position in the last call of onCameraChange() can be slightly different from the final camera position.
The following code takes both issues into account:
private static final int MESSAGE_ID_SAVE_CAMERA_POSITION = 1;
private static final int MESSAGE_ID_READ_CAMERA_POSITION = 2;
private CameraPosition lastCameraPosition;
private Handler handler;
private GoogleMap googleMap;
public void onMapReady(GoogleMap theGoogleMap) {
googleMap = theGoogleMap;
handler = new Handler() {
public void handleMessage(Message msg) {
if (msg.what == MESSAGE_ID_SAVE_CAMERA_POSITION) {
lastCameraPosition = googleMap.getCameraPosition();
} else if (msg.what == MESSAGE_ID_READ_CAMERA_POSITION) {
if (lastCameraPosition.equals(googleMap.getCameraPosition())) {
Log.d(LOG, "Camera position stable");
}
}
}
};
googleMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
handler.removeMessages(MESSAGE_ID_SAVE_CAMERA_POSITION);
handler.removeMessages(MESSAGE_ID_READ_CAMERA_POSITION);
handler.sendEmptyMessageDelayed(MESSAGE_ID_SAVE_CAMERA_POSITION, 300);
handler.sendEmptyMessageDelayed(MESSAGE_ID_READ_CAMERA_POSITION, 600);
}
});
}

On camera idle is what you should use now
googleMap.setOnCameraIdleListener(new GoogleMap.OnCameraIdleListener() {
#Override
public void onCameraIdle() {
//Called when camera movement has ended, there are no pending animations and the user has stopped interacting with the map.
}
});

I have to animate my marker to center as long as the user drag the map. I have implemented it using Stas Shakirov answer

I think the event onclick in the map is: map.setOnMapClick...
But event drag is: map.onCameraChangeListener because I call a log.e in both of that functions and it shown like onClick view and onDrag view . So just using them for you.

Enhanced solution with an Handler inner Class in Xamarin Android, based on Tobus answer:
public void OnMapReady(GoogleMap googleMap)
{
_googleMap = googleMap;
if (_googleMap != null)
{
_cameraPositionHandler = new CameraPositionlHandler(_googleMap);
_googleMap.CameraChange += OnCameraChanged;
}
}
void OnCameraChanged (object sender, GoogleMap.CameraChangeEventArgs e)
{
_cameraPositionHandler.RemoveMessages(MESSAGE_ID_SAVE_CAMERA_POSITION);
_cameraPositionHandler.RemoveMessages(MESSAGE_ID_READ_CAMERA_POSITION);
_cameraPositionHandler.SendEmptyMessageDelayed(MESSAGE_ID_SAVE_CAMERA_POSITION, 300);
_cameraPositionHandler.SendEmptyMessageDelayed(MESSAGE_ID_READ_CAMERA_POSITION, 600);
}
With the following inner Class:
private class CameraPositionlHandler : Handler
{
private CameraPosition _lastCameraPosition;
private GoogleMap _googleMap;
public CameraPositionlHandler (GoogleMap googleMap)
{
_googleMap = googleMap;
}
public override void HandleMessage(Message msg)
{
if (_googleMap != null)
{
if (msg.What == MESSAGE_ID_SAVE_CAMERA_POSITION) {
_lastCameraPosition = _googleMap.CameraPosition;
} else if (msg.What == MESSAGE_ID_READ_CAMERA_POSITION) {
if (_lastCameraPosition.Equals(_googleMap.CameraPosition)) {
Console.WriteLine("Camera position stable");
//do what you want
}
}
}
}
}
