InfoWindow Content Click is not working for layouts In Android

I'm using google map in my application ,when I click the marker info-window is opened again I want to click the info-window layout but its not working for layouts.If I give click listener for button means its working.Please help me to fix this issue.

Note:Here I give click listener for textview ,the textview present inside the layout.

How to access custom parameters in AsyncTask?

I want to load images asynchronously and show them on the infowindow. For this I made a custom class to store parameters. I need for this (marker, image) but my code throws a runtime exception saying it can't call getPosition on the marker I stored in the custom class instance.
What is the correct way to use AsyncTask with custom class instance parameters?
This is my code:
googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
LatLng latLng = marker.getPosition();
// find location id in database
Location location = dbhandler.getLocationByLatLng(latLng);
final int id = location.getId();
addButton.setVisibility(View.VISIBLE);
addButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// open load image fragment
android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
LoadImageFragment fragment = new LoadImageFragment();
// pass id to new fragment
Bundle bundle = new Bundle();
bundle.putInt("id", id);
fragment.setArguments(bundle);
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.commit();
}
});
removeButton.setVisibility(View.VISIBLE);
removeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// remove markers and images
}
});
class TaskParams {
Marker marker;
Location location;
Image image;
TaskParams() {
}
public Location getLocation() {
return this.location;
}
public Marker getMarker() {
return this.marker;
}
public Image getImage(){
return this.image;
}
public void setMarker(Marker marker) {
this.marker = marker;
}
public void setLocation(Location location) {
this.location = location;
}
public void setImage(Image image) {
this.image = image;
}
}
TaskParams taskParams = new TaskParams();
taskParams.setMarker(marker);
new AsyncTask<TaskParams, Void, TaskParams>() {
#Override
protected TaskParams doInBackground(TaskParams... params) {
TaskParams tParams = params[0];
Marker m = tParams.getMarker();
LatLng latLng = m.getPosition();
Location location = dbhandler.getLocationByLatLng(latLng);
tParams.setLocation(location);
return tParams;
}
// find image and text associated with Location
protected void onPostExecute(TaskParams taskParams) {
new AsyncTask<TaskParams, Void, TaskParams>() {
#Override
protected TaskParams doInBackground(TaskParams... params) {
TaskParams tParams = params[0];
Location location = tParams.getLocation();
try {
image = dbhandler.getImageByLocationId(location.getId());
tParams.setImage(image);
}
catch (Exception ex){
Log.d("debug", "failed to fetch image");
image = null;
}
return tParams;
}
#Override
protected void onPostExecute(TaskParams taskParams) {
Image image = taskParams.getImage();
// set image and description
if(image != null) {
infoImageView.setImageBitmap(image.getBitmap());
infoTextView.setText(image.getDescription());
Marker marker = taskParams.getMarker();
marker.showInfoWindow();
updateInfoWindow(image);
}
}
}.execute(taskParams);
}
}.execute(taskParams);
//marker.showInfoWindow();
return true;
}
});
// find Location in database
// Setting a custom info window adapter for the google map
googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {
// Use default InfoWindow frame
#Override
public View getInfoWindow(Marker arg0) {
return null;
}
// Defines the contents of the InfoWindow
#Override
public View getInfoContents(Marker arg0) {
// Getting view from the layout file info_window_layout
View v = getActivity().getLayoutInflater().inflate(R.layout.info_window_layout, null);
// Getting the position from the marker
final LatLng latLng = arg0.getPosition();
infoImageView = (ImageView) v.findViewById(R.id.infoImage);
infoTextView = (TextView) v.findViewById(R.id.infoText);
if(image != null) {
infoImageView.setImageBitmap(image.getBitmap());
infoTextView.setText(image.getDescription());
}
return v;
}
});

You can override the constructor. Something like:
private class MyAsyncTask extends AsyncTask<Void, Void, Void> {
public MyAsyncTask(boolean showLoading) {
super();
// do stuff
}
// doInBackground() et al.
}
Then, when calling the task, do something like:
new MyAsyncTask(true).execute(maybe_other_params);
This is more useful than creating member variables because it simplifies the task invocation. Compare the code above with:
MyAsyncTask task = new MyAsyncTask();
task.showLoading = false;
task.execute();

Google maps loading slow inside fragment

I have main activity with fragments and one of the fragments is Map Fragment. Now, when i tap there, every time it opens slow. I am using singleton instance of fragment, but it still doesnt work as expected. Here is a good of that class:
public MapsFragment() {
gson = new Gson();
}
public static MapsFragment getInstance() {
if (mInstance == null)
mInstance = new MapsFragment();
return mInstance;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable final Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.fragment_maps, container, false);
mOnSavedinstance = savedInstanceState;
mMapView = (MapView) v.findViewById(R.id.map);
mMapWrapperLayout = (MapWrapperLayout) v.findViewById(R.id.map_relative_layout);
mMapView.getMapAsync(MapsFragment.this);
mMapView.onCreate(savedInstanceState);
mMapView.requestFocus();
MapsInitializer.initialize(getActivity());
return v;
}
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
// MapWrapperLayout initialization
// 39 - default marker height
// 20 - offset between the default InfoWindow bottom edge and it's content bottom edge
mMapWrapperLayout.init(mGoogleMap, Constants.MARKER_HEIGHT);
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
mGoogleMap.setMyLocationEnabled(false);
}
mGoogleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
setUpMap();
}
private void setUpMap() {
new Thread(new Runnable() {
#Override
public void run() {
final ArrayList<MarkerOptions> markerOptionses = new ArrayList<MarkerOptions>();
int counter = 0;
for (final Places places : Model.getInstance().getPlaces()) {
LatLng location = new LatLng(Double.parseDouble(places.getLat()), Double.parseDouble(places.getLon()));
final MarkerOptions options = new MarkerOptions();
options.snippet(gson.toJson(places));
options.position(location);
options.title(String.valueOf(counter));
markerOptionses.add(options);
counter++;
}
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
for (MarkerOptions markerOptionse : markerOptionses) {
mGoogleMap.addMarker(markerOptionse).setIcon(BitmapDescriptorFactory.fromResource(Model.getInstance().getPlaces()
.get(Integer.parseInt(markerOptionse.getTitle())).getMapsRes(getActivity())));
}
}
});
final CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(45.4654, 9.1859)) // Sets the center of the map to location user
.zoom(Constants.CAMERA_ZOOM_LOCATION) // Sets the zoom
.build(); // Creates a CameraPosition from the builder
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
mGoogleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
mGoogleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mGoogleMap.setOnMapClickListener(MapsFragment.this);
// mGoogleMap.setOnInfoWindowClickListener(mInfoListener);
}
});
}
}).start();
}
#Override
public void onResume() {
mMapView.onResume();
super.onResume();
}
#Override
public void onDestroy() {
super.onDestroy();
mGoogleMap.clear();
mMapView.onDestroy();
}
#Override
public void onLowMemory() {
super.onLowMemory();
mMapView.onLowMemory();
}

You can try to add markers only if it would be visible? I mean: first move camera to start position and set zoomLevel and just after that add Markers but only if it's in visible sector. And update markers on camera move.

Use AlphaBar on polygon google maps v2 Android

I am working on map application Android and try use AlphaSeekBar to my polygons on Google Maps v2 Android.
I try to use that SeekBar working on my all polygons, but it turns out just working on last polygon.
This is my code:
private static final int ALPHA_MAX = 255;
private SeekBar mAlphaBar;
private Polygon mMutablePolygon;
private GoogleMap mMap;
.........................................
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_kabupaten);
mAlphaBar = (SeekBar) findViewById(R.id.alphaSeekBar);
mAlphaBar.setMax(ALPHA_MAX);
mAlphaBar.setProgress(127);
mMessageView = (TextView) findViewById(R.id.message_text);
setUpMapIfNeeded();
}
#Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
mMap.setMyLocationEnabled(true);
mMap.setPadding(currentLeft, currentTop, currentRight, currentBottom);
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(DR, 14));
// poligon area --
{
PolygonOptions options = new PolygonOptions()
.add(dr_1,dr_2,dr_3,dr_4,dr_5,dr_6,dr_7,dr_8,dr_9,dr_10,dr_11,dr_12,dr_13,dr_14,dr_15,dr_16,dr_17) ;
mMutablePolygon = mMap.addPolygon(options
.strokeColor(Color.RED)
.strokeWidth(1)
.fillColor(Color.CYAN));
PolygonOptions gt =new PolygonOptions()
.add(gt_1,gt_2,gt_3,gt_4,gt_5,gt_6,gt_7,gt_8,gt_9,gt_10,gt_11,gt_12,gt_13,gt_14,gt_15,gt_16) ;
mMutablePolygon = mMap.addPolygon(gt
.strokeColor(Color.RED)
.strokeWidth(1)
.fillColor(Color.GREEN));
mAlphaBar.setOnSeekBarChangeListener(this);
}
// Add a camera change listener.
mMap.setOnCameraChangeListener(new OnCameraChangeListener() {
public void onCameraChange(CameraPosition pos) {
mMessageView.setText("CameraChangeListener: " + pos);
}
});
}
}
}
public void onStopTrackingTouch(SeekBar seekBar) {
// Don't do anything here.
}
public void onStartTrackingTouch(SeekBar seekBar) {
// Don't do anything here.
}
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (mMutablePolygon == null) {
return;
}
if (seekBar == mAlphaBar) {
int prevColor = mMutablePolygon.getFillColor();
mMutablePolygon.setFillColor(Color.argb(
progress, Color.red(prevColor), Color.green(prevColor),
Color.blue(prevColor)));
}
}
}

The problem is that you are keeping just one reference to polygon
If you want to update all of them, you need to use a List mMutablePolygons;
Then when each polygon is created:
mPolygon = mMap.addPolygon(options
.strokeColor(Color.RED)
.strokeWidth(1)
.fillColor(Color.CYAN));
mMutablePolygons.add(mPolygon);
and when changing the seekbar value:
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (mMutablePolygons == null || mMutablePolygons.isEmpty()) {
return;
}
if (seekBar == mAlphaBar) {
for(Polygon mpoly : mMutablePolygons){
int prevColor = mpoly.getFillColor();
mpoly.setFillColor(Color.argb(progress, Color.red(prevColor), Color.green(prevColor),Color.blue(prevColor)));
}
}
}

Android: MapView not responding after Resume

I have a strange problem with a com.google.android.gms.maps.MapView.
To check if my App crashes after the garbage collector is doing his job i force my HTC One (4.2.2) to allow only 1 running app in background. If I leave my app(home button) while showing a MapView, start any other app and resume to my app, my MapView is still showing up...but I can not move or zoom the map, it's not responding at all. Other activities are working fine. I really have no clue where the problem might be.
Hope that someone can help me out?
Here is the sourcecode of my fragment that shows the MapView
public class FragmentAdvertlistMap extends Fragment {
com.google.android.gms.maps.MapView m;
GoogleMap mMap;
ArrayList<Advert> ads;
HashMap<Marker, String> myMarker;
public final LatLngBounds.Builder builder= new LatLngBounds.Builder();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
try {

m = (com.google.android.gms.maps.MapView)inflatedView.findViewById(R.id.map_tab);
m.onCreate(savedInstanceState);
myMarker = new HashMap<Marker, String>();
ads= AdvertListActivity.getAdverts();
setUpMapIfNeeded(inflatedView);
mMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker arg0) {
Intent myIntent = new Intent(getActivity(), AdvertLocationActivity.class);
Advert putadvert = DefaultApplication.dbc.getAdvertForAdvertID(Integer.parseInt(myMarker.get(arg0)));
myIntent.putExtra("advert", putadvert);
startActivity(myIntent);
}
});
return inflatedView;
}
private void setUpMapIfNeeded(View inflatedView) {
if (mMap == null) {
mMap = ((com.google.android.gms.maps.MapView) inflatedView.findViewById(R.id.map_tab)).getMap();
if (mMap != null) {
this.initMarker();
}
}
}
public void initMarker(){
for(int i=0;i<ads.size();i++){
Advert tempAd = ads.get(i);
LatLng tlalo = new LatLng(tempAd.mainLocation.latitude,tempAd.mainLocation.longitude);
builder.include(tlalo);
String address = "";
if(tempAd.mainLocation.contact_street != null){
address = address + tempAd.mainLocation.contact_street;
}
if(tempAd.mainLocation.contact_street_number != null){
address = address + " " + tempAd.mainLocation.contact_street_number;
}
Marker marker = mMap.addMarker(new MarkerOptions()
.position(tlalo)
.anchor(0.5f, 0.5f)
.title(tempAd.name)
.snippet(address)
.icon(BitmapDescriptorFactory.fromResource(R.drawable.androidpin)));
myMarker.put(marker,String.valueOf(tempAd.myid));
}
mMap.setOnCameraChangeListener(new OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition arg0) {
mMap.moveCamera(CameraUpdateFactory.newLatLngBounds(builder.build(), 100));
mMap.setOnCameraChangeListener(null);
}
});
}
#Override
public void onResume() {
super.onResume();
m.onResume();
}
#Override
public void onPause() {

}
#Override
public void onDestroy() {

m.onDestroy();
}
#Override
public void onLowMemory() {

}
}

try add this in onCreateView()
container.removeAllViews();
I found it in another similar question to yours but I lost the original link of the answer...
