Why can't I access a button added to a custom info window added to a marker in Google Maps?

I'm creating a small app that will help a user find a sports club. Based on the type of sport picked from a spinner in the previous activity a number of markers representing different clubs will be shown on a map.(See screenshot below)
Results after a type of sport is clicked in a spinner
I've attempted to add a button to an information window (contains a title, and a snippet) of a marker in Google Maps that will start another activity. It will produce a toast pop up for now. At the moment I'm producing the following result:
App Screenshot (unable to embed image as reputation too low)
The issue I'm having is that I cannot interact with the button in the info window when I try to click the button the whole information window gets clicked instead (leads to the window changing from a white to a grey background to show it was clicked). This happens whether I try to click the button or any other section of the information window.
Grey background to signify info window was clicked
To do this I created an XML layout file (custom_window_info.xml) that would be displayed in the map activity in the event of a marker being clicked. It displays the title, snippet and the button method declared in the MapActivity.java class.
I then created a java class (CustomInfoWindowAdapter.java) that provided the java functionality for the layout file mentioned above, e.g. assigning the values to the title and snippet text fields, the getInfoWindow() and getInfoContents() methods, etc.
I'm not sure If I've approached this the wrong way entirely or I'm making a little mistake. Any tips/suggestions?

Actually, it not possible, Google Map renders the content of your custom InfoWindow into an image and displays it to you as an Image. Therefore you set a click Listener only to the whole window and not to the Views inside it.
Your only choice is to set the ClickListener to the whole InfoWindow and popup a Dialog with clickable content you want, and not do it directly inside the InfoWindow.
From Google Docs: https://developers.google.com/maps/documentation/android/marker#info_windows
Note: The info window that is drawn is not a live view. The view is rendered as an image (using View.draw(Canvas)) at the time it is returned. This means that any subsequent changes to the view will not be reflected by the info window on the map. To update the info window later (e.g., after an image has loaded), call showInfoWindow(). Furthermore, the info window will not respect any of the interactivity typical for a normal view such as touch or gesture events. However, you can listen to a generic click event on the whole info window as described in the section below.`

Close PopupWindow upon tapping outside or back button

I want to close a PopupWindow by either tapping outside the window or pressing a back button. Right now you can tap anywhere on the screen and the window closes, and I can't figure out why. I'd also like to add a shadow to the PopupWindow. Thanks!

Sorry about the noob question. I've been at this for a while and I just can't seem to figure out no matter how much I try... my biggest two concerns are getting the shadow behind the popupwindow and also closing it upon the press of the back button or tapping outside the popup window. thanks very much in advance. thanks.

You will need to set Background Drawable using and on Outside touch true
popWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable())
popupWindow.setOutsideTouchable(true);
method by passing any drawable. Otherwise the whole screen is your background and tapping outside will not work backPressed will work automatically using this way!
To add a shadow to you PopupWindow the easier way is to put CardView as the root of your View in xml and change elevation attribute. To use CardView you may have to add a dependency it in your gradle file as well
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/card_view"
android:layout_gravity="center"
android:layout_width="200dp"
android:layout_height="200dp"
card_view:cardElevation="4dp"
card_view:cardCornerRadius="4dp">
<!--YOUR RELATIVE LAYOUT SHOULD BE HERE!-->
</android.support.v7.widget.CardView>
You also have to add dependency in your app gradle files like:
dependencies {
...
compile 'com.android.support:cardview-v7:21.0.+'
}
More details in CardView and elevation here.
THIS IS HOW IT LOOKS IN MY CODE
LayoutInflater layoutInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// inflate the custom popup layout
final View inflatedView = layoutInflater.inflate(R.layout.pop_up_test, null,false);
// get device size
Display display = getWindowManager().getDefaultDisplay();
final Point size = new Point();
display.getSize(size);
//mDeviceHeight = size.y; //Not in use just comment it off for now
// set height depends on the device size
popupWindow = new PopupWindow(inflatedView, size.x - 50,(WindowManager.LayoutParams.WRAP_CONTENT), true );
// set a background drawable with rounders corners
// make it focusable to show the keyboard to enter in `EditText`
popupWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable());//This has no meaning than dismissal of the Pop Up Noni!!
// make it outside touchable to dismiss the popup window
popupWindow.setOutsideTouchable(true);
// show the popup at bottom of the screen and set some margin at bottom ie,
popupWindow.showAtLocation(v, Gravity.BOTTOM, 0,100);

I could override your onBackPressed() method in your Activity. That being said, if you press your back button this method is fired. In that method you can check wether the popup is showing, and dissmiss it if needed, like this:
#Override
public void onBackPressed() {
if (popupWindow != null && popupWindow.isShowing()) {
popupWindow.dismiss();
}
super.onBackPressed();
}
You can implement the dismiss() logic also with some onClickListeners from the area's you want the user to click to cancel the popup.

If you don't want to use Xenolion asnwer for whatever reason, You can just create backdrop manually which goes over your whole screen.
Add whatever on top of it.
Add onclick listener on backdrop which closes backdrop and window.
Add onclick listener on popupwindow as null that will prevent from closing pop up when clicked on top of it.

I had popups that would not be dismissed by either back button or tap outside on Android 5. I worked great on newer Android versions, just not on Android 5, Lollipop, API level 21.
All that was needed in my case was:
popupWindow.setBackgroundDrawable(new ColorDrawable())
Go figure!

Display infowindow android Maps

How to display marker infowindow when map loads? when im clicking the map name a new activity starts where the map loads.It shows the marker,the problem is i want to automatically display also the custom infowindow i created.Here's my code below: I will mark this answer for those who can fix this. thanks.
if (nameList.get(i).equals(selected)){
Marker marker = map.addMarker(new MarkerOptions()
.title(nameList.get(i))
.snippet(addressList.get(i))
.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker_location))
.position(new LatLng(latList.get(i), lngList.get(i))));
marker.showInfoWindow();
//Set Custom InfoWindow
map.setInfoWindowAdapter(new InfoWindowAdapter() {
#Override
public View getInfoWindow(Marker arg0) {
return null;
}
#Override
public View getInfoContents(Marker marker) {
View myContentsView = getLayoutInflater().inflate(R.layout.map_info, null);
TextView tvTitle = ((TextView)myContentsView.findViewById(R.id.title));
tvTitle.setText(marker.getTitle());
TextView tvSnippet = ((TextView)myContentsView.findViewById(R.id.snippet));
tvSnippet.setText(marker.getSnippet());
TextView infoSnippet = (TextView)myContentsView.findViewById(R.id.moreinfo);
infoSnippet.setText("Click for more details.");
return myContentsView;
}
});
//Open New Activity
map.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker marker) {
Intent intent = new Intent(SelectedPlaceActivity.this, PlaceDescriptionActivity.class);
intent.putExtra("placetitle", marker.getTitle().toString());
intent.putExtra("snippet", marker.getSnippet().toString());
startActivity(intent);
}
});
}

It seems that you need an InfoWindow adapter. See the following example:
map.setInfoWindowAdapter(new InfoWindowAdapter(){
// Use default InfoWindow frame
#Override
public View getInfoWindow(Marker marker) {
return null;
}
// Defines the contents of the InfoWindow
#Override
public View getInfoContents(Marker marker) {
// Getting view from the layout file info_window_layout
View v = getLayoutInflater().inflate(R.layout.custom_info_window, null);
// Getting reference to the TextView to set title
TextView note = (TextView) v.findViewById(R.id.note);
note.setText(marker.getTitle() );
return v;
}
});
As you can see, you need to create a custom layout. In my example:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView android:id="#+id/note"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:textColor="#000000"/>
<ImageButton android:id="#+id/takeMeThere"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/note"
android:contentDescription="#string/directions"
android:src="#drawable/ic_action_directions"
android:background="#null"/>
</RelativeLayout>
Hope this helps

According to the documents of Google Maps for Android V2:
An info window allows you to display information to the user when they
tap on a marker on a map. By default, an info window is displayed when
a user taps on a marker if the marker has a title set. Only one info
window is displayed at a time. If a user clicks on another marker, the
current window will be hidden and the new info window will be
displayed. You can show an info window programmatically by calling
showInfoWindow() on the target marker. An info window can be hidden by
calling hideInfoWindow().

Android Google Map API V2 : Open Custom Info Window on Right Side of Marker

I have Integrated Google MAP API V2 for Android. I want to have a Custom Info Window at Onclick of My Marker. Up to that it is fine. i have integrate it.
What I want : I want to Show my Custom Info Window on Right Side of Marker Instead of Top of the Marker.

Now , I want to have my custom InfoWindow to the Right Side of the Marker instead of Top.
All Helps are Appreciated.
Thanks in Advance.

Edit 2:
Starting from September update (v12 or 3.2.65) of the Google Maps Android API v2 MarkerOptions.infoWindowAnchor was added. There are quite a few new functions, so check release notes too.
Edit 3:
Unfortunatelly this addition doesn't solve your problem yet. Added new issue for that.
This is not currently possible.
Trying to work around it by putting a View over MapFragment can be a good solution if users are not allowed to move the map. If they can, you will see some bad lags on repositioning when using either "push techonology" onCameraChange or polling with Handler and map.getCameraPosition().
Same problems if you try to use additional marker with transparent icon to show info window on when the visible is clicked, but it would be more fun to see it actually implemented.
If you can live without info window on the right for now, I would suggest starring this feature already requested and waiting.
Edit:
As of 3.1.36 (rev. 7) of the API v2 you can change the icon of marker. This means you can make two icons: one normal, and another that looks like you have an info window open on the right. Disabling opening default info window and using this instead might work for you.

You can do by simple convert marker.getPosition() to screenPosition like below code
Projection projection = map.getProjection();
LatLng markerLocation = marker.getPosition();
Point screenPosition = projection.toScreenLocation(markerLocation);
int x = screenPosition.x +marker. markerImage.getWidth();
You can ref below link for more infomation (which convert getPosition to projection):

Android - setInfoWindowAdapter with WebView in google Marker (api v2)

I have a problem with marker on google maps api v2.
I would like to customize infoWindows with a WebView:
Here my code of InfoWindowAdapter
mMap.setInfoWindowAdapter(new InfoWindowAdapter() {
#Override
public View getInfoWindow(Marker arg0) {
return null;
}
#Override
public View getInfoContents(Marker arg0) {
View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);
TextView title = (TextView) v.findViewById(R.id.title_marker);
WebView snippet = (WebView) v.findViewById(R.id.item_snippet);
title.setText(arg0.getTitle());
snippet.setVisibility(WebView.VISIBLE);
snippet.loadData(arg0.getSnippet(),"text/html", "UTF-8");
return v;
}
});
And this is the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/title_marker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<WebView
android:id="#+id/item_snippet"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
My problem is that I see the content into the TextView, but not the content into the WebView.
What i'm doing wrong?
Thanks a lot

You can't use a WebView directly. The reason is (source: official docs):
Note: The info window that is drawn is not a live view. The view is rendered as an image (using View.draw(Canvas)) at the time it is returned. This means that any subsequent changes to the view will not be reflected by the info window on the map. To update the info window later (e.g., after an image has loaded), call showInfoWindow(). Furthermore, the info window will not respect any of the interactivity typical for a normal view such as touch or gesture events. However you can listen to a generic click event on the whole info window as described in the section below.
You can try drawing the webview on a bitmap (after the content has been loaded) and supplying an ImageView with that bitmap in the InfoWindow adapter, but you will lose interactivity with the webview anyway.

after a lot of tests, googling and some reversing I can say that view you return in getInfoContents is used to render into a Bitmap and then hidden. The bitmap is then displayed via GL
I've found a workaround that can be fine for you.
private View mGhost;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mGhost = new View(this);
mGhost.setLayoutParams(new LayoutParams(0, 0));
mGhost.setVisibility(View.GONE);
....
}
public void onMapReady(GoogleMap map) // or whatever
{
map.setInfoWindowAdapter(new InfoWindowAdapter()
{
#Override
public View getInfoWindow(Marker marker)
{
return null;
}
#Override
public View getInfoContents(final Marker marker)
{
WebView webview = new WebView(MainActivity.this);
webview.loadUrl(marker.getSnippet());
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
AlertDialog alert = builder.setView(webview).create();
alert.show();
alert.getWindow().setLayout(200, 200);
mGhost.post(new Runnable()
{
#Override
public void run()
{
marker.hideInfoWindow();
}
});
return mGhost;
}
});
}
in this example I've used the snippet to store the url, It's not exactly what did you asked, but it may look similar.
Edit: the first version was recycling the WebView but it's not possible without some trick to remove it from the Alert, this revised version doesn't shows the InfoContents box below but has still an issue, when pressed it keeps a sort of state, and it believes the marker is clicked after closing the dialog.
You may use a layout that contains a WebView to decor a bit the window
Edit2: Reverted to something like the first version, a blank InfoContents box shows for bit I'm not sure it's avoidable.
