Skobbler annotation with button

I am creating a Skobbler Annotation as follows:
markerCoords = mapView.pointToCoordinate(skScreenPoint); //gives us the coordinate
SKAnnotation annotation = new SKAnnotation(11);
SKAnnotationView view = new SKAnnotationView();
View v = getLayoutInflater().inflate(R.layout.annotation_marker, null, false);
v.findViewById(R.id.btn_destination).setOnClickListener(destListener);
v.findViewById(R.id.btn_origin).setOnClickListener(originListener);
view.setView(v);
annotation.setAnnotationView(view);
annotation.setLocation(mapView.pointToCoordinate(skScreenPoint));
annotation.setMininumZoomLevel(1);
mapView.addAnnotation(annotation, SKAnimationSettings.ANIMATION_POP_OUT);
The view R.layout.annotation_marker contains a couple of buttons, but I can't tap/click them. My click goes through the annotation and hits the map instead (I've detected it). I've tried using requestFocus() on the view when I inflate it, but that has no effect. I also have android:clickable='true' in the xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="200dp"
android:layout_height="110dp"
android:layout_gravity="center_horizontal">
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Origin"
android:id="#+id/btn_origin"
android:layout_gravity="right"
android:focusable="true"
android:clickable="true"/>
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:text="Destination"
android:id="#+id/btn_destination" />
</LinearLayout>
How do I get the click event to hit the buttons instead of the underlying map?

Since the onClick event doesn’t happen, the solution in order to enable events on different views situated on map is incorporating them in different annotations using annotationViews and the execute actions on the onAnnotationSelected callback(so there should be one view per annotation).
In order to make an event trigger in a natural manner a corresponding offset must be set to the annotation so as the onAnnotationSelected callback to be triggered when the actual view is clicked, not the extension of the annotation.
#Override
public void onSurfaceCreated(SKMapViewHolder mapHolder) {
….
SKAnnotation annotation = new SKAnnotation(137);
SKAnnotationView annotationView = new SKAnnotationView();
View v = getLayoutInflater().inflate(R.layout.bug_2_btn_layout,null,false);
annotationView.setView(v);
annotation.setAnnotationView(annotationView);
annotation.setLocation(new SKCoordinate(52.520008,13.404954));
annotation.setMininumZoomLevel(1);
double viewToLayoutRatio = getResources().getDimension(R.dimen.originBtn_width)/getResources().getDimension(R.dimen.annotationLayout_width);
annotation.setOffset(new SKScreenPoint((float) (annotation.getOffset().getX()-(viewToLayoutRatio*getResources().getDimension(R.dimen.originBtn_width))), (float) (annotation.getOffset().getY()+(viewToLayoutRatio/3)*getResources().getDimension(R.dimen.originBtn_width))));
mapView.addAnnotation(annotation, SKAnimationSettings.ANIMATION_POP_OUT);
…
}
#Override
public void onAnnotationSelected(final SKAnnotation annotation) {
switch (annotation.getUniqueID()) {
…
case 137:
Toast.makeText(getApplicationContext(),"Annotation was clicked",Toast.LENGTH_SHORT);
View v = getLayoutInflater().inflate(R.layout.bug_2_btn_layout,null,false);
originClicked(v);
break;
}
}

How to have the soft keyboard cover a view, yet cause other views to take the available space?

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 workaround to detect the keyboard size, and show only the upper area of the background view, but there is little control of the MapFragment in how it looks and work.
Here's a demo of the problem:
Here's a sample xml, used inside the sample of the mapFragment:
basic_demo.xml
<FrameLayout
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">
<fragment
android:id="#+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<EditText
android:id="#android:id/edit"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="20dp"
android:background="#66ffffff"
android:digits="0123456789()-+*"
android:focusable="true"
android:focusableInTouchMode="true"
android:gravity="center_vertical|left"
android:imeOptions="actionSearch|flagNoExtractUi"
android:inputType="phone"
android:singleLine="true"
android:textColorHint="#aaa"
android:textSize="18dp"
tools:hint="Search Phones ..."/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginBottom="30dp"
android:background="#66ffffff"
android:text="This should always be shown, at the bottom"/>
</FrameLayout>
What I've found
I know that we can set the "windowSoftInputMode" flag in the manifest, but this is an all-or-nothing solution. It affects all of the views, and not a single one.
The question
How can I let the soft keyboard change the layout of all views except specific ones?
Is it even possible?
EDIT: looking at "gio"'s solution, it works. Here's a more optimized way to do it:
View view=...
mContainerView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
final Rect outGlobalRect = new Rect(), outWindowRect = new Rect();
#Override
public void onGlobalLayout() {
mContainerView.getGlobalVisibleRect(outGlobalRect);
mContainerView.getWindowVisibleDisplayFrame(outWindowRect);
int marginBottom = outGlobalRect.bottom - outWindowRect.bottom;
final FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) view.getLayoutParams();
if (layoutParams.bottomMargin == marginBottom)
return;
layoutParams.setMargins(0, 0, 0, marginBottom);
view.requestLayout();
}
});

It's possible according your initial requirements. Idea is to change bottom margin of needed view. Value will be calculated as difference between shown and real height of root view. I wrapped TextView into FrameLayout for case if you need to control more views there.

mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
Result:

This is a little bit off topic from what you guys have been discussing, but I had the same issue with the Google Map layout being re adjusted when user clicks on an EditText on that fragment layout. My problem was that the GoogleMap was a fragment of another view (ViewPager). In order to fix it, I had to programmatically add getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN) to the ViewPager Class.
Layout Hierarchy: Activity --> ViewPager --> GoogleMap Fragment. Code added to ViewPager on the onCreate method.

How can I prevent an ImageView from resizing its parent? [duplicate]

This question already has answers here:
Scale Image to fill ImageView width and keep aspect ratio
(16 answers)
Closed 5 years ago.
Note: I have checked this question, but none of the answers helped. I'm restating the question to specify my specific problems and needs.
I've made a custom view in my android app that displays data for an upcoming event (title, location, price, description, etc). In addition to this data, there are also icon and cover photos displayed on this view (the icon is displayed in an ImageView in the upper-left corner of the view and the cover is modified to have an alpha of 128, then displayed behind the content of the view. Here's my layout so far:

When an Activity instantiates my view, it must supply a source for the data (a custom class). It is then (under setSource()) that a method updateLayout() is called, which sets the icon image, and the various TextViews. Additionally, it sets the eventview_cover's source to a BitmapDrawable (to modify the original photo's alpha). That, in turn, extends the height of the view (which I want to avoid). The height of the view should only be governed by the heights of the TextViews and the ImageView for the icon. Here's the code for EventView:
public class EventView extends RelativeLayout {
private MergeEvent src = null;
public MergeEvent getSource() {
return src;
}
protected void setSource(MergeEvent e) {
src = e;
//The data was updated, so we need to update the view!
updateLayout();
}
public EventView(MergeEvent src, Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
setSource(src);
}
public EventView(MergeEvent src, Context context, AttributeSet attrs) {
super(context, attrs);
setSource(src);
}
public EventView(MergeEvent src, Context context) {
super(context);
setSource(src);
}
protected void updateLayout() {
if (getSource() != null) {
//Get source data.
MergeEvent src = getSource();
//Set the layout.
View.inflate(getContext(), R.layout.eventview, this);
//Get references to the TextViews and ImageViews
TextView title = (TextView)findViewById(R.id.eventview_title),
price = (TextView)findViewById(R.id.eventview_price),
location = (TextView)findViewById(R.id.eventview_location),
shortdesc = (TextView)findViewById(R.id.eventview_shortdesc);
ImageView icon = (ImageView)findViewById(R.id.eventview_icon),
cover = (ImageView)findViewById(R.id.eventview_cover);
icon.setImageBitmap(src.getIcon());
title.setText(src.getTitle());
price.setText("$" + src.getPrice());
location.setText(src.getLocation());
shortdesc.setText(src.getShortDescription());
//Create a new BitmapDrawable from the source's cover (a Bitmap)
BitmapDrawable bd = new BitmapDrawable(getResources(), src.getCover());
bd.setAlpha(128);
bkg.setImageDrawable(bd);
requestLayout();
}
}
}
This all works, but it resizes the view to make room for the cover photo, which again, I want to avoid. I tried using getHeight() before I set the drawable, then set the drawable, and set the cover's ImageView's height with bkg.getLayoutParams().height = height, but the call to getHeight() returned 0 because the view is technically not visible at this point, so the cover photo was invisible. The view should look like this, where the background image is cropped and centered:
tl;dr/summary:
How can I prevent an ImageView from resizing its parent?

I found this answer on another question very similar to mine:
This needs to be done using code. You need to call those size APIs a few milliseconds after the screen renders. So, if you call it 100 milliseconds after, using postDelayed method of any view that has been rendered, you will get the sizes.
Using that, I modified my updateLayout() method to this:
protected void updateLayout() {
if (getSource() != null) {
MergeEvent src = getSource();
View.inflate(getContext(), R.layout.eventview, this);
TextView title = (TextView)findViewById(R.id.eventview_title);
TextView price = (TextView)findViewById(R.id.eventview_price);
TextView location = (TextView)findViewById(R.id.eventview_location);
TextView shortdesc = (TextView)findViewById(R.id.eventview_shortdesc);
ImageView i = (ImageView)findViewById(R.id.eventview_icon);
i.setImageBitmap(src.getIcon());
title.setText(src.getTitle());
price.setText("$" + src.getPrice());
location.setText(src.getLocation());
shortdesc.setText(src.getShortDescription());
//use postDelay to set the ImageView's source and max size after 100 miliseconds (plenty of time for the UI to be drawn)
this.postDelayed(new Runnable() {
#Override
public void run() {
BitmapDrawable bd = new BitmapDrawable(getResources(), src.getCover());
bd.setAlpha(128);
ImageView bkg = (ImageView)findViewById(R.id.eventview_cover);
bkg.setMaxHeight(getHeight());
bkg.setImageDrawable(bd);
}
}, 100);
requestLayout();
}
}

Show title and snippet upon marker creation

I wish to add a marker to a googleMap with an editable title and snippet. The marker should appear when the user does a long click on the map and then the marker should appear showing a title of something like "click to edit".
The code is all up and running except that I can not figure out how to get the title to appear the moment the marker is created. I can only make it appear with a subsequent click on the marker. I can not see anything within MarkerOptions that allows me to do this. Did I miss something?

The option your looking for is not in MarkerOptions it is a function of the Marker itself. Here's a link to the related docs
marker.showInfoWindow();
To call this method you need to have the marker, or a reference to it. If you're doing this on creation it should be easy. Otherwise just store your makers in some collection - like a HashMap so they are easy to find - and you can display the info window whenever you want.

In case you want to display your marker's title and snippet in your own custom way - you may set it in the onMapReadyCallback.
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
mGoogleMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
#Override
public View getInfoWindow(Marker marker) {
return null;
}
#Override
public View getInfoContents(Marker marker) {
View view = getLayoutInflater().inflate(R.layout.marker_info, null);
TextView textViewTitle = (TextView) view.findViewById(R.id.marker_title);
textViewTitle.setText(marker.getTitle());
TextView textViewSnippet = (TextView) view.findViewById(R.id.marker_snippet);
textViewSnippet.setText(marker.getSnippet());
return view;
}
});
And here is my layout file for the same.
marker_info.xml.
<?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">
<TextView
android:id="#+id/marker_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:gravity="center"/>
<TextView
android:id="#+id/marker_snippet"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"/>

How to offset the balloon view in a marker in Google Map V2?

When I click a marker, appears a balloon. But there are too space between the marker and the balloon, so how I can reduce this distance?. It's like using the setBalloonBottomOffset method in the V1 Google Map.
My custom balloon is this class:
public class CustomInfoWindowAdapter implements InfoWindowAdapter {
private final View mWindow;
private final View mContents;
public CustomInfoWindowAdapter(Activity activity) {
LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mWindow = inflater.inflate(R.layout.ballon, null);
mContents = inflater.inflate(R.layout.ballon, null);
}
#Override
public View getInfoWindow(Marker marker) {
render(marker, mWindow);
return mWindow;
}
#Override
public View getInfoContents(Marker marker) {
render(marker, mContents);
return mContents;
}
private void render(Marker marker, View view) {
String title = marker.getTitle();
TextView titleUi = ((TextView) view.findViewById(R.id.txtTitle));
if (title != null) {
titleUi.setText(title);
} else {
titleUi.setText("");
}
String snippet = marker.getSnippet();
TextView snippetUi = ((TextView) view.findViewById(R.id.txtPlace));
if (snippet != null) {
snippetUi.setText(snippet);
} else {
snippetUi.setText("");
}
}
}
I show a marker like
marker.showInfoWindow();
My balloon xml is
<RelativeLayout
android:layout_width="250dp"
android:layout_height="75dp"
android:background="#drawable/ballon" >

Map Markers are 'anchored' by default to the middle of the bottom of your layout (i.e., anchor(0.5,1)).
You can change the anchor point by using MarkerOptions.anchor when you create your Marker.

Have you tried using negative bottom margin for your whole balloon layout? Like so:
<RelativeLayout
android:layout_width="250dp"
android:layout_height="75dp"
android:background="#drawable/ballon"
android:layout_marginBottom="-8dp" >
Probably won't work or cause content to be cut off at the bottom, but still worth trying as the simplest approach. Perhaps there's another way to trick GoogleMap class but it's hard to figure out not having the source code to the API.
Another tip: you probably don't need your getInfoContents() method – just return null there. This method will only be called if you return null from getInfoWindow() (see here) – to incorporate your content view into default info window, which is clearly not your goal since you want to move balloon around.
Consequently, you can also throw out mContents, it's totally redundant, just takes up mem for another copy of your inflated view hierarchy that never gets used.
Tell me if the margin thing works for you. We could probably also try to make use of something like ((View)mWindow.getParent()) later when the item is being displayed but that would be trickier so I sugget to just try the margin first.

This is an old question, the current API has a MarkerOptions.infoWindowAnchor method which may help.
