I'm using InfoWindowAdapter for all the markers on my Map (Api v2). All the Markers are well visible..
The issue is that My Custom InfoWindow is having size about 500px * 300px. When I'm touching any Points on the Map its being set to Center of screen so the InfoWindow is being cropped from Top.. My requirement is to auto adjust as per Info Window Size.
Please have a look at snaps.
Override the default behaviour of OnMarkerClickListener.
- call
marker.showInfoWindow() - calculate position on which screen should be centered using
Projectionand position of the marker and animate camera to that position - return
true

I had the same issue, I tried the following perfectly working solution
mMap.setOnMarkerClickListener(new OnMarkerClickListener()
{
@Override
public boolean onMarkerClick(Marker marker)
{
int yMatrix = 200, xMatrix =40;
DisplayMetrics metrics1 = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics1);
switch(metrics1.densityDpi)
{
case DisplayMetrics.DENSITY_LOW:
yMatrix = 80;
xMatrix = 20;
break;
case DisplayMetrics.DENSITY_MEDIUM:
yMatrix = 100;
xMatrix = 25;
break;
case DisplayMetrics.DENSITY_HIGH:
yMatrix = 150;
xMatrix = 30;
break;
case DisplayMetrics.DENSITY_XHIGH:
yMatrix = 200;
xMatrix = 40;
break;
case DisplayMetrics.DENSITY_XXHIGH:
yMatrix = 200;
xMatrix = 50;
break;
}
Projection projection = mMap.getProjection();
LatLng latLng = marker.getPosition();
Point point = projection.toScreenLocation(latLng);
Point point2 = new Point(point.x+xMatrix,point.y-yMatrix);
LatLng point3 = projection.fromScreenLocation(point2);
CameraUpdate zoom1 = CameraUpdateFactory.newLatLng(point3);
mMap.animateCamera(zoom1);
marker.showInfoWindow();
return true;
}
});
check code below: i have used simple alertDialog you can use custom or whatever you want.
public class testclassmaps extends AbstractMapActivity {
private GoogleMap map;
private TextView text;
@Override
protected void onCreate(Bundle arg0) {
// TODO Auto-generated method stub
super.onCreate(arg0);
if (readyToGo()) {
setContentView(R.layout.showmaps);
text = (TextView) findViewById(R.id.editText1);
getSupportActionBar().setHomeButtonEnabled(true);
SupportMapFragment mapFrag = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
map = mapFrag.getMap();
// map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
addMarker(map, 23.0333, 72.6167, "Ahmedabad", "");
addMarker(map, 22.3000, 73.1900, "Baroda", "");
map.setOnMapClickListener(new OnMapClickListener() {
@Override
public void onMapClick(LatLng point) {
// TODO Auto-generated method stub
map.addMarker(new MarkerOptions().position(point).title(
point.toString()));
Log.e("TAP MAP---->", "" + point);
text.setText("" + point);
}
});
}
map.setOnMarkerClickListener(new OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker arg0) {
// TODO Auto-generated method stub
if (arg0.getTitle().equalsIgnoreCase("Ahmedabad")) {
new AlertDialog.Builder(testclassmaps.this)
.setTitle("Ahmedabad")
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(
DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
}
}).show();
}
if (arg0.getTitle().equalsIgnoreCase("Baroda")) {
new AlertDialog.Builder(testclassmaps.this)
.setTitle("Baroda")
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(
DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
}
}).show();
}
return false;
}
});
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
if (item.getItemId() == android.R.id.home) {
finish();
}
return super.onOptionsItemSelected(item);
}
private void addMarker(GoogleMap map, double lat, double lon,
String string, String string2) {
map.addMarker(new MarkerOptions().position(new LatLng(lat, lon))
.title(string).snippet(string2));
}
}
to hide info window use marker.hideInfoWindow(); inside marker click
if you don't want to use alertDialog then you can use custom layout for info window below way:
map.setInfoWindowAdapter(new InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker arg0) {
/*ContextThemeWrapper cw = new ContextThemeWrapper(
getApplicationContext(), R.style.Transparent);*/
// AlertDialog.Builder b = new AlertDialog.Builder(cw);
LayoutInflater inflater = (LayoutInflater) getApplicationContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater
.inflate(R.layout.custom_infowindow, null);
return layout;
}
@Override
public View getInfoContents(Marker arg0) {
return null;
}
});
I also faced same problem and after long time I got working solution, may be it also work for
public boolean onMarkerClick(Marker marker) {
//Please use fix height popup
float container_height = getResources().getDimension(R.dimen.DIP_300);
Projection projection = mGoogleMap.getProjection();
Point markerScreenPosition = projection.toScreenLocation(marker.getPosition());
Point pointHalfScreenAbove = new Point(markerScreenPosition.x,(int) (markerScreenPosition.y - (container_height / 2)));
LatLng aboveMarkerLatLng = projection.fromScreenLocation(pointHalfScreenAbove);
marker.showInfoWindow();
CameraUpdate center = CameraUpdateFactory.newLatLng(aboveMarkerLatLng);
mGoogleMap.moveCamera(center);
mGoogleMap.animateCamera(center);
marker.showInfoWindow();
return true;
}
