how to make Google Mapview change to fullscreen from a smaller mapview?

Question

I have a Google mapview in the corner of the screen. I want to add an event that makes it go fullscreen with a button on the map interface, and then small screen again with the same button. Any ideas??

Android v4.0.4 Google Map API V2

Answer 1

You could do this by 2 way:

1. create a new Activity that on the press of a button will start of and will include a full screen map. in this activity create the same button that will bring you back to your original Activity.

2. you can programaticly change the Layout width a length of you MapFragment in the same window.

second option will be better as you would avoid the screen flickering of new activity loading.

UPDATE:

regarding the second option here is a code i wrote to enlarge map onClick of the map see if this helps you:

 @Override
 public void onMapClick(LatLng point) 
{
    LinearLayout mapFrameLayout = (LinearLayout)findViewById(R.id.mapFrameLayout);

    if (!isMapOpen)     
    {
        LinearLayout.LayoutParams fullMapParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
        if (!isDetailsOpen)
        {
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.hide(closedDetailsFragment).commit();
            mapFrameLayout.setLayoutParams(fullMapParams);
            isMapOpen = true;
            isDetailsOpenWhenOpenedMap = false;
        }
        else
        {
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.hide(openedDetailsFragment).commit();
            mapFrameLayout.setLayoutParams(fullMapParams);
            isMapOpen = true;
            isDetailsOpenWhenOpenedMap = true;
        }
    }
    else
    {
        LinearLayout.LayoutParams defaultMapparams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 280);
        mapFrameLayout.setLayoutParams(defaultMapparams);
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        if (isDetailsOpenWhenOpenedMap)
        {
            fragmentTransaction.show(openedDetailsFragment).commit();               
        }
        else
        {
            fragmentTransaction.show(closedDetailsFragment).commit();
        }
        isMapOpen = false;
    }
}

as you see i change the size of the FrameLayout where the map sits, you can put in the same layout your button and place it on the right|top corner for example. when your map will stretch the button will still be at the same right|top corner.
