public class MapsActivity extends FragmentActivity
{
Googlemap gm;

gm = ((SupportMapFragment) (getSupportFragmentManager()
            .findFragmentById(R.id.map))).getMap();
gm.setMapType(GoogleMap.MAP_TYPE_NORMAL);
gm.setOnInfoWindowClickListener(this);
@Override
public void onInfoWindowClick(Marker marker) {
    String a=marker.getTitle();
   // how to display this title in same screen below with dragging up and down when map marker been tap

}
    }

Please help me to solve this issue.Thanks in advance.

implement this method instead of infoWindowClick

gm.setOnMarkerClickListener(new OnMarkerClickListener() {

    @Override
    public boolean onMarkerClick(Marker arg0) {
    // TODO Auto-generated method stub
            String title = "Any Thing You want";
                marker.setTitle(title);
                textView.setText("title");
        return true;
    }
});

You have to create hidden layout for it. Create one layout as per your need and do it GONE by default. But when you click like below and inflate that layout in you onClick method:

    gm.setOnInfoWindowClickListener(this);
    @Override
    public void onInfoWindowClick(Marker marker) {
        String a=marker.getTitle();
        LayoutInflater inflater;
        inflater = LayoutInflater.from(context);
        View view;
        view = adapterInflater.inflate(R.layout.adapter_add_event, null);
       // how to display this title in same screen below with dragging up and down when map marker been tap

}

And visible this layout, do findViewById and make it visible.

or.. If your marker is draggable, use the following snippet

        map.setOnMarkerDragListener(new GoogleMap.OnMarkerDragListener() {

        @Override
        public void onMarkerDragEnd(Marker marker) {
            marker.setSnippet("Your Text");
            map.animateCamera(CameraUpdateFactory.newLatLng(marker.getPosition()));

        }

    });
