回答1:

You can use LatLngBounds. It has contains method which returns true when given LatLng is inside bounds. If you want to get current visible region I recommend reading: https://stackoverflow.com/a/14700745/759007 .

You should use Location APIs

yes you can using map.setOnMapClickListener which will return the latlng and you can use this where ever you need:

map.setOnMapClickListener(new OnMapClickListener() {
    @Override
    public void onMapClick(LatLng point) {
        // your code                    
    }    
}
