I want to convert GBP 29.15* to just 29.15.
Can anyone please help?
I have already tried parsing to integer/float, substring etc. but getting an error.

Try this:
float f = Float.valueOf("GBP 29.15*".replaceAll("[^\\d.]+|\\.(?!\\d)", ""));
It removes all non-number characters and then finds the float value.

I've got many resources with names based on a pattern:
R.drawable.small_house_red
R.drawable.small_house_blue
R.drawable.big_house_black
R.drawable.small_tree_red
I've got 3 strings: size, type, color. I can put all required resources to map, and get them by concated string but is it possible to get them without manually entering all combinations to the map?

You can use this
int id = context.getResources().getIdentifier("imageNameAsString", "drawable", context.getPackageName());
