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());

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.

{Data:{Management:[{individual:{individual_Suffx:,individual_FName:XYZ,individual_LName:ABC,individual_Emplyee_Title:BOARD SECRETARY&PRESIDENT/CEO,individual_Directng_MName:MNO,individual_DOB:1960-05-21},individual_Tin:{},individual_NPI_Id:{},individual_OrgIndvdl:[{Ownrshp_MngngCntrl_EfctvDt:2009-11-30,Ownrshp_MngngCntrl_RoleCd:W},{Ownrshp_MngngCntrl_EfctvDt:2009-11-30,Ownrshp_MngngCntrl_RoleCd:10},{Ownrshp_MngngCntrl_EfctvDt:2009-11-30,Ownrshp_MngngCntrl_RoleCd:15}],Mngng_Mdcr:{}},{Mngng_Indvdl:{Mngng_Indvdl_FName:TIMOTHY,Mngng_Indvdl_LName:TOOLEY,Mngng_Indvdl_MName:C,Mngng_Indvdl_DOB:1958-07-02},Mngng_Tin:{},Mngng_NPI_Id:{},Mngng_OrgIndvdl:{OwnrshpIntrst_MngngCntrl_EfctvDt:2014-05-01,Ownrshp_MngngCntrl_RoleCd:W},Mngng_Mdcr:{}}}}
Not sure if this will cover all corner cases, but this regex should work for your example:
String json = ...
json = json.replaceAll("[^{}\\[\\]:,]+", "\"$0\"");

If I have an initialized array in Java and I want to do a method to one element in that array I would do
array[n].method();
but how do I do the same thing with an arraylist?
arraylist[n].method() gives me an error.
With Java use get method with ArrayList:
arraylist.get(n).method();

What is the best way to parse a String value that looks like this id#1 ...id#398, so I can get de number after the id# String in JAVA.
If id# is a fixed prefix in every ID, I would have used
stringValue.split("id#")[0]
