I checked Android: How do you create an EditText feild in java class

and How to create EditText numeric (signed and unsigned decimal) from java code

Answer 1

This is easy from XML.
This is how we can do this java file.

EditText et = new EditText(context);                     
// setting input type filter        
et.setInputType(InputType.TYPE_CLASS_NUMBER);                    
// setting input max length
InputFilter maxLengthFilter = new InputFilter.LengthFilter(inp.getLength());
et.setFilters((new InputFilter[]{ maxLengthFilter }));
// settin it to password 
et.setTransformationMethod(PasswordTransformationMethod.getInstance());
