You can Use InputFilter for restricting the number of characters in EditView programmatically as:

InputFilter[] FilterArray = new InputFilter[1];
FilterArray[0] = new InputFilter.LengthFilter(10);
your_edittext.setFilters(FilterArray);

for more help you can see this tutorial for restricting number of characters in EditView:

Answer 4

I would implement a filter:

InputFilter filter = new InputFilter() {

   @Override
   public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
      if (source.length > 10){
       //cancel the edit or whatever
      }
   }
};
EditText editText = (EditText) findViewById(R.id.rg);
editText.setFilters(new InputFilter[] {filter});
