You can used two way.

First Way:

Set android:inputType="textCapSentences" on your EditText.

When user enter the number you have to used text watcher and change small to capital letter.

edittext.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {            

    }
        @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                    int arg3) {             
    }
    @Override
    public void afterTextChanged(Editable et) {
          String s=et.toString();
      if(!s.equals(s.toUpperCase()))
      {
         s=s.toUpperCase();
         edittext.setText(s);
         edittext.setSelection(edittext.length()); //fix reverse texting
      }
    }
});
