Limit the number of non decimal digits in an edittext

Question

I have an edittext in which I have to enter only digits below 10000. 9999.99 is a valid entry but 10000 is not. Is there any way to limit the number of digits in the mantessa part

add this line android:numeric="integer" and take a TextWatcher check total value< 10000

<EditText android:numeric="integer"... />

edittext.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub  
        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub
          float final =Float.valueOf(s.toString());
          if(final<10000)
             //accept
          else
             //reject
        }
    });

You can use InputFilter in your edittext:
