Restricting text editing in android with decimal point

I have a question about the limit number in editText. I want the user to only be able to enter a number between 1-70. When a user wants to bet 70.01 or more, I want them not to be allowed. Only two decimal places are allowed. The total length is 5 characters, including the period.

I can limit before and after the decimal. and also limit 70, but user can enter 70.99 (not sure why) in a text editor that I want to block. my validation works when user enters 71 or more

this is the constructor i im using in the fragment

     txtno.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(Integer.parseInt(getString(R.string.length)),2,txtno)});

      

        
        
        
      

    

this is the value after and before the decimal number

@Override
public CharSequence filter(CharSequence source, int start, int end,Spanned dest,    int dstart, int dend) {

    mTextView.setKeyListener(DigitsKeyListener.getInstance(true,true));
    String etText = mTextView.getText().toString();
    String temp = mTextView.getText() + source.toString();
    if (temp.equals(".")) {

        return "0.";
    } else if (temp.toString().indexOf(".") == -1) {

        // no decimal point placed yet
        if (temp.length() > mMyint) {

            return "";
        }
    } else {

        int dotPosition;
        int cursorPositon = mTextView.getSelectionStart();

        if (etText.indexOf(".") == -1) {

            dotPosition = temp.indexOf(".");
        } else {

            dotPosition = etText.indexOf(".");
        }
        if (cursorPositon <= dotPosition) {

            String beforeDot = etText.substring(0, dotPosition);
            if (beforeDot.length() < mMyint) {

                    return source;
            } else {

                if (source.toString().equalsIgnoreCase(".")) {

                    return source;
                    } else {

                    return "";
                    }
            }
        } else {

            temp = temp.substring(temp.indexOf(".") + 1);
            if (temp.length() > mMydec) {

                return "";
            }
        }
    }
    return null;
}

      

        
        
        
      

    

& this is a textWatcher for a limit of 70

public void afterTextChanged(Editable s) {

    try{

        if(Integer.parseInt(s.toString())>70){

            s.replace(0, s.length(), s.toString());
        }
    }catch(Exception e){}

      

        
        
        
      

    

Thanks in advance.
