Android Question

Is there a way to define a min and max value for EditText in Android?

I want to define a min and max value for an


For example: if any person tries to enter a month value in it, the value must be between 1-12.

I can do it by using
but I want to know if there is any other way to do it in layout file or elsewhere.

I don't want to limit character count. I want to limit the value. For example, if I limit month
w characters when I enter 12 it will accept it but if I enter 22 it mustn't accept it while I am entering.


First make this class :

package com.test;

import android.text.InputFilter;
import android.text.Spanned;

public class InputFilterMinMax implements InputFilter {

    private int min, max;

    public InputFilterMinMax(int min, int max) {
        this.min = min;
        this.max = max;

    public InputFilterMinMax(String min, String max) {
        this.min = Integer.parseInt(min);
        this.max = Integer.parseInt(max);

    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {   
        try {
            int input = Integer.parseInt(dest.toString() + source.toString());
            if (isInRange(min, max, input))
                return null;
        } catch (NumberFormatException nfe) { }     
        return "";

    private boolean isInRange(int a, int b, int c) {
        return b > a ? c >= a && c <= b : c >= b && c <= a;

Then use this from your Activity :

EditText et = (EditText) findViewById(;
et.setFilters(new InputFilter[]{ new InputFilterMinMax("1", "12")});

This will allow user to enter values from 1 to 12 only.


Set your edittext with android:inputType="number".
