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

Question

I want to define a min and max value for an EditText.

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

If you need range with negative numbers like -90:90, you can use this solution.

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);
}

@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    try {
        String stringInput = dest.toString() + source.toString();
        int value;
        if (stringInput.length() == 1 && stringInput.charAt(0) == '-') {
            value = -1;
        } else {
            value = Integer.parseInt(stringInput);
        }
        if (isInRange(min, max, value))
            return null;
    } catch (NumberFormatException nfe) {
    }
    return "";
}

private boolean isInRange(int min, int max, int value) {
    return max > min ? value >= min && value <= max : value >= max && value <= min;
}
}
