You should create an InputFilter for EditText. Visit this link

First create a class implementing InputFilter:

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 {
            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 set Min and Max values to bound each edittext:

EditText et = (EditText) findViewById(R.id.your_edittext);
et.setFilters(new InputFilter[]{ new InputFilterMinMax("1", "100");

Note that you can use other EditText's value to set other Editbox's MaxValue (If you need)

on your submit button handler you can check if the value of min is greater than the value of max and show the user a suitable message

int maxVal = Integer.valueOf(max.getText().toString().trim());
int minVal = Integer.valueOf(min.getText().toString().trim());
if (minVal > maxVal){
 ...
}
