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); } @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; } }
Set your edittext withEditText et = (EditText) findViewById(R.id.myEditText); et.setFilters(new InputFilter[]{ new InputFilterMinMax("1", "12")});
android:inputType="number"
