editText设置输入最大值（不是长度）

package com.myplas.q.common.view;import android.text.InputFilter;import android.text.Spanned;/** * 编写： 黄双 * 时间： 2017/6/121519. * 邮箱： [e-mail] */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 (Exception nfe) { }        return "";    }    private boolean isInRange(int a, int b, int c) {        return b > a ? c >= a && c <= b : c >= b && c <= a;    }}

用法：

mEditText = (EditText) view.findViewById(R.id.dialog_layout_modify_editText);     mEditText.setFilters(new InputFilter[]{ new InputFilterMinMax("1", "12")});
