Android自定义控件——获取验证码倒计时

目前为止，有很多地方都需要绑定用户手机号，发送短信，比如说找回密码，注册或者登陆，这些控件都是很常用的，不需要每次使用的时候都重新写一个，这样比较麻烦，也浪费时间。本人自定义了一些控件。

废话不多说，接下来就直奔主题，开始撸代码吧。

属性：

<declare-styleable name="MLabelEditView">        <attr name="m_lev_label" format="string" />        <attr name="m_lev_edit_hint" format="string" />        <attr name="m_lev_count" format="string" />        <attr name="m_lev_edit" format="string" />        <attr name="m_lev_count_visibilty">            <enum name="visiable" value="0" />            <enum name="gone" value="1" />            <enum name="invisiable" value="2" />        </attr>        <attr name="m_lev_label_visibilty">            <enum name="visiable" value="0" />            <enum name="gone" value="1" />            <enum name="invisiable" value="2" />        </attr>        <attr name="m_lev_count_color" format="reference" />        <attr name="m_lev_ems" format="integer" />    </declare-styleable>

当然还需要倒计时：

package com.morse.library.utils;import android.content.Context;import android.os.CountDownTimer;import android.view.View;import android.widget.Button;import android.widget.TextView;/** * 倒计时工具类 * * @company:大后天 * @Author:曾明 * @Time:2017/8/23 21:06 * @Description: */public class CountDown extends CountDownTimer {    private Context mContext;    private View mView;    private int mColor;    private int mText;    private int mFinishText;    /**     * 倒计时     *     * @param context     * @param millisInFuture    倒计时时长     * @param countDownInterval 倒计时时间间隔     * @param view              倒计时控件     * @param color             控件颜色     * @param text              倒计时开始之后显示的文本     * @param finishText        倒计时结束之后显示的文本     */    public CountDown(Context context, long millisInFuture, long countDownInterval, View view, int color, int text, int finishText) {        super(millisInFuture, countDownInterval);        mContext = context;        mView = view;        mColor = color;        mText = text;        mFinishText = finishText;    }    public CountDown(Context context, long millisInFuture, long countDownInterval, View view, int text, int finishText) {        this(context, millisInFuture, countDownInterval, view, -1, text, finishText);    }    @Override    public void onTick(long millisUntilFinished) {        if (mView instanceof TextView || mView instanceof Button) {            mView.setClickable(false);            if (mColor > 0) {                mView.setBackgroundColor(mContext.getResources().getColor(mColor));            }            if (mText <= 0) {                return;            }            mView.setTag(mContext.getResources().getString(mText, millisUntilFinished / 1000));        }    }    @Override    public void onFinish() {        if (mView instanceof TextView || mView instanceof Button) {            mView.setClickable(true);            if (mColor > 0) {                mView.setBackgroundColor(mContext.getResources().getColor(mColor));            }            if (mFinishText <= 0) {                return;            }            mView.setTag(mContext.getResources().getString(mFinishText));        }    }}

注释已经很详细，具体的我就不再啰嗦了。希望对各位有所帮助。
