Android开发(五)——计时器
发送验证码后倒计时,Android自带计时器CountDownTimer,重写自己的计时器以实现跟新View的效果。
package com.lgaoxiao.widget; import android.os.CountDownTimer; import android.widget.TextView; /** * TextView的计时器 * @author TimZhang * */ public class MyCountTimer extends CountDownTimer { private TextView btn; private int normalColor,timingColor; private String normalText; /** * @param millisInFuture * @param countDownInterval * @param v TextView * @param nColor Normal Color * @param tColor Timing Color */ public MyCountTimer(long millisInFuture, long countDownInterval,TextView v,int nColor,int tColor) { super(millisInFuture, countDownInterval); this.btn = v; this.normalColor = nColor; this.timingColor = tColor; this.normalText = v.getText().toString(); } @Override public void onTick(long millisUntilFinished) { btn.setBackgroundColor(timingColor); btn.setEnabled(false); btn.setText(millisUntilFinished / 1000 + "s"); } @Override public void onFinish() { btn.setEnabled(true); btn.setBackgroundColor(normalColor); btn.setText(normalText); } }
