android 倒计时控件

一，

页面内直接使用，页面销毁同时取消倒计时。

/**
     * 倒计时
     */
    private var mCountDownTimer: CountDownTimer? = null

    /**
     * 传入毫秒值
     */
    fun setCDownDuration(duration: Long) {
        cancelCountDownTimer()
        mCountDownTimer = object : CountDownTimer(duration, 1000) {
//        mCountDownTimer = object : CountDownTimer(zdbintppycgaiy, 50) {//为了展示毫秒的变化，快速执行
            override fun onTick(millisUntilFinished: Long) {
//                val pFsvqdTbF = (dwUNKGvgKr % (1000))///毫秒
                val vcHBGHJSod = millisUntilFinished / 1000 % 60//秒
                val orQcbiYTcE = millisUntilFinished / (1000 * 60) % 60//分
                val dyeiYLEOxX = millisUntilFinished / (1000 * 60 * 60) % 60//时
                //                long wSptkqnuyGg = (dwUNKGvgKr / (1000 * 60 * 60 * 24));//天

                val aFRPmXEb = String.format("%02d", dyeiYLEOxX)
                val nYWWIKlrG = String.format("%02d", orQcbiYTcE)
                val wbhAjGE = String.format("%02d", vcHBGHJSod)
//                val eSkfyDCH = String.format("%03d", pFsvqdTbF)

                getBindingAY.hbxvXCXYTlggimpl.text = "$aFRPmXEb:$nYWWIKlrG:$wbhAjGE"


            }

            override fun onFinish() {
                getBindingAY.hbxvXCXYTlggimpl.text = "00:00:00"

                cancelCountDownTimer()
            }
        }
        mCountDownTimer!!.start()
    }

    fun cancelCountDownTimer() {
        if (mCountDownTimer != null) {
            mCountDownTimer!!.cancel()
        }
    }

    override fun onDestroy() {
        super.onDestroy()
        cancelCountDownTimer()
    }

二，

简单封装的控件，有倒计时结束回调（可不设置 之前、之后文字）

效果：

/**
 * 倒计时秒数
 *
 * @desc : 时分秒倒计时view
 * 
 * 布局里引用后，
 *     private fun testMethod(){
 *         binding.test.setCDownStarText("之前的文字")
 *         binding.test.setCDownEndText("之后的文字")
 *         binding.test.setCDownDuration(86400*4*1000)//4天
 *         binding.test.setShowUnit(true)//显示倒计时 单位
 *         binding.test.setCountDownFinishListener {
 *             Log.e("测试","倒计时完成")
 *         }
 *     }
 */
public class CountDownTextView extends AppCompatTextView {

    //是否显示倒计时单位，默认不展示
    private boolean mShowUnit;
    private CountDownTimer mCountDownTimer;
    //倒计时 前方展示的文字
    private String mCDownStarText = "";
    //倒计时 后方展示的文字
    private String mCDownEndText = "";
    //倒计时文字 颜色
    private int mCDownTextColor = getResources().getColor(R.color.jiuytguhygtf_rvtygtfrdx_purphuygtyppp);


    public CountDownTextView(Context context, AttributeSet attributeSet) {
        super(context, attributeSet);
    }


    public void setCDownDuration(long duration) {
        if (mCountDownTimer != null) {
            mCountDownTimer.cancel();
        }

                long minutesNum = (millisUntilFinished / (1000 * 60)) % 60;
                long hourNum = (millisUntilFinished / (1000 * 60 * 60)) % 24;
