Question

这是对的吗？我正在修改github的源代码：USB CHARGE COMMANDER 当电池电量从20％下降时，它将充电当面糊达到80时，它不会倒数计时器是每5分钟做一次的我设置20000仅用于测试

    boolean startcountdown=true;
    do{
         new CountDownTimer(20000, 1000) {

        Intent intent  = _context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));   
        int    level   = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);
        int    scale   = intent.getIntExtra(BatteryManager.EXTRA_SCALE, 100);
        int    percent = (level*100)/scale;

        public void onTick(long millisUntilFinished) {}

        public void onFinish() {
                if(percent <= 20){
                        _iIsCharging = 1;
                }
                else if (percent >=80){
                        _iIsCharging = 0;
                }
                else{
                        _iIsCharging = 1;
                }
            }
        }.start();
        }while(startcountdown);

Answer 1

这个do / while循环无法结束，此刻它是一个无限循环。布尔＆＃34; startcountdown＆＃34;需要一些方法才能最终达到FALSE的价值。例如

if (_iIsCharging == 0) {
    startcountdown = false;
}

我的do循环代码是否正确？
