我如何在android工作室中写作:如果条件为真至少5秒，那么做点什么

Question

下面是我当前的代码。然而，问题是图像一直在闪烁

CountDownTimer mCountDownTimer  = new CountDownTimer(5000, 1000) {
public void onTick(long millisUntilFinished){}
public void onFinish() {
image1.setVisibility(View.VISIBLE);
}
};
if (dan > -1) {
mCountDownTimer.start();
} else {
image1.setVisibility(View.GONE);
mCountDownTimer.cancel();
}

Answer 1

var isFalseAfterDelay = false
if (!isFalseAfterDelay) {
isFalseAfterDelay = true//this will be true till 5 sec then it will false
Handler().postDelayed( {
isFalseAfterDelay = false
},5000)// this will delay your operation for 5 sec
}
