问题描述

我正在做一个小测验为Android，我想在有限的时间来回答每一个问题。所以，我想下，从例如，5比0（秒）倒计时的答案显示进度条。而当它达到零我想要做一些东西。我有测验和一切工作，我只是想添加进度。

I'm making a quiz for Android and I want a limited time to answer every question. So I want to display a ProgressBar under the answers that counts down from, for example, 5 to 0 (seconds). And when it reaches zero I want to do some stuff. I have the quiz and everything working, I just want to add the ProgressBar.

您可以使用Android的倒数计时。

you can use countdown timer in android .

下面是一个例子，你可以参考点击此处

Here is one Example you can Refer Click Here

您可以在活动中使用下面的进度条。

you can use below ProgressBar in your Activity.

   <ProgressBar 
    android:id="@+id/progressbar"
    style="@android:style/Widget.ProgressBar.Horizontal"
    android:max="5"
    android:progress="0"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/bottom_header_relativelayout"
    />

使用 CountDownTimer 像下面code在你的活动。

Use CountDownTimer Like Below code in your Activity.

ProgressBar mProgressBar;
CountDownTimer mCountDownTimer;
int i=0;

mProgressBar=(ProgressBar)findViewById(R.id.progressbar);
mProgressBar.setProgress(i);
   mCountDownTimer=new CountDownTimer(5000,1000) {

        @Override
        public void onTick(long millisUntilFinished) {
            Log.v("Log_tag", "Tick of Progress"+ i+ millisUntilFinished);
            i++;
            mProgressBar.setProgress(i);

        }

        @Override
        public void onFinish() {
        //Do what you want 
            i++;
            mProgressBar.setProgress(i);
        }
    };
    mCountDownTimer.start();
