Android ProgressBar countdown


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.

Thanks in advance!


Solution

  • you can use countdown timer in android .

    Here is one Example you can Refer Click Here

    you can use below ProgressBar in your Activity.

       <ProgressBar 
        android:id="@+id/progressbar"
        style="@android:style/Widget.ProgressBar.Horizontal"
        android:max="100"
        android:progress="0"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/bottom_header_relativelayout"
        />
    

    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((int)i*100/(5000/1000));
    
            }
    
            @Override
            public void onFinish() {
            //Do what you want 
                i++;
                mProgressBar.setProgress(100);
            }
        };
        mCountDownTimer.start();
