Re: [問題] Android的程式裡面加上倒數計時的功能

[givemepass (〆)]

借用一下XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:orientation="vertical" >
     <TextView
         android:text="TextView"
         android:id="@+id/timer"
                 android:layout_width="fill_parent"
                 android:layout_height="wrap_content"
                 android:textSize="25sp"
        />
</LinearLayout>

MyCount.java
import 省略...(按Ctrl+Shift+o就會自己產生)

public class MyCount extends Activity{
    TextView timeDisplay;
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.timer);
        timeDisplay = (TextView)findViewById(R.id.timer);
        mCountDownTimer.start();
    }

    private CountDownTimer mCountDownTimer = new CountdownTimer(30000, 1000) {

        public void onTick(long millisUntilFinished) {
            timeDisplay.setText("seconds remaining: "
                + millisUntilFinished/1000);
        }

        public void onFinish() {
            timeDisplay.setText("done!");
        }
    };
}

不過官網有小錯CountDownTimer 寫成 CountdownTimer
