方法一
Timer与TimerTask(Java实现)
public class timerTask extends Activity{
private int recLen = 11;
private TextView txtView;
Timer timer = new Timer();
public void onCreate(Bundle savedInstanceState){
(savedInstanceState);
setContentView();
txtView = (TextView)findViewById();
(task, 1000, 1000); // timeTask
}
TimerTask task = new TimerTask() {
***@Override
public void run() {
runOnUiThread(new Runnable() { // UI thread
***@Override
public void run() {
recLen--;
(""+recLen);
if(recLen < 0){
();
();
}
}
});
}
};
}
方法二
TimerTask与Handler(不用Timer的改进型)
public class timerTask extends Activity{
private int recLen = 11;
private TextView txtView;
Timer timer = new Timer();
public void onCreate(Bundle savedInstanceState){
(savedInstanceState);
1
setContentView();
txtView = (TextView)findViewById();
(task, 1000, 1000); // timeTask
}
final Handler handler = new Handler(){
***@Override
public void handleMessage(Message msg){
switch () {
case 1:
(""+recLen);
if(recLen < 0){
();
