如何删除位于t.start();

的错误

public class Timer extends Fragment {

TextView tv1;
Thread t1;
Date d1;
int hour,min,sec;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    final View android = inflater.inflate(R.layout.timer, container, false);
    //((TextView)android.findViewById(R.id.textView)).setText("Timer");
    return android;

  //tv1 = (TextView)findviewById(R.id.textView1);

t1 = new Thread(){
    public void run(){
        try{
            while (!isInterrupted()) {
                Thread.sleep(1000);
                runOnUiThread(new Runnable() {
                  @Override
                  public void run() {
                  d1 = new Date();
                  hour = d1.getHours();
                  min = d1.getMinutes();
                  sec = d1.getSeconds();
                  String displaytime =  hour+":"+min+":"+sec ;
                //  tv1.setText(displaytime);
                ((TextView)android.findViewById(R.id.textView1)).setText(displaytime);
                         }});//runOnUiThread ends here
              }//While ends here
        }catch (InterruptedException e) {
        }//Catch ends here
    }

/ * ECLIPSE在下面显示错误t1.start(); * /

    t1.start();

    private void runOnUiThread(Runnable runnable) {
        // TODO Auto-generated method stub
    }
};//Thread Ends here
}//Oncreate




}   //Fragment

您正在return声明之后制作该帖子。

将return android;行移至线程结束后。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    final View android = inflater.inflate(R.layout.timer, container, false);

t1 = new Thread(){
    public void run(){
        try{
            while (!isInterrupted()) {
                Thread.sleep(1000);
                runOnUiThread(new Runnable() {
                  @Override
                  public void run() {
                  d1 = new Date();
                  hour = d1.getHours();
                  min = d1.getMinutes();
                  sec = d1.getSeconds();
                  String displaytime =  hour+":"+min+":"+sec ;
                //  tv1.setText(displaytime);
                ((TextView)android.findViewById(R.id.textView1)).setText(displaytime);
                         }});//runOnUiThread ends here
              }//While ends here
        }catch (InterruptedException e) {
        }//Catch ends here
    }
/* ECLIPSE IS SHOWING ERROR IN BELOW t1.start(); */

    t1.start();

    private void runOnUiThread(Runnable runnable) {
        // TODO Auto-generated method stub
    }
};//Thread Ends here 


return android;
}//Oncreate

} //Fragment

请发布错误eclipse显示。并声明“返回android;”应该是oncreateview方法的最后一行。
