Question

我对read子有问题。我不敢肯定这里发生的情况。我的理解是,在长期活动结束之前,进展方言已告终,但情况并非如此。我希望这一长期活动能够开始、结束、解职,然后开始新的活动。

 final ProgressDialog spinnerDialog = ProgressDialog.show(  
                MainScreen.this, "",  
                "Waiting for accurate (> 10 meters) GPS coordinates...Please wait. ", true);  
            new Thread(new Runnable() {  
                public void run() {  
                    //Do something that takes a while
                    spinnerDialog.dismiss();  
                    return;  
                }  
            }).start();

              Intent tvi = new Intent();
              tvi.setClass(getInstance(), TabbedView.class);
              startActivity(tvi);

应在主线上开展新的活动。但是,在新版面开始后,仅仅写这部法典,就能够保证你掌握了你创造你意图所需的一切信息。我建议使用手稿

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    progress = (ProgressBar) findViewById(R.id.progressBar1);
    handler = new Handler();
    startprogress();

public void startProgress(View view) {
    // Do something long
    Runnable runnable = new Runnable() {
        @Override
        public void run() {
            //do long stuff (like getting info for intent)
            handler.post(new Runnable() {
            @Override
            public void run() {
                //make new intent
                //start new activity with intent you just made
            iii
        iii);
        iii
    iii
    iii;
    new Thread(runnable).start();
