在Android应用程序启动中使用ProgressDialog

如何在应用程序启动期间显示进度对话框。我在 oncreate 方法中显示了一个进度对话框，但在启动应用程序时它没有显示。

我已经尝试了解释的解决方案上述问题。但它的工作并不完美。

这是我的代码：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.dash);

        progressDialog = ProgressDialog.show(this, "", "Loading...");

        //Run background UI thread
        Thread laucherThread = new Thread(new Runnable() {            
            public void run() {
                Looper.prepare(); //I had to include this to prevent force close error
                startService(new Intent(DroidChirp.this,ChirpService.class));
                doBindService();
                Log.e(MY_DEBUG_TAG, "Prepairing to close the dialog");
                runOnUiThread(new Runnable() {                    
                    public void run() {
                        progressDialog.dismiss();
                    }
                });
                Log.e(MY_DEBUG_TAG, "Closed the dialog");
            }
         });
        laucherThread.start();
    }

我需要做的是：

显示进度对话框，直到完成所有初始设置

我面临的问题：

ProgressDialog 是启动时不显示。
启动应用程序时出现延迟（有时显示空白）。
在完成初始设置之前会出现 ProgressDialog。

谁能建议我如何建立这个功能。它是一个表格布局，每个选项卡都有列表视图。

How can I show a progressDialog during the start up of an application. I have shown a progressDialog in the oncreate method and its not showing when launching the application.

I have gone through this:
ProgressDialog not showing until after function finishes

I have tried the solution explained for the above question. But its not working perfectly.

Here is my code:

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.dash);

        progressDialog = ProgressDialog.show(this, "", "Loading...");

        //Run background UI thread
        Thread laucherThread = new Thread(new Runnable() {            
            public void run() {
                Looper.prepare(); //I had to include this to prevent force close error
                startService(new Intent(DroidChirp.this,ChirpService.class));
                doBindService();
                Log.e(MY_DEBUG_TAG, "Prepairing to close the dialog");
                runOnUiThread(new Runnable() {                    
                    public void run() {
                        progressDialog.dismiss();
                    }
                });
                Log.e(MY_DEBUG_TAG, "Closed the dialog");
            }
         });
        laucherThread.start();
    }

What I need to do is:
