单击按钮时显示进度对话框

我在我的应用程序中使用以下代码。

    Button button = new Button(this);
    button.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {

                    ProgressDialog pd = new ProgressDialog(v.getContext());
                    pd.setTitle("Please wait.......");
                    pd.show();
                    // some task which will take minimum  2 or 3 seconds
                    // e.g. parsing XML file
                    pd.dismiss();
                }
            });

我认为根据上面的代码，当我单击按钮时，进度对话框必须显示在屏幕上，但它没有显示。为什么我不知道。

但是，如果我删除 pd.dismiss() 它的显示，那么也仅在按钮释放后。

如果我也将任何无限循环代替我的任务，它不显示进度对话框。

我的代码正确吗？如果有人知道我的要求的解决方案，请回复此帖子。

谢谢。

I am using the below code in my application.

    Button button = new Button(this);
    button.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {

                    ProgressDialog pd = new ProgressDialog(v.getContext());
                    pd.setTitle("Please wait.......");
                    pd.show();
                    // some task which will take minimum  2 or 3 seconds
                    // e.g. parsing XML file
                    pd.dismiss();
                }
            });

I thought according to above code, when i click the button the progress dialog has to be displayed on screen, but its not displaying. Why i don't know.

But if i remove pd.dismiss() its displaying, that also after button released only.

If i put any infinite loop in place of my task also, its not displaying progress dialog.

Is my code correct ? If anybody knows solution to my requirement please reply to this post.

Thanks.
