Question

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.

Answer 1

use the AsychTask class for just write your code into the inBackground() method and show the progress using onUpdateProgress() and dismiss on onPostExecute()
