Question

I am new to Android. In my application I want to add an process bar(an image), this should indicate that something is in process and after completion hide this precess bar.

As if i add user detail, On click on add button this process bar should be displayed.

How can i do it, please suggest.

Thanks.

Code I used:

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

                new Thread() {

                public void run() {

                try{

                sleep(10000);

                } catch (Exception e) {

                Log.e("tag", e.getMessage());

                }

                progressDialog.dismiss();
                }

            }.start();

The problem with it is , it is hardcoded sleep(10000) whereas what i want is it to be dependent on how much time my process takes to add or fetch data.

I am not getting where to put code which is executing on onclick of button.

I hope you got my point

Thanks again.

For that you can use either ProgressDialog or ProgressBar.

Now, To display Progress bar and during that perform task in background, you should implement AsyncTask.

1. In onPreExecute() method, display the ProgressBar or make it visible again like: progressbar.setVisibility(View.VISIBLE);
2. In doInBackground() method, perform the background task, i.e. add user detail in your case
3. In onPostExecute() method, just hide the ProgressBar using the progressbar.setVisibility(View.INVISIBLE);
