Show indefinite progress cycle on the Activity

Question

I'd like my application to show the indefinite progress bar (you know, the cycle) into the Activity's layout, just like the youtube Application. How could I do that? Thanks.

Hi you can use setProgressBarIndeterminateVisibility(boolean) to show indefinite progress bar.Here is the sample code:

private Button buttonUpStartUpload = null;
        private boolean mToggleIndeterminate = false;



@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);

        setContentView(R.layout.lyt_upload_main);
        setProgressBarIndeterminateVisibility(mToggleIndeterminate);

        buttonUpStartUpload = (Button) findViewById(R.id.buttonUpStartUpload);

        buttonUpStartUpload.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                UploadingAsyncTask uploadingAsyncTask = new UploadingAsyncTask();
                uploadingAsyncTask.execute("temp","doinback","returnparam");
                }
        });


    }//onCreate Ends

    @Override
    protected void onStart() {
        // TODO Auto-generated method stub
        super.onStart();

    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
    }

    public class UploadingAsyncTask extends AsyncTask<String, String, String>{

        Uploader uploader = new Uploader();
        ProgressDialog progDialogUpload = null;
        int imageIndex = 1;
        @Override
        protected void onPreExecute() {
            // TODO Auto-generated method stub
            super.onPreExecute();
            mToggleIndeterminate = !mToggleIndeterminate;
            setProgressBarIndeterminateVisibility(mToggleIndeterminate);
        }

        @Override
        protected String doInBackground(String... params) {
            // TODO Auto-generated method stub

            publishProgress("Finish","3");
            return "success";
        }

        @Override
        protected void onProgressUpdate(String... values) {
            // TODO Auto-generated method stub
            super.onProgressUpdate(values);
            if(values[0] == "Finish"){
                imageIndex++;
            }
            }

        @Override
        protected void onPostExecute(String result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            if(result.equalsIgnoreCase("success") || result == "success"){
                mToggleIndeterminate = !mToggleIndeterminate;
                setProgressBarIndeterminateVisibility(mToggleIndeterminate);
            }
        }       

    }//UploadingAsyncTask ends
