Center a ProgressBar in a Custom Dialog

Question

I have a custom dialog (inherited from android.app.Dialog) with no title or border. To this dialog I add a normal ProgressBar, and would like to center it in the dialog. The dialog itself has a background image that stretches for the full screen. Everything seems to work except that the progress bar is not getting centered in the dialog. It looks like this:

ProgBar Not Centered in Dialog

This is the code I have used within the customDialog class, to add the progress bar to the dialog:

ProgressBar progBar = new ProgressBar(context);

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
addContentView(progBar, layoutParams);

getWindow().setGravity(Gravity.CENTER);

Is there something I'm missing, or getting wrong?

@chintankhetiya, If there is minimal change in my existing code to correct it, I'll use that. If not, I'll try out your solution — Rajath, May 30 '13 at 11:33
@BasimSherif, I used RelativeLayout instead of LinearLayout, but I did not see any change — Rajath, May 30 '13 at 11:33

Try this..

    ProgressBar progBar = new ProgressBar(context);

    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    lp.addRule(RelativeLayout.CENTER_HORIZONTAL, progBar.getId());
    lp.addRule(RelativeLayout.CENTER_VERTICAL, progBar.getId());

    parentLayout.addView(progBar, lp);

This did not work. Btw, there is no addView for Dialog, so I used addContentView – Rajath May 30 '13 at 11:41

Try this,

      LinearLayout.LayoutParams ll = (LinearLayout.LayoutParams)b.getLayoutParams();    
ll.gravity = Gravity.CENTER;
progBar.setLayoutParams(ll);

Try my solution using Relative layout – Basim Sherif May 30 '13 at 11:48

Try this, Set layout hight and width FILL_PARENT

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
params.gravity = Gravity.CENTER;
progBar.setLayoutParams(params);
