This is an example for updating rating on a dialog box.

Activity Code:

Button rankBtn = (Button) findViewById(R.id.rank_button);
rankBtn.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {
        rankDialog = new Dialog(MyActivity.this, R.style.FullHeightDialog);
        rankDialog.setContentView(R.layout.rank_dialog);
        rankDialog.setCancelable(true);
        ratingBar = (RatingBar)rankDialog.findViewById(R.id.dialog_ratingbar);
        ratingBar.setRating(userRankValue);
        
        TextView text = (TextView) rankDialog.findViewById(R.id.rank_dialog_text1);
        text.setText(name);
 
        Button updateButton = (Button) rankDialog.findViewById(R.id.rank_dialog_button);
        updateButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                rankDialog.dismiss();
            }
        });
        //now that the dialog is set up, it's time to show it    
        rankDialog.show();                
    }
});
