Create and show ProgressBar programmatically

Question

I have created a ProgressBar programmatically as below in my activity. How do I make it show?

progressBar = new ProgressBar(activity, null, android.R.attr.progressBarStyleSmall);

Answer 1

You can try this code for adding progressBar programaticlly to your layout.

RelativeLayout layout = new RelativeLayout(this);
ProgressBar progressBar = new ProgressBar(YourActivity.this,null,android.R.attr.progressBarStyleLarge);
progressBar.setIndeterminate(true);
progressBar.setVisibility(View.VISIBLE);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(100,100);
params.addRule(RelativeLayout.CENTER_IN_PARENT);
layout.addView(progressBar,params);

setContentView(layout);

Answer 2

progressBar is a widget (view). You need to add to viewgroup.

You can use ProgressDialog to show progress loading Example:

ProgressDialog proDialog = ProgressDialog.show(this, "title", "message");
