Android change theme of new ProgressBar()

Question

I want to change the theme of just ONE ProgressBar so changing the global theme is not an option.

Existing code:

ProgressBar pb = new ProgressBar(context);
((LinearLayout) v).addView(pb,0);

It works, no errors, but uses the default them. How can I change that?

Answer 1

Use a different constructor to set the style:

ProgressBar loadingProgressBar = new ProgressBar(this, null, android.R.attr.progressBarStyleHorizontal);

And if you want to customize the actual appearance (colors, size, etc.) use this:

loadingProgressBar.setProgressDrawable(getResources().getDrawable(R.drawable.mycustomtheme));
