Adding in code not working

[rajohns08]

When I add a ProgressWheel in code with:

ProgressWheel loadingDialog = new ProgressWheel(context);
loadingDialog.spin()

nothing happens.

me too, are you solve?

[rajohns08]

No, I just used the xml code

[brucewuu520]

i solve it, you must setLayoutParams with width and height

[rajohns08]

I tried:

ProgressWheel loadingWheel = new ProgressWheel(this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(60, 60);
loadingWheel.setLayoutParams(layoutParams);
loadingWheel.setBarColor(Color.GREEN);
loadingWheel.spin();

but it still doesn't work for me.

rajohns08 you have to add progresswheel to some view after that it can be visible.

        RelativeLayout.LayoutParams params = new   RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
        params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);

        progressWheel = new ProgressWheel(this);
        progressWheel.setBarColor(Color.GREEN);
        progressWheel.setLayoutParams(params);
        progressWheel.spin();

        rootView.addView(progressWheel);
