How to retrieve a view's background color and compare it to a color resource

I'm trying to compare whether the background color of one of my views is equal to a color resource I created and haven't found anything that works.

I'm willing to use any method, whether converting to HEX or String or Int, as long as it works. Here's an example of my current method.

I set the background color of a view with:

chosenColor.setBackgroundColor(getResources().getColor(R.color.tag_pink));


When I retrieve it using this method:

ColorDrawable chosenColorBox = (ColorDrawable) chosenColor.getBackground();
int colorId = chosenColorBox.getColor();

colorId == `-611329`


Using
Integer.toString
on
R.color.tag_pink
shows the value as
2130968581
which obviously can't be compared in an
if
statement" with the retrieved value.

What's the best way to do this so I don't have to resort to hard-coding the individual values, which prevents me from adjusting the color resources?

Answer

Try to compare the color to Context.getResources().getColor(R.color.tag_pink) instead of the resource's ID (which is not the color!). The returned value represents the color in the form of 0xAARRGGBB.
