Set Background color programmatically [duplicate]

Answer 1

If you save color code in the colors.xml which is under the values folder,then you should call the following:

root.setBackgroundColor(getResources().getColor(R.color.name));

name means you declare in the <color/> tag.

Answer 2

This must work:

you must use getResources().getColor(R.color.WHITE) to get the color resource, which you must add in the colors.xml resource file

View someView = findViewById(R.id.screen);

someView.setBackgroundColor(getResources().getColor(R.color.WHITE));

Answer 3

you need to use getResources() method, try to use following code

View someView = findViewById(R.id.screen);
View root = someView.getRootView();
root.setBackgroundColor(getResources().getColor(color.white)); 

Edit::

getResources.getColor() is deprecated so, use like below

 root.setBackgroundColor(ContextCompat.getColor(this, R.color.white)); 

Answer 4

You can use

 root.setBackgroundColor(0xFFFFFFFF);

or

 root.setBackgroundColor(Color.parseColor("#ffffff"));

Answer 5

I didn't understand your question ... what do you mean by "when i set every one of my colour"? try this (edit: "#fffff" in original answer changed to "#ffffff"

  yourView.setBackgroundColor(Color.parseColor("#ffffff"));

Answer 6

The previous answers are now deprecated, you need to use ContextCompat.getColor to retrieve the color properly:

root.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.white));
