Set Background color programmatically [duplicate]

Question

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"));

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)); 

You can use

 root.setBackgroundColor(0xFFFFFFFF);

or

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

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));

If you just want to use some of the predefined Android colors, you can use Color.COLOR (where COLOR is BLACK, WHITE, RED, etc.):

myView.setBackgroundColor(Color.GREEN);

Otherwise you can do as others have suggested with

myView.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.myCustomGreen));

I don't recommend using a hex color directly. You should keep all of your custom colors in colors.xml.
