How to set the background color of the layout constant after it has been changed programmatically?

Such as if we change the background color by clicking the button and the code to change background color is: 

relativeLayout.setBackgroundColor(Color.parseColor("#03a9f4"));

It will change the background to blue. But it will turn to default white after switching the activities or closing the activities. I want the color to be constant after changing it. Can anyone help me?

You can get the last color you used in your designated View (let's call it view) and store it in SharedPreferences in onPause():

int lastColor = ((PaintDrawable) view.getBackground()).getPaint().getColor();
SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(getActivity);
pref.edit().putInt("last_color", lastColor).commit();

Then restore the color in onResume():

SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(getActivity);
int lastColor = pref.getInt("last_color",0);
view.setBackgroundColor(lastColor);

Persist the color (e.g. in SharedPreferences) and then set it everytime your View is created.
