Get background color of a Layout

This can only be accomplished in API 11+ if your background is a solid color.

int color = Color.TRANSPARENT;Drawable background = view.getBackground();if (background instanceof ColorDrawable)    color = ((ColorDrawable) background).getColor();

To get background color of a Layout:

LinearLayout lay = (LinearLayout) findViewById(R.id.lay1);ColorDrawable viewColor = (ColorDrawable) lay.getBackground();int colorId = viewColor.getColor();

If It is RelativeLayout then just find its id and use there object instead of LinearLayout.

ColorDrawable.getColor() will only work with API level above 11, so you can use this code to support it from API level 1. Use reflection below API level 11.

public static int getBackgroundColor(View view) {        Drawable drawable = view.getBackground();        if (drawable instanceof ColorDrawable) {            ColorDrawable colorDrawable = (ColorDrawable) drawable;            if (Build.VERSION.SDK_INT >= 11) {                return colorDrawable.getColor();            }            try {                Field field = colorDrawable.getClass().getDeclaredField("mState");                field.setAccessible(true);                Object object = field.get(colorDrawable);                field = object.getClass().getDeclaredField("mUseColor");                field.setAccessible(true);                return field.getInt(object);            } catch (NoSuchFieldException e) {                e.printStackTrace();            } catch (IllegalAccessException e) {                e.printStackTrace();            }        }        return 0;    }
