我试过这样的事,但我坚持了下来:
TypedValue typedValue = new TypedValue();
if (this.parentActivity.getTheme().resolveAttribute(android.R.attr.windowBackground, typedValue, true))
{
// how to get color?
}

您可以通过以下方式从当前主题中获取背景颜色(或Drawable):
TypedValue a = new TypedValue();
getTheme().resolveAttribute(android.R.attr.windowBackground, a, true);
if (a.type >= TypedValue.TYPE_FIRST_COLOR_INT && a.type <= TypedValue.TYPE_LAST_COLOR_INT) {
// windowBackground is a color
int color = a.data;
} else {
// windowBackground is not a color, probably a drawable
Drawable d = activity.getResources().getDrawable(a.resourceId);
}

您可以使用以下方式获取主题资源:
TypedArray a = getTheme().obtainStyledAttributes(R.style.ThemeName, new int[] {R.attr.attribute_name});
int attributeResourceId = a.getResourceId(0, 0);

对于你的qoustion最简单的方法是:
TypedValue typedValue = new TypedValue();
if (this.parentActivity.getTheme().resolveAttribute(android.R.attr.windowBackground, typedValue, true))
{
// how to get color?
int colorWindowBackground = typedValue.data;// **just add this line to your code!!**
}
