推荐答案
使用 myBitmap是要从中提取颜色的图像.
同样对于API 21及更高版本，如果您打算为状态栏和导航栏着色，则需要添加以下标志:
Where myBitmap is the Image from which you want to extract the color.
Also for API 21 and above, you'll need to add the following flags if you're planning to color the status bar and navigation bar:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
}
