小图标是强制性我尝试删除该图标,但我的应用程序崩溃** ** 参考线
mBuilder.setLargeIcon(BitmapFactory.decodeResource(getBitmapFromURL("YOUR URL"));
按照通知小图标的新的行为是强制性的。如果你想在你的通知中显示来自网络的图像,你可以使用BIGPicture来设置你的通知,在那里你可以在你的通知的下方显示图像。像flipkart在他的通知中显示 –
查看setSmallIcon的源代码,我只能看到setSmallIcon(int图标)和setSmallIcon(int图标,int级别) - 所以你必须指定一个资源。你可能可以在运行时动态地做到这一点,但我认为这将是hacky。 – Ewald
感谢您的回复。如果我删除函数setSmallIcon()我的应用程序崩溃。但是R.drawable.ic_launcher是R.java文件的一部分。我不需要访问R.java可绘制的整数值。我需要为setSmallIcon(或)设置图像路径而不使用setSmallIcon函数如何设置通知图像 –
