Why does my icon look different to the other icons on the screen? 为什么我的图标看起来与屏幕上的其他图标不同？ In Android Studio, I set trim to zero and yet it still shows up like this on my phone. 在Android Studio中，我将trim设置为零，但它仍然像这样在手机上显示。 I have Nova Launcher installed which makes all my apps have rounded icons, but look at the Google Maps, and Instagram, how do I get my icon to fill the circle? 我安装了Nova Launcher，这使我所有的应用程序都具有圆形的图标，但是看看Google Maps和Instagram，如何使我的图标填充整个圆圈？
