问题描述
您可能会认为这个问题是 this 一个.但是从那以后，Android Studio进行了更新，给出的解决方案不再起作用.
You might be thinking this question is a duplicate of this one. But since then, Android Studio has been updated and the solution given there is not working anymore.
为什么在创建图像资产时被迫具有背景?这背后的原因是什么?我们应该如何在没有任何背景的情况下更改launcher_icon?我看不到任何禁用图像资产背景的选项.
Why are we forced to have a background when creating an Image Asset? What's the reason behind this? How we are supposed to change the launcher_icon without having any background? I don't see any option to disable the background in Image Asset.
或者，我使用一个空的背景，但是在全出血层中不起作用:
Alternatively, I use an empty background but this doesn't work in Full Bleed Layers:
<?xml version="1.0" encoding="utf-8"?>
<vector
android:height="108dp"
android:width="108dp"
android:viewportHeight="108"
android:viewportWidth="108"
xmlns:android="http://schemas.android.com/apk/res/android">
</vector>
或者，只需删除背景，但这会在您的launcher_icon中添加白色背景:
Or, just remove the background, but this will add a white background in your launcher_icon:
<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Remove the background here and leave the foreground -->
<foreground android:drawable="@drawable/ic_launcher_foreground"/>
</adaptive-icon>
或者，将icon type更改为Legacy Only并将shape设置为none:
Or, change icon type into Legacy Only and set shape to none:
仍然，启动器图标在安装后仍为白色背景.
Still, there's a white background in the launcher icon when installed.
那么，如何使用图像资产"为我的启动器图标获得透明背景，或者没有透明背景?
So how can I get a transparent background or none for that matter, for my Launcher icon using Image Asset?
推荐答案
这不是您使用Android Studio创建的图标的问题，而是与您要在其上测试应用程序的特定设备有关的问题.实际上，在图像资产"中，如果将形状"指定为无"，则会得到透明背景.
It is not a problem of the icon you created with Android Studio, but it's a problem related to your specific device you're testing the application on.In fact, in the Image Asset if you specify the Shape to None, you get a trasparent background.
要解决您的问题，请尝试使用其他首页主题，例如 Nova启动器；您可以在设置"主页"中更改主页主题.
To address your problem, please try to use a different Home theme, like the Nova Launcher; you can change the home theme in Settings - Home.
