我正在尝试将此XML用作应用程序内的图标.
I am trying to use this XML as an icon inside my app.
但是,由于某些原因,当我这样做
However, for some reason, when I do
<ImageView src="@drawable/icon"/>
使用API 23运行时,我的应用立即崩溃.
Running on API 23, My app would immediately crashes on me.
但是,在API级别19上,同一应用程序可以正常运行.
However, on API level 19, the same app runs without any issues.
如果我删除该< gradient>
标记,则API 23也可以正常运行.
If I remove that <gradient>
tag, the API 23 runs fine as well.
我应该怎么做才能使API 23中的应用程序没有任何问题?
What should I do so that the app in API 23 without any issue?
推荐答案
此处的主要问题是您尝试使用为API 24定义的渐变和属性,例如 android:fillType
和带有API 19的设备中的android:startY
.
The main problem here is that you are trying to use gradient and properties defined for API 24 such android:fillType
and android:startY
in a device with API 19.
解决方案是:
创建2个drawables文件夹
Create 2 drawables folders
-
可绘制
-
drawable-v24
在
drawable
文件夹中将其作为your_logo.xml
放置(我使用了从渐变中提取的#FFFA8561
)
Put this as
your_logo.xml
in thedrawable
folder (I've used#FFFA8561
took from the gradient)

创建此
gradient_logo.xml
文件并将其放在drawable-v24
文件夹中(不必担心Android Studio抱怨此文件,即使编译该文件也可以正常工作如果标记为红色)
Create this
gradient_logo.xml
file and put it on thedrawable-v24
folder (don't worry about Android Studio complaining about this file, it will compile fine even if marked with red)
<?xml version="1.0" encoding="utf-8"?>

使用
AppCompatImageView
添加图像
<android.support.v7.widget.AppCompatImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/your_logo"/>
结论:这样,您的项目将可以正常编译,但是您会注意到最终将得到2个略有不同的徽标,一个徽标用于API> = 24,另一个徽标用于API< =23.
Conclusions: In this way your project will compile fine, but you will notice that you will end up with 2 slightly different logos, one for API >= 24 and another one for API <=23.
我不知道这是否可以接受,但是如果您关心徽标在每个平台上都不完全相同,则可用的解决方案是那些解决方案:
I don't know if this is acceptable to you, but if you care about your logo not to be the exactly the same on every platform, the solutions available are those ones:
- 请勿在徽标中使用矢量.使用分发在
mipmap
文件夹中的经典PNG集. - 请勿在徽标中使用渐变色,而应使用与API> = 19兼容的平面版本
- Don't use vectors for your logo. Use the classic PNG set distributed in the
mipmap
folders. - Don't use a gradient in your logo and go for the flat version which is compatible with API >=19
