问题描述
我想在 Android Studio 中将一些 vectorDrawables 设置为 ImageView.
I want to set some vectorDrawables to a ImageView in Android Studio.
我可以轻松设置 png 和 jpg drawable,但是当我想设置 VectorDrawable 时,它不适用于 imageview.
I can set png and jpg drawable easily but when i want to set VectorDrawable, it does not work on imageview.
img.setImageResource(R.drawable.ic_home);
ic_home 是 VectorDrawable 且此代码不起作用.
ic_home is VectorDrawable and this code doesn't work.
推荐答案
如果您想使用矢量可绘制对象(小于或大于 API 21),只需执行以下操作:
If you want to use vector drawables (less OR greater than API 21) just do the following:
以编程方式设置图像(例如在您的活动中):
Set the image programmatically (e.g. in your activity):
imageView.setImageResource(R.drawable.ic_left_arrow_blue);
或通过 XML:
app:srcCompat="@drawable/your_vector_name"
在您应用的 build.gradle
中,您需要包含:
In your app's build.gradle
you need to include:
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}
对于低于 API 21 的矢量支持,将以下内容添加到 onCreate
:
And for vector support for less then API 21, add the following to onCreate
:
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
