如何以编程方式将VectorDrawable设置为ImageView的图像 [英] How to set VectorDrawable as an image for ImageView programmatically
问题描述
我想在Android Studio中将 vectorDrawables 设置为 ImageView 。
I want to set some vectorDrawables to a ImageView in Android Studio.
我可以设置png和jpg很容易绘制,但是当我想设置VectorDrawable时,它在imageview上不起作用。
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,此代码不起作用。
ic_home is VectorDrawable and this code doesn't work.
推荐答案
如果你想使用矢量drawables(比API 21更小或更大),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XML:
app:srcCompat="@drawable/your_vector_name"
在你的应用中 build.gradle
你需要包括:
In your app's build.gradle
you need to include:
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}
对于少于API 21的向量支持,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);
