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);
