VectorDrawable向后兼容性和安装非官方支持库 [英] VectorDrawable Backwards Compatibility And Installing Unofficial Support Libraries
问题描述
与我同在,我是新来的!
我想在我的android应用程序中使用vectors,并且我希望我的应用程序向后兼容.我发现此支持库看起来很酷!*
因此,我对如何安装"它感到困惑.它为您提供了下载.pom,.aar,javadoc.jar和sources.jar文件的链接.我应该下载哪一个文件,以及将文件放在哪里(哪个文件夹)?
(我正在使用Android Studio!)
*(有人知道另一个VectorDrawable支持库吗?我想听听大家的经验!)
Bear with me, I'm new!
I want to use vectors in my android app, and I want my app to be backwards compatible. I found this support library that looks pretty cool!*
So I'm confused about how I would I 'install' it. It gives you a link to download the .pom, .aar, javadoc.jar, and the sources.jar file. Which one should I download, and where (what folder) should I put the file?
(I'm using Android Studio!)
*(Anybody know a different VectorDrawable support library? I'd be interested in hearing everybody's experience!)
推荐答案
以下是对我有用的选项 使用此库- https://github.com/wnafee/vector-compat (api 14 +)
Here is a option that worked for me Use this library - https://github.com/wnafee/vector-compat (api 14+)
android {
// use version 22 or higher
buildToolsVersion "22.0.1"
...
}
dependencies {
compile 'com.wnafee:vector-compat:1.0.5'
...
}
并创建一个使用vector compat类的自定义ImageView类-
And create a custom ImageView class that uses vector compat class -
public class SvgImageView extends ImageView {
private Drawable icon;
public SvgImageView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray ta = context.obtainStyledAttributes(attrs,
R.styleable.button_left, 0, 0);
try {
int resId = ta.getResourceId(R.styleable.button_left_b_icon, -1);
if (resId != -1) {
icon = ResourcesCompat.getDrawable(this.getContext(), resId);
}
} finally {
ta.recycle();
}
if (icon != null) {
setImage(icon);
}
}
public void setImage(Drawable icon) {
SvgImageView.this.setImageDrawable(icon);
}
}
