If the byte array of the vector drawable you have has a binary XML form, then you should be able to create it by passing the array to the following method I took from my previous answer :
(如果您可以绘制的向量vector的字节数组具有二进制XML形式，那么您应该可以通过将数组传递给我从上一个答案中获取的以下方法来创建它：)
/**
* Create a vector drawable from a binary XML byte array.
* @param context Any context.
* @param binXml Byte array containing the binary XML.
* @return The vector drawable or null it couldn't be created.
*/
public static Drawable getVectorDrawable(@NonNull Context context, @NonNull byte[] binXml) {
try {
// Get the binary XML parser (XmlBlock.Parser) and use it to create the drawable
// This is the equivalent of what AssetManager#getXml() does
@SuppressLint("PrivateApi")
Class<?> xmlBlock = Class.forName("android.content.res.XmlBlock");
Constructor xmlBlockConstr = xmlBlock.getConstructor(byte[].class);
Method xmlParserNew = xmlBlock.getDeclaredMethod("newParser");
xmlBlockConstr.setAccessible(true);
xmlParserNew.setAccessible(true);
XmlPullParser parser = (XmlPullParser) xmlParserNew.invoke(
xmlBlockConstr.newInstance((Object) binXml));
if (Build.VERSION.SDK_INT >= 24) {
return Drawable.createFromXml(context.getResources(), parser);
} else {
// Before API 24, vector drawables aren't rendered correctly without compat lib
final AttributeSet attrs = Xml.asAttributeSet(parser);
int type = parser.next();
while (type != XmlPullParser.START_TAG) {
type = parser.next();
}
return VectorDrawableCompat.createFromXmlInner(context.getResources(), parser, attrs, null);
}
} catch (Exception e) {
Log.e(TAG, "Vector creation failed", e);
}
return null;
}
I haven't tested it but I don't see a reason why it shouldn't work if your byte array really is the binary XML of a vector drawable, which is what the XmlPullParser and VectorDrawable expects to parse.
(我还没有测试过，但是我不明白为什么如果您的字节数组确实是矢量可绘制对象的二进制XML，它不起作用的原因，这就是XmlPullParser和VectorDrawable希望解析的。)
EDIT: I tried using XmlPullParser to create the drawable like this:
(编辑：我尝试使用XmlPullParser创建像这样的可绘制对象：)
val xml = """
|<vector xmlns:android="http://schemas.android.com/apk/res/android"
| android:width="24dp"
| android:height="24dp"
| android:viewportWidth="24.0"
| android:viewportHeight="24.0">
| <path
| android:pathData="M9.5,3A6.5,6.5 0,0 0,3 9.5A6.5,6.5 0,0 0,9.5 16A6.5,6.5 0,0 0,13.33 14.744L18.586,20L20,18.586L14.742,13.328A6.5,6.5 0,0 0,16 9.5A6.5,6.5 0,0 0,9.5 3zM9.5,5A4.5,4.5 0,0 1,14 9.5A4.5,4.5 0,0 1,9.5 14A4.5,4.5 0,0 1,5 9.5A4.5,4.5 0,0 1,9.5 5z"
| android:fillColor="#000000"/>
|</vector>
""".trimMargin()
val parser = XmlPullParserFactory.newInstance().newPullParser()
parser.setInput(xml.reader())
val drawable = Drawable.createFromXml(resources, parser, theme)
iconView.setImageDrawable(drawable)
However this fails with an exception: java.lang.ClassCastException: android.util.XmlPullAttributes cannot be cast to android.content.res.XmlBlock$Parser.
(但是，此操作失败，并出现以下异常：java.lang.ClassCastException：android.util.XmlPullAttributes无法转换为android.content.res.XmlBlock $ Parser。)
So this is not possible after all to answer your comment. (因此，这根本不可能回答您的评论。)
