我正在尝试从我的Android项目中的jar文件中读取一个drawable xml文件。
private Drawable readDrawableFromJar(String p_strFilePath) {
InputStream stream = getClass().getClassLoader().getResourceAsStream(p_strFilePath);
XmlPullParser parser = null;
try {
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
parser = factory.newPullParser();
parser.setInput(stream, "UTF-8");
} catch (XmlPullParserException e) {
Log.e(LOG_TAG, "there is something for " + p_strFilePath + " " + e);
}
Drawable drawable = null;
try {
if (parser != null) {
drawable = VectorDrawableCompat.createFromXml(getContext().getResources(), parser);
return drawable ;
} else {
Log.e(LOG_TAG, "parser is null for " + p_strFilePath);
}
} catch (XmlPullParserException e) {
Log.e(LOG_TAG, "there is something for " + p_strFilePath + " " + e);
} catch (IOException e) {
Log.e(LOG_TAG, "there is something for " + p_strFilePath + " " + e);
}
return null;
}
这个方法可以找到文件并读取文本内容。但是,当它设置输入时,会抛出以下异常:
org.xmlpull.v1.XmlPullParserException: unsupported feature: http://xmlpull.org/v1/doc/features.html#validation (position:START_DOCUMENT null@1:1)
这真的很奇怪,因为XML文件中不包含任何这样的文本:http://xmlpull.org/v1/doc/features.html#validation
这是位于JAR文件中的XML文件。
