Log.i( "RSSHandler"、 "localName =" + localName + "、qName =" + qName);を使用した場合のlogcatは次のとおりです。

私はこのようにコードを変更しようとしました:
else if(qName.trim().equalsIgnoreCase("media:content") || value.equalsIgnoreCase("content")){
if (attributes != null) {
mMediaContent = new MediaContent();
mHrefAttribute_media = attributes.getValue("url");
Log.i("media url", mHrefAttribute_media);
}
isMedia = true;
Log.i("media group", "media content");
}
しかし、これは機能していません。
この応答からmedai:groupを読み取ることができません。私はこれを試しましたが、結果を得ることができません。誰かがこれをするのを手伝ってくれませんか。ありがとうございました。
