問題タブ [android-parser]

私はこのチュートリアルを読んでいて、非常に低い API を使用しているという問題に遭遇しました。NetworkOnMainThreadException を受け取りました。AsyncTaskを使用する必要があるというスタックオーバーフローでこの回答を見つけました。

空のプロジェクトで AsyncTask を使用して、別のチュートリアルを使用してみましたが、うまくいきました。

私の問題は、より高い API で使用できるように、このプロジェクトを変更する必要があることです。つまり、AndroidSaxFeedParser はサブクラスであり、AsyncTask はスーパー クラスであり、エラー行は AndroidSaxFeedParser にあり、BaseFeedParser を拡張し、BaseFeedParser はインターフェースである FeedParser を拡張します (ところで、拡張ではなくインターフェースを実装する必要があると常に考えていましたか?)。

より正確には、エラーは次の行にあります ( ---> で示されます): AndroidSaxFeedParser.java :

MessageList.java :

BaseFeedParser.java :

では、どこでどのように AsyncTask を使用すればよいのでしょうか。(私は AndroidSaxParser のみを使用しているため、チュートリアルの他のパーサーは無視できます)。

AndroidSaxFeedParser.java

BaseFeedParser.java

FeedParser.java

FeedParserFactory.java

メッセージ.java

MessageList.java

ParserType.java

RssHandler.java

オブジェクトが空白になりBufferedReaderました。コードをデバッグすると、実際にはHttpEntityオブジェクトも空のように見えることがわかりました。

コードの私の部分は次のとおりです。

//HTTPリクエストの作成

PC ブラウザーで自分の URL にアクセスすると、JSON 応答が返され、[http://jsonlint.com/][1] でも返されます。

正確な問題は何ですか、私には理解できません

解析中にエラーを表示します。ユーザーが取得した整数値を渡したいだけです。しかし、解析中にエラーが表示されます。さらに、ユーザーから整数値を受け入れる方法と、それを整数形式で渡す方法の問題を修正します。コーディング：

edittext の xml 部分

スタックトレース：

java.lang.reflect.Method.invoke(Method.java:507)

私の Android アプリケーションでは、PHP URL から JSON 応答文字列を取得します。応答から、 のホテル名をいくつか取得します。代わりに文字apostropheを取得します。Androidで特殊文字を使用してホテルを解析するにはどうすればよいですか?&#039apostropheI can see the apostrophe in the browser but could not see in android logcat.

試してみましたが、ホテル名をjresponse = URLEncoder.encode(jresponse,"UTF-8");取得できませんでした。apostrophe

これは、応答のホテル名の 1 つです。

購入ステータス API ( https://www.googleapis.com/androidpublisher/v1.1/applications/packageName/subscriptions/subscriptionId/purchases/token )を使用してサブスクリプションの有効期限を取得しようとしていますが、応答を下回っています。私の目的を達成する正しい方法ですか？

誰もそれを行う方法を知っていますか?

前もって感謝します。

JSON解析データをアンドロイドにしようとしています。

理解できない私のエラーは何ですか。

私はJavaとAndroidの初心者でもあります。

このコードは難しくありません。退屈することはありません。

私のエラーとコードは次のとおりです。

私のAndroidアプリケーションでは、非常に奇妙なエラーに直面しており、そのルートに入ることができません. ネットワーク呼び出しを行い、JSON 応答を解析しています。しかし、アプリケーションがクラッシュし、次のエラーが表示されます。

ランダムに発生し、エラーを再現できません。以前にこれに直面したことがある人が、何がこのクラッシュを引き起こす可能性があるかを教えてくれれば、非常に便利です.

進行状況バーで asynctask を使用する JSON パーサー。これを行う正しい方法は何ですか？

tutsから読み取ったものを適用して適応させましたが、downloadTaskからデータを返すときにnullを返します

これが私のdownloadTaskタスクです：

これは基本的に populateCampaigns メソッドです。

最後に、パーサー メソッドを次に示します。
