アンドロイドのsaxパーサーでタグを解析した後、エミュレータでnull値を表示しますか？

Saxパーサーを使用してwebservicesのアンドロイドに小さなアプリケーションを作成しています。私のリンクはです（http://www.anddev.org/images/tut/basic/parsingxml/example.xml)Iの値を表示できます** < ** innertag>、******）ここでtheTextViewで
の値を表示することExtractedString1のISN「を設定します。したがって、コード文字でブロック（）関数）あなたはのstartElement（でコメントアウトthis.in_mytag = trueを持っている私のsorcsコードアンドロイドのsaxパーサーでタグを解析した後、エミュレータでnull値を表示しますか？
