2つのリストビューと2つのアダプタを持つレイアウトがあります。最初のリストは、Webサービスコールの最初の人物を表示したいだけです。 2番目のリストビュー私は彼らがその人に報告するときに私が得たリストを表示したい。ユーザーが2番目のリストをクリックすると、それらからのパラメータを使ってWeb呼び出しを行います。リストビューを更新する新しいアクティビティには行かずにWebサービスコールから2リストビューを表示
新しいリストを取得し、そのリストビューをリフレッシュして別のアクティビティに移動しないように、もう一度paramを呼び出して2番目のリストビューを更新するにはどうすればよいですか？私はウェブサービスを正しく作ることができますが、私は新しい活動に行きます。 2番目のlistviewの新しいデータと、ユーザーがトップリストビューに表示するためにクリックした人物のリストビューを更新したいだけです。私はbottomListViewはちょうど別のアクティビティに行くことなく、新しいデータを表示するリストビューを更新するために取得する方法を確認していないよう

他のアダプタは同じです。
私はTopListViewAdapterのためにMainAcitivy.classが必要ではありませんが、私はTopListViewAdapterを求めていますが、解析された応答の最初の人物を取得する方法もわかりません。
