リストビューの項目を検索して欲しい項目をクリックすると、リストビューの最初の位置が常に開かれます

Question

MainActivity.class 問題は、リストビューから任意の項目を検索してそれをクリックするときです私が検索したときに、プログラムに追加されていない最初のポジション項目を開きます。あなたはそれが配列アダプタから一致する項目をフィルタ表示、検索にテキストを入力し、あなたの場合は

Answer 1

。

したがって、配列のすべての項目は、配列アダプタを設定するときに同じではない位置を再定義します。ここで

、あなたはコードの行の下に見つけることができるためsCheeseStrings

から選択した結果の位置を見つける必要があります。疑問があればお尋ねください。

 String itemValue = (String) mListView.getItemAtPosition(position); 

     int itemPosition = 0; 
      for (int i = 0; i < mStrings.length; i++) { 
       if (itemValue.equalsIgnoreCase(mStrings[i])) { 
        itemPosition = i; 
       } 
      } 

      if (itemPosition == 0) { 
       String content = "android.intent.action.FIRST_PROG"; 
       Intent i = new Intent(content); 
       startActivity(i); 
      } 
      if (itemPosition == 1) { 
       Intent i = new Intent("android.intent.action.SECOND_PROG"); 
       startActivity(i); 
      } 
      if (itemPosition == 2) { 
       Intent i = new Intent("android.intent.action.THIRD_PROG"); 
       startActivity(i); 
      }
