する必要がある

  • ユーザーがAndroidをクリックしたときに大文字と小文字を切り替えて別のアクティビティにデータを表示する
  • 次に、データ android Lerner または android developers を表示します。次に、android 学習者をクリックします。
  • 次に、android lerner1 または android learner2 を表示します
  • Android 開発者を選択すると、Android lerner1 または Android Learner2 が表示されます。

ここでは、android でのみ機能し、iphone やウィンドウでは機能しません。

これはどう

使用法: TutorialUtils.getMenu();、TutorialUtils.getMenu(new int[] { 0 })、TutorialUtils.getMenu(new int[] { 2, 1 })またはあなたの場合はいくつかの変更を加えTutorialUtils.getMenu(getIntent().getExtras().getIntArray("positionsHistory"))た .

TutorialUtilsクラス、例外を自分で処理します。

import java.util.ArrayList;
import java.util.List;

public class TutorialUtils {
private static CompositeTutorialNode nodes = new CompositeTutorialNode(
