1回の活動で500の質問クイズをアンドロイドで作成するには？

Question

私はAndroidのアプリケーションを作成しています。ここでは、RadioButtonsを使用して複数のタイプの質問をしています。私はこれらの質問に対して複数の活動をしたくありません。誰かが、少なくとも2つの質問の短い例でそれを行う方法を教えてもらえますか？

Answer 1

複数のフラグメントを使用することも、アクティビティ自体を複数回呼び出すこともできます... 私はあなたのようなアプリを使い、私は最初の方法を選びました！

これは私が書いたプロジェクトの断片であり、それを操作するアクティビティは、必要に応じて変更する必要があります。

活動

public class CollectActivity extends FragmentActivity { 

    MyPageAdapter pageAdapter; 
    NonSwipeableViewPager pager; 
    SpringIndicator springIndicator; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_collect); 
     List<Fragment> fragments = getFragments(); 
     pager = (NonSwipeableViewPager) findViewById(R.id.view_pager); 

     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 

     PagerModelManager manager = new PagerModelManager(); 
     manager.addCommonFragment(fragments, getTitles()); 


     ModelPagerAdapter adapter = new ModelPagerAdapter(getSupportFragmentManager(), manager); 
     pager.setAdapter(adapter); 
     springIndicator = (SpringIndicator) findViewById(R.id.indicator); 
     springIndicator.setViewPager(pager); 
     springIndicator.setOnTabClickListener(new TabClickListener() { 
      @Override 
      public boolean onTabClick(int position) { 
       return false; 
      } 
     }); 


    } 

    private List<Fragment> getFragments() { 
     List<Fragment> fList = new ArrayList<Fragment>(); 
     fList.add(CollectFragment.newInstance("Fragment 1")); 
     fList.add(CollectFragment.newInstance("Fragment 2")); 
     fList.add(CollectFragment.newInstance("Fragment 3")); 
     //add your fragments with a loop 

     return fList; 
    } 

    private List<String> getTitles() { 
     return Lists.newArrayList("1", "2", "3"); 
    } 


    public void swipeFragment() { 

     pager.setCurrentItem(pager.getCurrentItem() + 1); 

    } 

    public int getFragment() { 
     return pager.getCurrentItem(); 

    } 


}
