조각의 레이아웃에 목록보기 어댑터 추가

Question

내 Listview의 내용을 동적으로 생성하고 싶지만이 경우에는 어떻게 해야할지 모릅니다. 주요 활동이 아니라 조각에 있기 때문입니다. 레이아웃 파일 아래

public class DummySectionFragment extends Fragment { 
/** 
* The fragment argument representing the section number for this fragment. 
*/ 
public static final String ARG_SECTION_NUMBER = "section_number"; 

public DummySectionFragment() { 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    View rootView = inflater.inflate(R.layout.fragment_contacts_dummy, 
      container, false); 
    if (getArguments().getInt(ARG_SECTION_NUMBER) == 2) { 

     rootView = inflater.inflate(R.layout.contact_section, container, 
       false); 
     ListView listView1 = (ListView) rootView 
       .findViewById(R.id.listview); 

    } else { 
     TextView dummyTextView = (TextView) rootView 
       .findViewById(R.id.section_label); 
     dummyTextView.setText(Integer.toString(getArguments().getInt(
       ARG_SECTION_NUMBER))); 
     String[] values = new String[] { "Android", "iPhone", 
       "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", 
       "Windows7", "Max OS X", "Linux", "OS/2", "Ubuntu", 
       "Windows7", "Max OS X", "Linux", "OS/2", "Ubuntu", 
       "Windows7", "Max OS X", "Linux", "OS/2", "Android", 
       "iPhone", "WindowsMobile" }; 

     final ArrayList<String> list = new ArrayList<String>(); 
     for (int i = 0; i < values.length; ++i) { 
      list.add(values[i]); 
     } 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>  (this,R.id.listview); 
    } 

    return rootView; 
} 
} 

은 다음과 같습니다 :

public class Contacts extends FragmentActivity implements ActionBar.TabListener { 

SectionsPagerAdapter mSectionsPagerAdapter; 

/** 
* The {@link ViewPager} that will host the section contents. 
*/ 
ViewPager mViewPager; 
ListView myListView; // Listview here 
ListView listview; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_contacts); 

    // Set up the action bar. 
    final ActionBar actionBar = getActionBar(); 
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

    // Create the adapter that will return a fragment for each of the three 
    // primary sections of the app. 
    mSectionsPagerAdapter = new SectionsPagerAdapter(
      getSupportFragmentManager()); 

    // Set up the ViewPager with the sections adapter. 
    mViewPager = (ViewPager) findViewById(R.id.pager); 
    mViewPager.setAdapter(mSectionsPagerAdapter); 
    getActionBar().setDisplayShowTitleEnabled(false); 
    getActionBar().setDisplayUseLogoEnabled(false); 
    getActionBar().setDisplayShowHomeEnabled(false); 
    // When swiping between different sections, select the corresponding 
    // tab. We can also use ActionBar.Tab#select() to do this if we have 
    // a reference to the Tab. 
    mViewPager 
      .setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { 
       @Override 
       public void onPageSelected(int position) { 
        actionBar.setSelectedNavigationItem(position); 
       } 
      }); 

    // For each of the sections in the app, add a tab to the action bar. 
    for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) { 
     // Create a tab with text corresponding to the page title defined by 
     // the adapter. Also specify this Activity object, which implements 
     // the TabListener interface, as the callback (listener) for when 
     // this tab is selected. 
     actionBar.addTab(actionBar.newTab() 
       .setText(mSectionsPagerAdapter.getPageTitle(i)) 
       .setTabListener(this)); 
    } 

} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.contacts, menu); 
    return true; 
} 

@Override 
public void onTabSelected(ActionBar.Tab tab, 
     FragmentTransaction fragmentTransaction) { 
    // When the given tab is selected, switch to the corresponding page in 
    // the ViewPager. 
    mViewPager.setCurrentItem(tab.getPosition()); 
} 

@Override 
public void onTabUnselected(ActionBar.Tab tab, 
     FragmentTransaction fragmentTransaction) { 
} 

@Override 
public void onTabReselected(ActionBar.Tab tab, 
     FragmentTransaction fragmentTransaction) { 
} 

/** 
* A {@link FragmentPagerAdapter} that returns a fragment corresponding to 
* one of the sections/tabs/pages. 
*/ 
public class SectionsPagerAdapter extends FragmentPagerAdapter { 

    public SectionsPagerAdapter(FragmentManager fm) { 
     super(fm); 
    } 

    @Override 
    public Fragment getItem(int position) { 
     // getItem is called to instantiate the fragment for the given page. 
     // Return a DummySectionFragment (defined as a static inner class 
     // below) with the page number as its lone argument. 
     Fragment fragment = new DummySectionFragment(); 
     Bundle args = new Bundle(); 
     args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    @Override 
    public int getCount() { 
     // Show 3 total pages. 
     return 3; 
    } 

    @Override 
    public CharSequence getPageTitle(int position) { 
     Locale l = Locale.getDefault(); 
     switch (position) { 
     case 0: 

      return getString(R.string.contacts).toUpperCase(l); 
     case 1: 
      return getString(R.string.title_section2).toUpperCase(l); 
     case 2: 
      return getString(R.string.title_section3).toUpperCase(l); 
     } 
     return null; 
    } 
} 

private class StableArrayAdapter extends ArrayAdapter<String> { 

    HashMap<String, Integer> mIdMap = new HashMap<String, Integer>(); 

    public StableArrayAdapter(Context context, int textViewResourceId, 
      List<String> objects) { 
     super(context, textViewResourceId, objects); 
     for (int i = 0; i < objects.size(); ++i) { 
      mIdMap.put(objects.get(i), i); 
     } 
    } 

    @Override 
    public long getItemId(int position) { 
     String item = getItem(position); 
     return mIdMap.get(item); 
    } 

    @Override 
    public boolean hasStableIds() { 
     return true; 
    } 

} 

} 

그리고 조각 : 여기 는 코드입니다

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/pager" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".Contacts" /> 

두 번째 레이아웃 :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".Contacts$DummySectionFragment" > 

<TextView 
    android:id="@+id/section_label" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" /> 

<ListView 

    android:id="@+id/listview" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" />

그다지 어렵지 않습니다. Listactivity 또는 활동, 조각 또는 listfragment 모두 괜찮습니다. 어쩌면리스트 *는 코드가 적을 것입니다.

액티비티 또는 조각에서 어댑터를 설정합니다. 예를 들어 ArrayAdapter를 사용합니다. 목록에 제거 옵션이있는 경우 요소를 지원하려면 LinkedList을 사용해야하거나 추가 옵션에 ArrayList을 사용해야합니다. 어댑터를 목록보기로 설정하십시오.

새 요소가 오거나 삭제 될 때마다 목록 (LinkedList 또는 Arraylist) add 또는 remove을 호출 한 다음 어댑터의 notifyDataSetChanged 메서드를 호출하십시오.

내가 S, A 시도 하바하시기 바랍니다 '고 new ArrayAdapter<String>(..., ..., ..., List<?>...)

, 다음과 같이의 생성자'당신이 ArrayAdapter와에 목록 (LinkedList의 또는 ArrayList를)를 추가하는 것을 잊지 supose!
