Android的ListFragment失败setContentView

Question

我一直试图让一个listview在一个片段内工作一整天。我不知道为什么，但由于某种原因，我试图做到这一点，它只是从来不想膨胀视图。我使用actionbarsherlock如果这有所作为，但我不这么认为。继承人在那里我的布局失败等级：

public class GraffSearch extends FragmentActivity implements ActionBar.TabListener{ 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);  
    setContentView(R.layout.searchlayout);//<-------------fails here 

    final ActionBar ab = getSupportActionBar(); 

    for (int i = 1; i < 4; i++) { 
     ab.addTab(ab.newTab().setText("Tab " + i).setTabListener(this)); 
    } 


    ab.show(); 
    if (ab.getNavigationMode() != ActionBar.NAVIGATION_MODE_TABS) { 
     ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 
    } 



} 

@Override 
public void onTabReselected(Tab tab, FragmentTransaction ft) { 
    // TODO Auto-generated method stub 

} 

@Override 
public void onTabSelected(Tab tab, FragmentTransaction ft) { 
    //Toast.makeText(this, "tabs work "+tab.getPosition()+" user id is "+avrid, Toast.LENGTH_LONG).show(); 
    SearchListFrag fragment = (SearchListFrag) getSupportFragmentManager().findFragmentById(R.id.searchfrag); 
    //fragment.updateUrl(tab.getPosition(), avrid); 

} 

@Override 
public void onTabUnselected(Tab tab, FragmentTransaction ft) { 
    // TODO Auto-generated method stub 

} 

}

和继承人的布局是我叫我的片段。

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
> 


<ListFragment 
    android:id="@+id/searchfrag" 
    android:layout_width="0dip" 
    android:layout_height="match_parent" 
    android:name="graffit.main.SearchListFrag" 
    android:layout_weight="1"></ListFragment> 



</LinearLayout> 

编辑：我searchlistfrag类

public class SearchListFrag extends Fragment{ 

ListView markList; 

public SearchListFrag(){}; 

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
    markList = (ListView) inflater 
       .inflate(R.id.searchlist, container, false);//<----------Fails Here 
    markList.setAdapter(new OrderAdapter(
      MixView.mixContext.getBaseContext(), 
      R.layout.searchinnerlistlayout, 
      MixView.dataView.dataHandler.markerList)); 


    // return inflater.inflate(R.layout.searchlistlayout, container, false); 
    return markList;    

    } 


    @Override 
    public void onPause() { 

     super.onPause(); 
    } 

    @Override 
    public void onResume() { 
     super.onResume(); 

    } 

    public void updateUrl(int tab, String avrid) { 

    } 

    private class OrderAdapter extends ArrayAdapter<Marker> { 

     private ArrayList<Marker> marks; 

     public OrderAdapter(Context context, int textViewResourceId, ArrayList<Marker> items) { 
       super(context, textViewResourceId, items); 
       this.marks = items; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
       View v = convertView; 
       if (v == null) { 
        LayoutInflater vi = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        v = vi.inflate(R.layout.searchinnerlistlayout, null); 
       } 
       // Order o = items.get(position); 
       if (marks.get(position) != null) { 
         TextView title = (TextView) v.findViewById(R.id.title); 
         //TextView description = (TextView) v.findViewById(R.id.description); 
         if (title != null) { 
           title.setText("Title: "+marks.get(position).getTitle());       } 
         //if(description != null){ 
         // description.setText("Description: "+ +marks.get(position).get); 
         // } 
         ImageView icon = (ImageView) v.findViewById(R.id.markimage); 
         icon.setImageBitmap(marks.get(position).getBitmap()); 
       } 

       return v; 
     } 
} 
} 

编辑：我searchlistlayout布局

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    > 
<ListView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:name="@+id/searchlist"></ListView> //<----this is the id i use that fails 

</LinearLayout> 

香港专业教育学院尝试了几种不同的设置去使用常规的片段，并用listfragment来回相同的结果。这里是logcat。

Answer 1

在布局片段导入是错误的。碎片被添加到<fragment>标签的布局中。除Views之外，您不会在完全限定的类名称后面命名该标签。发生此错误的原因是Android尝试用类型为'ListFragment'的View膨胀，该类型不存在。

尝试：

<fragment 
    android:id="@+id/searchfrag" 
    android:layout_width="0dip" 
    android:layout_height="match_parent" 
    android:name="graffit.main.SearchListFrag" 
    android:layout_weight="1"></fragment> 

的<fragment>必须是小写，<Fragment>不会太工作。

你混合了一些东西了。

1）片段的onCreate方法具有以膨胀片段的整个布局。在对Fragment布局进行充气后，您可以获得ListView。

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View contentView = inflater.inflate(R.id.searchlist, container, false);  
    markList = (ListView) contentView.findViewById(R.id.searchlist); 
    markList.setAdapter(new OrderAdapter(MixView.mixContext.getBaseContext(), R.layout.searchinnerlistlayout, MixView.dataView.dataHandler.markerList)); 

    return contentView; 
} 

2）您没有定义ListView的ID，您定义了它的名称。更改布局：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    > 
<ListView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/searchlist"></ListView> 
</LinearLayout>
