Android - ListFragment在setContentView上失败

标签: android listview android-layout android-fragments

我一直试图让listview整天在片段中工作。我不知道为什么但由于某种原因我试图这样做,它只是永远不想膨胀视图。我使用actionbarsherlock,如果这有所作为,但我不这么认为。继承我布局失败的班级:

 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

}

}

并且继承布局是我称之为片段。

<?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:我的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:我的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>

我尝试了一些不同的设置来回使用常规片段和具有相同结果的listfragment。这是logcat。

答案 0 :(得分:4)

布局中的片段导入错误。片段将添加到包含<fragment>标记的布局中。除了Views之外,您没有在完全限定的类名后面标记标记。发生此错误是因为Android尝试使用“ListFragment”类型来膨胀View,而该类型不存在。

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>

<fragment>必须为小写,<Fragment>也不会有效。

你混合了一些东西。

1)片段的onCreate方法必须使片段的整个布局膨胀。在膨胀Fragment布局后,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)你没有定义ListView的id,你定义了它的名字。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>
