我一整天都在尝试让 ListView 在 fragment 中工作。我不知道为什么，但出于某种原因，我尝试这样做的方式，它只是不想夸大 View 。如果这有所作为，我会使用 actionbarsherlock，但我不这么认为。这是我的布局失败的类:
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
}
这是我称之为 fragment 的布局。
<?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>
我尝试了几种不同的设置，来回使用常规 fragment 和列表 fragment ，结果相同。这是 logcat。

最佳答案
您布局中的 fragment 导入错误。使用 <fragment> 将 fragment 添加到布局中标签。除了 Views您没有在完全限定的类名之后命名标签。发生错误是因为 Android 试图膨胀 View类型为“ListFragment”，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>必须小写，<Fragment>也行不通。
你混淆了一些东西。
1) onCreate fragment 的方法必须膨胀 fragment 的整个布局。充气后 Fragment您可以获得 ListView 的布局。
@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 ，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>
