ViewPager片段
ViewPager fragment
public class ViewPage extends Fragment {
// Declare Variables
ViewPager viewPager;
ViewPagerAdapter adapter;
Uebung.SessionItemAdapter adapter2;
String[] Titel;
ImageButton btnswipeview;
List<String> data = new ArrayList<String>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from viewpager_main.xml
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View layout = inflater.inflate(R.layout.viewpage, container, false);
ArrayList<String> strtext=getArguments().getStringArrayList("key");
String frnames[]=strtext.toArray(new String[strtext.size()]);
Titel = frnames;
// Locate the ViewPager in viewpager_main.xml
viewPager = (ViewPager) layout.findViewById(R.id.viewPager);
// Pass results to ViewPagerAdapter Class
adapter = new ViewPagerAdapter(getActivity(), Titel);
// Binds the Adapter to the ViewPager
viewPager.setAdapter(adapter);
return layout;
}
ViewPagerAdapter
ViewPagerAdapter

final EditText editText = (EditText) itemView.findViewById(R.id.editTextswipeView);
Button btnswipeview = (Button) itemView.findViewById(R.id.imagebuttonswipeview);
listItems = new ArrayList<String>();
listItems.add("First Item - added on Activity Create");
adapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, listItems);
listView.setAdapter(adapter);
btnswipeview.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View View) {
Toast toast = Toast.makeText(context,
"You clicked the button",
Toast.LENGTH_SHORT);
toast.show();
listItems.add(editText.getText().toString());
adapter.notifyDataSetChanged();
}
});
return itemView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
// Remove viewpager_item.xml from ViewPager
((ViewPager) container).removeView((LinearLayout) object);
}
}
swipeview.xml
swipeview.xml
<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="numberDecimal"
android:ems="10"

<Button

</LinearLayout>
<LinearLayout

android:layout_weight="1">
<ListView
android:layout_margin="5dp"
android:id="@+id/listViewswipeview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:clickable="true"
android:drawSelectorOnTop="true"
android:focusable="true"
android:choiceMode="singleChoice"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/spinnerswipeview"
android:entries="@array/day"
android:layout_gravity="center_horizontal"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
这将是很好，如果有人编辑code到FragmentStatePAgerAdapter或将我解释，我必须对其进行编辑。
It would be nice if someone edit the code to a FragmentStatePAgerAdapter or would me explain how I must edit it.
在此先感谢。
推荐答案
FragmentStatePagerAdapter 是子类 PagerAdapter 的，所以你需要让你的 ViewPagerAdapter 类直接从 FragmentStatePagerAdapter 延伸，而不是从 PagerAdapter 。
FragmentStatePagerAdapter is a child class of PagerAdapter, so you need to make your ViewPagerAdapter class extend directly from FragmentStatePagerAdapter, not from PagerAdapter.
