setAdapter"调用需要API级别11(当前最小值为8):android.widget.AbsListView #setAdapter"？

Question

我setAdapter()在一个扩展的类中调用该方法Fragment.请注意,我已导入android.support.v4.app.Fragment.

但是我收到一个错误,指出API级别必须是11级.

我有什么做的,这样我可以解决这个问题不改变minSdkVersion="8",以minSdkVersion="11"

package foo.bar.qux;

import java.util.Calendar;
import java.util.Date;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;

import android.support.v4.app.Fragment;

import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;

public class TabFragmentList extends Fragment {

    String category, xml;
    NodeList nodes;
    int numResults;
    private ListView lv;
    Date date;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        if (container == null) return null;
        return (LinearLayout) inflater.inflate(R.layout.eventlist, container,
                false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        Activity activity = getActivity();
        if (activity != null) {
            final Calendar c = Calendar.getInstance();
            ListContent[] item = new ListContent[3];
            category = (String) activity.getIntent().getExtras()
                    .get("category");
            xml = (String) activity.getIntent().getExtras().get("xml");
            TextView tv = (TextView) getView().findViewById(R.id.category);
            tv.setText(category);
            nodes = doc.getElementsByTagName("event");
            for (int i = 0; i < 3; i++) {
                c.add(Calendar.DATE, 1);
                date = c.getTime();
                item[i] = new ListContent();
                item[i].setList(nodes, category, date);
            }
            EventListAdapter adapter = new EventListAdapter(activity,
                    R.layout.eventlist_row, item);
            lv = (ListView) getView().findViewById(R.id.listView1);
            lv.setAdapter(adapter); // ERROR SHOWN HERE
        }
    }
}

注意:我尝试将targetSdkVersion减少到10.但是我得到了错误.请帮忙!

编辑:我不明白为什么它被称为AbsListVew当我使用的所有东西都是ListView.另外,请注意我使用了自定义适配器.

EventListAdapter延伸ArrayAdaptere<ListContent>并显示无错误.

这里是R.id.ListView1的xml布局代码片段供您参考

<ListView
        android:layout_margin="10dp"
        android:dividerHeight="10.0sp"
        android:id="@+id/listView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

Answer 1

Right click on the project folder > Android tools > Clear Link Markers

"运行Android Lint"会使一些标记和标记导致此错误.

Answer 2

解决方案只是转换类型以更正子类型,因为后来Android版本引入了具有相同名称的方法调用.

@SuppressWarnings({ "unchecked", "rawtypes" })

EventListAdapter adapter = new EventListAdapter(activity, R.layout.eventlist_row, item);
lv = (ListView) getView().findViewById(R.id.listView1);
((AdapterView)lv).setAdapter(adapter); //ERROR SOLVED HERE
