注：我试过减少targetSdkVersion至10。然而，我得到的错误。请帮帮忙！

编辑：我不明白为什么它称为 AbsListVew 的时候，我都用了一个的ListView 。另外请注意，我用一个自定义的适配器。

EventListAdapter 扩展 ArrayAdaptere＆LT;的listContent＆GT; 键，显示NO ERROR

为您的网站引用是XML布局code段为R.id.ListView1

 ＆LT;的ListView
        机器人：layout_margin =10dp
        机器人：dividerHeight =10.0sp
        机器人：ID =@ + ID / ListView1的
        机器人：layout_width =FILL_PARENT
        机器人：layout_height =FILL_PARENT/＆GT;

I'm calling the setAdapter() method in a class that extends Fragment. Note that I have imported android.support.v4.app.Fragment .

However I get an error stating that the API level is required to be level 11.

What do I have to do so that I can fix this without changing minSdkVersion="8" to 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
        }
    }
}

Note : I tried reducing the targetSdkVersion to 10. Yet I get the error. Please help!

Edit : I don't understand why it's termed as AbsListVew when all that I have used is a ListView. Also, note that I've used a custom adapter.

EventListAdapter extends ArrayAdaptere<ListContent> and shows NO ERROR.

For your reference here is the xml layout code snippet for R.id.ListView1

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

解决方案

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

"Run Android Lint" makes some markers and the markers cause this error.
