如果您获取最新的 Facebook Android SDK，您可以找到 NativeAdSample 项目，该项目更新了如何在 ListView 中显示原生广告。从示例中复制的代码:

package com.facebook.samples.NativeAdSample;

import java.util.ArrayList;
import java.util.List;

import com.facebook.ads.Ad;
import com.facebook.ads.AdError;
import com.facebook.ads.AdListener;
import com.facebook.ads.NativeAd;

import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class NativeAdListActivity extends ListActivity implements AdListener {

    private ListView listView;
    private ListViewAdapter adapter;
    private NativeAd listNativeAd;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        listNativeAd = new NativeAd(this, "YOUR_PLACEMENT_ID");
        listNativeAd.setAdListener(this);
        listNativeAd.loadAd();

        listView = getListView();
        adapter = new ListViewAdapter(getApplicationContext());
        listView.setAdapter(adapter);
    }

    @Override
    public void onAdClicked(Ad ad) {
        Toast.makeText(this, "Ad Clicked", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onAdLoaded(Ad ad) {
        adapter.addNativeAd((NativeAd) ad);
    }

    @Override
    public void onError(Ad ad, AdError error) {

                return (View) list.get(position);
            } else {

                } else {
                    view = (TextView) inflater.inflate(R.layout.list_item, parent, false);
                }
                view.setText((String) list.get(position));
                return view;
            }
        }

        public synchronized void addNativeAd(NativeAd ad) {
            if (ad == null) {
                return;
            }
            if (this.ad != null) {
                // Clean up the old ad before inserting the new one
                this.ad.unregisterView();
                this.list.remove(AD_INDEX);
                this.ad = null;
