Question

我试图在我的Android应用中实施Admob高级原生广告，无法弄清楚我做错了什么。我将广告放在Listview中。到目前为止，我成功加载了广告，但是当我将代码放在listview中时，它显示错误。这是我提出的代码：

请注意我不会把整个代码只是必要的一部分

Mainactivity

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_awesome);
...
...
...
MobileAds.initialize(getApplicationContext(), getString(R.string.ad_unit_id));

private void loadNativeAd() {


  AdLoader.Builder builder = new AdLoader.Builder(this, getString(R.string.ad_unit_id));
  AdLoader adLoader = builder.forAppInstallAd(new NativeAppInstallAd.OnAppInstallAdLoadedListener() {
  @Override
  public void onAppInstallAdLoaded(NativeAppInstallAd ad) {
  showshort("im ready");

        }

    }).build();

    // Load the Native Express ad.
    adLoader.loadAd(new AdRequest.Builder().build());
}

HomeAdapter

public class HomeAdapter extends ArrayAdapter<String>
{

Context context;

int image[];

String[] title;

String[] description;


public HomeAdapter(Context context, String[] titles, int[] imgs, String[] desc)
{

    super(context, R.layout.single_row,titles);

    this.context=context;

    this.image=imgs;

    this.title=titles;

    this.description=desc;

}

private void populateAppInstallAdView(NativeAppInstallAd nativeAppInstallAd,
                                      NativeAppInstallAdView adView) {


    adView.setHeadlineView(adView.findViewById(R.id.appinstall_headline));
    adView.setBodyView(adView.findViewById(R.id.appinstall_body));
    adView.setCallToActionView(adView.findViewById(R.id.appinstall_call_to_action));
    adView.setIconView(adView.findViewById(R.id.appinstall_app_icon));
    adView.setPriceView(adView.findViewById(R.id.appinstall_price));
    adView.setStarRatingView(adView.findViewById(R.id.appinstall_stars));
    adView.setStoreView(adView.findViewById(R.id.appinstall_store));

    // Some assets are guaranteed to be in every NativeAppInstallAd.
    ((TextView) adView.getHeadlineView()).setText(nativeAppInstallAd.getHeadline());
    ((TextView) adView.getBodyView()).setText(nativeAppInstallAd.getBody());
    ((Button) adView.getCallToActionView()).setText(nativeAppInstallAd.getCallToAction());
    ((ImageView) adView.getIconView()).setImageDrawable(
            nativeAppInstallAd.getIcon().getDrawable());

    // These assets aren't guaranteed to be in every NativeAppInstallAd, so it's important to
    // check before trying to display them.
    if (nativeAppInstallAd.getPrice() == null) {
        adView.getPriceView().setVisibility(View.INVISIBLE);
    } else {
        adView.getPriceView().setVisibility(View.VISIBLE);
        ((TextView) adView.getPriceView()).setText(nativeAppInstallAd.getPrice());
    }

    if (nativeAppInstallAd.getStore() == null) {
        adView.getStoreView().setVisibility(View.INVISIBLE);
    } else {

        adView.getStarRatingView().setVisibility(View.INVISIBLE);
    } else {

                .setRating(nativeAppInstallAd.getStarRating().floatValue());
        adView.getStarRatingView().setVisibility(View.VISIBLE);
    }

    // Assign native ad object to the native view.
    adView.setNativeAd(nativeAppInstallAd);
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    LayoutInflater inflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if (position == 0) {
        View row=inflater.inflate(R.layout.single_home_admob, parent, false);
        populateAppInstallAdView(nativeAppInstallAd, adView);
        return row;
    } else {

    View row=inflater.inflate(R.layout.home_fragment_single_row, parent, false);

    ImageView myimage= (ImageView) row.findViewById(R.id.icon);

    TextView mytitle= (TextView) row.findViewById(R.id.title);

    TextView mydesc= (TextView) row.findViewById(R.id.sub_title);

    myimage.setImageResource(image[position]);

    mytitle.setText(title[position]);

    mydesc.setText(description[position]);

    return row;
