私はこのようなものを実装しようとしています-見てください。
これは私のBaseAdapterクラスです
public class ImageAdapter extends BaseAdapter {
private Context mContext;
LayoutInflater in = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder view;
if (convertView == null) {
view = new ViewHolder();
convertView = in.inflate(R.layout.country_row, null);
view.txtView = (TextView) convertView
.findViewById(R.id.countryName);
view.txtView.setText(countryName[position]);
convertView.setTag(view);
} else {
view = (ViewHolder) convertView.getTag();
}
view.imgView = (ImageView) convertView.findViewById(R.id.countryImage);
view.imgView.setImageResource(mThumbIds[position]);
return convertView;
}
private Integer[] mThumbIds = { R.drawable.india_flag,
R.drawable.china_flag, R.drawable.argentina_flag,
R.drawable.england_flag, R.drawable.france_flag,
R.drawable.united_states_flag, R.drawable.uruguay_flag,
R.drawable.pakistan_flag, R.drawable.united_kingdom_flag,
R.drawable.italy_flag, R.drawable.germany_flag,
R.drawable.brazil_flag, R.drawable.belgium_flag,
R.drawable.denmark_flag, R.drawable.czech_republic_flag,
R.drawable.jamaica_flag, R.drawable.indonesia_flag,
R.drawable.kenya_flag, R.drawable.korea_flag,
R.drawable.ireland_flag,
};
private String[] countryName = { "India", "China", "Argentina", "England",
"France", "United States", "Uruguay", "Pakistan", "United Kingdom",
"Italy", "Germany", "Brazil", "Belgium", "Denmark",
"Czech Republic", "Jamaica", "Indonesia", "Kenya", "Korea",
"Ireland"
};
public static class ViewHolder {
public ImageView imgView;
public TextView txtView;
}
country_row.xmlには、ImageViewとTextViewが含まれています。
CountriesクラスはFragmentを拡張し、counties.xmlにはGridViewが含まれています(このクラスで何かを台無しにしたと思いますが、修正できませんでした)
public class Countries extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.countries,container,false);
GridView gridView = (GridView) view.findViewById(R.id.myGrid);
gridView.setAdapter(new ImageAdapter(view.getContext()));
return view;
}
}

public class MainActivity extends Activity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

そしてこれは私のlogcatです
