带有自定义适配器的Android DrawerLayout和Listview

对于listview,我创建了一个自定义适配器,我使用list_item xml文件创建每一行,该文件具有imageview和textview.

该应用程序运行,但当我打开抽屉时,我只看到没有列表视图的背景.
现在,如果我使用ArrayAdapter(默认)尝试它,列表视图就会显示出来.

有什么建议？

我的定制适配器

public class CustomAdapter extends ArrayAdapter<Categories>{

Context context;
int layoutresourcEID;
Categories[] data = null;

public CustomAdapter(Context context,int layoutresourcEID,Categories[] categs) {
    super(context,layoutresourcEID);
    this.layoutresourcEID = layoutresourcEID;
    this.context = context;
    data = categs;
}


@Override
public View getView(int position,View convertView,ViewGroup parent) {
    View row = convertView;
    PHolder holder = null;

    if(row == null)
    {
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        row = inflater.inflate(layoutresourcEID,parent,falsE);

        holder = new PHolder();
        holder.imgIcon = (ImageView)row.findViewById(R.id.categimagE);
        holder.txttitle = (TextView)row.findViewById(R.id.categtext);

        row.setTag(holder);
    }
    else
    {
        holder = (PHolder)row.getTag();
    }

    Categories categ = data[position];
    holder.txttitle.setText(categ.titlE);
    holder.imgIcon.setImageresource(categ.icon);

    return row;
}

static class PHolder
{
    ImageView imgIcon;
    TextView txttitle;
}

}

在我的主要活动中

@H_780_16@mDrawerList = (ListView) findViewById(R.id.categlist); Categories data[] = new Categories[] { new Categories(R.drawable.restaurant,R.String.food),new Categories(R.drawable.bar_coktail,R.String.bar),new Categories(R.drawable.mall,R.String.shop),new Categories(R.drawable.agritourism,R.String.out),new Categories(R.drawable.dance_class,R.String.art),new Categories(R.drawable.officebuilding,R.String.other),new Categories(R.drawable.university,R.String.education),new Categories(R.drawable.townhouse,R.String.housE),new Categories(R.drawable.junction,R.String.transport) }; CustomAdapter ca = new CustomAdapter(this,R.layout.list_item,data); View header = (View)getLayoutInflater().inflate(R.layout.list_header,null); mDrawerList.addHeaderView(header); mDrawerList.setAdapter(ca);
