这是在getView（）中通货膨胀时的CountryDrawerListAdapter我得到java.lang.RuntimeException：二进制XML文件行＃10：你必须提供layout_width属性。
public class CountryDrawerListAdapter extends BaseAdapter implements Filterable {
private Context mContext;
private LayoutInflater mLayoutInflater;
private Viewholder mHolder;
private InputStream mInputStream = null;
private ItemFilter mFilter = new ItemFilter();
private List<String> mFilteredData = null;
private ArrayList<String> mData;
public CountryDrawerListAdapter(Context context, ArrayList<String> data, ListView list) {
this.mContext =context;
this.mFilteredData =data;
this.mData =data;
mLayoutInflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
private static class Viewholder {
TextView text;
ImageView icon;
CheckBox ch_box;
}
@Override
public int getCount() {
if (mFilteredData ==null) {
return 0;
}
else return mFilteredData.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
if (convertView == null) {
vi = mLayoutInflater.inflate(R.layout.a_clientslist_layout, null);
mHolder = new Viewholder();
mHolder.text = (TextView) vi.findViewById(R.id.tv_client_name);
mHolder.icon = (ImageView) vi.findViewById(R.id.img_client_logo);
vi.setTag(mHolder);
}
else {
mHolder = (Viewholder) vi.getTag();
}
mHolder.text.setText(mFilteredData.get(position));
Drawable d;
try {
String flags=null;
/* "images/client_1.png"*/
if(mFilteredData.get(position).length()>0)
{
flags= mFilteredData.get(position).replaceAll(" ", "_");
}
d = Drawable.createFromStream(mContext.getAssets().open("flags/"+flags+".png"), null);
if (d==null){
mHolder.icon.setImageResource(R.drawable.ic_launcher);
}
mHolder.icon.setBackground(d);
} catch (IOException e) {
LogCat.e("IOException", "" + e.toString());
}
return vi;
}
public Filter getFilter() { return mFilter;
}
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final List<String> list = mData;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
mFilteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
}
这是将由适配器充气的Xml。
<?xml version="1.0" encoding="utf-8"?>

这是我的日志Cat显示错误。
