我想在列表视图中使用适配器类添加搜索栏，任何人都可以帮我下面是我的代码。 这是我正在使用的适配器类。 Cat_Headers_Home_Adapter.java
public class Cat_Headers_Home_Adapter extends SectionAdapter {
private Activity cntx;
private List<Categories> categoriesList;
private List<CatHeaders> categoriesHeadersList;
public Cat_Headers_Home_Adapter(Activity cntx,List<Categories>categoriesList, List<CatHeaders> categoriesHeadersList) {
this.cntx = cntx;
this.categoriesList = categoriesList;
this.categoriesHeadersList = categoriesHeadersList;
}
@Override
public int numberOfSections() {
return categoriesHeadersList.size();
}
@Override
public int numberOfRows(int section) {
return categoriesList.size();
}
@Override
public Object getRowItem(int section, int row) {
return null;
}
@Override
public boolean hasSectionHeaderView(int section) {
return true;
}
@Override
public View getRowView(int section, int row, View convertView, ViewGroup parent) {
View view = convertView;
Holder holder;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) cntx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.adapter_home_service_cat, null);
holder = new Holder();
view.setTag(holder);
} else {
holder = (Holder) view.getTag();
}
Categories categories = categoriesList.get(section);
holder.service_name = (TextView) view.findViewById(R.id.service_name);
holder.count = (TextView) view.findViewById(R.id.total);
holder.service_icon = (ImageView) view.findViewById(R.id.service_icon);
holder.service_layout = (LinearLayout)view.findViewById(R.id.service_layout);
holder.service_name.setText(categories.catName);
holder.count.setText(categories.count);
holder.service_icon.setImageResource(categories.catImage);
holder.service_layout.setVisibility(View.VISIBLE);
return view;
}
private class Holder {
TextView service_name;
TextView count;
ImageView service_icon;
LinearLayout service_layout;
}
@Override
public int getSectionHeaderViewTypeCount() {
return 2;
}
@Override
public int getSectionHeaderItemViewType(int section) {
return section % 2;
}
@Override
public View getSectionHeaderView(int section, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = (TextView) cntx.getLayoutInflater().inflate(cntx.getResources().getLayout(android.R.layout.simple_list_item_1), null);
}
((TextView) convertView).setText(categoriesHeadersList.get(section).catName);
((TextView) convertView).setTextColor(cntx.getResources().getColor(android.R.color.white));
convertView.setBackgroundColor(cntx.getResources().getColor(R.color.red));
return convertView;
}
@Override
public void onRowItemClick(AdapterView<?> parent, View view, int section, int row, long id) {
super.onRowItemClick(parent, view, section, row, id);
Toast.makeText(cntx, "Section " + section + " Row " + row, Toast.LENGTH_SHORT).show();
}
}
这是一个我想在其上添加搜索栏的班级 Home_fragment.java

// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("position", index);
f.setArguments(args);

}
