我正在尝试使用适配器在多个片段中创建nested listviews
。我能够在单个活动中创建它,但我不能使用适配器在片段中创建它。将第二个片段作为fragment2引用,将第二个列表作为listview2引用。
package com.example.admin.volleyrequestandresponse.adapter;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.example.admin.volleyrequestandresponse.R;
import com.example.admin.volleyrequestandresponse.activities.NavigationActivity;
import com.example.admin.volleyrequestandresponse.fragments.HomeFragment;
import java.util.ArrayList;
public class HomeFragmentAdapter extends BaseAdapter {
private ArrayList<String> stringArray;
private ArrayList<String> integerArray;
int[] logos;
Context context;
NavigationActivity navigationActivity;
public HomeFragmentAdapter(Context context, ArrayList<String> stringArray, ArrayList<String> integerArray, int[] logos) {
this.context = context;
this.stringArray = stringArray;
this.integerArray = integerArray;
this.logos = logos;
navigationActivity = new NavigationActivity();
}
@Override
public int getCount() {
return integerArray.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.home_adapter, null);
holder = new ViewHolder();
holder.imageview = (ImageView) convertView.findViewById(R.id.indeximg);
holder.txtTitle = (TextView) convertView.findViewById(R.id.indexname);
holder.text = (TextView) convertView.findViewById(R.id.indexvalue);
holder.relativeLayout = (RelativeLayout) convertView.findViewById(R.id.home_adapter);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.imageview.setImageResource(logos[position]);
holder.txtTitle.setText(stringArray.get(position));
holder.text.setText(integerArray.get(position));
return convertView;
}
private class ViewHolder {
RelativeLayout relativeLayout;
TextView text;
TextView txtTitle;
ImageView imageview;
}
}
调用适配器的片段代码
homeFragmentAdapter = new HomeFragmentAdapter(getActivity(),index_string,index_values,index_logo);
listview_HomeFragment.setAdapter(homeFragmentAdapter);
