В Фрагменте просмотр списка не отображается. Вот мой код. Пытаясь решить эту проблему ....Просмотр списка не отображается в Фрагменте

Я зову LeaderList.java от LeaderShip.java, который для заполнения framelayout.I звоню LeaderShip.java из другого фрагмента ...

Я не уверен, попробуйте переопределить 'getCount()' в вашем 'ArrayAdapter' – SathishKumar

. Пожалуйста, переопределите метод getcount, тогда он будет work –

LeaderList. java

package com.example.listviewtest; 

import android.app.Activity; 
import android.graphics.Color; 
import android.graphics.Typeface; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.ImageButton; 
import android.widget.ImageView; 
import android.widget.TextView; 



public class LeaderList extends ArrayAdapter<String> { 

    private final Activity context; 
    private final int web; 
    private final Integer[] expandImage; 
    private final Integer[] mailImage; 
    private final Integer[] phoneImage; 
    private final Integer[] twitterImage; 
    private final Integer[] personalImage; 
    private final String [] Title; 

    ImageButton imageButton; 

    //private final Integer[] imageId; 
    public LeaderList(Activity context, 
    int web,Integer [] personalImage, Integer [] mailImage,Integer [] phoneImage, 
    Integer [] twitterImage,Integer [] expandImage,String [] Title) { 
    super(context,web); 
    this.context = context; 
    this.web = web; 
    this.personalImage = personalImage; 
    this.mailImage = mailImage; 
    this.phoneImage = phoneImage; 
    this.twitterImage = twitterImage; 
    this.expandImage = expandImage; 
    this.Title = Title; 
    } 
    @Override 
    public View getView(int position, View view, ViewGroup parent) { 
     LayoutInflater inflater = context.getLayoutInflater(); 
     View convertView= inflater.inflate(R.layout.leadership, parent, false); 

     TextView lblListHeader = (TextView) convertView.findViewById(R.id.ShowLeadTitle); 
     ImageView imageview = (ImageView) convertView.findViewById(R.id.representative); 
     ImageButton mailimageview = (ImageButton) convertView.findViewById(R.id.mailimg); 
     ImageButton phoneimageview = (ImageButton) convertView.findViewById(R.id.phoneimg); 
     ImageButton twitterimageview = (ImageButton) convertView.findViewById(R.id.twitterimg); 
     ImageButton expandimageview = (ImageButton) convertView.findViewById(R.id.arrowimg); 

     lblListHeader.setTypeface(null, Typeface.BOLD); 
     lblListHeader.setTextColor(Color.WHITE); 
     imageview.setImageResource(personalImage[position]); 
     mailimageview.setImageResource(mailImage[position]); 
     phoneimageview.setImageResource(phoneImage[position]); 
     twitterimageview.setImageResource(twitterImage[position]); 
     expandimageview.setImageResource(expandImage[position]); 

     return convertView; 
    } 

@Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return 1; 
    } 

}

Попробуйте и скажите.
