                container, false);
        ListView listview = (ListView) rootView.findViewById(R.id.listView1);
        String[] items = new String[] { "Item 1", "Item 2", "Item 3" };
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1, items);

Please check below link for creating custom listview in android.

Edited : Added simple example for fragments. Here I have added call data to custom adapter.

This is fragment class :

import java.util.ArrayList;
import java.util.HashMap;

import adapter.CustomCallLogListAdapter;
import android.annotation.SuppressLint;
import android.content.CursorLoader;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.CallLog;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;

import com.broadcast.myblocklist.R;

public class CallLogFragment extends Fragment
{
    private View view;
    private ListView list_calllog;
    private ArrayList<HashMap<String,String>> callLog;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    {
        if(view==null)
        {
            view=inflater.inflate(R.layout.fragment_call_log_layout, container,false);
        }   
        else
        {
            ViewGroup parent = (ViewGroup) view.getParent();
            parent.removeView(view);
        }   

        callLog=getCallLog();
        CustomCallLogListAdapter adapter=new CustomCallLogListAdapter(getActivity(),R.layout.row_call_log_layout,callLog);
        list_calllog=(ListView)view.findViewById(R.id.list_calllog);
        list_calllog.setAdapter(adapter);
        return view;
    }

    @SuppressLint("NewApi")
    public ArrayList<HashMap<String,String>> getCallLog()
    {
        ArrayList<HashMap<String,String>> callLog=new ArrayList<HashMap<String,String>>();
        CursorLoader cursorLoader=new CursorLoader(getActivity(),CallLog.Calls.CONTENT_URI, null, null, null, null);
        Cursor cursor=cursorLoader.loadInBackground();
        if(cursor.moveToFirst())
        {
            while (cursor.moveToNext())
            {
                HashMap<String,String> hashMap=new HashMap<String, String>();
                hashMap.put(CallLog.Calls.NUMBER, cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER)));
                hashMap.put(CallLog.Calls.DATE, cursor.getString(cursor.getColumnIndex(CallLog.Calls.DATE)));
                hashMap.put(CallLog.Calls.DURATION, cursor.getString(cursor.getColumnIndex(CallLog.Calls.DURATION)));   
                callLog.add(hashMap);
            }
        }
        return callLog;
    }
}

Custom Adapter class :

import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;

import android.content.Context;
import android.provider.CallLog;
import android.text.format.DateFormat;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

import com.broadcast.myblocklist.R;

public class CustomCallLogListAdapter extends ArrayAdapter<HashMap<String,String>>
{
    private ArrayList<HashMap<String,String>> callLogData;
    private Context context;
    private int resource;
    private View view;
    private Holder holder;
    private HashMap<String,String> hashMap;
    public CustomCallLogListAdapter(Context context, int resource,ArrayList<HashMap<String, String>> objects) 
    {
        super(context, resource, objects);
        this.context=context;
        this.resource=resource;
        this.callLogData=objects;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) 
    {

        LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view=inflater.inflate(resource, parent,false);

        holder=new Holder();
        holder.text_number=(TextView)view.findViewById(R.id.text_calllog_number);
        holder.text_date=(TextView)view.findViewById(R.id.text_calllog_date);
        holder.text_time=(TextView)view.findViewById(R.id.text_calllog_time);

        hashMap=callLogData.get(position);      

        Date date=new Date(Long.parseLong(hashMap.get(CallLog.Calls.DATE)));
        java.text.DateFormat dateFormat=DateFormat.getDateFormat(context);
        java.text.DateFormat timeformat=DateFormat.getTimeFormat(context);


        holder.text_number.setText(hashMap.get(CallLog.Calls.NUMBER));
        holder.text_time.setText(timeformat.format(date));
        holder.text_date.setText(dateFormat.format(date));

        return view;
    }

    public class Holder
    {
        TextView text_number;
        TextView text_date;
        TextView text_time;
    }

}

Adapter Item layout :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="@dimen/activity_horizontal_margin"
    android:layout_marginLeft="@dimen/activity_vertical_margin"
    android:layout_marginRight="@dimen/activity_vertical_margin"
    android:layout_marginTop="@dimen/activity_horizontal_margin" >

    <TextView
        android:id="@+id/text_calllog_number"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:textStyle="bold" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/text_calllog_number"
        android:layout_marginTop="5dp"
        android:orientation="horizontal" >

        <TextView
            android:id="@+id/text_calllog_date"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" />

        <TextView
            android:id="@+id/text_calllog_time"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" />
    </LinearLayout>

</RelativeLayout>

and fragment layout :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

   <ListView 
       android:id="@+id/list_calllog"
       android:layout_width="match_parent"
       android:layout_height="match_parent"></ListView>

</LinearLayout>

This is more than you want. You can customize it as you want.Put your custom data to list to fill ArrayList. Just use it as base example.!!

Hope It will help.
