You need to create a CustomArrayAdapter and pass both the arrays to that adapter.

Override getView method in adapter which gives you position based on it create a view with two textviews and set them respectively.

Follow this for more info on customArrayAdapter:

Before coding pls read the below

How ListView's recycling mechanism works

http://developer.android.com/training/improving-layouts/smooth-scrolling.html

You can use a Custom Adapter

listview.setAdapter (new CustomAdapter(ActivityName.this,R.layout.customlayout,pub,headlines));

Then

public class CustomAdapter extends ArrayAdapter
{

  ArrayList<String> pub,headlines;
  LayoutInflater mInlfater;   
  public CUstomAdapter(Context context,int layout,ArrayList<String> pub,ArrayList<String> headlines)
  {
      super(context,layout,pub);
      mInflater = LayoutInflater.from(context);
      this.pub= pub;
      this.headlines = headlines;  
  }
  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
   ViewHolder holder; 

   if (convertView == null) {
    convertView = mInflater.inflate(R.layout.list_row, parent,false);
    holder = new ViewHolder();
    holder.tv1 = (TextView) convertView.findViewById(R.id.textView1);
    holder.tv2 = (TextView) convertView.findViewById(R.id.textView2);
    convertView.setTag(holder);
   }
   else {
    // view already exists, get the holder instance from the view
    holder = (ViewHolder) convertView.getTag();
   }
    holder.tv1.setText(pub.get(position).toString());
    holder.tv2.setText(headlines.get(position).toString());
    return convertView
   }
    static class ViewHolder {
      TextView tv1;
      TextView tv2;

    }  

}

list_item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="32dp"
        android:layout_marginTop="44dp"
        android:text="TextView" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/textView1"
        android:layout_alignParentRight="true"
        android:layout_marginRight="64dp"
        android:text="TextView" />

</RelativeLayout>

@Viren you have 2 textview in the given code above and set the adapter to listview. `list_item.xml` has 2 textviews. You have a Custom adapter set to listview. What else do you want?? – Raghunandan Jun 13 '14 at 09:40
in my first post code what i have to call in oncreate list_item or my listview xml? – veer1987 Jun 13 '14 at 09:44
@Viren you have to set the content of the layout which has to listview to the activity. Then in your cusotm adapter inflate a layout which has 2 textviews. This is already shown in my post. – Raghunandan Jun 13 '14 at 09:45
@Viren SO is not mailing... Pls understand the working code provided. Nobody will mail. – Raghunandan Jun 13 '14 at 09:46
ok,just tell me in custome adapter i have call list_item.xml and in the above post code how i call,is there any listview.xml file need to create,which file will load data,only setlistadapter will load data? – veer1987 Jun 13 '14 at 09:49
@Viren you read about custom adapters first. Adapter acts as a bridge between your data and the listview. setAdapter set the adapter to listview. Now what is your problem?? – Raghunandan Jun 13 '14 at 09:55
i load data in listview are in two language it may be gujarati and may be english for listview,english are load successfully but gujarati not load(boxes are seen) so how would i load gujarati as well.can i do this with put gujarati font in assets folder,how to do this pls help... – veer1987 Jun 13 '14 at 10:12
@Viren read about localization. If the language is not supported by android you need to use a some other work around. pls ask a new question reagarding the same. – Raghunandan Jun 13 '14 at 10:15
