How to show Multiple Headings and Points in Single Activity

I am following this SO solution, and i have successfully parsed JSON, but don't know How to show both the headings and points in TextViews.

this is how my JSON looks:

{
    "technology": [
        {
            "title": "Android",
            "description": [
                {
                    "heading": "Manufactures",
                    "points": [
                        "Google",
                        "Samsung"
                    ]
                },
                {
                    "heading": "Platforms",
                    "points": [
                        "Kitkat",
                        "ICS"
                    ]
                }
            ]
        }
    ] 
}

For an example, if i do tap on Android, then i want to show something like this:

Manufactures
[dot] Google
[dot] Samsung

Platforms
[dot] Kitkat
[dot] ICS

For reference see this images:

In place of Why We Like It, i want to show Manufactures and in place of Need to Know, i want to show Platforms (with their respective points) as shown in Image.

But getting something like this:

Platforms
[dot] ICS

So what is the reason? and where i have to make changes in my code ?

DescriptionActivity.java:-

 arrayListDescription = technology.getDescription();

    for(int s=0; s<arrayListDescription.size(); s++)
    {
        description = arrayListDescription.get(s);
        strHeading = description.getHeading();
        Log.d("heading::", strHeading);
        arrayListPoints = description.getPoints();      

        for(int z=0; z<arrayListPoints.size(); z++)
        {
            strPoints = "&emsp;&middot;" + arrayListPoints.get(z) + "\n";
            Log.d("points::", strPoints);
        }
        textViewPoints.setText(Html.fromHtml(strPoints));
    }       

    textViewHeading.setText(strHeading);
    textViewHeading.setTextSize(24);

}

activity_description.xml:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://ift.tt/nIICcg"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textHeading"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

    <TextView
        android:id="@+id/textPoints"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

</LinearLayout>

this is what my Log says:

08-28 04:47:39.653: D/heading::(1902): Manufactures
08-28 04:47:39.653: D/points::(1902):  ·Google
08-28 04:47:39.671: D/points::(1902):  ·Samsung
08-28 04:47:39.761: D/heading::(1902): Platforms
08-28 04:47:39.761: D/points::(1902):  ·Kitkat
08-28 04:47:39.761: D/points::(1902):  ·ICS
