Update TextView in inflated Layout

I have a template layout file called

template_dashboard_item.xml

its contents are

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/DashboardItemContainer">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/DashboardItem">
    <TextView style="@style/DashboardItemText" android:text="Application for Jane Doe has been added" android:textColor="@color/black" />
    <TextView style="@style/DashboardItemText" android:text="Added today at ..." android:layout_marginTop="10dp" />                 
</LinearLayout>

I am using this template layout by inflating it and inserting it into a view like so

LinearLayout item = (LinearLayout) getLayoutInflater().inflate(R.layout.template_dashboard_item, items, false);
items.addView(item);

Like that, I am inserting it multiple times.

I would like to know, before I insert it (addView) how to I update the TextViews (text) that are there ?

In other words how do I fetch the objects for the TextView ? (I guess findViewById would not work in this case).

Why dont you create a custom layout like this 

public class CustomView extends RelativeLayout {

    private TextView header;
    private TextView description;



    public Card(Context context) {
        super(context);
        init();
    }

    public Card(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public Card(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        inflate(getContext(), R.layout.view_layout, this);
        this.header = (TextView) findViewById(R.id.header);
        this.description = (TextView) findViewById(R.id.description);
    }


    public void setHeader(String header) {
        this.header.setText(header);
    }


    public void setDescription(String description) {
        this.description.setText(description);
    }

}

And to add the layout 

LinearLayout items = (LinearLayout) getLayoutInflater().inflate(R.layout.template_dashboard_item, items, false);
CustomView item = new CustomView(this);
item.setHeader("xxx);
item.setDescription("yyy");
items.addView(item);

you can either assign an id to the TextViews and use item.findViewById to retrieve it, or use ViewGroup.getChildAt(int index)

 for (int i = 0 i < item.getChildCount(); i++) {
         View view = item.getChildAt(i);
         if (view instanceof TextView) {

         }
  }

Why can't you add an id to your two text views in the XML and use TextView text = item.findViewById(R.id.your_id);
