[android] Android - Dynamically Add Views into View

I have a layout for a view -

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="0px"
    android:orientation="vertical">

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/items_header"
        style="@style/Home.ListHeader" />

    <TextView 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/items_none"
        android:visibility="gone"
        style="@style/TextBlock"
        android:paddingLeft="6px" />

    <ListView 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/items_list" />


</LinearLayout>

What I want to do, is in my main activity with a layout like this

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="0px"
    android:id="@+id/item_wrapper">
</LinearLayout>

I want to loop through my data model and inject multiple views consisting of the first layout into the main layout. I know I can do this by building the controls completely within the code, but I was wondering if there was a way to dynamically build the views so that I can continue using a layout instead of putting everything in code.

To make @Mark Fisher's answer more clear, the inserted view being inflated should be a xml file under layout folder but without a layout (ViewGroup) like LinearLayout etc. inside. My example:

res/layout/my_view.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/i_am_id"
    android:text="my name"
    android:textSize="17sp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"/>

Then, the insertion point should be a layout like LinearLayout:

res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/aaa"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/insert_point"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </LinearLayout>

</RelativeLayout>

Then the code should be

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_shopping_cart);

    LayoutInflater inflater = getLayoutInflater();
    View view = inflater.inflate(R.layout.my_view, null);
    ViewGroup main = (ViewGroup) findViewById(R.id.insert_point);
    main.addView(view, 0);
}

The reason I post this very similar answer is that when I tried to implement Mark's solution, I got stuck on what xml file should I use for insert_point and the child view. I used layout in the child view firstly and it was totally not working, which took me several hours to figure out. So hope my exploration can save others' time.

It looks like what you really want a ListView with a custom adapter to inflate the specified layout. Using an ArrayAdapter and the method notifyDataSetChanged() you have full control of the Views generation and rendering.

Take a look at these tutorials

See the LayoutInflater class.

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ViewGroup parent = (ViewGroup)findViewById(R.id.where_you_want_to_insert);
inflater.inflate(R.layout.the_child_view, parent);

// Parent layout
LinearLayout parentLayout = (LinearLayout)findViewById(R.id.layout);

// Layout inflater
LayoutInflater layoutInflater = getLayoutInflater();
View view;

for (int i = 1; i < 101; i++){
    // Add the text layout to the parent layout
    view = layoutInflater.inflate(R.layout.text_layout, parentLayout, false);

    // In order to get the view we have to use the new view with text_layout in it
    TextView textView = (TextView)view.findViewById(R.id.text);
    textView.setText("Row " + i);

    // Add the text view to the parent layout
    parentLayout.addView(textView);
}
