Nesting XML layouts

How to load XML layout file dynamically?

Here is a sample code to load two XML layout file in one java activity class.

layout_1.xml is main XML file, which has a placeholder at the bottom. This placeholder is used to show the content of second xml file.

layout_1.xml

<?xml version=”1.0″ encoding=”UTF-8″?>

<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android&#8221;

android:orientation=”vertical”

android:layout_width=”fill_parent”

android:layout_height=”fill_parent” >

<TextView android:id=”@+id/box_0″

android:layout_width=”fill_parent”

android:layout_height=”40px”

android:background=”@drawable/blue”

android:text=”This is main layout” />

<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android&#8221;

android:id=”@+id/box_1″

android:layout_width=”fill_parent”

android:layout_height=”wrap_content”

android:layout_below=”@+id/box_0″ >

</LinearLayout>

</RelativeLayout>

In above code box_1 is the placeholder. Now take a look at second layout.

layout_2.xml

<?xml version=”1.0″ encoding=”UTF-8″?>

<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android&#8221;

android:id=”@+id/box”

android:orientation=”horizontal”

android:layout_width=”fill_parent”

android:layout_height=”fill_parent”  >

<TextView android:id=”@+id/box_0″

android:layout_width=”fill_parent”

android:layout_height=”40px”

android:background=”@drawable/yellow”

android:text=”This is second layout” />

</LinearLayout>

And below is the java code to load both layouts.

Java code

setContentView(R.layout.itest);

LinearLayout ll = (LinearLayout) findViewById(R.id.box_1);

View vv = View.inflate(PrivacySettings.this, R.layout.itest2, null);

ll.addView(vv, new LinearLayout.LayoutParams( ll.getLayoutParams().width,

ll.getLayoutParams().height));
