Android: How to dynamically include a XML Layout?

Question

I want to decompose my UI into several XML Layouts. The first one would be the main layout, and the other ones would be the content layouts.

I would like to be able to set which content_layout should be included dynamically at run-time, so I don't want to set a "layout="@+layout/content_layout" in my XML file.

Here are my layouts:

main_layout.xml:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="600dp"     android:layout_height="800dp" >      <TextView         android:id="@+id/title"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_alignParentTop="true" />      <include /> <!-- I WANT TO INCLUDE MY CONTENT HERE -->      <Button         android:id="@+id/cancelButton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignParentBottom="true"         android:layout_centerHorizontal="true"         android:text="Cancel" />  </RelativeLayout> 

content_layout.xml:

<?xml version="1.0" encoding="utf-8"?> <ListView xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/whatever"     android:layout_height="wrap_content"     android:layout_width="fill_parent" /> 

content_layout2.xml:

<?xml version="1.0" encoding="utf-8"?> <ListView xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/whatever2"     android:layout_height="wrap_content"     android:layout_width="fill_parent" /> 

How can I do that?

Thanks!

Answer 1

<RelativeLayout android:id="@+id/rl" ... 

In your code:

// get your outer relative layout RelativeLayout rl = (RelativeLayout) findById(R.id.rl);   // inflate content layout and add it to the relative layout as second child // add as second child, therefore pass index 1 (0,1,...)  LayoutInflater layoutInflater = (LayoutInflater)          this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);     rl.addView(1, layoutInflater.inflate(R.layout.content_layout, this, false) );  

Answer 2

You could try using a ViewStub and just change which layout it is going to inflate programatically.

This answer discusses using one ViewStub.
