Is there a way to include one resource in another (for example a header design in multiple activities' layouts). I know I can add it at run time, can it be done in the XML?

A:
Yes you can do this in XML. See the android docs about merge/include
basically you would have 1 layout(root.xml
) as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rootLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="@+id/headingLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<include
android:layout_width="wrap_content"
android:layout_height="wrap_content"
layout="@layout/heading_layout" />
</LinearLayout>
<RelativeLayout>
and the heading_layout.xml
:
<?xml version="1.0" encoding="utf-8"?>
<merge
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/titleImg"
android:src="@drawable/bg_cell"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/titleTxt"
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
</merge>
so in your Activity
you would setContentView(R.layout.root);
which would include the header.
you can also do some cool stuff in addition to this programmatically, such as inserting a layout from xml into a the root.xml
(after setContentView();
:
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.home, rootLayout);
where rootLayout
is the parent RelativeLayout
found by id and R.layout.home
is a layout you wish to add to the root
