<!-- Demonstrates using a relative layout to create a form -->
<RelativeLayout xmlns:android="https://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/blue"
android:padding="10dip">
<!--
TextView goes at the top left by default .
-->
<TextView
android:id="@+id/label"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/relative_layout_2_instructions"/>
<!--
Put the EditText field under the TextView
Also give it a standard background (the "android:"
part in @android:drawable/editbox_background
means it is system resource rather than
an application resource.
-->
<EditText
android:id="@+id/entry"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@android:drawable/editbox_background"
android:layout_below="@id/label"/>
<!--
The OK button goes below the EditText field.
It is also aligned to the right edge of the parent
(respecting the parent's padding).
The OK button comes first so the Cancel button
can be specified relative to the OK button.
-->
<Button
android:id="@+id/ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/entry"
android:layout_alignParentRight="true"
android:layout_marginLeft="10dip"
android:text="@string/relative_layout_2_ok" />
<!--
The Cancel button is aligned with the top of
the OK button and positioned to the left of it.
Since the OK button has a left margin of 10, there
is some space between the two buttons.
-->
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/ok"
android:layout_alignTop="@id/ok"
