code dynamic so that it can be displayed in all devices.

  <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<ImageView
    android:id="@+id/ivReturnedPic"
    android:layout_width="fill_parent"
    android:layout_height="250dp"
    android:layout_gravity="center"
    android:src="@drawable/back" />

<Button
    android:id="@+id/ibtakePic"
    android:layout_width="125dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="click to snap" />

<TextView

    android:layout_height="100dp"

    android:id="@+id/test"
    android:layout_width="344dp"
    android:layout_height="101dp"
    android:text="test" />

Test button is not shown as remaining items in the view are taking up the whole screen. You should use ScrollView so that the screen becomes scrollable and handle varying screen sizes.

    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

  <LinearLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
  </LinearLayout>
</ScrollView>
