LinearLayout

•LinearLayout organizes elements along a single line. You specify whether that line is verticle or horizontal using android:orientation. Here is a sample Layout XML using LinearLayout.

Ex:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

  android:orientation="horizontal"

  android:layout_width="fill_parent"

    android:layout_height="fill_parent">

     <Button

      android:id="@+id/backbutton"

      android:text="Back"

      android:layout_width="wrap_content"

      android:layout_height="wrap_content" />

    <TextView

      android:text="First Name"

      android:layout_width="wrap_content"

      android:layout_height="wrap_content" />

    <EditText

      android:width="100px"

      android:layout_width="wrap_content"

      android:layout_height="wrap_content" />

<TextView

      android:text="Last Name"

      android:layout_width="wrap_content"

      android:layout_height="wrap_content" />

    <EditText

      android:width="100px"

      android:layout_width="wrap_content"

      android:layout_height="wrap_content" />

</LinearLayout>
