use tablelayout instead :

    <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"         xmlns:tools="http://schemas.android.com/tools"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical" >              <tablelayout                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:paddingtop="10dp"                 android:shrinkcolumns="1"                 android:stretchcolumns="1" >                  <tablerow                     android:descendantfocusability="beforedescendants"                     android:focusable="true"                     android:focusableintouchmode="true" >                      <textview                         android:layout_width="wrap_content"                         android:layout_height="wrap_content"                         android:text="name  :" />                      <edittext                         android:id="@+id/companyidedittext_id"                         android:layout_width="wrap_content"                         android:layout_height="wrap_content"                         android:text=""                          android:enabled="false"/>                 </tablerow>                  <tablerow                     android:descendantfocusability="beforedescendants"                     android:focusable="true"                     android:focusableintouchmode="true" >                      <textview                         android:layout_width="wrap_content"                         android:layout_height="wrap_content"                         android:text="rollnumber  :" />                      <edittext                         android:id="@+id/companynameedittext_id"                         android:layout_width="wrap_content"                         android:layout_height="wrap_content"                         android:text="" />                 </tablerow>     </tablelayout>  <button                  android:layout_height="wrap_content"                 android:layout_width="wrap_content"                 android:text="clickme"/>     </linearlayout>
