Use layout gravity instead of gravity  layout gravity tells the parent where it should be positioned  and gravity tells its child where they should be positioned    lt LinearLayout     android id    id groupNumbers      android orientation  horizontal      android layout gravity  center vertical      android layout weight  0 7      android layout width  wrap content      android layout height  wrap content  gt

use android layout gravity instead of android gravity  android gravity sets the gravity of the content of the View its used on  android layout gravity sets the gravity of the View or Layout in its parent

Use android weightSum property to the parent LinearLayout and give value 3  Then in the children LinearLayout use android layout weight 2 and 1 respectively  Then in the First Chil LinearLayout use android layout gravity  center vertical   As shown in the following code   lt LinearLayout                     android layout width  match parent                      android layout height  wrap content                      android weightSum  3                      android orientation  horizontal  gt                        lt LinearLayout                         android layout width  wrap content                          android layout height  wrap content                          android layout weight  2                          android layout gravity  center vertical                          android orientation  horizontal  gt                           lt TextView                             android id    id status text                              android layout width  wrap content                              android layout height  wrap content                              android text  00                              android textColor   color red                              android textSize   dimen default text size                                gt                             lt TextView                             android id    id status text                              android layout width  wrap content                              android layout height  wrap content                              android text  00                              android textColor   color red                              android textSize   dimen default text size                                gt                       lt  LinearLayout gt                       lt LinearLayout                         android layout width  wrap content                          android layout height  wrap content                          android layout weight  1  gt                           lt Button                           android layout width  fill parent                            android layout height  wrap content                            android text  Delete   gt                       lt  LinearLayout gt                   lt  LinearLayout gt
