Use the layout weight attribute  The layout will roughly look like this    lt LinearLayout android orientation  horizontal      android layout height  fill parent       android layout width  fill parent  gt        lt LinearLayout          android layout weight  1           android layout height  fill parent           android layout width  0dp   gt        lt LinearLayout          android layout weight  1           android layout height  fill parent           android layout width  0dp   gt    lt  LinearLayout gt

In order to split the ui into two equal parts you can use weightSum of 2 in the parent LinearLayout and assign layout weight of 1 to each as shown below   lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout     xmlns android  http   schemas android com apk res android      android layout width  match parent      android layout height  match parent      android orientation  horizontal      android weightSum  2  gt            lt LinearLayout             android layout width  0dp              android layout height  match parent              android layout weight  1              android orientation  vertical  gt            lt  LinearLayout gt           lt LinearLayout             android layout width  0dp              android layout height  match parent              android layout weight  1              android orientation  vertical  gt           lt  LinearLayout gt     lt  LinearLayout gt

I am answering this question after 4-5 years but best practices to do this as below   lt RelativeLayout 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     tools context   MainActivity  gt       lt LinearLayout       android id    id firstLayout        android layout width  match parent        android layout height  match parent        android layout toLeftOf    id secondView        android orientation  vertical  gt  lt  LinearLayout gt       lt View       android id    id secondView        android layout width  0dp        android layout height  match parent        android layout centerHorizontal  true    gt       lt LinearLayout       android id    id thirdLayout        android layout width  match parent        android layout height  match parent        android layout toRightOf    id secondView        android orientation  vertical  gt  lt  LinearLayout gt   lt  RelativeLayout gt    This is right approach as use of layout weight is always heavy for UI operations  Splitting Layout equally using LinearLayout is not good practice
