this solution linear layouts told me need make using relative layout because using many linear layouts causes slow rendering, did not succed relative layouts.

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"

one way doing create item_layout.xml , add below:

 <?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/activity_main"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:gravity="center">     <button         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_toleftof="@+id/centerbutton"         android:text="mistery"/>     <button         android:id="@+id/centerbutton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerhorizontal="true"         android:text="romance"/>     <button         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_torightof="@+id/centerbutton"         android:text="science fiction"/> </relativelayout>

then everytime u add u can use row item layout. hope helps

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -
