android - GridLayout columns do not appear right -

i tried configure grid layout 2 rows , 2 columns. each element here occupies entire width of screen, while second column outside screen. please suggest doing wrong here.

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/colortheme"     android:orientation="vertical">      <gridlayout         android:id="@+id/moodsgridlayout"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_below="@+id/textview2"         android:columncount="2"         android:orientation="vertical"         android:rowcount="2">          <imagebutton             android:id="@+id/imagebutton"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_column="0"             android:layout_row="0"             app:srccompat="@mipmap/brewtv_logos" />          <imagebutton             android:id="@+id/imagebutton2"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_column="1"             android:layout_row="0"             app:srccompat="@mipmap/brewtv_logos" />          <imagebutton             android:id="@+id/imagebutton3"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_column="0"             android:layout_row="1"             app:srccompat="@mipmap/brewtv_logos" />          <imagebutton             android:id="@+id/imagebutton4"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_column="1"             android:layout_row="1"             app:srccompat="@mipmap/brewtv_logos" />     </gridlayout>  </linearlayout> 

try this:

for uniform width column , row in gridlayout use:

android:layout_columnweight="1"     android:layout_rowweight="1" 

use layout:

 <?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/color_white"     android:orientation="vertical">      <gridlayout         android:id="@+id/moodsgridlayout"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_below="@+id/textview2"         android:columncount="2"         android:orientation="vertical"         android:rowcount="2">          <imagebutton             android:id="@+id/imagebutton"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_column="0"             android:layout_columnweight="1"             android:layout_row="0"             android:layout_rowweight="1"             android:src="@mipmap/ic_launcher" />          <imagebutton             android:id="@+id/imagebutton2"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_column="1"             android:layout_columnweight="1"             android:layout_row="0"             android:layout_rowweight="1"             android:src="@mipmap/ic_launcher" />          <imagebutton             android:id="@+id/imagebutton3"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_column="0"             android:layout_columnweight="1"             android:layout_row="1"             android:layout_rowweight="1"             android:src="@mipmap/ic_launcher" />          <imagebutton             android:id="@+id/imagebutton4"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_column="1"             android:layout_columnweight="1"             android:layout_row="1"             android:layout_rowweight="1"             android:src="@mipmap/ic_launcher" />     </gridlayout>  </linearlayout> 

output:
