Try this using ConstraintLayout
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:orientation="vertical">
<ImageView
android:id="@+id/imgOne"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="@color/colorPrimary"
app:layout_constraintBottom_toTopOf="@+id/imgThree"
app:layout_constraintEnd_toStartOf="@id/imgTwo"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="NEW ITEM"
android:textColor="@color/colorBlack"
app:layout_constraintBottom_toBottomOf="@id/imgOne"
app:layout_constraintEnd_toStartOf="@id/imgTwo"
app:layout_constraintStart_toStartOf="parent" />
<ImageView
android:id="@+id/imgTwo"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="@color/colorblue"
app:layout_constraintBottom_toTopOf="@+id/imgFour"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toEndOf="@id/imgOne"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="NEW ITEM"
android:textColor="@color/colorBlack"
app:layout_constraintBottom_toBottomOf="@id/imgTwo"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="@id/imgTwo" />
<ImageView
android:id="@+id/imgThree"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="@color/colorGreen"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="@id/imgTwo"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/imgOne" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="NEW ITEM"
android:textColor="@color/colorBlack"
app:layout_constraintBottom_toBottomOf="@id/imgThree"
app:layout_constraintEnd_toStartOf="@id/imgFour"
app:layout_constraintStart_toStartOf="parent" />
<ImageView
android:id="@+id/imgFour"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="@color/colorAccent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toEndOf="@id/imgThree"
app:layout_constraintTop_toBottomOf="@+id/imgTwo" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="NEW ITEM"
android:textColor="@color/colorBlack"
app:layout_constraintBottom_toBottomOf="@id/imgThree"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="@id/imgTwo" />
</androidx.constraintlayout.widget.ConstraintLayout>

This is the easiest way to it.
LinearLayout :
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<androidx.appcompat.widget.AppCompatImageButton
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<androidx.appcompat.widget.AppCompatImageButton
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
</androidx.appcompat.widget.LinearLayoutCompat>
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<androidx.appcompat.widget.AppCompatImageButton
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<androidx.appcompat.widget.AppCompatImageButton
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
</androidx.appcompat.widget.LinearLayoutCompat>
</androidx.appcompat.widget.LinearLayoutCompat>
ConstraintLayout :
