<GridLayout    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="2"    android:alignmentMode="alignBounds"    android:rowCount="2"    android:columnCount="2"    android:columnOrderPreserved="false"    android:padding="@dimen/gap16"    android:orientation="horizontal">

    <android.support.v7.widget.CardView        android:layout_columnWeight="1"        android:layout_rowWeight="1"        android:layout_gravity="fill"        android:layout_column="0"        android:layout_row="0"        android:layout_margin="@dimen/gap16"        app:cardCornerRadius="@dimen/gap3"        app:cardElevation="@dimen/gap3">

        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_gravity="fill"            android:orientation="vertical">

            <Button                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:text="button 1"                android:background="@color/colorOdoOrange"                android:textColor="@color/colorWhite" />
        </LinearLayout>
    </android.support.v7.widget.CardView>

    <android.support.v7.widget.CardView        android:layout_columnWeight="1"        android:layout_rowWeight="1"        android:layout_gravity="fill"        android:layout_column="1"        android:layout_row="1"        android:layout_margin="@dimen/gap16"        app:cardCornerRadius="@dimen/gap3"        app:cardElevation="@dimen/gap16">

        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_gravity="fill"            android:orientation="vertical">

            <Button                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:text="button 2"                android:background="@color/colorOdoOrange"                android:textColor="@color/colorWhite" />
        </LinearLayout>
    </android.support.v7.widget.CardView>

</GridLayout>

VS

<mn.odo.ordersystem.components.OdoGridView    android:id="@+id/lv_goods_images"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:layout_marginTop="@dimen/gap16"    android:layout_marginBottom="@dimen/gap16"    android:isScrollContainer="false"    android:columnWidth="0dp"    android:gravity="center"    android:numColumns="5"    android:stretchMode="columnWidth"    android:horizontalSpacing="@dimen/gap0"    android:verticalSpacing="@dimen/gap0" />


gridview item:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="vertical">

    <Button        android:id="@+id/item_image"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@color/colorBgSubTitleBlue"        android:text="button 0" />

</LinearLayout>
