Layout weight in Gridview

Question

I want the cards to fill the entire screen when it comes to various screen dimensions. I would like to use the weights or any other option that can do the same.

        <!--Card 1-->
        <android.support.v7.widget.CardView
            android:id="@+id/cardView1"
            android:layout_height="200sp"
            android:layout_width="150sp">

        </android.support.v7.widget.CardView>

        <!--Card 2-->
        <android.support.v7.widget.CardView
            android:id="@+id/cardView2"
            android:layout_height="200sp"
            android:layout_width="150sp">

        </android.support.v7.widget.CardView>

        <!--Card 3-->
        <android.support.v7.widget.CardView
            android:id="@+id/cardView3"
            android:layout_height="200sp"
            android:layout_width="150sp">

        </android.support.v7.widget.CardView>

        <!--Card 4-->
        <android.support.v7.widget.CardView
            android:id="@+id/cardView4"
            android:layout_height="200sp"
            android:layout_width="150sp">

        </android.support.v7.widget.CardView>
    </GridLayout>

For this you have to set the height of the gridview dynamically. In your Activity class define.

     public static int heighth;
     public static int width;
     DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metrics);

        widthh = metrics.widthPixels;
        heighth = metrics.heightPixels;

And after this in your gridview adapter class write

gridView.setMinimumHeight((Home.heighth)/3-70);

Here Home is your Activity class Home.java. I have divided by 3 because I have only 3 rows and the subtraction of 70 is just for adjusting the view. Hope it helps!

This doesn't work for devices with on screen menu buttons like Galaxy S9 and so on. The display size would return the whole size of the screen. — juanlugm, Jun 14 '19 at 06:26

try this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="2">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:weightSum="2">

    <android.support.v7.widget.CardView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1" />

    <android.support.v7.widget.CardView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1" />

</LinearLayout>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:weightSum="2">

    <android.support.v7.widget.CardView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1" />

    <android.support.v7.widget.CardView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1" />

</LinearLayout>

this might cause some performance problems on very old devices, but should not be a problem on the newer ones. Also, just add some margin around the cards to show the shadow if you want hope this helped.
