Auto adjust row height to fit screen in gridview

I've got a simple grid layout:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" xmlns:app="http://schemas.android.com/apk/res-auto" tools:context=".pkgFragment.InputDataOverviewFragment"> <com.google.android.material.appbar.AppBarLayout android:id="@+id/abToolBarLayout" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/BrightYellowCrayola"> <androidx.appcompat.widget.Toolbar android:id="@+id/tbMenuIconWithTitle" app:navigationIcon="@drawable/baseline_menu_24" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:title="@string/InputData" > </androidx.appcompat.widget.Toolbar> </com.google.android.material.appbar.AppBarLayout> <GridView android:id="@+id/inputDataGrid" android:layout_below="@id/abToolBarLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:numColumns="2" android:verticalSpacing="1dp" android:background="#e5e5e5" android:horizontalSpacing="2dp" /> </RelativeLayout> 

Layout for grid item:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <RelativeLayout android:id="@+id/inputDataGridValues" android:layout_height="wrap_content" android:layout_width="match_parent" android:background="#fff" > <TextView android:id="@+id/itemTitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" /> <ImageView android:id="@+id/itemImage" android:layout_width="90dp" android:layout_height="90dp" android:layout_centerHorizontal="true" android:layout_centerVertical="true" /> </RelativeLayout> </RelativeLayout> 

The issue I'm facing is that the height wont adjust to the full screen so that there is no empty space left due to my android:height="wrap_content" attribute:

In order to solve this problem I tried to set the height based on the screenheight/numberofrows I have:

@SuppressLint("SetTextI18n") @Override public View getView(int position, View convertView, ViewGroup parent) { InputDataType inputDataType = getItem(position); if (convertView == null) { convertView = LayoutInflater.from(getContext()).inflate(R.layout.grid_item, parent, false); } DisplayMetrics metrics = new DisplayMetrics(); ((MainActivity)getContext()).getWindowManager().getDefaultDisplay().getMetrics(metrics); convertView.setMinimumHeight(metrics.heightPixels/3); //I will have free rows ImageView icon = (ImageView) convertView.findViewById(R.id.itemImage); TextView text = (TextView) convertView.findViewById(R.id.itemTitle); //set icon and title bla bla bla } 

However the issue with this approach is that the height is now to big/there is a lot of emtpy spaces between each row:

How can I solve this issue?
