I am new to android development and I am developing an app where the app downloads pictures from server and show them in a gridView. But some extra spaces are coming up when the app is run on a bigger screen phone. Here are some screenshots. How do I solve this ? I have the model of each item with a fixed height and width of 110dp

My image model : 

```
<?xml version="1.0" encoding="utf-8"?>
<ImageView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="110dp"
    android:layout_height="110dp"
    app:srcCompat="@drawable/post2"
    android:id="@+id/imageView2"
    android:adjustViewBounds="true"
    android:scaleType="centerCrop"
    android:layout_margin="1.5dp" />

```

My Recycler View : 

```
<android.support.v7.widget.RecyclerView
                android:id="@+id/gallerygrid"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_marginTop="4dp"
                android:numColumns="auto_fit"
                android:stretchMode="columnWidth"
                android:visibility="visible"
                android:layout_gravity="center">

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

```
