RecyclerView item height and width change dynamically Android

Question

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>

Set height and width dynamically according to the screen size. this is the best way to get perfect result.

DisplayMetrics displaymetrics = new DisplayMetrics();         ((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);         //if you need three fix imageview in width         int devicewidth = displaymetrics.widthPixels / 3;          //if you need 4-5-6 anything fix imageview in height         int deviceheight = displaymetrics.heightPixels / 4;          holder.image_view.getLayoutParams().width = devicewidth;          //if you need same height as width you can set devicewidth in holder.image_view.getLayoutParams().height         holder.image_view.getLayoutParams().height = deviceheight; 

try this in adapter in getview hope you get better result in all device

EDIT: Or to set same height same as width you can set devicewidth in height also like below:

holder.image_view.getLayoutParams().height = devicewidth;
