Create a new layout file Gridview_item.xml

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:gravity= "Center"android:orientation= "vertical" >    <ImageViewAndroid:id= "@+id/iv_icon"Android:background= "@drawable/ic_launcher"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content" />    <TextViewAndroid:id= "@+id/tv_title"Android:text= "Module title"android:textsize= "18SP"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content" /></LinearLayout>

The effect after operation is as follows:
