GridView is a ViewGroup that displays items in a two-dimensional, scrollable grid. The grid items are automatically inserted to the layout using a ListAdapter..
we can dynamically insert views using an adapter and we can do build Layouts with an Adapter.
Here is a working example using a grid view example below
we just use a GridLayoutManager instead of a LinearLayoutManager when we need to set the RecyclerView.
MainActivity[MainActivity.class]
package com.androidfeeders.gridviewexample;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.GridView;
public class MainActivity extends AppCompatActivity {
GridView gridView;
ArrayAdapter arrayAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gridView=(GridView)findViewById(R.id.grid_view);
arrayAdapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,getResources().getStringArray(R.array.list));
gridView.setAdapter(arrayAdapter);
}
}
Layout Resource[activity_main.xml]
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
