This is android studio. I have these five buttons: activity_main.xml < android.support.constraint.ConstraintLayout xmlns: android = http://schemas.android.com/apk/res/android xmlns: app = http://schemas.android.com/apk/res-auto xmlns: tools = http://schemas.android.com/tools android

This is android studio. I have these five buttons:

activity_main.xml

Here is a class I call GameEmulator:

import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class GameEmulator extends Activity{ public TextView textview; public TextView textview2; public TextView nameOne; public TextView nameTwo; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.layout); textview = findViewById(R.id.textView); textview2 = findViewById(R.id.textView2); nameOne = findViewById(R.id.name1); nameTwo = findViewById(R.id.name2); } }

with this layout:

layout.xml

How do I get the buttons to open up a new activity. I need the button gamestart to open the layout view connected to GameEmulator which is layout.xml. I keep getting errors so I need to see a way to make this work.
