How to dismiss an android pop up window using an okay button

Question

I'm making an app for a school project and I'm stuck on one area. I want to use an okay button to dismiss the pop up window. If you have any suggestions or if there is a better way to implement popups please share them.

package xyz.ashraf.whoisdelasalle;

import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;

public class Pop extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.popwindow);

    DisplayMetrics dm = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(dm);

    int width = dm.widthPixels;
    int height = dm.heightPixels;

    getWindow().setLayout((int)(width*.8),(int)(height*.5));

}
}

Java code^

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ScrollView01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
<RelativeLayout
    android:layout_width="match_parent" android:layout_height="match_parent"
    android:background="#FAFAFA">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="John Baptist de La Salle was a French priest, educational reformer, and founder of the Institute of the Brothers of the Christian Schools. He is a saint of the Roman Catholic Church and the patron saint of teachers."
    android:id="@+id/textView"
    android:background="#FAFAFA"
    android:textColor="#000000"
    android:layout_alignParentTop="true"
    android:layout_marginTop="15dp"
    android:layout_marginRight="15dp"
    android:layout_marginLeft="15dp"/>

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="OK"
    android:id="@+id/okButton_who"
    android:textColor="#00E676"
    android:background="#FAFAFA"
    android:layout_below="@+id/textView"
    android:layout_alignRight="@+id/textView"
    android:layout_alignEnd="@+id/textView"
    android:layout_marginTop="50dp"/>

</RelativeLayout>
    </ScrollView>

XML^

Thanks in advance!

Not sure if this would work, but you can try:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.popwindow);

    DisplayMetrics dm = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(dm);

    int width = dm.widthPixels;
    int height = dm.heightPixels;

    getWindow().setLayout((int)(width*.8),(int)(height*.5));

    Button okButton = (Button) findViewById(R.id.okButton_who);
    okButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            finish();
        }
    });

}

Or else you could use Dialogs or DialogFragments as akadouri suggested.
