onResume and onCreate

It's me again with another question. My app loads on the emulator but does not do what I ask it to do. I have put the code in the onResume method, where it is supposed to loop 3 times with 15 second breaks in between. It doesn't do this. Are there any methods that can do this? To elaborate, I need a method which opens the app, displays some textviews and colors it in, waits 15 seconds, displays some more textviews and colors them in, waits 15 seconds, and displays the textviews and colors them in. Here is my code:

Java

package com.example.ani.opener;

import android.content.Intent;
import android.graphics.Color;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

import java.util.Random;
import java.util.concurrent.TimeUnit;


public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

protected void onResume(){
    super.onResume();
    LinearLayout toplayout = (LinearLayout) findViewById(R.id.toplayout);
    int loopthing = 1;
    while(loopthing < 4){
        int childnum = 0;
        LinearLayout row1 = (LinearLayout) toplayout.getChildAt(0);
        LinearLayout row2 = (LinearLayout) toplayout.getChildAt(1);
        LinearLayout row3 = (LinearLayout) toplayout.getChildAt(2);
        while(childnum <=4){
            TextView spot1 = (TextView) row1.getChildAt(childnum);
            spot1.setBackgroundColor(Color.WHITE);
            childnum += 1;
        }
        int childnum2 = 0;
        while(childnum2 <=4){
            TextView spot2 = (TextView) row1.getChildAt(childnum2);
            spot2.setBackgroundColor(Color.WHITE);
            childnum2 += 1;
        }
        int childnum3 = 0;
        while(childnum3 <=4){
            TextView spot3 = (TextView) row1.getChildAt(childnum3);
            spot3.setBackgroundColor(Color.WHITE);
            childnum3 += 1;
        }
        int looper = 1;
        Random initloop = new Random();
        int looptime = initloop.nextInt(10-1) + 1;
        while(looper <= looptime){
            Random findnum = new Random();
            int i = findnum.nextInt(2-0) + 0;
            LinearLayout layout = (LinearLayout) toplayout.getChildAt(i);
            Random spotinit = new Random();
            int a = spotinit.nextInt(4-0) + 0;
            TextView spot = (TextView) layout.getChildAt(a);
            spot.setBackgroundColor(Color.RED);
            looper += 1;
        }
        LinearLayout disabledrow = (LinearLayout) toplayout.getChildAt(0);
        TextView disabledspot1 = (TextView) disabledrow.getChildAt(0);
        TextView disabledspot2 = (TextView) disabledrow.getChildAt(1);
        disabledspot1.setBackgroundColor(Color.BLUE);
        disabledspot2.setBackgroundColor(Color.BLUE);
        loopthing +=1;
        try {
            TimeUnit.SECONDS.sleep(15);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}
