Earlier I was having an issue where going to my main activity (ColorMatch.java) from my splash page activity caused the program to get indefinitely stuck on a black screen. I found this was due to the run() method called in my onCreate in my main activity. I've tried commenting out certain things to see if it works, but as long as run() is called in my onCreate it automatically goes to black screen, without even giving an error for me to troubleshoot with. What could be causing this issue?
My ClassMatch.java:
package com.example.ali.colormatch;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.os.Bundle;
import android.app.Activity;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import java.util.Random;
public class ColorMatch extends AppCompatActivity {
int answer; //1 = red, 2 = blue, 3 = green, 4 = yellow
TextView textView3, textView2;
int count = 0;
volatile boolean playing = true;
private long timeThisFrame;
private Button testButton;
long fps;
int score;
int correctAnswer;
boolean matchColor = true, matchText = false;
long startFrameTime;
boolean firstTime = true;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_color_match);
textView3 = (TextView) findViewById(R.id.textView3);
textView2 = (TextView) findViewById(R.id.textView2);
run();
}
public void run() {
while (playing) {
startFrameTime = System.currentTimeMillis();
if (firstTime){
generateNewWord();
firstTime = false;
}
if (answer == correctAnswer){
score++;
count++;
generateNewWord();}
//else {
// quit();
// }
if (count % 5 == 0){
if (matchColor) {
textView3.setText(getString(R.string.gameSetting2)); // might need to add context with this - check http://stackoverflow.com/questions/10698945/reference-string-resource-from-code
matchColor = true;
matchText = false;
}
else if (matchText){
textView3.setText(getString(R.string.gameSetting1));
matchText = true;
matchColor = false;
}
}
}
//draw();
timeThisFrame = System.currentTimeMillis() - startFrameTime;
if (timeThisFrame > 0) {
fps = 1000 / timeThisFrame;
}
}
public void generateNewWord(){
//randomly select between red, green, blue, yellow
Random rand = new Random();
int randomInt1 = rand.nextInt(4) + 1; // assigns randomInt a value between 1 - 4
int randomInt2 = rand.nextInt(4) + 1;
if (randomInt1 ==1){
textView3.setText(R.string.Red);
}
else if (randomInt1 ==2){
textView3.setText(R.string.Green);
}
else if (randomInt1 == 3){
textView3.setText(R.string.Blue);
}
else if (randomInt1 == 4){
textView3.setText(R.string.Yellow);
}
//randomly select hex codes between rgby
if (randomInt2 ==1){
textView3.setTextColor(0xffcc0000);
}
else if (randomInt2 ==2){
textView3.setTextColor(0xff669900);
}
else if (randomInt2 == 3){
textView3.setTextColor(0xff000080);
}
else if (randomInt2 == 4){
textView3.setTextColor(0xffffff00);
}
if (matchColor) {
correctAnswer = randomInt2;
}
else if(matchText){
correctAnswer = randomInt1;
}
}
public void quit(){
}
public void sendBlue(View view){
answer = 2;
}
public void sendRed(View view){
answer = 1;
}
public void sendYellow(View view){
answer = 4;
}
public void sendGreen(View view){
answer = 3;
}
}
The activity_color_match.xml file that it uses:

For completion's sake, though I think it's probably irrelevant, here's my MainActivity.java. It seems to be working as I would like:
package com.example.ali.colormatch;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_page);
}
public void onSplashPageClick(View view){
Intent intent = new Intent(MainActivity.this, ColorMatch.class);
startActivity(intent);
}
public void onQuitClick(View view){
finish();
}
}
I am using a Nexus 5 to launch my app and debug. Thank you.
