I created an android app that tests your reflects speed.
at first the app is still when you press(State 0) the app starts a thread that waits a couple of seconds before showing a green screen. When the green screen is shown(State 1) you have to press as fast as you can. if you press the green(state 2) you are shown the reflect time
the problem I'm having that when a person clicks too soon, i have to stop the thread which causes the app to crash(thread.stop()). Any suggestions?
public class MainActivity extends Activity implements OnClickListener{
TextView tvs,tvas;
RelativeLayout rl;
int state; //0=red 1=green 2=tapped-green
long end,start,result;
Thread th;
Boolean dont;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rl = (RelativeLayout) findViewById(R.id.rl);
tvs = (TextView) findViewById(R.id.tvs);
tvas = (TextView) findViewById(R.id.tvas);
dont=true;
state=0;
Typeface myTypeface = Typeface.createFromAsset(this.getAssets(),"RobotoCondensed-Bold.ttf");
tvs.setTypeface(myTypeface);
tvas.setTypeface(myTypeface);
rl.setOnClickListener(this);
tvs.setOnClickListener(this);
tvas.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (state) {
case 0:
tvs.setText("Any Min Now");
rl.setBackgroundColor(Color.rgb(255, 68, 68));
final Handler mHandler = new Handler();
state=1;
dont=true;
th = new Thread((new Runnable() {public void run() {while (true){try {Thread.sleep(randInt());mHandler.post(new Runnable() {public void run() {
if(dont){ //not helping
rl.setBackgroundColor(Color.GREEN);
start = SystemClock.uptimeMillis();
state=2;
}
}});} catch (Exception e) {}}}}));
th.start();
break;
case 1:
tvs.setText("Too Soon!");
tvas.setText("Tap AnyWhere To restart");
dont=false;
rl.setBackgroundColor(Color.rgb(255, 68, 68));
state=0;
break;
case 2:
end = SystemClock.uptimeMillis();
result=end-start;
tvs.setText("UR Reaction Time= "+result+"ms");
tvas.setText("Tap AnyWhere To restart");
state=0;
dont=false;
th.interrupt(); //giving me wrong numbers
break;
}
}
public static int randInt() { //creates a random number
Random rand = new Random();
int randomNum = rand.nextInt((6000 - 2000) + 1) + 2000;
return randomNum;
}
}
