Fast text changing - Android Studio

Question

I have a random number generator android app and I want to add a "computer thinking process" to it.

I mean, I want to make the screen display fast changing random numbers for 5 seconds and then display the random number (after the "thought process").

I tried doing so, and it doesn't work:

for(int i = 0; i < 50; i++){
try{
textView.setText(String.valueOf(random.randInt(1000)));
Thread.sleep(100); // 0.1 sec
} catch(IntrupttedException e){ }
}

Answer 1

And… did that work?

Answer 2

When you animate something you could build in the calling of random.randint(1000) statement in the animation instead for loop and sleeping its thread.

Answer 3

Plesse use web searching. Here we do not learn android studio:

Answer 6

not sure if i get you right but try

private int i;
private Handler handler;
private Runnable runnable;
.
.
.

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

}

// this function starts draw
public void startDraw() {
handler.postDelayed(runnable, 0);
}

// this will initialize draw and after 50
// views of value ( after 5s) it will stop
public void randomInit() {
final Random r = new Random();
handler = new Handler();
i = 0;
runnable = new Runnable() {
public void run() {
textView.setText("" + r.nextInt(1000));
i++;
if(i == 50) handler.removeCallbacks(this);
else handler.postDelayed(this, 100);
}
};
}
