Thanks, I could make it with your helps. But now I'm found a new
problem. I try to modify my textview with .setText method, but I got
this error:
ERROR/AndroidRuntime(3745): android.content.res.Resources
$NotFoundException: String resource ID #0x1
ERROR/AndroidRuntime(3745): at
android.content.res.Resources.getText(Resources.java:222)
ERROR/AndroidRuntime(3745): at
android.widget.TextView.setText(TextView.java:3011)
My source:
public class sc extends Activity{
ImageView secret;
public int counter;
public int counter_foe;
public TextView txt;
public TextView counter_txt;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.sc);
counter = 0;
counter_foe = 0;
txt = (TextView) findViewById(R.id.txt);
secret = (ImageView) findViewById(R.id.secret);
counter_txt = (TextView) findViewById(R.id.counter_me);
final TextView counter_txt_foe = (TextView)
findViewById(R.id.counter_me_foe);
Random rand = new Random();
int rndInt = rand.nextInt(3) + 1;
Runnable r1 = new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
int imageArr[] = new int[3];
imageArr[0] = R.drawable.r1_mirror;
imageArr[1] = R.drawable.s1_mirror;
imageArr[2] = R.drawable.p2_mirror;
Random rand = new Random();
int rndInt = rand.nextInt(3);
secret.setImageResource(imageArr[rndInt]);
if (rndInt == 0) {
counter_foe += 1;
Log.d("improve", "counter_foe
improved");
counter_txt_foe.setText(counter_foe);
}
}
};
secret.postDelayed(r1, 5000);
}
}
Thanks for any helps.
