There are about 290 items. opens a new page is clicked. but the “switch” or “if” after the error is over 250. What could be the reason?

if (position == 0) {
    Intent newActivity = new Intent(this, otobus5.class);
    startActivity(newActivity);
} else if (position == 1) {
    Intent newActivity6 = new Intent(this, otobus6.class);
    startActivity(newActivity6);
}

if (position == 290) {
    Intent newActivity = new Intent(this, otobus290.class);
    startActivity(newActivity);
} else if (position == 291) {
    Intent newActivity6 = new Intent(this, otobus291.class);
    startActivity(newActivity6);
}

Answer 1

What do these classes contain, and how do they vary? Most likely, you can have a single activity (otobus, in this case), and simply pass the position as an extra, like so:

Intent newActivity = new Intent(this, otobus.class);
newActivity.putIntExtra("position", position);
startActivity(newActivity);

Then, in the onCreate() of your otobus Activity, simply handle the layout of the activity based on the position passed:

Intent passedIntent = getIntent();
int selectedPosition = passedIntent.getExtra("position", -1);
