Generate ID in android

Question

I've created checkboxes programmatically, and i need to set layout_above for each of them( so they will be above each other). this code works in loop, so it will generate few checkboxes, but i need to set id. how can I properly generate it?

CheckBox checkBox = new CheckBox(getApplicationContext());
     RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams
        (RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        layoutParams.addRule(RelativeLayout.ABOVE, checkBox.getId());
        checkBox.setLayoutParams(layoutParams);
        checkBox.setWidth(getScreenWidth());
        checkBox.setText(questions.get(questionId).answers.get(index));
    ll.addView(checkBox);

Not sure. I generate it in while loop, and it generates like 4-7 checkboxes. — Василий Богданец, May 12 '16 at 11:25

   int CHECK_BOX_ID = 1;
 CheckBox checkBox = new CheckBox(getApplicationContext());
 RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams
    (RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParams.addRule(RelativeLayout.ABOVE, checkBox.getId());
    checkBox.setLayoutParams(layoutParams);
    checkBox.setWidth(getScreenWidth());
    checkBox.setId(CHECK_BOX_ID);
    CHECK_BOX_ID++;
    checkBox.setText(questions.get(questionId).answers.get(index));
ll.addView(checkBox);

 checkBox.setId(checkBoxId);

generate a random number and increment it within the loop. This should probably do it.
