리스트뷰 자동 클릭 조언 부탁드립니다.

Question

리스트뷰가 출력되고 1번째 리스트를 손으로 터치하지않고 자동으로 터치가되서

1번째 리스트를 터치했을 때 동작을 실행할 수 있는 방법이 있을까요?

android 에서는 코드로 클릭하는 메소드에 prefix 로 perform 을 사용 합니다. 

new Handler().post(new Runnable() {
    @Override
    public void run() {
        mList.performItemClick(
                mList.getChildAt(mActivePosition),
                mActivePosition,
                mList.getAdapter().getItemId(mActivePosition));
    }
});

답변 정말 감사드립니다.. 죄송하지만 하나만 더 여쭐게요..
리스트뷰 첫번째 줄에 있는 리스트를 클릭하려면
new Handler().post(new Runnable() {
    @Override
    public void run() {
        mList.performItemClick(
                mList.getChildAt(0),
                0,
                mList.getAdapter().getItemId(0));
    }
});
아닌가요? 계속 mList.getAdapter().getItemId(0));여기서 에러나는것 같습니다.

무슨 에런지 없네요?            .

java.lang.NullPointerException
어뎁터를 설정하기 전에 호출하신 모양인데요 ?
