工程里代码

public void onTouchingLetterChanged(String s) {
??// TODO Auto-generated method stub
??if (alphaIndexer(s) >= 0) {
???int position = alphaIndexer(s);
???personList.setSelection(position);
???overlay.setText(s);
???overlay.setVisibility(View.VISIBLE);
???handler.removeCallbacks(overlayThread);
???handler.postDelayed(overlayThread, 1500);
??}
?}

?if (alphaIndexer(s) >= 0) {
