dBuilder.setMessage("提示");           //message是自定义的消息
dBuilder.setCancelable(false);
dBuilder.setPositiveButton("ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
// dBuilder.setNegativeButton("no", new DialogInterface.OnClickListener() {
//
// @Override
