AlertDialog样式

Question

AlertDialog.Builder builder_delete=new AlertDialog.Builder(AskList.this,android.R.style.Theme_Holo_Light_Dialog);
builder_delete.setTitle("删除");
builder_delete.setMessage("确实要删除吗？");
builder_delete.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
        Thread thread=new Thread(new Runnable() {
            @Override
            public void run() {
                DBUntil.deleteAsk(mList.get(clickPostion).ID);
                handler.post(runAskDelete);
            }
        });
        thread.start();
    }
});
builder_delete.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {    }
});
builder_delete.create().show();为什么标题“删除”在横线下面，怎么能在横线上面呢？

可能是Theme主题的问题,你用this试试,AlertDialog.Builder dialog = new AlertDialog.Builder(this);
