    public void busInformation(String[] info){
         busClickNumber = info[0].toString();
        busClickTime = info[1].toString();
        busClickRoute = info[2].toString();

        tv1Click.setText(busClickNumber);
        tv2Click.setText(busClickTime);
        tv3Click.setText(busClickRoute);   
    }
}

从您的评论/回答中，似乎其中一个findViewById正在返回null。当找不到视图时会发生这种情况。确保布局文件中的id与java代码中的id相同。
