十天冲刺-10

昨天对详细界面中日期和消费类型的修改进行了处理，用到了whellview,和一个下拉框来进行规定，使用户只能点击固定的形式不能随意更改

遇到的问题就是获取到的日期是一个整体的，需要对其进行划分，才能添加至数据库

今天对详细项目界面进行进一步的改进，实现信息的修改并更新至数据库中

 

 public void click(View view)
    {
        db = helper_person.getWritableDatabase();
        switch (view.getId())
        {
            case R.id.delete:
            {
                AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setIcon(android.R.drawable.ic_dialog_info);
                builder.setTitle("温馨提示");
                builder.setMessage("确定要继续吗");
                builder.setCancelable(true);


                builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Log.i("tag","------"+detailed_id+"-----");

                       int count = db.delete("student","id=?",new String[] {String.valueOf(detailed_id)});
                       if(count > 0)
                       {
