第二次冲刺（三）

今天我完成了管理员界面的查看房间预定情况的部分。

关键代码为：

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_roominfo);
        Time time = new Time();
        time.setToNow();  //获取系统当前时间
        int year =time.year;
        int month=time.month+1;
        int day = time.monthDay;
        int hour = time.hour;
        int min = time.minute;
        int sec=time.minute;
        String y,mo,d,h,mi,s;
        y=String.valueOf(year);
        if(month<10)mo="0"+String.valueOf(month);
        else mo=String.valueOf(month);
        if(day<10)d="0"+String.valueOf(day);
        else d=String.valueOf(day);
        if(hour<10)h="0"+String.valueOf(hour);
        else h=String.valueOf(hour);
        if(min<10)mi="0"+String.valueOf(min);
        else mi=String.valueOf(min);
        if(sec<10)s="0"+String.valueOf(sec);
        else s=String.valueOf(sec);
        str=y+mo+d+h+mi+s;
        Bundle bundle=getIntent().getExtras();
        roomid=bundle.getInt("roomid");
        userid=bundle.getString("nowid");
        int id=roomid+1;
        Thread thread=new Thread(new Runnable() {
            @Override
            public void run() {
                MysqlUser mysqlUser=new MysqlUser();
                try {
                    String sql="select roomstate from roominfo where roomid='"+id+"'";
                    roomstate=mysqlUser.select(sql);
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        });
        thread.start();
        try {
            thread.join();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        Roominfo=(TextView) findViewById(R.id.roominfo);
        Roominfo.setText(names[roomid]);
        Roomstate=(TextView)findViewById(R.id.roomstate);
        if(roomstate.equals("1")){
            Roomstate.setTextColor(Color.rgb(255, 0, 0));
            Roomstate.setText("已被预定");
        }
        else {
            Roomstate.setTextColor(Color.rgb(0, 255, 0));
            Roomstate.setText("未被预定");
        }
        Roominfo.setTypeface(Typeface.createFromAsset(RoominfoActivity.this.getAssets(), "font/KaiTi.TTF"));
        Roomstate.setTypeface(Typeface.createFromAsset(RoominfoActivity.this.getAssets(), "font/KaiTi.TTF"));
        Roomimg=(ImageView)findViewById(R.id.roomimg);
        Roomimg.setImageResource(img[roomid]);
        Reserve=(Button)findViewById(R.id.reserve);
        Reserve.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int id=roomid+1;
                if(roomstate.equals("1"))
                Toast.makeText(RoominfoActivity.this, "房间已被预定",Toast.LENGTH_SHORT).show();
                else{
                    Toast.makeText(RoominfoActivity.this, "预定成功!",Toast.LENGTH_SHORT).show();
                    new Thread(new Runnable() {
                        @Override
                        public void run() {
                            MysqlUser mysqlUser=new MysqlUser();
                            try {
                                String sql="update roominfo set roomstate= 1,roomuserid='"+userid+"',reservetime='"+str+"'where roomid='"+id+"'";
                                mysqlUser.update(sql);
                            } catch (SQLException e) {
                                e.printStackTrace();
                            }
                        }
                    }).start();
                }
            }
        });
    }
