需要完成的主要工作有：

1）劃分顯示位置

2）繪制狀態(tài)欄背景

3）繪制電池圖標(biāo)：一共7種圖標(biāo)baticos[7]

4）繪制時(shí)間：只顯示時(shí)和分

5）循環(huán)檢測(cè)時(shí)間變化，并更改顯示時(shí)間數(shù)值,同步判斷電池電量，繪制相應(yīng)圖標(biāo)

//1）繪制狀態(tài)欄背景320x12 x=0，y=0，w=320，h=22

LCD_Fill(0,0,320,22,BLACK);

//2)繪制電池電量 24X14右邊顯示，x=320-5-24，y=2，w=24，h=14

bat_status = 6;

minibmp_decode((u8*)baticos[bat_status],320-5-24,4,24,14,0,0);

//3）繪制時(shí)間30x16 x=320-5-24-10-40 y=3，w=40，h=16

POINT_COLOR = WHITE;

tmer_min = calendar.min;

LCD_ShowNum(320-5-24-10-40+24,3,calendar.min,2,16); }

}

//由其他界面函數(shù)中的while(1)里面調(diào)用，例如主函數(shù)中

void statusbar_change(void)

{

if(tmer_min!=calendar.min)

{

//1）繪制時(shí)間

LCD_ShowNum(320-5-24-10-40+24,3,calendar.min,2,16);

//2)繪制電池電量//目前沒(méi)有添加電池，只是循環(huán)改變而已，如果之后添加電池，根據(jù)獲得的電池量，修改bat_status的值

if(bat_status == 0||bat_status>6)

bat_status =6;

else

bat_status--;

minibmp_decode((u8*)baticos[bat_status],320-5-24,4,24,14,0,0);

}

}

在頭文件中添加，以便其他源文件中的函數(shù)調(diào)用

//add by joqian for statusbar

extern u8 bat_status;

extern u8 tmer_min;

extern void statusbar_change(void);
