利用python+tkinter作一個簡單的智能電視遙控器

要經過python實現遙控器功能分兩步：

第一步：開發圖形化界面

第二步：使PC端給電視發送相應指令

如今就開始第一步操做實現遙控器功能，python2輸入如下代碼

注意：python3須要將代碼中的from Tkinter import *

　　　　　　　　　　　替換爲from tkinter import *

　　　　　　　　　　　將from SimpleDialog import *

　　　　　　　　　　　替換爲import tkinter.simpledialog

#coding=utf-8
from Tkinter import *
from SimpleDialog import *

'''
from tkinter import *
import tkinter.simpledialog
'''
root = Tk()
#設置圖形的寬高
root.geometry('120x200')
#設置圖形爲不可拉昇
root.resizable(0, 0)
#設置圖形的標題
root.title('遙控器')
#添加組件佈局
Button(root,text="電源",command="").place(x=45,y=0,)
Button(root,text="左鍵",command="").place(x=0,y=60,height=30)
Button(root,text="右鍵",command="").place(x=90,y=60,height=30)
Button(root,text="上鍵",command="").place(x=45,y=30,height=30)
Button(root,text="下鍵",command="").place(x=45,y=90,height=30)
Button(root,text="OK",command="").place(x=40,y=60,height=30,width=45)
Button(root,text="主頁",command="").place(x=0,y=130,height=30,width=30)
Button(root,text="返回",command="").place(x=45,y=130,height=30,width=30)
Button(root,text="菜單",command="").place(x=90,y=130,height=30,width=30)
Button(root,text="音+",command="").place(x=0,y=170,height=30,width=30)
Button(root,text="音-",command="").place(x=45,y=170,height=30,width=30)
Button(root,text="BIU",command="").place(x=90,y=170,height=30,width=30)       
mainloop()

運行成功後，Python2界面顯示如左圖，Python3界面顯示如右圖

第二步，在command中加入相應的鍵值對應的方法，能夠先定義好各個方法，舉個例子，好比電視的肯定鍵對應的鍵值是23，那麼咱們先定義一個ok鍵對應的方法

def ok():
    subprocess.call('adb shell input keyevent 23', shell=True)

同時，考慮到按ok鍵還沒執行完畢，咱們又按了其它鍵，這樣就須要加入多線程，方法以下

def ok_1():
    subprocess.call('adb shell input keyevent 23', shell=True)
    
def ok():
    t=threading.Thread(target=ok_1)
    t.start()
    

這樣，簡單的遙控器功能，咱們就作完了：

#coding=utf-8
from Tkinter import *
from SimpleDialog import *
import subprocess
import threading
'''
from tkinter import *
import tkinter.simpledialog
'''

def up_1():
    subprocess.call('adb shell input keyevent 19', shell=True)
    
def up():
    t=threading.Thread(target=up_1)
    t.start()
    
def down_1():
    subprocess.call('adb shell input keyevent 20', shell=True)
    
def down():
    t=threading.Thread(target=down_1)
    t.start()

def left_1():
    subprocess.call('adb shell input keyevent 21', shell=True)
    
def left():
    t=threading.Thread(target=left_1)
    t.start()

def right_1():
    subprocess.call('adb shell input keyevent 22', shell=True)
    
def right():
    t=threading.Thread(target=right_1)
    t.start()

def home_1():
    subprocess.call('adb shell input keyevent 3', shell=True)    

def home():
    t=threading.Thread(target=home_1)
    t.start()

def back_1():
    subprocess.call('adb shell input keyevent 4', shell=True)
    
def back():
    t=threading.Thread(target=back_1)
    t.start()

def ok_1():
    subprocess.call('adb shell input keyevent 23', shell=True)
    
def ok():
    t=threading.Thread(target=ok_1)
    t.start()
    
def voice_1():
    subprocess.call('adb shell input keyevent 24', shell=True)

def voice1():
    t=threading.Thread(target=voice_1)
    t.start()

def voice_2():
    subprocess.call('adb shell input keyevent 25', shell=True)

def voice2():
    t=threading.Thread(target=voice_2)
    t.start()

def menu_1():
    subprocess.call('adb shell input keyevent 82', shell=True)

def menu():
    t=threading.Thread(target=menu_1)
    t.start()

def power_1():
    subprocess.call('adb shell input keyevent 754', shell=True)

def power():
    t=threading.Thread(target=power)
    t.start()

def biu_1():
    subprocess.call('adb shell input keyevent 733', shell=True)

def biu():
    t=threading.Thread(target=biu_1)
    t.start()


root = Tk()
#設置圖形的寬高
root.geometry('120x200')
#設置圖形爲不可拉昇
root.resizable(0, 0)
#設置圖形的標題

#添加組件佈局
Button(root,text="電源",command=power).place(x=45,y=0,)
Button(root,text="左鍵",command=left).place(x=0,y=60,height=30)
Button(root,text="右鍵",command=right).place(x=90,y=60,height=30)

如何使其能操控電視，須要咱們先使用adb命令鏈接電視ip，在cmd下，輸入格式爲：adb connect 192.168.XX.XXX

若鏈接成功後，輸入adb devices顯示 192.168.XX.XXX devices，表示鏈接成功，以後就能夠用電腦上的遙控器控制電視了
