Python&Appium实现安卓手机图形解锁详解编程语言

首先，在解锁状态下，建立一个Session，打开APP。然后，调用press_keycode()方法传入整型数值”26″，锁定屏幕。通过implicitly_wait()方法等待两秒后，再次调用press_keycode()方法按下电源键，点亮屏幕。这时候看到的手机界面如下所示：

此时，我们需要调用login_unlock()方法绘制图案解锁手机（预先设置好的解锁图形如上图所示）。

login_unlock()方法的详细介绍如下：

1、通过find_element_by_id()方法找到九宫格的View。

lock_pattern = self.driver.find_element_by_id("com.android.keyguard:id/lockPatternView")

2、通过lock_pattern变量获取View的初始坐标值和宽度高度。

x = lock_pattern.location.get('x') 
y = lock_pattern.location.get('y') 
width = lock_pattern.size.get('width') 
height = lock_pattern.size.get('height')

3、通过宽度计算偏移量。

offset = width / 6

4、通过偏移量计算九宫格内九个点各自的x,y坐标值。

p11 = int(x + width / 6), int(y + height / 6) 
p12 = int(x + width / 2), int(y + height / 6) 
p13 = int(x + width - offset), int(y + height / 6) 
p21 = int(x + width / 6), int(y + height / 2) 
p22 = int(x + width / 2), int(y + height / 2) 
p23 = int(x + width - offset), int(y + height / 2) 
p31 = int(x + width / 6), int(y + height - offset) 
p32 = int(x + width / 2), int(y + height - offset) 
p33 = int(x + width - offset), int(y + height - offset)

5、计算从当前点移动到下一个点的偏移量。

p3 = p13[0] - p11[0]

6、执行移动操作。

TouchAction(self.driver).press(x=p11[0], y=p11[1]).move_to(x=p3, y=0).wait(1000).move_to(x=0, y=p3).wait(1000).release().perform()

完整代码如下：

        width = lock_pattern.size.get('width') 
        height = lock_pattern.size.get('height') 
        # 偏移量 
        offset = width / 6 
        # 计算九宫格内九个点的x,y坐标值 
        p11 = int(x + width / 6), int(y + height / 6) 
        p12 = int(x + width / 2), int(y + height / 6) 
        p13 = int(x + width - offset), int(y + height / 6) 
        p21 = int(x + width / 6), int(y + height / 2) 
        p22 = int(x + width / 2), int(y + height / 2) 
        p23 = int(x + width - offset), int(y + height / 2) 
        p31 = int(x + width / 6), int(y + height - offset) 
        p32 = int(x + width / 2), int(y + height - offset) 
        p33 = int(x + width - offset), int(y + height - offset) 
        # 计算移动到下一个点的偏移量 
        p3 = p13[0] - p11[0] 
        sleep(3) 
        # 执行移动操作 
        TouchAction(self.driver).press(x=p11[0], y=p11[1]).move_to(x=p3, y=0).wait(1000).move_to(x=0, y=p3).wait( 
            1000).release().perform()
