[android] 手机卫士自定义吐司

继续在之前监听来电的服务AddressService里，添加成员方法MyToast()

获取TextView对象，new出来，构造参数：上下文对象

调用TextView对象的setText()方法，设置文本

调用TextView对象的setTextSize()方法，设置大小，参数：int

调用TextView对象的setTextColor()方法，设置颜色

获取WindowManager对象，调用getSystemService()方法，参数：WINDOW_SERVICE

调用WindowManager对象的addView()方法，添加进视图，参数：View对象，WindowManager.LayoutParams对象

LayoutParams对象的设置参考Toast类的show()方法

此时，打电话和接电话会显示出来这个View，但是消不掉了

在之前判断来电的方法里，进行监听电话空闲状态，去除这个View

switch判断中添加TelephonyManager.CALL_STATE_IDLE

判空一下，判断TextView对象不为空

调用WindowManager对象的 removeView()方法，参数：View对象（上面添加的TextView）

使用布局文件

新建一个布局文件address_toast.xml

线性布局，横向排列，一个ImageView，一个TextVIew，TextView定义id

在自定义吐司的方法中

调用View.inflate()方法，获取View对象，参数：上下文，资源文件，null

添加这个View就可以了
