android 自定义类似91游，360应用内悬浮球（不使用系统悬浮框）

来源：互联网发布：java basicstroke 编辑：程序博客网时间：2024/04/27 22:54

项目需要，制作类似360，UC类似游戏内的悬浮球

1.开始使用的是系统的悬浮，添加系统权限android.permission.SYSTEM_ALERT_WINDOW，获取windowManager , 设置布局参数，添加view来实现，

优点：处于系统最上层，一次添加，多个地方使用，简单快捷，应用退出到后台还可以显示在界面上

缺点：不能保证所有手机都系统悬浮球弹出

之前用过采用版本API>18windowManagerParams.type = LayoutParams.TYPE_TOAST（系统不检查权限）反之采用windowManagerParams.type = LayoutParams.TYPE_PHONE

还是没有很好的保证系统悬浮球弹出，只能说android手机厂商太多，各家都有自己系统定制难兼容！

2.自定义应用内，悬浮球

思路：

为了完全弹窗悬浮球，只能定义悬浮球来实现了，之后每个窗体添加下，（写个基类包含添加该悬浮球功能，其他子类继承添加就好）

优点：保证所有机器都能弹出悬浮球

缺点：在需要添加的每个窗体，中添加，删除，对改悬浮球，应用退到后台后不可显示在前端

下面是自定义悬浮球控件，包括区域检测点击，onDraw有点乱，没整理抱歉，看官将就下哈！
