android 自定義類似91遊，360應用內懸浮球（不使用系統懸浮框）
阿新 • • 發佈：2019-01-04
專案需要，製作類似360，UC類似遊戲內的懸浮球
1.開始使用的是系統的懸浮，新增系統許可權android.permission.SYSTEM_ALERT_WINDOW，獲取windowManager , 設定佈局引數，新增view來實現，
優點：處於系統最上層，一次新增，多個地方使用，簡單快捷，應用退出到後臺還可以顯示在介面上
缺點：不能保證所有手機都系統懸浮球彈出
之前用過採用版本API>18windowManagerParams.type = LayoutParams.TYPE_TOAST（系統不檢查許可權）反之採用windowManagerParams.type = LayoutParams.TYPE_PHONE
還是沒有很好的保證系統懸浮球彈出，只能說android手機廠商太多，各家都有自己系統定製難相容！
2.自定義應用內，懸浮球
思路：
為了完全彈窗懸浮球，只能定義懸浮球來實現了，之後每個窗體新增下，（寫個基類包含新增該懸浮球功能，其他子類繼承新增就好）
優點：保證所有機器都能彈出懸浮球缺點：在需要新增的每個窗體，中新增，刪除，對改懸浮球，應用退到後臺後不可顯示在前端
下面是自定義懸浮球控制元件，包括區域檢測點選，onDraw有點亂，沒整理抱歉，看官將就下哈！
