android白色背景狀態欄字體顏色

改變狀態欄顏色的彷彿只能用於小米，魅族，已經6.0以上的手機，vivo系統源碼不開發，所以沒辦法修改，直接上代碼

小編髮現一個小問題，就是對於華爲有下部虛擬導航欄的手機來說說，可能會江虛擬導航欄變成白色或者透明四，最好最後把BarTextColorUtils中的activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);注掉試試
或者大家也可收索一下全局，能不能搜索到FLAG_TRANSLUCENT_NAVIGATION這個字段，不要把底部設置爲透明就可以了，由於我身邊沒有手機，所以這僅僅作爲提示
