廢話不多說直接上代碼

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//5.0 全透明實(shí)現(xiàn)
                Window window = getWindow();
                window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
                window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
                window.setStatusBarColor(Color.TRANSPARENT);

                WindowManager.LayoutParams lp = getWindow().getAttributes();
                lp.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
                getWindow().setAttributes(lp);

            } else {//4.4 全透明狀態(tài)欄
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            }

LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES是允許在劉海區(qū)域布局

還有其他兩種
