这上面的报错的行数不对，我查看了下smali文件，报错代码：

具体对应代码 static void translucentStatusBar(Activity activity) { Window window = activity.getWindow(); window.addFlags(67108864); ViewGroup mContentView = (ViewGroup)activity.findViewById(16908290); //此处mContentView可能为null,导致崩溃 View mContentChild = mContentView.getChildAt(0); removeFakeStatusBarViewIfExist(activity); removeMarginTopOfContentChild(mContentChild, getStatusBarHeight(activity)); if (mContentChild != null) { ViewCompat.setFitsSystemWindows(mContentChild, false); } }

ContentView 就是 window.findViewById(Window.ID_ANDROID_CONTENT) 一般不会为 null. 可以看下你的布局代码吗? 是在 setContentView 之后调用的?

在4.4的安卓机型上使用getWindow().setContentView(自己的view) 设置布局，此translucentStatusBar 库会报上诉错误，改成setContentView(自己的view) 后正常。
