当导航栏和我的应用内容颜色相同时，我试图在导航栏和我的应用内容之间创建一个分隔线，就像谷歌通过他们最新的 Material Design 2.0 更新到他们的应用（如谷歌联系人和谷歌主页）所做的那样。我试着这样做：

getWindow().setNavigationBarDividerColor(Color.GRAY);

但是，我NoSuchMethodError在尝试时得到了一个。

我正在尝试找到一种方法来解决此问题或将分隔线放在导航栏上方的另一种方法。

这是堆栈：

setNavigationBarDividerColor()

  • 在导航栏和应用内容之间显示一条指定颜色的细线。

该setNavigationBarDividerColor()方法是在 API 级别 28 中添加的，因此它仅适用于 API 级别 28 及更高级别

您不能使用setNavigationBarDividerColor()低于 API 级别 28 的方法

使用时，setNavigationBarDividerColor()您将在屏幕截图下方收到警告检查

在此处输入图像描述

示例代码

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
     getWindow().setNavigationBarDividerColor(Color.GRAY)
  };
