以下是我的要求
我的导航抽屉应该从右侧打开。我已经实现了这一点，我的导航抽屉从右到左打开。但问题是切换图标始终在左侧。如何将切换图标设置为右侧？
我已检查了以下 SO 问题，但它们都没有帮助：
以下是我尝试过的内容:

Toolbar的普通子项，因此如果您添加其他子View或需要下拉菜单，则需要小心处理，您可能需要手动实现以保持对齐正确。提前告知一下。干杯！ - Mike M.EndDrawerToggle中删除所有的arrowDrawable代码，并在toggleButton上设置任何你想要的图像。 - Mike M.Toolbar中有一个菜单，那么它会自动固定在最后面，而EndDrawerToggle会放在它之后，朝向中心。如果这是你的问题，你可以看看我的回答（链接）。 - Mike M.
