我想在汉堡按钮动画中添加后退按钮，当后退按下的应用程序将返回到启动页面。
现在我的应用程序中有汉堡包按钮。当在主窗口中按下（标有橙色矩形）时，材料导航打开，当应用程序导航到所选窗口时，选择Home（标记为红色矩形）再次有汉堡包（黄色矩形）按钮，我想更改它。

如果第三张图片中的活动是新的，您只需在新活动的onCreate（）方法中添加以下代码即可。它可能有帮助...
final ActionBar toolbar = getSupportActionBar();
if (toolbar != null) {
toolbar.setDisplayHomeAsUpEnabled(true);
}
如果它在同一个活动中，并且通过viewpager只是不同的片段，请使用Toolbar.setNavigationIcon（）来更改你的图标。
