android - 使用带有导航组件的抽屉导航时如何更改操作栏图标(汉堡图标)

Question

我想更改主页指示器，但在使用导航组件时它不起作用
我从这里尝试了解决方案，但没有奏效
how to change toolbar icon (hamburger icon) when using navigation drawer with jetpack navigation component
我的代码

    setSupportActionBar(binding.toolbar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);

    AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(R.id.myTeamFragment,
            R.id.myTasksFragment, R.id.meetingsFragment, R.id.freeTimeFragment, R.id.dashboardFilterFragment)
            .setOpenableLayout(binding.getRoot())
            .build();
    NavigationUI.setupWithNavController(binding.toolbar, getNavController(), appBarConfiguration);

然后作为解决方案提到

ActionBar actionBar = getSupportActionBar();
    getNavController().addOnDestinationChangedListener((controller, destination, arguments) -> {
        if (destination.getId() == R.id.dest0
                || destination.getId() == R.id.dest1
                || destination.getId() == R.id.dest2
                || destination.getId() == R.id.dest3
                || destination.getId() == R.id.dest4){

            actionBar.setHomeAsUpIndicator(R.drawable.ic_hambergur_menu);
        } else {
            actionBar.setHomeAsUpIndicator(R.drawable.ic_hambergure_back);
        }
    });

Answer 1

您正在使用带有 Toolbar 的设置

NavigationUI.setupWithNavController(binding.toolbar, getNavController(), appBarConfiguration);

然后使用 Toolbar API 代替 ActionBar API:

    navController.addOnDestinationChangedListener { controller, destination, arguments ->
        if (destination.id == R.id.nav_home){
            toolbar.setNavigationIcon(R.drawable.xxxx)
        }
    }
