如何在Android(NavigationDrawer)中更改汉堡包图标

问题描述：

在编写此线程之前，我已经尝试实现在stackoverflow中发现的不同解决方案，但是没有任何正常工作.

Before write this thread I have try to implement the different solution that I found in stackoverflow, but nothing work properly.

我正在开发使用自定义导航抽屉的Android应用，我必须更改操作栏的标准图标(现在是工具栏，对吗?)和设置图标.

I'm developing an Android applucation that use the custom navigation drawer, I have to change the standard icon of actionbar (now is toolbar, right ?), and settings icon.

这是我的代码:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setTitleTextColor(Color.parseColor("#009754"));
        setSupportActionBar(toolbar);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
    }

这就是我试图实现的目标:

And this is what i try to implement:

此解决方案不起作用:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitleTextColor(Color.parseColor("#009754"));
toolbar.setNavigationIcon(R.drawable.ic_draw);
setSupportActionBar(toolbar);

此解决方案不起作用:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.ic_custom_drawer_icon);

我不明白为什么我不能更改图标，我不知道出了什么问题...

I don't understand why i can't change the icon, i have no idea what's the problem...

答

简单而优雅的解决方案

放置

getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.dashboardicon);//your icon here

之后

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer,toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

导航活动中的总体解决方案

Overall Solution in Navigation Activity

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer,toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeAsUpIndicator(R.drawable.dashboardicon);

    navigationView= (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

注意:它不需要任何setNavigationOnClickListener()

Note: It doesnt need any setNavigationOnClickListener()
