如何在 Android (NavigationDrawer) 中更改漢堡包圖標

[英]How to change hamburger icon in Android (NavigationDrawer)

在寫這個線程之前,我已經嘗試實現我在 stackoverflow 中找到的不同解決方案,但沒有任何工作正常。

我正在開發一個使用自定義導航抽屜的 Android applucation,我必須更改操作欄的標准圖標(現在是工具欄,對嗎?)和設置圖標。

這是我的代碼:

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);
    }

這就是我嘗試實施的:

此解決方案不起作用:

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

此解決方案不起作用:

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

我不明白為什么我不能更改圖標,我不知道有什么問題...

簡單而優雅的解決方案

地方

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

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();

導航活動整體解決方案

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()

禁用ActionBarDrawerToggle抽屜指示器:

toggle.setDrawerIndicatorEnabled(false);

進而:

toolbar.setNavigationIcon(R.drawable. ic_custom_drawer_icon);
Just use this :

toolbar.post(new Runnable() {
            @Override
            public void run() {
                Drawable d = ResourcesCompat.getDrawable(getResources(), R.mipmap.ic_launcher, null);
                toolbar.setNavigationIcon(d);
            }
        });
