我们如何更改ActionBarDrawerToggle图标？

Question

我是Android的新用户，在我的应用中，我正在使用DrawerLayout，这是 好的很好。但我想更改ActionBarDrawerToggle图标。

我们如何改变它？

我尝试了很多，但我无法达到预期的效果，请帮帮我一个人吗？

的xml： -

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/navigation_drawer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:local="http://schemas.android.com/apk/res-auto"
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/colorPrimary"
            local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            local:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    </LinearLayout>

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />

</android.support.v4.widget.DrawerLayout>

活动： -

public class MainActivity extends AppCompatActivity {
    ActionBarDrawerToggle actionBarDrawerToggle;
    DrawerLayout drawerLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_layout);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        drawerLayout = (DrawerLayout) findViewById(R.id.navigation_drawer);
        setSupportActionBar(toolbar);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.app_name,R.string.app_name);
        drawerLayout.setDrawerListener(actionBarDrawerToggle);
    }

Answer 1

将此行添加到工具栏

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    NavigationView navigationView = (NavigationView) findViewById(R.id.navigationView);
ActionBarDrawerToggle mToogle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.app_name, R.string.app_name);
    drawerLayout.addDrawerListener(mToogle);
    mToogle.syncState();
toolbar.setNavigationIcon(R.drawable.ic_your_image);

mToogle.syncState（）将处理操作（打开和关闭导航抽屉）。

Answer 2

你必须完成3个步骤：

1. 添加actionBarDrawerToggle.setDrawerIndicatorEnabled(false);
2. 添加toolbar.setNavigationIcon(R.drawable.menu_icon);

3. 将OnClick添加到新图标，如下所示：

   toolbar.setNavigationOnClickListener（new View.OnClickListener（）{             @覆盖             public void onClick（查看v）{                 drawerLayout.openDrawer（Gravity.LEFT）;             }         }）;

可能是正确的:-P

public class MainActivity extends AppCompatActivity {
    ActionBarDrawerToggle actionBarDrawerToggle;
    DrawerLayout drawerLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_layout);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        drawerLayout = (DrawerLayout) findViewById(R.id.navigation_drawer);
        drawerLayout = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                drawerLayout ,         /* DrawerLayout object */
                R.drawable.drawer_icon,  /* nav drawer icon to replace 'Up' caret */
                "drawer_open",  /* "open drawer" description */
                "drawer_close"  /* "close drawer" description */
                )
        setSupportActionBar(toolbar);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.app_name,R.string.app_name);
        drawerLayout.setDrawerListener(actionBarDrawerToggle);
    }
