嗨,我正在使用"android.support.v4.widget.DrawerLayout"抽屉.我想改变抽屉图标的颜色.请告诉我如何做到这一点.我分享我的代码.请看一下并建议我如何更改图标颜色更改.

 toolbar = (Toolbar) findViewById(R.id.tool_bar);
 setSupportActionBar(toolbar);
 getSupportActionBar().setDisplayHomeAsUpEnabled(true);
 toolbar.setNavigationIcon(R.drawable.drawer);
 toolbar.hideOverflowMenu();
 getSupportActionBar().setTitle(null);
 ImageView img = (ImageView) findViewById(R.id.imgCourses);   
 mRecyclerView = (RecyclerView) findViewById(R.id.RecyclerView);
 mRecyclerView.setHasFixedSize(true);
 Drawer = (DrawerLayout) findViewById(R.id.DrawerLayout);
 mAdapter = new MyAdapter(TITLES,NAME,EMAIL,PROFILE,this);  
 mRecyclerView.setAdapter(mAdapter); 
 mRecyclerView.setVerticalScrollBarEnabled(false);
 mLayoutManager = new LinearLayoutManager(this);
 mRecyclerView.setLayoutManager(mLayoutManager);  
 mDrawerToggle = new   ActionBarDrawerToggle(this,
                                             Drawer,
                                             toolbar,
                                             R.string.openDrawer,
                                             R.string.closeDrawer)
    {
        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
        }

        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);

        }

    };
    Drawer.setDrawerListener(mDrawerToggle);
    mDrawerToggle.syncState();
    Drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

这是我的mainlayout文件。

这是主布局文件，我在其中编写与导航抽屉相关的代码，还使用 ​​include 包含工具栏。

    <LinearLayout android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:android="http://schemas.android.com/apk/res/android">
        <android.support.v4.widget.DrawerLayout
            android:id="@+id/navigation_Drawerlayout"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            tools:openDrawer="start">
            <include layout="@layout/navigation_drawerlayout" />

            <android.support.design.widget.NavigationView
                android:id="@+id/navigation_View"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_gravity="start"
                android:fitsSystemWindows="true">

                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="vertical">

                    <include layout="@layout/navigation_headerview" />

                    <android.support.v7.widget.RecyclerView
                        android:id="@+id/navigationRecycleView"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"></android.support.v7.widget.RecyclerView>
                </LinearLayout>


            </android.support.design.widget.NavigationView>


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










    </LinearLayout>

navigation_toolbarlayout.xml 该布局定义了toolbar上面代码中使用的代码

    <?xml version="1.0" encoding="utf-8"?>

        android:layout_height="match_parent">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            <android.support.v7.widget.Toolbar

                android:layout_height="wrap_content"
                android:background="@color/colorPrimary"
                android:minHeight="?attr/actionBarSize"
                app:titleTextColor="@android:color/white">

                <!-- Screen title -->
                <TextView
                    android:id="@+id/toolbarTitle"
                    style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
                    android:layout_width="wrap_content"

            </android.support.v7.widget.Toolbar>

我通过在GitHub的一个简单测试项目中添加工具栏和右侧抽屉,扩展了着名的Google 导航抽屉示例:

如何在工具栏中添加"汉堡"按钮 - 这将打开正确的抽屉(目前只能用手指轻扫)？

左侧抽屉的"汉堡"按钮已经存在并运行良好(可能是由ActionBarDrawerToggle添加的？)

这是我当前的activity_main.xml:

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

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

        <android.support.v7.widget.Toolbar 
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </LinearLayout>

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice" />

    <ListView
        android:id="@+id/right_drawer"
        android:layout_width="160dp"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:choiceMode="singleChoice" />

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

这是MainActivity.java:

public class MainActivity extends AppCompatActivity {
    private Toolbar mToolbar;
    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ListView mActionList;
    private ActionBarDrawerToggle mDrawerToggle;

    private String[] mPlanetTitles;
    private String[] mActions;
    private int[] …

我从应用程序中删除了操作栏，所以我需要创建按钮来自己打开抽屉 Activity 上的按钮工作正常但是当我在片段应用程序中使用它时停止工作（当我调用片段时）

我在 Activity 中使用的代码（工作正常的代码）

 ImageButton btn = (ImageButton)findViewById(R.id.drawerButton);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
                drawer.openDrawer(Gravity.START);
            }
        });

fragment_achievements.xml

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="layout.AchievementsFragment">

    <ImageButton
        android:id="@+id/imageButton"
        android:layout_width="28dp"
        android:layout_height="29dp"
        android:layout_marginLeft="16dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:background="@android:color/transparent"
        android:scaleType="fitCenter"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@drawable/ic_menu_button" />

    <WebView
        android:id="@+id/web_ach"
        android:layout_width="409dp"
        android:layout_height="602dp"
        android:layout_marginBottom="-9dp"
        android:layout_marginLeft="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
