Question

任何人都知道我的错误，为什么我的工具栏的抽屉切换按钮没有打开导航抽屉？

我在onCreate

中使用了以下代码

        Toolbar toolbar;
        NavigationView mNavigationView;
        DrawerLayout mDrawerLayout;

        toolbar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        /**
         *Setup the DrawerLayout and NavigationView
         */
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
        mNavigationView = (NavigationView) findViewById(R.id.navstuff) ;

        /**
         * Setup click events on the Navigation View Items.
         */

        mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(MenuItem menuItem) {
                mDrawerLayout.closeDrawers();
                ...
                return false;
            }
        });

        /**
         * Setup Drawer Toggle of the Toolbar
         */

        ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout, toolbar,R.string.app_name,
                R.string.app_name);
        mDrawerLayout.addDrawerListener(mDrawerToggle);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        mDrawerToggle.syncState();

我的activity_main.xml

代码如下

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"

            </RelativeLayout>

        <android.support.design.widget.TabLayout

    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<android.support.v4.widget.DrawerLayout

    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:id="@+id/drawerLayout">

<android.support.design.widget.NavigationView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:id="@+id/shitstuff"
    app:itemTextColor="@color/colorPrimaryText"
    app:menu="@menu/drawermenu"
    android:layout_marginTop="?attr/actionBarSize"
    />

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

我想在我的CollapsingToolbarLayout中添加Navigation Drawer。但是切换按钮没有打开抽屉。此外，CollapsingToolbarLayout有时不会向上滚动。我正在使用minSdkVersion 21作为我的项目。

好的，我最后为activity_main，app_bar和content_main

创建了3 xml文件

<强> app_bar

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="@dimen/app_bar_height"

        android:fitsSystemWindows="true"

    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

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

            app:menu="@menu/drawermenu" />

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

我只是在我的ActivityMain class中没有做任何事情，但它的作品。我还在努力，希望没有错误。
