android - 如何在抽屉导航的右上角添加十字按钮

Question

我创建了一个抽屉导航，当用户点击 汉堡包 图标时，它会打开抽屉。我需要在 drawer 中添加一个关闭按钮。这就是我需要实现的。

我已经尝试过，但是无法在抽屉布局 上添加图像。这是我添加 Navigation Drawer 的代码。请指导我如何在抽屉的右上角添加图像。

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:id="@+id/base_layout">

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


</LinearLayout>


    <android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@+id/navigation_view"
        android:layout_gravity="start"
        android:background="@drawable/sidebg"
        app:menu="@menu/drawer_menu"
        app:itemTextColor= "#ffffff"
        app:headerLayout="@layout/navigation_drawer_header"
        android:gravity="bottom|left"
        android:dividerHeight="0dp"
        app:itemIconTint="@android:color/white"
        >

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




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

ActionBarDrawerToggle将解决您的问题:

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                mDrawerLayout,         /* DrawerLayout object */
                R.drawable.ic_drawer,  /* nav drawer icon to replace 'Up' caret */
                R.string.drawer_open,  /* "open drawer" description */
                R.string.drawer_close  /* "close drawer" description */
                ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                getActionBar().setTitle(mTitle);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                getActionBar().setTitle(mDrawerTitle);
            }
        };

        // Set the drawer toggle as the DrawerListener
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);

替代方法:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v4.widget.DrawerLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">


        <!--your layout here -->
    </android.support.v4.widget.DrawerLayout>


    <ImageView
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:id="@+id/im_close_btn"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:visibility="gone"
        android:src="@drawable/ic_close"/>
</RelativeLayout>
