我有一个应用程序，我想在其中实现一个双抽屉 - 一个来自左侧，一个来自右侧。左抽屉用于应用导航，右抽屉用于结果过滤。

所以，布局是这样的：

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

        <GridView
            android:id="@+id/gridview"
            style="@style/GridViewStyle"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:gravity="center"
            android:horizontalSpacing="7dp"
            android:stretchMode="columnWidth"
            android:verticalSpacing="7dp" />
    </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" />

    <ListView
        android:id="@+id/right_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>

您可以在这里清楚地看到“left_drawer”和“right_drawer”，以及它们各自的重力——“start”和“end”，这确实有效！你可以把它们都拉出来。

问题是，当我实现 DrawerToggle 时 - 它只打开左侧抽屉，而不关闭右侧抽屉，所以如果打开右侧抽屉并且我按下 DrawerToggle 按钮 - 左侧抽屉也打开，并与右侧抽屉重叠.

我想得到几个解决方案：

  1. 在右侧制作相同的 DrawerToggle 按钮，具有与左侧相同的行为和动画。
  2. 将抽屉放在我要打开的抽屉的另一侧 - 自动关闭（如果左侧抽屉打开并且我按下右侧抽屉的拨动开关，反之亦然）。

而且我还没有想出如何做到这一点，因为 DrawerToggle 接受 DrawerLayout 本身作为参数，而不是单个抽屉......

我正在使用支持库。

有人有想法么？先感谢您。

这是一个双抽屉活动的代码，它可以由其他活动扩展以实现双抽屉，假设它们具有类似于 OP 提出的布局。

    public class DoubleDrawerActivity extends ActionBarActivity {

    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    private View mLeftDrawerView;
    private View mRightDrawerView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

    @Override
    protected void onStart() {
        super.onStart();

        if(mDrawerLayout == null || mLeftDrawerView == null || mRightDrawerView == null || mDrawerToggle == null) {
            // Configure navigation drawer
            mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
            mLeftDrawerView = findViewById(R.id.left_drawer);
            mRightDrawerView = findViewById(R.id.right_drawer);
            mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_navigation_drawer, R.string.drawer_open, R.string.drawer_close) {

                /** Called when a drawer has settled in a completely closed state. */
                public void onDrawerClosed(View drawerView) {
                    if(drawerView.equals(mLeftDrawerView)) {
                        getSupportActionBar().setTitle(getTitle());
                        supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                        mDrawerToggle.syncState();
                    }
                }

                /** Called when a drawer has settled in a completely open state. */
                public void onDrawerOpened(View drawerView) {
                    if(drawerView.equals(mLeftDrawerView)) {
                        getSupportActionBar().setTitle(getString(R.string.app_name));
                        supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                        mDrawerToggle.syncState();
                    }                   
                }

                @Override
                public void onDrawerSlide(View drawerView, float slideOffset) {
                    // Avoid normal indicator glyph behaviour. This is to avoid glyph movement when opening the right drawer
                    //super.onDrawerSlide(drawerView, slideOffset);
                }
            };

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

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);

        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {

        // If the nav drawer is open, hide action items related to the content view
        for(int i = 0; i< menu.size(); i++)
            menu.getItem(i).setVisible(!mDrawerLayout.isDrawerOpen(mLeftDrawerView));

        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch(item.getItemId()) {
            case android.R.id.home:
                mDrawerToggle.onOptionsItemSelected(item);

                if(mDrawerLayout.isDrawerOpen(mRightDrawerView))
                    mDrawerLayout.closeDrawer(mRightDrawerView);

                return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

您可以在 ToggleButton 的处理程序中这样调用它，例如：

mDrawerLayout.openDrawer(mDrawer);
mDrawerLayout.closeDrawer(mDrawer);

mDrawer 是对您需要打开的特定抽屉（无论是视图还是布局）的引用，在您的情况下，是您希望显示的实际 ListView。

您可以使用NavigationView材料设计。

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view2"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer1" />

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

这是我的简短解决方案，适用于所有希望在滑动右侧视图时阻止抽屉指示器动画的人。像这样简单地实现onDrawerSlide方法。

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer_white, 0, 0) {

    @Override
    public void onDrawerClosed(View view) {
       invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
    }

    @Override
    public void onDrawerOpened(View drawerView) {
       invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
    }

    @Override
    public void onDrawerSlide(View drawerView, float slideOffset) {
       if (drawerView == mSlidingMenuNavigationList) {
           super.onDrawerSlide(drawerView, slideOffset);
       }
       else {
          // do nothing on all other views
       }
    }
};

在 onOptionsItemSelected() 中使用要关闭的任何抽屉（打开另一个抽屉时）的重力常数（Gravity.LEFT 或 Gravity.RIGHT），如下所示。

public boolean onOptionsItemSelected(MenuItem item) {
    if (mDrawerToggle.onOptionsItemSelected(item)) {

       // Close the right side drawer if visible
       if(mDrawerLayout.isDrawerVisible(Gravity.RIGHT)) {
           mDrawerLayout.closeDrawer(Gravity.RIGHT);
       }
       return true;
    }

    // Regular stuff
    switch (item.getItemId()) {
    case R.id.action_example:
        Toast.makeText(getActivity(), "Example action.", Toast.LENGTH_SHORT).show();
        return true;
    }

    return super.onOptionsItemSelected(item);
}

mDrawerToggle = 实现 DrawerLayout.DrawerListener 的监听器对象

制作一个自定义项目并将其添加到右侧，将右侧的抽屉传递给它。

final ToggleButton ic_nav = (ToggleButton) customNav.findViewById(R.id.ic_nav);

        ic_nav.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View arg0)
            {
                if ( mDrawerLayout.isDrawerOpen(mDrawerList) && arg0.isSelected()) {
                    mDrawerLayout.closeDrawer(mDrawerList);
                    arg0.setSelected(false);
                }
                else if (!mDrawerLayout.isDrawerOpen(mDrawerList) && !arg0.isSelected()){
                    mDrawerLayout.openDrawer(mDrawerList);
                    ic_nav.setSelected(false);
                    arg0.setSelected(true);
                }
            }
        });

我已经解决了在 onOptionsItemSelected 方法中添加此代码：

switch (item.getItemId()) {
    case android.R.id.home:
        if (mDrawerLayout.isDrawerOpen(mDrawerList_right)){
            mDrawerLayout.closeDrawer(mDrawerList_right);
        }
        mDrawerLayout.openDrawer(mDrawerList_left);
    }
    break;
case R.id.action_drawer:
        if (mDrawerLayout.isDrawerOpen(mDrawerList_left)){
            mDrawerLayout.closeDrawer(mDrawerList_left);
        }
        mDrawerLayout.openDrawer(mDrawerList_right);
    }
default:
    break;
}

我添加了一个操作按钮并覆盖了操作栏的主页按钮
