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，因此如果打开右侧抽屉并且我按下 DrawerToggle 按钮 - 左侧抽屉也打开，并且重叠右边的抽屉。

我想得到几个解决方案:

1. 在右侧制作相同的 DrawerToggle 按钮，并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开关，反之亦然)。

我还没想好怎么做，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。

有人有什么想法吗？ 提前谢谢你。

最佳答案

这是一个双抽屉 Activity 的代码，它可以被其他 Activity 扩展以实现双抽屉，假设它们的布局类似于 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);
    }
}
