DrawerLayout双抽屉(左右抽屉同时)

Question

我有一个应用程序,我想在其中实现一个双抽屉 - 一个来自左边,一个来自右边.左抽屉用于app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>

你可以在这里清楚地看到"left_drawer"和"right_drawer",以及它们各自的重力 - "开始"和"结束"这实际上是有效的!你可以将它们全部拉出来.

问题是,当我实现DrawerToggle时 - 它只打开左抽屉,而不是关闭右抽屉,所以如果打开右抽屉我按下DrawerToggle按钮 - 左抽屉也打开,并重叠右抽屉.

我想要获得以下几种解决方案:

1. 在右侧创建相同的DrawerToggle按钮,其行为和动画与左侧相同.
2. 将抽屉放在抽屉的另一侧,我试图打开 - 自动关闭(如果左抽屉打开,我按下右抽屉的拨动开关,反之亦然).

我还没有想到如何做到这一点,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.

有人有主意吗？先感谢您.

这是双抽屉活动的代码,可以通过其他活动扩展来实现双抽屉,假设它们的布局类似于OP所支持的布局.

    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);
    }
}

Answer 2

你可以在ToggleButton的处理程序中调用它,例如:

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

其中mDrawer是您需要打开的特定抽屉的引用(无论是视图还是布局),在您的情况下,您希望显示实际的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>

这是我的所有想要阻止抽屉指示器动画的人的简短解决方案,如果他们滑动右视图.只需像这样实现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
       }
    }
};

Answer 5

使用onOptionsItemSelected()中要关闭的任何抽屉(当打开另一个抽屉时)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的侦听器对象
