使用 v7 ActionBarDrawerToggle 从右到左导航抽屉

Question

我正在我的应用中实现导航抽屉，我想使用 Material Design。

我使用以下参考来创建导航抽屉link。

对我来说效果很好。导航抽屉在从左到右滑动时工作正常。

现在我必须通过从右向左滑动来实现我的导航抽屉。我做了以下更改。听到是我的代码

这里我为 ActionBarDrawerToggle 使用了 android.support.v7.app.ActionBarDrawerToggle 导入。但是如果我使用 android.support.v4.app.ActionBarDrawerToggle 我可以使用它，那么问题是我没有得到材料设计中默认的后退按钮效果。

如果我使用 V4 库，那么我不能直接使用工具栏，还必须启用并显示主页按钮。

如果我使用 V7 库，基本上我无法制作 Gravity.RIGHT。如何覆盖该方法。

Answer 1

抽屉定位和布局是使用子视图上的 android:layout_gravity 属性控制的，对应于您希望抽屉从视图的哪一侧出现：左侧或右侧。 （或在支持布局方向的平台版本上开始/结束。）

在 XML 中将重力改为 RIGHT

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <FrameLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:baselineAligned="false" >
    </FrameLayout>

    <!-- Left drawer -->

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:choiceMode="singleChoice" />

    <!-- Right drawer -->

    <ListView
        android:id="@+id/right_drawer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:choiceMode="singleChoice" />
</android.support.v4.widget.DrawerLayout>

在java中

也添加这个

如果您使用的是由 Android Studio 创建的 Navigation Drawer 项目，那么 onOptionsItemSelected 会发生变化。由于他们创建了子类，因此您必须使用此代码

if (item != null && id == android.R.id.home) {
        if (mNavigationDrawerFragment.isDrawerOpen(Gravity.RIGHT)) {
            mNavigationDrawerFragment.closeDrawer(Gravity.RIGHT);
        } else {
            mNavigationDrawerFragment.openDrawer(Gravity.RIGHT);
        }
        return true;
}

接下来。在 NavigationDrawerFragment 类中，您必须创建 3 个方法：

方法一

public boolean isDrawerOpen(int gravity) {
    return mDrawerLayout != null && mDrawerLayout.isDrawerOpen(gravity);
}

方法二

public void closeDrawer(int gravity) {
    mDrawerLayout.closeDrawer(gravity);
}

方法三

public void openDrawer(int gravity) {
    mDrawerLayout.openDrawer(gravity);
}
