【中文标题】如何实现从右侧打开抽屉菜单【英文标题】：How to implement drawer menu open from right side 【发布时间】：2015-09-07 12:48:26 【问题描述】：我在this tutorial 之后创建了一个导航抽屉
但我需要的是，我需要从右侧打开相同的抽屉菜单。有人知道如何实现吗？
下面是我的xml
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer"
android:layout_
android:layout_
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<LinearLayout
android:layout_
android:layout_
android:orientation="vertical"
>
<include
android:id="@+id/toolbar"
layout="@layout/tool_bar"
/>
<FrameLayout
android:id="@+id/frame"
android:layout_
android:layout_>
</FrameLayout>
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_
android:layout_
android:layout_gravity="right"
app:headerLayout="@layout/header"
app:menu="@menu/drawer"
/>
在代码中
// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.openDrawer, R.string.closeDrawer)
@Override
public void onDrawerClosed(View drawerView)
// Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
super.onDrawerClosed(drawerView);
@Override
public boolean onOptionsItemSelected(MenuItem item)
if (item != null && item.getItemId() == android.R.id.home)
if (drawerLayout.isDrawerOpen(Gravity.RIGHT))
drawerLayout.closeDrawer(Gravity.RIGHT);
else
drawerLayout.openDrawer(Gravity.RIGHT);
return false;
@Override
public void onDrawerOpened(View drawerView)
// Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank
super.onDrawerOpened(drawerView);
;

android:layout_gravity="end" 代替 android:layout_gravity="start"
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_
android:layout_
android:layout_gravity="end"
app:headerLayout="@layout/header"
app:menu="@menu/drawer"
/>
//在你的java活动文件中添加这些行，它会工作
@Override
public boolean onOptionsItemSelected(MenuItem item)
switch (item.getItemId())
case android.R.id.home:
if (mDrawer.isDrawerOpen(Gravity.RIGHT))
mDrawer.closeDrawer(Gravity.RIGHT);
else
mDrawer.openDrawer(Gravity.RIGHT);
return true;
case R.id.action_settings:
return true;
最终更新：
我在您的示例项目（MainActivity.java）中更改了一些行，现在它正在工作，请使用此代码。
不要忘记在您的 xml 文件中写 android:layout_gravity="end" 代替 android:layout_gravity="start"。

【讨论】：
试过了，我收到了这个错误。java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
在滑动时它正在工作，但在点击汉堡图标时，它显示错误java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
我在我的导航抽屉上应用了我的代码，它在这里工作正常.. 唯一的区别是，我没有使用 onOptionItemSelected，我使用的是 setToolbarNavigationClickListener，我正在给你我的代码，让试试看。
我也试过这段代码。但不行
我仍然收到这个错误 java.lang.IllegalArgumentException: No drawer view found withgravity LEFT @user3339689 你能建议工具栏有什么问题吗？【参考方案2】：
这是可能的。您必须在导航抽屉中设置 android:layout_gravity="right" 并更改重力：
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close)
@Override
public boolean onOptionsItemSelected(MenuItem item)
if (item != null && item.getItemId() == android.R.id.home)
if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT))
mDrawerLayout.closeDrawer(Gravity.RIGHT);
else
mDrawerLayout.openDrawer(Gravity.RIGHT);
return false;
;
应该可以！

你能发布你的 DrawerLayout 声明和 xml 吗？
在滑动时它正在工作，但在点击汉堡图标时，它显示错误 java.lang.IllegalArgumentException: No Drawer view found withgravity LEFT –【参考方案3】：
实现左侧导航抽屉后，更改以下属性。
DrawerLayout 中的工具：openDrawer="start"
导航视图中的android:layout_gravity="end"
toolbar.setNavigationIcon (R.color.transparent);
mDrawerToggle.setDrawerIndicatorEnabled (false);
toolbar.setNavigationOnClickListener (new View.OnClickListener ()
@Override public void onClick(View view)
if (mDrawerLayout.isDrawerOpen (Gravity.END))
mDrawerLayout.closeDrawer (Gravity.END);
else
mDrawerLayout.openDrawer (Gravity.END);
);

【参考方案4】：试试这个对我有用
@Override
public boolean onOptionsItemSelected(MenuItem item)
switch (item.getItemId())
case android.R.id.home:
if (drawer.isDrawerOpen(Gravity.RIGHT))
drawer.closeDrawer(Gravity.RIGHT);
else
drawer.openDrawer(Gravity.RIGHT);
return true;
case R.id.action_settings:
// do what you want
return true;
return false;
