将操作栏选项菜单向右对齐

Question

默认的应用程序图标和选项菜单项显示在操作栏的左侧。我希望选项菜单出现在菜单栏的右侧。

我已使用自定义视图在操作栏上向右显示其他按钮，但默认选项菜单项仍显示在左侧。

我在实现抽屉式导航时基本上面临这个问题。对于我的应用程序，用户应该能够点击放置在操作栏右端的菜单项，该菜单项将拉出导航抽屉。目前默认实现是在点击操作栏左侧的选项菜单时调用导航抽屉。

谢谢！

this is an xml

    <android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_gravity="right"

    android:layout_width="match_parent"
    android:layout_height="match_parent">

        <!-- As the main content view, the view below consumes the entire
             space available using match_parent in both dimensions. -->
        <FrameLayout
     android:id="@+id/content_frame"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >



        </FrameLayout>





                <ListView
                 android:id="@+id/right_drawer"
                 android:layout_width="400dp"
                 android:layout_height="600dp"
                 android:choiceMode="singleChoice"

    Java code :

    @Override
onCreate()
{
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        mDrawerList = (ListView) findViewById(R.id.right_drawer);

        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
                GravityCompat.START);
        mDrawerLayout.setAlpha((float)0.8);


        mDrawerList.setAdapter(adapter);
        mDrawerList.setClickable(false);
        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());



mDrawerToggle = new ActionBarDrawerToggle(this, // host Activity
                mDrawerLayout, // DrawerLayout object
                R.drawable.ic_drawer, // nav drawer image to replace 'Up' caret
                R.string.drawer_open, // "open drawer" description for
                                        // accessibility
                R.string.drawer_close // "close drawer" description for
                                        // accessibility
        ) {
            public void onDrawerClosed(View view) {
                // getActionBar().setTitle(mTitle);
                // invalidateOptionsMenu(); // creates call to
                // onPrepareOptionsMenu()
            }

            public void onDrawerOpened(View drawerView) {
                // getActionBar().setTitle(mDrawerTitle);
                // invalidateOptionsMenu(); // creates call to
                // onPrepareOptionsMenu()
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);


        if (savedInstanceState == null) {
            selectItem(0);
        }

}
        public boolean onCreateOptionsMenu(Menu menu) {
            // TODO Auto-generated method stub
            SubMenu filter = menu.addSubMenu(" ");
            subFilter = filter.getItem().setVisible(true);
            filter.setIcon(R.drawable.ico_filter);
            subFilter.setShowAsAction(android.view.MenuItem.SHOW_AS_ACTION_ALWAYS);
            return true;
        }

        public boolean onPrepareOptionsMenu(Menu menu) {
            // If the nav drawer is open, hide action items related to the content
            // view
            boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
            subFilter.setVisible(!drawerOpen);
            return super.onPrepareOptionsMenu(menu);
        }

        public boolean onOptionsItemSelected(MenuItem menuItem) {
            if (menuItem.equals(subFilter)) {
                if (mDrawerLayout.isDrawerOpen(Gravity.END) == true) {
                    mDrawerLayout.closeDrawers();

                } else {
                    mDrawerLayout.openDrawer(Gravity.END);

                }

            } else {
                onBackPressed();

            }

            return true;
        }
