问题描述

我想在菜单中，单击要打开的抽屉权
我已经使用了以下code，但它不工作因为某些原因

  mDrawerToggle =新ActionBarDrawerToggle（getActivity（），mDrawerLayout，工具栏，R.string.drawer_open，
            R.string.drawer_close）{        @覆盖
        公共布尔onOptionsItemSelected（菜单项项）{
            如果（项目= NULL＆放大器;！＆安培; item.getItemId（）== R.id.more）{
                如果（mDrawerLayout.isDrawerOpen（Gravity.END））{
                    saveTo preferences（getActivity（），KEY_USER_LEARNED_DRAWER，mUserLearnedDrawer +）;
                    mDrawerLayout.closeDrawer（Gravity.END）;
                }其他{
                    mDrawerLayout.openDrawer（Gravity.END）;
                }
            }
            返回false;
        }
    };
 

请帮我出

  

解决它通过修改在MainActivity

  @覆盖
公共布尔onOptionsItemSelected（菜单项项）{
    开关（item.getItemId（））{
        案例R.id.action_settings：
            返回true;
        案例R.id.more：
            如果（notificationDrawerFragment.mDrawerLayout.isDrawerOpen（Gravity.END））{
                notificationDrawerFragment.mDrawerLayout.closeDrawer（Gravity.END）;
            }
            其他
            {notificationDrawerFragment.mDrawerLayout.openDrawer（Gravity.END）;
            }        默认：
            返回super.onOptionsItemSelected（项目）;
    }
}
 

解决方案

在主要活动中修改菜单选项解决以下

  @覆盖
公共布尔onOptionsItemSelected（菜单项项）{
    开关（item.getItemId（））{
        案例R.id.action_settings：
            返回true;
        案例R.id.more：
            notificationDrawerFragment.mDrawerLayout.openDrawer（Gravity.END）;        默认：
            返回super.onOptionsItemSelected（项目）;
    }
}

please help me out

SOLVED IT BY MODIFYING THE MAINACTIVITY

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_settings:
            return true;
        case R.id.more:
            if (notificationDrawerFragment.mDrawerLayout.isDrawerOpen(Gravity.END)){
                notificationDrawerFragment.mDrawerLayout.closeDrawer(Gravity.END);
            }
            else
            { notificationDrawerFragment.mDrawerLayout.openDrawer(Gravity.END);
            }

        default:
            return super.onOptionsItemSelected(item);
    }
}

解决方案

Solved the following by modifying the menu option within the main activity

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_settings:
            return true;
        case R.id.more:
            notificationDrawerFragment.mDrawerLayout.openDrawer(Gravity.END);

        default:
            return super.onOptionsItemSelected(item);
    }
}
