抽屉布局固定菜单项 [英] Drawer layout with fixed menu item

问题描述

我们已经实施 DrawerLayout 这是工作的罚款。然而，我们想有是在屏幕的底部，并显示在抽屉里只有打开时，一个固定的菜单选项（注销）。页脚是不是一种选择，因为它会一直显示在菜单列表的最后一项，而我们总是希望它在菜单的底部。我们之所以能有与在 onDrawerOpened（），但平局的开关闭该按钮抽屉成为最顶层可见的按钮相对布局。请求焦点无助的抽屉打开动画甚至重点reqest后会发生

在任何情况下，我们正在寻找：

1. 无论是如何在底部随时添加这个菜单项
   或



2. 请在菜单显示抽屉打开后。

    公共无效onDrawerOpened（查看drawerView）{        。getActionBar（）的setTitle（的getTitle（））;
           invalidateOptionsMenu（）; //创建调用上prepareOptionsMenu（）;
           logoutButton.setVisibility（View.VISIBLE）;
           logoutButton.setFocusable（真）;
           logoutButton.requestFocus（）;
           logoutButton.requestLayout（）;
           //drawerLayout.addView(logoutView，0）;
       }
    

解决方案

您尝试与RelativeLayout的是给意外的结果，因为它不是内容的框架内。下面是我所做的：

 ＆LT; android.support.v4.widget.DrawerLayout
    的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：ID =@ + ID / drawer_layout
    机器人：layout_width =match_parent
    机器人：layout_height =match_parent＆GT;
    ＆LT;的FrameLayout
        机器人：ID =@ + ID / content_frame
        机器人：layout_width =match_parent
        机器人：layout_height =match_parent/＆GT;
＆LT; RelativeLayout的
    机器人：ID =@ + ID / relative_layout
   机器人：layout_width =240dp
    机器人：layout_height =match_parent
    机器人：layout_gravity =开始＆GT;    ＆LT; ListView控件
        机器人：ID =@ + ID / left_drawer
        机器人：layout_width =240dp
        机器人：layout_height =match_parent
        机器人：背景=＃111
        机器人：choiceMode =singleChoice
        机器人：分=@机器人：彩色/透明
        机器人：dividerHeight =0dp/＆GT;   ＆LT; RelativeLayout的
        机器人：layout_width =match_parent
        机器人：layout_height =WRAP_CONTENT
        机器人：layout_alignParentBottom =真正的＆GT;  ＆LT;的FrameLayout
        机器人：layout_width =match_parent
        机器人：layout_height =WRAP_CONTENT
        机器人：背景=机器人：ATTR / activatedBackgroundIndicator
        机器人：layout_alignParentBottom =真
        机器人：ID =@ + ID /持有者＆GT;        ＆LT;的TextView            机器人：layout_width =WRAP_CONTENT
            机器人：layout_height =WRAP_CONTENT
            机器人：背景=机器人：ATTR / activatedBackgroundIndicator
            机器人：重力=center_vertical
            机器人：ID =@ + ID / logout_item
            安卓了minHeight =机器人：ATTR /列表preferredItemHeightSmall
            机器人：paddingLeft =16DP
            机器人：paddingRight =16DP
            机器人：文字=@字符串/注销
            机器人：textAppearance =机器人：ATTR / textAppearanceListItemSmall
            机器人：文字颜色=＃FFF/＆GT;    ＆LT; /＆的FrameLayout GT;
    ＆LT; / RelativeLayout的＆GT;＆LT; / RelativeLayout的＆GT;＆LT; /android.support.v4.widget.DrawerLayout>
 

不要忘了运行HierarchyViewer摆脱不必要的的ViewGroup 。

We have implemented DrawerLayout which is working fine. However we would like a fixed menu option(logout) that has to be at the bottom of the screen and show up when the drawer opens only. The footer was not an option as it would always shows up as last item in the menu list rather we always want it at the bottom of the menu. We have been able to have a relative layout with the button that is made visible in the onDrawerOpened() but opening of the draw closes that button as the drawer becomes the topmost layer. Requesting focus does not help as the drawer open animation happens even after focus reqest

In any case, we are looking for:

1. Either how to add this menu item always at the bottom or

2. Make the menu show up after the drawer opens.

       public void onDrawerOpened(View drawerView) {
   
           getActionBar().setTitle(getTitle());             
           invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu();             
           logoutButton.setVisibility(View.VISIBLE);
           logoutButton.setFocusable(true);
           logoutButton.requestFocus();
           logoutButton.requestLayout();
           //drawerLayout.addView(logoutView, 0);
       }
   

解决方案

You attempt with the RelativeLayout was giving unexpected result since it wasnt inside the content frame. Here is what I did:

<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">
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
<RelativeLayout
    android:id="@+id/relative_layout"
   android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start" >

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />

   <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" >

  <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?android:attr/activatedBackgroundIndicator"
        android:layout_alignParentBottom="true"
        android:id="@+id/holder" >

        <TextView

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="?android:attr/activatedBackgroundIndicator"
            android:gravity="center_vertical"
            android:id="@+id/logout_item"
            android:minHeight="?android:attr/listPreferredItemHeightSmall"
            android:paddingLeft="16dp"
            android:paddingRight="16dp"
            android:text="@string/logout"
            android:textAppearance="?android:attr/textAppearanceListItemSmall"
            android:textColor="#fff" />

    </FrameLayout>
    </RelativeLayout>

</RelativeLayout>

</android.support.v4.widget.DrawerLayout>

Don't forget to run HierarchyViewer to get rid of unnecessary ViewGroup.
