如何将溢出菜单放置在工具栏下方而不是溢出菜单与工具栏重叠

问题描述

我为工具栏添加了shareActionProvider，我的问题是，一旦我点击共享图标，弹出菜单将覆盖工具栏内容，但是当我点击弹出菜单下列出的查看全部选项时，菜单，弹出菜单将完全位于工具栏下方.

I have added the shareActionProvider for the tool bar my problem is as soon as i tap on share icon the popup menu will cover the toolbar content but when i tap on see all option listed under the popup menu , the popup menu will perfectly settle below the tool bar.

我的要求是，当我点击共享"图标时，我的弹出菜单应立即填充在工具栏下方，而不是在我选择"查看全部"选项之后.

My requirement is as soon as i tap on share icon my popup menu should be populated below the tool bar not after i select the see all option.

menu.xml

<item
    android:id="@+id/menu_item_share"
    app:showAsAction="always"
    android:title="Share"
    android:icon="@drawable/abc_ic_menu_share_mtrl_alpha"/>

Java代码

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    MenuItem item = menu.findItem(R.id.menu_item_share);

    mShareActionProvider = new ShareActionProvider(getActivity()) {
        @Override
        public View onCreateActionView() {
            return null;
        }
    };

    MenuItemCompat.setActionProvider(item, mShareActionProvider);

    if (mShareActionProvider != null) {
        mShareActionProvider.setShareIntent(createShareIntent());
    }
}

style.xml

style.xml

<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
    <item name="actionOverflowMenuStyle">@style/PopupMenu</item>
</style>
<style name="PopupMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
    <item name="android:popupBackground">@color/colorPrimary</item>

    <!-- Required for pre-Lollipop. -->
    <item name="overlapAnchor">false</item>
    <item name="android:dropDownVerticalOffset">-4.0dip</item>

    <!-- Required for Lollipop. -->
    <item name="android:overlapAnchor">false</item>
    <item name="android:dropDownVerticalOffset">-4.0dip</item>
</style>

推荐答案

根据材料设计规范(请参见菜单"部分):

According to the Material Design specifications (see the Menus section):

所以您看到的是菜单的正确材料设计.

So what you are seeing is the correct Material design for menus.

要更改其主要样式，请使用<item name="actionOverflowMenuStyle">@style/OverflowMenu</item>，其中

To change it in your main style use <item name="actionOverflowMenuStyle">@style/OverflowMenu</item>, where

<style name="OverflowMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
  <!-- Required for pre-Lollipop. -->
   <item name="overlapAnchor">false</item>
   <item name="android:dropDownVerticalOffset">-4.0dip</item>
  <!-- Required for Lollipop. -->
   <item name="android:overlapAnchor">false</item>
   <item name="android:dropDownVerticalOffset">4.0dip</item>
</style>

对于棒棒糖样式，必须为values-v21.

For Lollipop style must be in values-v21.
