如何覆盖菜单栏以出现在应用程序栏上? [英] How can I override my menu bar to come on my application bar?

问题描述

我的活动中有回收站视图+ viewpager +工具栏.当我在回收站视图中长按该行时，它应该显示一个带有删除选项的菜单栏.但这就是我得到的.关于它为什么出现在我的应用程序名称上方的任何想法?

I have recycler view + viewpager + toolbar in my activity. When I long click on the row in recycler view it should show me a menu bar with a delete option. But this is what I get. Any ideas as to why it is coming above my application name?

这是我主要活动的xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.kaad.sampleproject.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/main_activity_tool_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    <android.support.design.widget.TabLayout
        android:id="@+id/main_activity_tablayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/main_activity_tool_bar"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:tabIndicatorColor="#ff00ff"
        app:tabMode="fixed"
        app:tabSelectedTextColor="#ffffff"
        app:tabTextColor="#d3d3d3" />

    <android.support.v4.view.ViewPager
        android:id="@+id/main_activity_viewpager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/main_activity_tablayout" />

</RelativeLayout>

我保留了一个关于"菜单，该菜单由于某种原因从未显示过: 这是我两个菜单的xml:

I kept an add and about menu which never gets displayed for some reason: Here is the xml of both my menus:

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/menu_bar_main"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    tools:context=".MainActivity">
    <item
        android:id="@+id/menu_item_new"
        android:icon="@drawable/ic_add_white_36dp"
        android:title="@string/menu_new"
        app:showAsAction="ifRoom|withText" />
    <item
        android:id="@+id/menu_item_about"
        android:title="@string/menu_about"
        app:showAsAction="never" />
</menu>

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/menu_bar_delete"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    tools:context=".MainActivity">
    <item android:id="@+id/menu_item_delete"
        android:icon="@android:drawable/ic_menu_delete"
        android:title="@string/delete" />
</menu>

我的样式的xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

        <!--<item name="colorPrimary">#FF595951</item>-->
        <!--<item name="colorPrimaryDark">#FF5C5C5C</item>-->
        <!--<item name="colorAccent">#FFCCCCCC</item>-->
        <!--<item name="android:textColorPrimary">#FF0FF0</item>-->
        <item name="windowActionBar">true</item>
        <item name="windowNoTitle">true</item>
    </style>

这是主要活动:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_main);

        database = new Database(this);
        categories = database.getCategories();

        myToolbar = (Toolbar) findViewById(R.id.main_activity_tool_bar);
        setSupportActionBar(myToolbar);


        // Get the ViewPager and set it's PagerAdapter so that it can display items
        myViewPager = (ViewPager) findViewById(R.id.main_activity_viewpager);
        myPagerAdapter = new MyPagerAdapter(getSupportFragmentManager(), MyMainActivity.this, categories);
        myViewPager.setAdapter(myPagerAdapter);

        // Give the TabLayout the ViewPager
        myTabLayout = (TabLayout) findViewById(R.id.main_activity_tablayout);
        myTabLayout.setupWithViewPager(myViewPager);

        // Iterate over all tabs and set the custom view
        for (int i = 0; i < myTabLayout.getTabCount(); i++) {
            TabLayout.Tab myTab = myTabLayout.getTabAt(i);
            myTab.setCustomView(myPagerAdapter.getTabView(i));
        }
        bus.getInstance().register(this);
    }

这就是我在主处方片段中调用菜单栏的方式

 public class CustomMultiSelectorCallback extends ModalMultiSelectorCallback {

        private int count;
        public CustomMultiSelectorCallback(MultiSelector multiSelector) {
            super(multiSelector);
        }

        @Override
        public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
            super.onCreateActionMode(actionMode, menu);
            count = 0;
            actionMode.getMenuInflater().inflate(R.menu.list_item_delete, menu);
            return true;
        }

推荐答案

所以我已经解决了其中一个问题.这是我在代码中编辑的内容，用于显示工具栏中的添加和关于按钮.

So I have solved one of the problems. This is what I edited in my code to display add and about buttons in the toolbar.

首先，在片段的onCreate中，添加以下行:

First, in your onCreate in the fragments, add this line:

setHasOptionsMenu(true);

其次，以您的样式将主题更改为具有NoActionBar的主题.就我而言，我是这样做的:

Second, in your styles, change your theme to something which has NoActionBar. In my case I did this:

<style name="AppThemeOfStyles"parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">#FF595951</item>
        <item name="colorPrimaryDark">#FF5C5C5C</item>
        <item name="colorAccent">#FFCCCCCC</item>
        <item name="android:textColorPrimary">#FF0FF0</item>
        <item name="windowActionBar">true</item>
        <item name="windowNoTitle">true</item>
    </style>

我也将主题的名称从AppTheme更改为样式的AppTheme，因为AppTheme已经定义了主题.因此最好将您的主题名称更改为其他名称.

I also changed the name of my theme from AppTheme to AppTheme of styles since AppTheme is already a theme defined. So better to change your theme name to something else.

这导致我们得出以下结果:

This leads us to the result below:

但是我的删除仍然在longpress的工具栏顶部.

But my delete is still coming on the top of the toolbar on longpress.

任何建议，建议将不胜感激:)

Any suggestions, advice will be appreciated :)

更新: 在主题中使用此选项可使叠加层起作用: <item name="windowActionModeOverlay">true</item>

UPDATED: Use this in your theme for the overlay to work: <item name="windowActionModeOverlay">true</item>

这是最终结果:
