如果显示弹出菜单项RecyclerView,折叠工具栏布局始终会折叠

Question

我在我的Activity中实现了Collapsing ToolBar Layout.我在此活动中也创建了RecyclerView.我有问题,当我如何PopUp菜单项RecyclerView,折叠工具栏总是崩溃.

这是我的XML:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.ad.kostrad.mp.activity.GambarLokasiActvity">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        app:elevation="0dp"
        app:theme="@style/AppTheme.AppBarOverlay">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">


            <include
                layout="@layout/header_item_lokasi" />

          <include layout="@layout/custom_toolbar"/>

        </android.support.design.widget.CollapsingToolbarLayout>


    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_gambar_lokasi_actvity" />

</android.support.design.widget.CoordinatorLayout>

那么如何解决呢？

Answer 1

运用

PopupMenu popup = new PopupMenu(activity, v, Gravity.RIGHT);

如果点击靠近屏幕底部的项目,则无效.它仍然会尝试向上滚动以适应菜单.

实际上,支持库中似乎存在一个错误.要获得完整的修复,您现在可以替换:

import android.support.v7.widget.PopupMenu;

同

import android.widget.PopupMenu;

正如对类似问题的建议.弹出菜单将按预期工作.

Answer 2

我用替换来解决这个问题:

PopupMenu popup = new PopupMenu(activity, v);

至

 PopupMenu popup = new PopupMenu(activity, v, Gravity.RIGHT);
