Question

我创建了一个具有RecyclerView的应用程序，每个项目都有一个选项菜单，该菜单将显示要共享的弹出窗口。一切正常，但当我尝试点击选项菜单时，它会崩溃。我收到一个奇怪的错误。我谷歌它，似乎我的主题有问题。我在互联网上尝试了很多解决方案，但没有一个能为我工作。

这是我的主题：

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>


<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:textColorPrimary">#ffffff</item>
    <item name="android:textColorSecondary">@color/about_us_link_text_color</item>
</style>

这是我的Adapter类

 holder.buttonViewOption.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PopupMenu popUp = new PopupMenu(context,holder.buttonViewOption);
            popUp.inflate(R.menu.option_menu);
            popUp.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {
                    switch (item.getItemId()){
                        case R.id.share:
                           Intent intent = new Intent(Intent.ACTION_SEND);
                            intent.setType("text/plain");
                            intent.putExtra(Intent.EXTRA_TEXT,news.get(position).getUrl());
                            intent.putExtra(Intent.EXTRA_SUBJECT,"check out this site");
                            context.startActivity(Intent.createChooser(intent,"share"));
                            break;
                        case R.id.save:
                            break;
                    }
                    return false;
                }
            });
            popUp.show();
        }
    });

option_menu：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
        <item
            android:id="@+id/share"
            android:title="Share" />

        <item
            android:id="@+id/save"
            android:title="Save" />
</menu>

我得到的错误是：

有人能告诉我我做错了吗？

Answer 1

试试这个

popUp.getMenuInflater().inflate(R.menu.option_menu, popUp.getMenu());

我希望这会对你有所帮助。

Answer 2

首先在适配器类中创建一个方法，如下所示。

 private void showPopup(View view, String url) {
     PopupMenu popup = new PopupMenu(activityContext, view);
     MenuInflater inflater = popup.getMenuInflater();
     inflater.inflate(R.menu.option_menu, popup.getMenu());
     popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()){
                    case R.id.share:
                       Intent intent = new Intent(Intent.ACTION_SEND);
                        intent.setType("text/plain");
                        intent.putExtra(Intent.EXTRA_TEXT,url);
                        intent.putExtra(Intent.EXTRA_SUBJECT,"check out this site");
                        activityContext.startActivity(Intent.createChooser(intent,"share"));
                        break;
                    case R.id.save:
                        break;
                }
                return true;
            }
        });
     popup.show();
 }

在你的 onBindViewHolder 方法中调用上面的函数，

holder.buttonViewOption.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        showPopup(view, news.get(holder.getAdapterPosition()).getUrl());
    }
});

Answer 3

而不是：

PopupMenu popUp = new PopupMenu(context, holder.buttonViewOption);

执行：

PopupMenu popUp = new PopupMenu(view.getContext(), holder.buttonViewOption);

选项菜单不适用于ThemeOverlay.AppCompat.Dark.ActionBar主题
