适用于 Android 10 11 的 PopupMenu 崩溃

问题描述

Android 10,11 的以下代码崩溃适用于 7,8：

    PopupMenu popup = new PopupMenu(this,v);
    popup.setonMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem menuItem) {
            ...
            return true;
        }
    });
    MenuInflater inflater = popup.getMenuInflater();
    inflater.inflate(R.menu.menu_xxxx,popup.getMenu());
    popup.show();

这是崩溃日志：

解决方法

我使用的是旧图书馆 https://github.com/chrisjenx/Calligraphy 更新后，它工作正常。

,

解决方案 1：

在 gradle 中更新您的库并刷新您的导入。

解决方案 2：

有时菜单的行为会出现问题。

为此，删除 collapseActionView 或将其更改为 always app:showAsAction="always|collapseActionView" 到 app:showAsAction="always"
