我觉得上面的代码看起来很好。我把它从www.example.com中移MainActivity.java，并做了一些修改，以便在这个片段中工作，但是现在我不明白为什么会出现下面的情况
当我单击同时作为按钮工作的ImageView时，我的应用程序崩溃。
我得到以下错误：

从异常堆栈跟踪中，

android.view.InflateException: Binary XML file line #2 in com.example.practice:layout/manage_acc_popup: Binary XML file line #2 in com.example.practice:layout/manage_acc_popup: Error inflating class com.google.android.material.card.MaterialCardView

然后，看第三行“起因于...”，这是

Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

因此，通过堆栈跟踪，您应该将您的Application或Activity主题设置为带有前缀Theme.MaterialComponents.*的任何样式，
下面是示例：
1.在res/value/style.xml中，

<style name="Theme.MaterialAppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- Custom item configurations -->
</style>

1.在AndroidManifest.xml中，

<application
     ...
     android:theme="@style/Theme.MaterialAppTheme">

或者

<activity
     ...
     android:theme="@style/Theme.MaterialAppTheme">

试试这个-
在style.xml/theme.xml中更改基本应用程序主题父级
将当前父主题替换为

parent="Theme.MaterialComponents.DayNight.NoActionBar"

问题就在这里：myDialog = new Dialog(getActivity().getApplicationContext());

  • 不要在那里使用应用程序Context，因为它没有主题。例如，只有new Dialog(getActivity())。如果这个Fragment在这个代码最初工作的MainActivity中，那么如果我按照你的描述正确的话，那应该就是你需要改变的全部。否则，你可能需要检查你的主题设置，正如下面的答案所建议的。
    这个答案取自Mike M.对问题的评论-谢谢，这是唯一真实的解决问题的方法。
