Question

我有一个autocompletetextview。我想要一个方法来运行“onClick”。这是我的XML：

        <AutoCompleteTextView
            android:id="@+id/GivenByBox"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:onClick="setupMiranda"
            android:gravity="left"
             />

运行此操作时，我会收到错误消息。无论onClick设置为什么，它总是会导致错误。如果我删除android：onclick行一切正常，但这不是我想要的。

以下是logCat的摘录：

无论在Click上设置了什么功能，我都会收到此错误。即使是具有空体的函数也会导致此错误。

导致此错误的原因是什么？

AutocompleteTextView中的“onClick”会导致错误
