我有一个自动完成文本视图。我想要一种运行“onClick”的方法。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"
             />

当它运行时，我得到错误。onClick 设置什么无关紧要，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 onClick 设置什么功能，我都会收到此错误。即使是具有空主体的函数也会导致此错误。

是什么导致了这个错误？
