为什么会发生 InflateException(由 ClassNotFoundException 引起)?
Why does an InflateException (Caused by ClassNotFoundException) occur?
我正在开发一个节拍器应用程序。我正在做让人们 select 节奏的部分。看起来像这样:
Tempo: <-- TextView
90 <-- EditText
--O------ <-- SeekBar
但是后来我改变了主意,把EditText
改成了TextView
。这是 xml:
的一部分
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="@dimen/all_text_size"
android:text="@string/tempo_text"/>
<TexView //This used to be an EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/tempo_text"/>
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:max="270"
android:id="@+id/tempo_seek"/>
</LinearLayout>
更改前,一切正常。但是在更改之后,tempo_text
TextView
有一个警告说:
Element TextView is not allowed here
我很困惑,如果上面的 TextView
是允许的,为什么 它 不被允许?所以我忽略了警告,认为这只是 Android Studio 的错误之一。当我运行应用程序时,出现异常:

你打错了 TexView
