当ConstraintLayout正在膨胀时，必须提供layout_width属性

下面的XML文件将会膨胀，我不知道为什么会出现错误。下面是XML文件：

</android.support.constraint.ConstraintLayout>下面是logcat错误。

at android.view.LayoutInflater.inflate(LayoutInflater.java:426)我确信是这个constraintLayout导致了问题，因为#31错误中指示的行号正是声明此textView layout_width的行；textView layout_width在那里，那么它有什么可抱怨的呢？使用constrainLayout还有其他原因吗？
提前感谢！

执行此操作：
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="expandableItemStyle">@style/ExpandableItemStyle</item>
</style>
<style name="ExpandableItemStyle">
<item name="android:layout_height">@dimen/item_size</item>
<item name="android:layout_width">@dimen/item_size</item>
<item name="android:background">@drawable/bg_item_with_title</item>
<item name="android:layout_margin">@dimen/item_margin</item>
<item name="android:textColor">@color/gray</item>
<item name="android:textSize">@dimen/item_text_size</item>
</style>它能帮到你
