如果我有很多作为项目标签TextViews的,我以为我可以提取一切的共同关于他们成风格,在布局只使用
If I have a lot of TextViews serving as item labels, I thought I could extract everything that's common about them into a style, and in the layout use only
<TextView style="@style/label" android:text="Foo"/>
<TextView style="@style/label" android:text="Bar"/>
与风格,如:
<style name="label">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
</style>
但是当我这样做,它工作正常的仿真器和设备,但Android的XML编辑器抱怨说&LT;&TextView的GT;不设置所需layout_height属性。
是否有关于它为什么报告此警告的一些原因是什么?
But when I do this, it works fine on emulator and device, but the Android XML editor complains that "<TextView>" does not set the required layout_height attribute.
Is there some reason on why it is reporting this warning?
您是否尝试过清理项目?
Have you tried to clean the project?
我也使用在宽度和长度的一些XML文件同样的事情。这里有一个例子我的应用程序时,您可以看看:
I am using also the same thing on some XML files for the width and the length. Here is an example working on my app, you can have a look:
<TextView
android:id="@+id/viewdescription"
android:textIsSelectable="true"
android:layout_below="@+id/rating_bar_view"
android:minLines="8"
style="@style/description" />
和XML:
<style name="description">
<item name="android:layout_gravity">center_horizontal</item>
<item name="android:inputType">textMultiLine</item>
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:textSize">14sp</item>
<item name="android:textColor">@color/Black</item>
<item name="android:layout_marginRight">8dp</item>
<item name="android:layout_marginLeft">8dp</item>
