在API级别10或更低级别上运行时，为什么我的TableLayout无法正常显示？

Question

我的应用使用TableLayout向用户显示一些数据。当我在API级别为11或更高的设备（或AVD）上运行应用程序时，表格会完全按预期显示。

但是，只要我使用API​​级别为10或更低的AVD，TableView就不再显示边距，也不会正确执行android:layout_width="wrap_content" - 标记。

有谁知道，为什么会这样，以及如何解决它？边距不是第一优先（它看起来很丑陋），但内容包装是：由于表没有按预期包装整个内容，用户将无法获得他应该得到的所有信息！

这是我的XML：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    </ScrollView>
 </RelativeLayout>

要解决此问题，您需要在表格布局上设置重力。由于您在所有方面都使用了边距，因此您可能需要android:gravity="center"。出于某种原因，API＆lt;如果你没有为TableLayout设置重力，那么就会忽略边距。
