通过这个XML：

<TableRow >
    <Button
        android:id="@+id/buttonNext"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Next"
        android:textAppearance="?android:attr/textAppearanceMedium" />
</TableRow>

我希望WRAP_CONTENT只有一样宽必要在按钮上显示的文字是，但按钮垄断了屏幕的整个宽度...？

I would expect "wrap_content" to only be as wide as necessary to display the text on the button, but the button monopolizes the entire width of the screen...?

推荐答案

您的问题是，在你的XML宽度规格将被忽略。从文档来的TableRow 的：

Your problem is that the width specification in your xml is ignored. From the docs for TableRow:

通过tablerow的孩子不需要指定layout_width和layout_height在XML文件中的属性。的TableRow总是强制这些值分别MATCH_PARENT和WRAP_CONTENT。

The children of a TableRow do not need to specify the layout_width and layout_height attributes in the XML file. TableRow always enforces those values to be respectively MATCH_PARENT and WRAP_CONTENT.

P.S。你有一个令人信服的理由使用绝对像素？这通常被认为是不好的做法。

P.S. Did you have a compelling reason to use absolute pixels? That's generally considered bad practice.
