为什么文本视图不会占用整个表行的宽度是多少？ [英] Why does text view not take up the whole table row's width?

问题描述

我不知道，如果这个问题已经回答与否（我试着寻找，但没有找到任何东西）
这是我有一个问题关于布局的一部分。

I am not sure if this question has been answered or not(I tried looking but couldn't find anything) This is the portion of the layout that I have a question about.

对于选定的TextView，这里是XML code

For the selected textview, here is the xml code

我的问题是，这是为什么TextView中不占行的整个宽度。我假设，因为我使用了match_parent为layout_width该TextView中应承担其母公司，这是的TableRow的完整宽度。我试图寻找这种情况上来就TableLayout API（ http://developer.android。 COM /参考/安卓/空间/ TableLayout.html ），但其中match_parent中提到的唯一实例是在您没有它成一排，其宽度将作为一个元素添加到表格的布局情况被设置为match_parent。这是否有什么用行/列和行为在某种程度上改写match_parent？

My question is why is that textview not taking up the complete width of the row. I am assuming that because I used "match_parent" for the layout_width that the textview should take up the complete width of its parent, which is the TableRow. I tried looking this situation up on the TableLayout API (http://developer.android.com/reference/android/widget/TableLayout.html) but the only instance in which "match_parent" was mentioned was in the situation where you add an element to the table layout without it being in a row, its width will be set to "match_parent". Does this have anything to do with rows/columns and that behavior somehow overwriting "match_parent"?

推荐答案

分配
