How do I make Views fill the full width of their parent in my Android app?
提问by Alexander Trauzzi
I have the following layout defined for one of my Activities:
我为我的一项活动定义了以下布局：
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<TableRow android:id="@+id/TableRow01" android:layout_height="wrap_content" android:layout_width="fill_parent">
<EditText android:text="Resource Name" android:id="@+id/ResourceName" android:lines="1" android:isScrollContainer="false"></EditText>
</TableRow>
<TableRow android:id="@+id/TableRow02" android:layout_height="wrap_content" android:layout_width="fill_parent">
<Button android:id="@+id/Tile" android:text="Tile"></Button>
</TableRow>
</TableLayout>
The layout renders almost correctly, the only problem is that my text box and my button aren't occupying the full width of their respective rows.
布局几乎正确呈现，唯一的问题是我的文本框和我的按钮没有占据它们各自行的全宽。
I've tried specifying fill_parentfor the layout width properties, but to no avail, they still only occupy roughly half of the screen.
我试过指定fill_parent布局宽度属性，但无济于事，它们仍然只占屏幕的大约一半。
Documentation overall for Android so far has been great, but there are a few scenarios like this one where I hit an invisible wall! Thanks for all the help!
到目前为止，Android 的整体文档非常好，但有一些场景就像我碰到了一面隐形墙！感谢所有的帮助！

Try using android:stretchColumns="0"(when you define the TableLayout) or what ever is the index of the column that you would want to stretch.
尝试使用android:stretchColumns="0"（当您定义TableLayout）或您想要拉伸的列的索引。

Use android:layout_width="match_parent"in your tableRow views.
使用android:layout_width="match_parent"您的tablerow的意见。
Now you have different possibilities in your TableLayout seting the parameter android:stretchColumnsto:
现在，您可以在 TableLayout 中将参数设置android:stretchColumns为：
Value "*"views will have same width and will fill the row occupying the same space
Value "*"视图将具有相同的宽度并将填充占据相同空间的行
Value "0" or other integer-> First or element corresponding with the integer in a row will fill the row. The other view will have width in a same way of wrap_content
Value "0" or other integer-> 第一个或与一行中的整数对应的元素将填充该行。另一个视图的宽度与 wrap_content 相同
Example with a tablelayout of 3 tableRow with 2 views each:
具有 3 个 tableRow 的表格布局的示例，每个表格有 2 个视图：
Without setting android:stretchColumns:
没有设置android:stretchColumns：
[|TextView|EditText| ]
[|TextView|EditText| ]
[|TextView|EditText| ]
android:stretchColumns="*"
机器人：stretchColumns="*"
[| TextView | EditText |]
[| TextView | EditText |]
[| TextView | EditText |]
android:stretchColumns="0"
机器人：stretchColumns="0"
[| TextView |EditText|]
[| TextView |EditText|]
[| TextView |EditText|]
android:stretchColumns="1"
机器人：stretchColumns =“1”
[|TextView| EditText |]
[|TextView| EditText |]
[|TextView| EditText |]

Try this in the definition of your TableRow :
在你的 TableRow 的定义中试试这个：
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
