Buttons to fill width when using TableLayout
提问by Pentium10
I have a table having 2 rows each row having 3 buttons. How can I make the buttons to fill the space equally. In HTML I would give them 33% width.
我有一个表,每行有 2 行,有 3 个按钮。我怎样才能让按钮均匀地填充空间。在 HTML 中,我会给它们 33% 的宽度。
Also do you know any way I can create a view having 4 image buttons in a row as a grid layout, similar to the launcher.
你也知道我有什么方法可以创建一个具有 4 个连续图像按钮的视图作为网格布局,类似于启动器。

Try adding android:stretchColumns="*"
to your <TableLayout>
tag.

There is a more minimal example on stackoverflow also here: https://stackoverflow.com/a/2865558/265521
这里还有一个关于 stackoverflow 的最小示例:https: //stackoverflow.com/a/2865558/265521
Example:
例子:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<TableRow>
<Button
android:layout_width="0dip"
android:layout_height="match_parent"
android:text="Why is doing layouts on Android"
android:layout_weight="1"
/>
<Button
android:layout_width="0dip"
android:layout_height="match_parent"
android:text="so"
android:layout_weight="1"
/>
</TableRow>
<TableRow>
<Button
android:layout_width="0dip"
android:layout_height="match_parent"
android:text="damn"
android:layout_weight="1"
/>
<Button
android:layout_width="0dip"
android:layout_height="match_parent"
android:text="frustrating?"
android:layout_weight="1"
/>
</TableRow>
</TableLayout>

Set the TableRow layout_width to fill_parent and set a layout_weight of 1 on each button.
将 TableRow layout_width 设置为 fill_parent 并将每个按钮的 layout_weight 设置为 1。
The layout_weight works sort of like a percentage. If all of your items get the same number, they take the same percent of space. If one button has a weight of 2, and another has a weight of 1, then the first will take up twice as much space.
layout_weight 有点像百分比。如果您的所有项目都具有相同的编号,则它们占用的空间百分比相同。如果一个按钮的权重为 2,另一个按钮的权重为 1,则第一个按钮将占用两倍的空间。
If you haven't done so already, ready through the common layoutspage of the dev guide for a good intro to layouts.
如果您还没有这样做,请准备好阅读开发指南的通用布局页面,以了解布局的良好介绍。

So in conclusion of the posts, the right way to do it is to set the NumberOfTheColumns
:
因此,在帖子的总结中,正确的方法是设置NumberOfTheColumns
:
<tablelayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="NumberOfTheColumns"/>
You can set how many horizontal "piece" you need. If you have a 3x3 table:
您可以设置您需要多少个水平“片”。如果您有一张 3x3 的桌子:
<TableLayout
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/tableLayout1"
android:stretchColumns="3">
<TableRow
android:id="@+id/tableRow1">
<TextView
android:text="@string/EventTitle"
android:id="@+id/textView1"
android:gravity="center_vertical"
android:layout_column="0" />
<EditText
android:inputType="text"
android:id="@+id/editText3"
android:layout_weight="2"
android:layout_span="2"
android:layout_column="1" />
</TableRow>
<TableRow
android:id="@+id/tableRow2">
<TextView
android:text="@string/EventDateStart"
android:id="@+id/textView1"
android:gravity="center_vertical"
android:layout_column="0" />
<EditText
android:inputType="date"
android:id="@+id/editText1"
android:layout_weight="1"
android:layout_column="1"
android:layout_width="wrap_content" />
<EditText
android:inputType="time"
android:id="@+id/editText2"
android:layout_weight="1"
android:layout_column="2"
android:layout_width="match_parent" />
</TableRow>
<TableRow
android:id="@+id/tableRow3">
<TextView
android:text="@string/EventDateEnd"
android:id="@+id/textView1"
android:gravity="center_vertical"
android:layout_column="0"
android:layout_width="match_parent" />
<EditText
android:inputType="date"
android:id="@+id/editText1"
android:layout_weight="1"
android:layout_column="1" />
<EditText
android:inputType="time"
android:id="@+id/editText2"
android:layout_weight="1"
android:layout_column="2" />
</TableRow>
<TableRow>
<TextView
android:text="@string/Description"
android:id="@+id/textView1"
android:gravity="center_vertical"
android:layout_weight="3"
android:layout_span="3"
android:layout_column="0"
android:layout_width="match_parent" />
</TableRow>
<TableRow>
<EditText
android:inputType="textMultiLine"
android:id="@+id/editText3"
android:layout_height="50dp"
android:layout_weight="3"
android:layout_span="3"
android:layout_column="0"
android:layout_width="match_parent" />
</TableRow>
</TableLayout>
In this sample you can see a 5x3 table. You can set each column width by set how many pieces of the full table width do you need...
在此示例中,您可以看到一个 5x3 的表格。您可以通过设置您需要多少个完整的表格宽度来设置每个列的宽度...
