我想提出四排,每排三个按钮,并在按钮的底部有两个文本视图。我想他们都被均匀分布,但他们都没有,我不知道为什么。
I am trying to make four rows of three buttons each, and at the bottom of the buttons are two text views. I would like for them all to be spaced evenly but they aren't and I am not sure why.
下面是code。在我的main.xml中的文件。
Here is the code in my main.xml file.
<?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_width="wrap_content"
android:layout_height="wrap_content">
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button01"
android:text="@string/str_1"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button02"
android:text="@string/str_2"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button03"
android:text="@string/str_3"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button04"
android:text="@string/str_4"/>
</TableRow>
<TableRow android:id="@+id/TableRow02"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

android:text="@+string/str_5"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button06"
android:text="@+string/str_6"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button07"
android:text="@+string/str_7"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button08"
android:text="@+string/str_8"/>
</TableRow>
<TableRow android:id="@+id/TableRow03"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button09"
android:text="@+string/str_9"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button10"
android:text="@+string/str_10"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button11"
android:text="@+string/str_11"/>
<Button android:onClick="button_click"
android:layout_weight="1"
android:id="@+id/Button12"
android:text="@+string/str_12"/>
</TableRow>
<TableRow android:id="@+id/TableRow04"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
<TextView android:text="@+id/TextView01"
android:layout_weight="1"
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<TextView android:text="@+id/TextView02"
android:layout_weight="1"
android:id="@+id/TextView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
</TableRow>
</TableLayout>
我的文字的看法有以下code:
My text views have the following code:
TextView t = (TextView)findViewById(R.id.TextView01);
TextView t2 = (TextView)findViewById(R.id.TextView02);
t.setTextSize(24);
t2.setTextSize(24);
当我运行我的程序,我得到:
When I run my program I get:
确定,所以,以帮助这个添加安卓stretchColumns =0,1,2,3
在你的表布局这将使按钮甚至大小。
Ok so to help out with this add android:stretchColumns="0,1,2,3"
in your Table Layout which would make buttons even sized.
其次添加机器人:layout_span =2
来您的两个文本视图
Secondly add a android:layout_span="2"
to both of your text views.
下面有你最后的code:
Heres you a final code:
<!-- NOTICE STRETCHCOLUMNS ATTRIBUTE-->
<TableLayout android:id="@+id/TableLayout01"
xmlns:android="http://schemas.android.com/apk/res/android"
android:stretchColumns="0,1,2,3"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
.
.
.
.
.
<!-- NOTICE LAYOUT_SPAN ATTRIBUTE-->
<TextView android:text="@+id/TextView01"
android:layout_weight="1"
android:id="@+id/TextView01"
android:layout_span="2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<TextView android:text="@+id/TextView02"
android:layout_weight="1"
android:id="@+id/TextView02"
android:layout_span="2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
如果您正在设置文字大小编程,使您的TextViews均匀分布的,当你拥有它不需要机器人:layout_span
设置
If you are setting the text size programmatically to make your TextViews evenly spaced, its not needed when you have android:layout_span
set.
