How do I reduce the inner padding around the text within an Android button object?
提问by Imran NZ
So, at the moment I have a button which looks like the first image above. How do I reduce the padding around the text inside the button itself (To look more like the second image)?
所以，目前我有一个按钮，看起来像上面的第一张图片。如何减少按钮本身内部文本周围的填充（看起来更像第二张图片）？
Layout width and height is set as:
布局宽度和高度设置为：
android:layout_width="match_parent"
android:layout_height="wrap_content"
The custom style shape has parameters"
自定义样式形状有参数"
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
With the rest just being color attributes and radii values.
其余的只是颜色属性和半径值。
Just to make it clear, I want the frame of the button to hug the "Login" text closer.
只是为了清楚起见，我希望按钮的框架更靠近“登录”文本。
All help and feedback is greatly appreciated. Thanks.
非常感谢所有帮助和反馈。谢谢。

It took me forever to find this but the "padding" around the text in a button isn't really padding at all. The default Widget.Button style includes a minHeight property. Changing minHeight on the button will allow you to adjust padding as expected.
我花了很长时间才找到这个，但是按钮中文本周围的“填充”根本不是真正的填充。默认的 Widget.Button 样式包括 minHeight 属性。更改按钮上的 minHeight 将允许您按预期调整填充。
<Button
android:id="@+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/test"
android:textColor="@color/black"
android:minHeight="40dip"/>
<style name="Widget.Holo.Button" parent="Widget.Button">
<item name="android:background">@android:drawable/btn_default_holo_dark</item>
<item name="android:textAppearance">?android:attr/textAppearanceMedium</item>
<item name="android:textColor">@android:color/primary_text_holo_dark</item>
<item name="android:minHeight">48dip</item>
<item name="android:minWidth">64dip</item>
</style>

If you want a smaller top and bottom padding, use this:
如果您想要较小的顶部和底部填充，请使用：
android:paddingTop="2dp"
android:paddingBottom="2dp"

在您的自定义 shape.xml 文件中试试这个
