在一个应用程序,我的工作,我有几个ImageButtons。每个的ImageButton具有背景和内容在一个可拉伸的形式。眼下是绘制在的ImageButton的范围内最大规模,但我希望它缩小,所以我需要添加一些填充。问题是,当我尝试这样做,它不会有任何影响。我的XML是如下每个ImageButton的:
In an app I am working on, I have several ImageButtons. Each ImageButton has a background and content in the form of a drawable. Right now the drawable is at maximum size within the confines of the ImageButton, but I want it to scale down so I need to add some padding. The thing is that when I try to do that, it doesn't have any effect. My XML is as follows for each ImageButton:
<ImageButton
android:id="@+id/button_zero"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:padding="10dip"
android:src="@drawable/button_zero"
android:background="@drawable/button_background" />
任何想法,为什么填充什么都不做?
Any ideas why the padding doesn't do anything?
完整的XML code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

tools:context=".Main" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<!-- Row One -->
<LinearLayout

</LinearLayout>
... same for other rows
</LinearLayout>
您已经添加到您的ImageButton定义
You have to add to Your ImageButton definition
android:scaleType="fitCenter"
或其他scaleType像fitXY,因为默认图像尝试缩放尽可能和忽略填充
or other scaleType like fitXY, because by default image try to scale as much as possible and ignore padding
