在res文件夹中创建一个drawable
文件夹,然后创建XML文件并将其命名为button_background
在XML文件中,您将定义按钮的形状,例如颜色,角落,笔触和填充,您可以在此处执行所有操作。以下代码与按钮类似:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid
android:color="#56b7cc" />
<stroke
android:width="1dp"
android:color="#70daf1" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#68c8dd"
android:endColor="#70daf1"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#70daf1" />
<corners
android:radius="4dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>
然后在你的布局中给出按钮:
<Button
android:id="@+id/Button1"
android:layout_width="50dip"
android:layout_height="40dip"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="107dp"
android:background="@drawable/button_background"
android:textColor="#ffffff"
android:text="ok" />
我制作了固定的宽度和高度,因此看起来像是图片,最重要的属性是
android:background="@drawable/button_background"
您可以通过更改颜色来修改它,填充更多地了解它here。希望这就是你要找的东西

如果您只想要按钮样式,则需要创建自己的按钮样式并基于,例如:
九片图片(using nine-patch image as Background of Button android,Button with 9-patch image background doesn't stretch correctly),
或基于形状(How to create custom button in Android using XML Styles)

style.xml
<style name="Button.Blue" parent="android:Widget.Holo.Light.Button">
<item name="android:background">@drawable/xbg_blue_button</item>
<item name="android:textAppearance">?android:attr/textAppearanceSmall</item>
<item name="android:textColor">@android:color/white</item>
<item name="android:textStyle">bold</item>
</style>
xbg_blue_button.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of pressed state. -->
<item android:state_focused="true" android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/btn_default_disabled_holo_light" />
<item android:state_focused="true" android:state_enabled="false" android:drawable="@drawable/btn_default_disabled_focused_holo_light" />
<item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/btn_default_pressed_holo_light" />
<item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/btn_default_normal_holo_light" />
<item android:state_focused="true" android:drawable="@drawable/btn_default_focused_holo_light" />
<item android:drawable="@drawable/btn_default_normal_holo_light" />
