<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:gravity="center"
android:background="#F66D08"
android:layout_width="match_parent"
android:layout_height="20dp">
</LinearLayout>
<LinearLayout
android:background="@drawable/introslidergradiant"
android:layout_width="match_parent"
android:layout_height="100dp"></LinearLayout>
</LinearLayout>
使用introslidergradiant.xml名称创建drawble res文件:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="90"
android:startColor="#A31720"
android:endColor="#E1350B"
android:type="linear" />
</shape>
</item>
</selector>
答案 3 :(得分:0)
您必须在drawable中创建一个xml文件
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<gradient
android:type="linear"
android:startColor="#FFFF820D"
android:endColor="#FFA32815"
android:angle="90"/>
</shape>
使用以下代码,或者您可以生成自己的渐变here只需设置颜色并选择android选项,它将为您生成渐变。
