有两种解决方案：
1、使用9-patch 图片，制作一个阴影部分的图片，然后横向拉伸即可
?
2、使用layer-list
在res/drawable下，新建background_with_shadow.xml文件，该文件代码如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | <?xml?version="1.0"?encoding="utf-8"?><layer-list?xmlns:android="<a href="http://schemas.android.com/apk/res/android"?>" target="_blank">http://schemas.android.com/apk/res/android"?></a>? ????<!--?bottom?shadow?-->????<item>????????<shape?android:shape="rectangle"?>????????????<!--?from?top?to?bottom?-->????????????<gradient????????????????android:angle="90"????????????????android:centerColor="#bbbbbb"????????????????android:endColor="#d5d5d5"????????????????android:startColor="#a9a09d"?/>????????????<corners?android:radius="5dp"?/>????????</shape>????</item>?????????<!--?content?-->????<item?android:bottom="2dp">????????<shape?android:shape="rectangle"?>????????????<solid?android:color="#50c1e9"?/>????????????<corners?android:radius="5dp"?/>????????</shape>????</item>? </layer-list> |
使用background_with_shadow.xml文件
? ? 假设有bottom_shadow.xml文件，内容如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | <?xml?version="1.0"?encoding="utf-8"?><LinearLayout?xmlns:android="<a href="http://schemas.android.com/apk/res/android""?target="_blank">http://schemas.android.com/apk/res/android"</a>????android:layout_width="match_parent"????android:layout_height="match_parent"????android:orientation="vertical"????android:background="#bfbfbf">?????????<LinearLayout?????????android:layout_marginTop="40dp"????????android:layout_width="match_parent"????????android:layout_height="40dp"????????android:orientation="vertical"?????????android:background="@drawable/background_with_shadow">????</LinearLayout>?????????<TextView?????????android:layout_marginTop="20dp"????????android:layout_marginLeft="20dp"????????android:layout_width="match_parent"????????android:layout_height="wrap_content"????????android:text="短址赚"/>?????</LinearLayout> |
