直接上程式碼

1，虛線xml檔案

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
    <stroke android:width="@dimen/dp1"
android:color="@color/doe"
android:dashWidth="@dimen/dp5"
android:dashGap="@dimen/dp5"/>
    <size android:height=
 
"1dp"/>
</shape>

2，引用的虛線view

<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layerType="software"
android:background="@drawable/dotted_line_shape"/>
