DashedView
The easiest way to create a dashed or striped background on Android
The DashedView library allows you to create views with a dashed (or striped) background. Below are some examples of views created with this library. You can click on any example to see its code.
There is also a demo app for this library which allows you to see the look and feel of the DashedView on your own device:
Quick Start Guide 
If you don't have this already, add it to your root build.gradle file:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Then you can add the dependency to your app build.gradle file:
dependencies {
...
implementation 'com.github.MackHartley:DashedView:1.0.0'
}
Once that's finished you can declare a DashedView via XML:
<com.mackhartley.dashedview.DashedView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:dvDashAngle="45"
app:dvDashColor="#777"
app:dvDashWidth="4dp"
app:dvSpaceBetweenDashes="4dp"
app:dvViewCornerRadius="0dp" />
Usage
⚙️
The table below explains the 5 XML attributes you can set on the DashedView class:
| XML Attribute | Use |
|---|---|
dvDashAngle |
Sets the angle of the dashes. The angle is measured from the X axis of the view. |
dvDashColor |
Sets the color of the dashes. |
dvDashWidth |
Sets the width of the dashes. |
dvSpaceBetweenDashes |
Sets the width of the space between each dash. |
dvViewCornerRadius |
Sets the corner radius value for the DashedView. Useful when working with other views that have rounded corners. |
The DashedView also has a public method that allows you to set custom coloring for individual dashes:
| Public Method | Use |
|---|---|
setDashColorGenerator(...) |
This method takes a DashColorGenerator instance as a parameter which gives you access to the index of the current dash being drawn. Using that information you can specify logic for how each dash should be colored. |
interface DashColorGenerator {
@ColorInt fun getPaintColor(curIndex: Int, numDashes: Int): Int
}
