2 Getting Started Using the Library

2.1 Setup

Add the following to your build.gradle:

  repositories {
        jcenter()
  }
  
  dependencies {
      compile 'com.kyanogen.signatureview:signature-view:1.2'
  }

2.2 How to use view in xml layout

    <com.kyanogen.signatureview.SignatureView
            xmlns:sign="http://schemas.android.com/apk/res-auto"
            android:id="@+id/signature_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            sign:penSize="5dp"
            sign:backgroundColor="#ffffff"
            sign:penColor="#000000"
            sign:enableSignature="true"/>

First add Android XML namespace: xmlns:sign="http://schemas.android.com/apk/res-auto"
sign:penSize = set pen stroke size; default value is 3dp
sign:backgroundColor = set background color; default value is #FFFFFF
sign:penColor = set pen stroke color; default value is #4169e1
sign:enableSignature = enable/disable drawing signature on view
