Android Draw

A drawing view for your android application


For information : checkout Sample App Code in repository.


Step 1 . Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {  repositories {   ...   maven { url '' }  } }

Step 2 . Add the dependency

dependencies {         implementation 'com.github.divyanshub024:AndroidDraw:v0.1' }


There are two ways to use this library.

1. Use Activity

You can call the Drawing Activity using startActivityForResult which will return you bitmap in byteArray. By using this method you will have all the features like change strokeWidth, change strokeColor, change Alpha, erase, redo, undo.

val intent = Intent(this,, REQUEST_CODE_DRAW)// Get bitmap in onActivityResultoverride fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {        if (data != null && resultCode == Activity.RESULT_OK) {            when(requestCode){                REQUEST_CODE_DRAW -> {                    val result= data.getByteArrayExtra("bitmap")                    val bitmap = BitmapFactory.decodeByteArray(result, 0, result.size)                    saveImage(bitmap)                }            }        }    }

2.Use DrawView


<com.divyanshu.draw.widget.DrawView        android:id="@+id/draw_view"        android:layout_width="match_parent"        android:layout_height="match_parent" />
  • To clear canvas
  • To set stroke width
// takes input as Floatdraw_view.setStrokeWidth(strokeWidth)
  • To set stroke alpha
// takes input as Intdraw_view.setAlpha(progress)
  • To set stroke color
  • To undo
  • To redo
