Android Draw

A drawing view for your android application

Download

For information : checkout Sample App Code in repository.

Dependency

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 'https://jitpack.io' }
  }
 }

Step 2. Add the dependency

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

Usage

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, DrawingActivity::class.java)
startActivityForResult(intent, REQUEST_CODE_DRAW)

// Get bitmap in onActivityResult
override 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

Declaration

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