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 'https://jitpack.io' }
}
}Step 2. Add the dependency
dependencies {
implementation 'com.github.divyanshub024:AndroidDraw:v0.1'
}
There are two ways to use this library.
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)
}
}
}
}<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()
