Progress Button Android

enter image description here

Android Button that morphs into a loading progress bar.

  • Fully customizable in the XML
  • Really simple to use.
  • Makes your app looks cooler =D

You can check how this library was implemented here: https://medium.com/p/9efee6e39711/



implementation 'br.com.simplepass:loading-button-android:1.14.0'

How to use

Animate and revert animation

Add the button in your layout file and customize it the way you like it.

            app:spinning_bar_width="4dp" <!-- Optional -->
            app:spinning_bar_color="#FFF" <!-- Optional -->
            app:spinning_bar_padding="6dp" <!-- Optional -->

Then, instanciate the button

    CircularProgressButton btn = (CircularProgressButton) findViewById(R.id.btn_id)

[do some async task. When it finishes]
//You can choose the color and the image after the loading is finished
	btn.doneLoadingAnimation(fillColor, bitmap); 
	[or just revert de animation]

Switch to determinant progress

You can switch between indeterminant and determinant progress:


- Show 'done' animation

When the loading animation is running, call:

//Choose the color and the image that will be show
circularProgressButton.doneLoadingAnimation(fillColor, bitmap);

- Revert the loading animation with different text or image

circularProgressButton.revertAnimation(new OnAnimationEndListener() {
                public void onAnimationEnd() {
                    circularProgressButton.setText("Seu texto aqui!");


circularProgressImageButton.revertAnimation(new OnAnimationEndListener() {
        public void onAnimationEnd() {

Configure XML

  • app:spinning_bar_width : Changes the width of the spinning bar inside the button
  • app:spinning_bar_color: Changes the color of the spinning bar inside the button
  • app:spinning_bar_padding: Changes the padding of the spinning bar in relation of the button bounds.
  • app:initialCornerAngle: The initial corner angle of the animation. Insert 0 if you have a square button.
  • app:finalCornerAngle: The final corner angle of the animation.

Avoid Memory Leaks

To avoid memory leaks is your code, you must dispose the buttons in the onDestroy method. Example:

override fun onDestroy() {


Be creative!

You can do a lot of fun stuff with this lib. Check this example:
