How to use

Animate and revert animation

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

  <br.com.simplepass.loading_button_lib.customViews.CircularProgressButton
    	    android:id="@+id/btn_id"
    	    android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/circular_border_shape"
            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)

    btn.startAnimation();
    
[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]
	btn.revertAnimation();

- 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() {
                @Override
                public void onAnimationEnd() {
                    circularProgressButton.setText("Seu texto aqui!");
                }
            });

or

circularProgressImageButton.revertAnimation(new OnAnimationEndListener() {
        @Override
        public void onAnimationEnd() {
            progressButton.setImageDrawable(R.drawable.image);
        }
    });

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() {
        super.onDestroy()

        progressButton.dispose()
 }

Be creative!

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

You can find the code for the animation inside this repo.
