• if you want to do some extra things when buttons are clicked then you neet to implement OnEventListener.

  Java code:
  
  public class MainActivity extends AppCompatActivity {
private PaintView paintView;
 @Override
 protected void onCreate(final Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);
     paintView = findViewById(R.id.paintview);
     paintView.setEvantListenar(new OnEventsListener() {
         @Override
         public void OnRedClicked() {
             Toast.makeText(getApplicationContext(),"red is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnBlueClicked() {
             Toast.makeText(getApplicationContext(),"blue is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnYellowClicked() {
             Toast.makeText(getApplicationContext(),"yellow is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnGreenClicked() {
             Toast.makeText(getApplicationContext(),"green is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnBlackClicked() {
             Toast.makeText(getApplicationContext(),"black is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnBrownClicked() {
             Toast.makeText(getApplicationContext(),"brown is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnEraserClicked() {
             Toast.makeText(getApplicationContext(),"eraser is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnClearClicked() {
             Toast.makeText(getApplicationContext(),"clear screen is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override

         }

         @Override
         public void OnUndoClicked() {
             Toast.makeText(getApplicationContext(),"undo button is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnRedoclicked() {
             Toast.makeText(getApplicationContext(),"redo button is clicked.",Toast.LENGTH_SHORT).show();
         }

         @Override
         public void OnSaveClicked(Bitmap bitmap) {
