Fade-In TextView

Say hi to Fade-In TextView! A custom TextView library which makes every character appear with a smooth alpha animation.

The Fade-In TextView library inherits its properties directly from the native TextView class, which means that all the native TextView methods are supported. There are practically no limitations including multiline support. The library also has some of its own methods and attributes which offer full control over the View.

  // setting a listener for tracking events (optional)

            @Override
            public void onTextStart() {
                Toast.makeText(getBaseContext(), "onTextStart() fired!", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onTextFinish() {
                Toast.makeText(getBaseContext(), "onTextFinish() fired!", Toast.LENGTH_SHORT).show();
            }
        });
  
  textView.setLetterDuration(250); // sets letter duration programmatically
  textView.setText(); // sets the text with animation (Read "KNOWN BUGS" if it doesn't give desired results)
