Annotation Type OnTextChanged

@Target(value=METHOD)
 @Retention(value=CLASS)
public @interface OnTextChanged

Bind a method to a TextWatcher on the view for each ID specified.

  @OnTextChanged(R.id.example) void onTextChanged(CharSequence text) {
   Toast.makeText(this, "Text changed: " + text, Toast.LENGTH_SHORT).show();
 }
 

Any number of parameters from onTextChanged may be used on the method.

To bind to methods other than onTextChanged, specify a different callback.

  @OnTextChanged(value = R.id.example, callback = BEFORE_TEXT_CHANGED)
 void onBeforeTextChanged(CharSequence text) {
   Toast.makeText(this, "Before text changed: " + text, Toast.LENGTH_SHORT).show();
 }
