@FocusChange

This annotation is intended to be used on methods to receive events defined by android.view.View.OnFocusChangeListener.onFocusChange(View view, boolean hasFocus) when the focus state of a view has changed. The annotation value should be one or several R.id.* fields that refers to a subclass of View. If not set, the method name will be used as the R.id.* field name. The method may have multiple parameters:

• A android.view.View parameter to know which view has targeted this event.
• An boolean parameter to know if the view gain or lost the focus.

Some usage examples of @FocusChange annotation:

@FocusChange(R.id.helloTextView)
void focusChangedOnHelloTextView(View hello, boolean hasFocus) {
	// Something Here
}

@FocusChange
void helloTextViewFocusChanged(View hello) {
	// Something Here
}

@FocusChange({R.id.editText, R.id.helloTextView})
void focusChangedOnSomeTextViews(View hello, boolean hasFocus) {
	// Something Here
}

@FocusChange(R.id.helloTextView)
void focusChangedOnHelloTextView() {
	// Something Here
}
