Annotation Type ViewById

@Retention(value=CLASS)
 @Target(value={FIELD,METHOD,PARAMETER})
public @interface ViewById

Use it on View or View subtype fields or method parameters in a view related (ie EActivity, EFragment, EViewGroup, ...) annotated class.

The annotation value should be one of R.id.* fields. If not set, the field or method name will be used as the R.id.* field name.

Your code related to injected views should go in an AfterViews annotated method.

Example :

 @EActivity(R.layout.main)
 public class MyActivity extends Activity {
 
        // Injects R.id.myEditText
        @ViewById
        EditText myEditText;
 
        @ViewById(R.id.myTextView)
        TextView textView;
 
        @ViewById
        void singleInjection(EditText myEditText) {
                // do stuff
        }

        void multiInjection(@ViewById EditText myEditText, @ViewById(R.id.myTextView) TextView textView) {
                // do stuff
        }
 
        @AfterViews
        void updateTextWithDate() {
                myEditText.setText("Date: " + new Date());
        }
 }
