Assisted Inject

[Adam Tybor]

Just an FYI, the assisted inject extension works with robo on android.  I wish I new about this one before.  Sure beats all those crazy providers I have been rolling.

Cheers,

Neat! I always assumed that assisted inject used codegen or aop and wouldn't work with android

What are you using it for out of curiosity?

public SpinnerCursorAdapter(Activity context, @Assisted CursorProvider cursorProvider, @Assisted String textColumn) {

 // ...

}

public interface SpinnerCursorAdapterFactory {

        public SpinnerCursorAdapter create(CursorProvider cursorProvider, String textColumn);

    }

I inject this guy into my activity and then when I need a spinner its just

spinner.setAdapter(adapterFactory.create(new CursorProvider() {

  Cursor get() {

    return db.findAllColors();

  }, DatabaseHelper.Columns.Color);

I have a lot of spinners and they are all actually dependent on each other so I built a custom adapter to handle all the query changes and cursor switches asynchronously.
