Imageviewpageadapter cannot be Applied error

Question

Can anyone help me with this error? It occurs when executing a setarView method. Follow the code:

package ufc.es.com.br.doesempre.modelo;

import android.app.Fragment;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;

        super.onViewCreated(v, bd);
        setarView();
        setarTab();
        clicBotaoCirculado();
    }

        public View onCreatedView(LayoutInflater infl, ViewGroup cont, Bundle savedInstanceState) {

    }

    }

    private void setarBotao(Button btn, String txt, int altura, int largura){
        btn.setHeight(altura);
        btn.setWidth(largura);
        btn.setText(txt);
    }

}

Returns the following error:

Fala Rico,

Probably the problem is in your Viewpager statement.

Do the following, declare a View:

private View rootView;

Now, change your own:

public View onCreatedView(LayoutInflater infl, ViewGroup cont, Bundle savedInstanceState) {
     return infl.inflate(R.layout.fragmento_principal, cont, false);
}

for

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

     rootView = inflater.inflate(R.layout.fragmento_principal, container, false);

     return rootView;
}

Now, when declaring the view pager, change this:

viewPager = (ViewPager) viewPager.findViewById(R.id.viewImageFragMain);

That’s why:

viewPager = (ViewPager) rootView.findViewById(R.id.viewImageFragMain);

Hugs.
