Her iki parçada da bir düğme bulunan 2 parçam var. Düğmeye bastığımda yeni bir Aktivite başlatmak istiyorum. Ama işe alamıyorum.
Aldığım hata: HATA burada: Tür uyuşmazlığı: mFragmentFavorite'den Fragment'a dönüştürülemiyor
Neyi yanlış yapıyorum?
MyFragmentPagerAdapter
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class MyFragmentPagerAdapter extends FragmentPagerAdapter{
final int PAGE_COUNT = 3;
/** Constructor of the class */
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
/** This method will be invoked when a page is requested to create */
@Override
public Fragment getItem(int arg0) {
switch(arg0){
case 0:
return new FavoriteActivity();
//ERROR: Type mismatch: cannot convert from FavoriteActivity to Fragment
case 1:
return new SettingsActivity();
default:
return null;
}
}
/** Returns the number of pages */
@Override
public int getCount() {
return PAGE_COUNT;
}
}
Favori aktivite
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
public class FavoriteActivity extends Activity{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.main_favorite, container, false);
OnClickListener listnr=new OnClickListener() {
@Override
public void onClick(View v) {
Intent i= new Intent("aFavorite");
startActivity(i);
}
};
Button btn =(Button) v.findViewById(R.id.mainFavorite);
btn.setOnClickListener(listnr);
return v;
}
}
FavoriteActivity parçaları genişletirse, hata gider ancak daha sonra konumunda bir hata alıyorum findViewById(R.id.mainFavorite);
ve hata
FindViewById (int) yöntemi, FavoriteActivity türü için tanımsızdır
DÜZENLE:
Etkinliği başlatmak için parçadaki düğmeye bastığımda uygulama çöküyor, bu benim logcat'im
