Buton Ekleme,sayfa değiştirme

11.02.2016 - 10:46


public class HomeFragment extends Fragment {
	
	public HomeFragment(){}
	
	@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
 
        View rootView = inflater.inflate(R.layout.fragment_home, container, false);
         
        return rootView;
    }
}

Buna buton eklemek istiyorum başka bir sayfaya geçiş için ama naptıysam olmuyor.

public class HomeFragment extends Fragment {
	
	Button button1;
	public HomeFragment(){}
	
	@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
 
        View rootView = inflater.inflate(R.layout.fragment_home, container, false);
         
        final Context context = this;
        button1 = (Button) findViewById(R.id.imageButton1);
        button1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent(context, Bilimsel.class);
                startActivity(intent);
            }
        });
        return rootView;
    }

	private Button findViewById(int imagebutton1) {
		// TODO Auto-generated method stub
		return null;
	}
}

final Context context = this;

kısmı hata veriyor.

public class HomeFragment extends Fragment {
	
	Button button1;
	
	@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
 
        View rootView = inflater.inflate(R.layout.fragment_home, container, false);
         
        button1 = (Button) rootView.findViewById(R.id.imageButton1);
        button1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent(getActivity(), Bilimsel.class);
                startActivity(intent);
            }
        });
        return rootView;
    }
}

Bu şekilde çalışması lazım.

Fragment'i extend ettiğinde import kısmı böyle değil mi? import android.support.v4.app.Fragment;

Ali Koparan

android.support.v4.app.Fragment; yaptığımda main activity de hata veriyor * Diplaying fragment view for selected nav drawer list item * */ private void displayView(int position) { // update the main content by replacing fragments Fragment fragment = null; switch (position) { case 0: fragment = new HomeFragment(); break;

final Context context = this; bu satırı kullanmadan, bu şekilde yapabilirsin.

button1.setOnClickListener(new View.OnClickListener(){
    @Override
    public void onClick(View v){
        Intent intent = new Intent(getActivity(),Bilimsel.class);
        getActivity().startActivity(intent);
    }
});
