método não estático getActivity ()
Eu fiz o método "showResult" estático, mas tenho problemas com:
"Toast.makeText(`getActivity()`.getApplication(), result2 + "\n" + "Total Amount:=" + totalAmount2 + "€", Toast.LENGTH_LONG).show();"
Como resolver meu problema? Vou compartilhar meu código.
OBRIGADO COM ANTECEDÊNCIA DE TODOS!
Aqui está minha primeira classe Fragment.java
public class MyListFragment extends Fragment implements
android.widget.CompoundButton.OnCheckedChangeListener {
ListView lv;
ArrayList<Planet> planetList;

BirraAdapter biAdapter;
PlanetAdapter.PlanetHolder holder;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_list2, container, false);
Button mButton = (Button) rootView.findViewById(R.id.button);
mButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showResult(v);
}
});
//return inflater.inflate(R.layout.fragment_list2, container, false);
return rootView;
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
lv = (ListView)getView().findViewById(R.id.listview);
displayPlanetList();
}
private void displayPlanetList() {
planetList = new ArrayList<Planet>();
planetList.add(new Planet("Margherita", 6, "€",1));
planetList.add(new Planet("Diavola", 7,"€",2));
planetList.add(new Planet("Bufalina", 5,"€",3));
planetList.add(new Planet("Marinara", 5, "€",4));
planetList.add(new Planet("Viennese", 4, "€", 5));
plAdapter = new PlanetAdapter(planetList, getContext()) {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int pos = lv.getPositionForView(buttonView);
if (pos != ListView.INVALID_POSITION) {
Planet p = planetList.get(pos);
p.setSelected(isChecked);
/*Toast.makeText(

lv.setAdapter(plAdapter);

}
public static void showResult(View v) {

int totalAmount=0;

}
int totale=totalAmount+totalAmount2;
z=String.valueOf(totale);
}
Toast.makeText(getActivity().getApplication(), result2 + "\n" + "Total Amount:=" + totalAmount2 + "€", Toast.LENGTH_LONG).show();
//Toast.makeText(getActivity(), result2 + "\n" + "Total Amount:=" + totalAmount2 + "€", Toast.LENGTH_LONG).show();
