Olá pessoal, tenho um PagerAdapter, e na sua ActionBar eu coloquei um botão de "Salvar" ai quando o usuário clicasse eu pegaria apenas a informação de um TextView. Mais quando faço...
public boolean onOptionsItemSelected(MenuItem item) {
if (item.toString().equals("Salvar")) {
AguaFragment af = (AguaFragment) getSupportFragmentManager().findFragmentById(R.id.frag_1);
//Log.i("teste", "sera ?" + af.getString(R.id.tv_ml));
//Log.i("teste", "sera ???" + af.getResources().getString(R.id.tv_ml));
//View v = af.getView(); //.findViewById(R.id.tv_ml);
//Log.i("teste", "sera ????" + af.toString());
//Log.i("teste", "sera ????" + tv.getText().toString());
Log.i("teste", "sera ??" + af.getTipo());
}
return true;
}
Da um NullPointer... o af está vindo nulo...
Meu Fragment está assim...
public final class AguaFragment extends Fragment {
private static final String KEY_CONTENT = "TestFragment:Content";
public static AguaFragment newInstance(String content) {
AguaFragment fragment = new AguaFragment();
fragment.mContent = content;
return fragment;
}
private String mContent = "???";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if ((savedInstanceState != null) && savedInstanceState.containsKey(KEY_CONTENT)) {
mContent = savedInstanceState.getString(KEY_CONTENT);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.consumir_agua_fragment,container, false);
TextView tv_ml = (TextView) view.findViewById(R.id.tv_ml);
tv_ml.setText(mContent);
return view;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString(KEY_CONTENT, mContent);
}
public String getTipo(){
View view = getView();
if(view != null){
TextView tv = (TextView) view.findViewById(R.id.tv_ml);
return tv.getText().toString();
}
return "não";
}
Minha duvida e... porque está vindo null ? estou usando o PagerIndicador do Jake.
O Log é esse...
