My spinner is returning null, probably at the time of passing to the string there is something wrong and there is an error in these lines :
com.example.thiago.myapplication.Activity_addinf.onCreate(Activity_addinf.java: 128)
Caused by: java.lang.RuntimeException: setOnItemClickListener cannot be used with a spinner.
My code :
public class Activity_addinf extends AppCompatActivity implements IHttpConnection, AdapterView.OnItemSelectedListener {
catliv = (Spinner) findViewById(R.id.catergorialiv);
List<String> list = new ArrayList<String>();
list.add("Romance");
list.add("Direito");
list.add("Didatico");
list.add("Informática");
list.add("Ficção Cientifíca");
list.add("Infantil");
list.add("Drama");
list.add("Contos");
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
catliv.setAdapter(dataAdapter);
btnadd1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// mCatliv = parent.getItemAtPosition(position).toString();
if (mCatliv.equals("Romance")) {
postCatLivro("http://192.168.1.207/api/v2/bookdemo/_table/cad_categorias?fields=id_cat&filter=tx_cat%3Dromance", 2);
