The problem is the following, in the activity I have a textView and a spinner what I'm looking for is that when you select an option in spinner the value of textView change.
This is the code
public class longitud extends AppCompatActivity {
TextView tex1 , tex2 , tex3 ;
EditText valor ;
private TypedArray textview;
private TextView textView;
private String[] listOfObjects;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_longitud);
tex1 = (TextView)findViewById(R.id.tex1longitud);
tex2 = (TextView)findViewById(R.id.tex2longitud);
tex3 = (TextView)findViewById(R.id.tex3longitud);
valor = (EditText)findViewById(R.id.edit1longitud);
listOfObjects = getResources().getStringArray(R.array.object_array3);
textview = getResources().obtainTypedArray(R.array.object_array_3);
textView = (TextView) findViewById(R.id.textView1logitud);
Button btconvertir = (Button)findViewById(R.id.botonlongitud1);
final Spinner spinner = (Spinner)findViewById(R.id.spinnerlongitud);
ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_spinner_item, listOfObjects);
spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerAdapter);
btconvertir.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (spinner.getSelectedItemPosition()){
case 0 :
/**
* case EMPTY TO SPINNER TITTLE
* **/
break;
case 1:
/** cm to ft
*
* formula d(ft)=d(cm)/30.42
**/
if (!(valor.getText().toString()).isEmpty()){
double valor_1= Double.parseDouble(valor.getText().toString());
tex1.setText("d(ft)=d(cm)/30.42");
tex2.setText("d(ft)="+ valor_1 +"cm/30.42");
double resu = valor_1 / 30.42; /** centimeroFtConstante valor de 30.42 **/
tex3.setText("d(ft)="+ valor_1 +"cm");
}
break;
case 2 :
/** cm to pulg
*
* formula d(")=d(cm)/2.54 */
if (!(valor.getText().toString()).isEmpty()){
double valor_1= Double.parseDouble(valor.getText().toString());
tex1.setText("d(inc)=d(cm)/2.54 ");
tex2.setText("d(inc)="+valor_1+"cm/2.54 ");
double resu1 = valor_1/2.54;
tex3.setText("d(inc)="+resu1);
}
break;
case 3 :
/**
* cm to mm
*
* formula d(mm)=d(cm)*10

if (!(valor.getText().toString()).isEmpty()){
double valor_1= Double.parseDouble(valor.getText().toString());
tex1.setText("d(mm)=d(cm)*10");
tex2.setText("d(mm)="+valor_1+"cm*10");
double resu1 = valor_1*10;
tex3.setText("d(mm)="+resu1);
}
break;
case 4:
/**
* ft to cm
*
* formula d(cm)=d(ft)*30.48
* */
if (!(valor.getText().toString()).isEmpty()){
double valor_1= Double.parseDouble(valor.getText().toString());
tex1.setText("d(cm)=d(ft)*30.48");
tex2.setText("d(cm)="+valor_1+"ft*30.48");
double resu1 = valor_1 * 30.48;
tex3.setText("d(cm)="+resu1);
}
break;
case 5 :
/**
* feet to mm
*
* formula d(mm)=d(ft)*304.8

if (!(valor.getText().toString()).isEmpty()){

}
break;
case 6:
/**
* feet to inches
*
* formula d(inch)=d(ft)*12
* */
if (!(valor.getText().toString()).isEmpty()){
double valor_1= Double.parseDouble(valor.getText().toString());
tex1.setText("d(inch)=d(ft)*12");
tex2.setText("d(inch)="+valor_1+"ft*12");
double resu1 = valor_1*12;
tex3.setText("d(inch)="+resu1);
}
break;
case 7 :
if (!(valor.getText().toString()).isEmpty()){
double valor_1= Double.parseDouble(valor.getText().toString());
}
break;
default:
break;
}
}
});
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
textView.setText(textview.getResourceId(spinner.getSelectedItemPosition(), -1));
}
@Override
