I have a problem with saving spinner items to shared preferences. By problem I mean I really don't know how to do it. It would be nice if someone could actually explain it to me if someone knows.Thanks in advance :)
so I have set my button 1 to open a dialog with spinner and in spinner i have 3 items (declared in strings.xml). I should use shared preferences to set spinner to item 1 :"-" by default, and if user selects item 2 "lang1" or "lang2" it should be saved in app. So that when i open app next time its on "lang1" or "lang2" depends on selection.
Everything else is working fine.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
SharedPreferences sharedpreferences;
public static final String mypreference = "mypref";
int spinnerPosition;
public Button btnTrans, btnSelect,btnInput,btnCheck;
public TextView tv_title, tv_message;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnSelect= (Button) findViewById(R.id.btnLanguage);
btnInput = (Button) findViewById(R.id.btnInput);
btnTrans = (Button) findViewById(R.id.btnTranslate);
btnTrans.setOnClickListener((View.OnClickListener) this);
btnInput.setOnClickListener(this);
btnSelect.setOnClickListener(this);
Spinner lang_spinner = (Spinner) findViewById(R.id.lang_spinner);
}
public void onClick(View v)
{
int id=v.getId();
switch (id){
case R.id.btnLanguage:
AlertDialog.Builder mBuilder = new AlertDialog.Builder(MainActivity.this);
View mView = getLayoutInflater().inflate(R.layout.language_dialog, null);
mBuilder.setTitle("select language");
final Spinner mSpinner = (Spinner) mView.findViewById(R.id.lang_spinner);
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,
android.R.layout.simple_spinner_item, getResources().getStringArray(R.array.lang_array));
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(adapter);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
SharedPreferences.Editor editor = sharedpreferences.edit();
//SELECTING LANGUAGE switch case (translate btn)-
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {
Object item = adapterView.getItemAtPosition(position);
if (item != null) {
switch (position) {
case 0:
item = "-";
btnTrans.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), R.string.nista, Toast.LENGTH_LONG).show();
}
});
break;
case 1:
item = "lang1";
btnTrans.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), R.string.hrvatski, Toast.LENGTH_LONG).show();
}
});
break;
case 2:
item = "lang2";
btnTrans.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), R.string.english, Toast.LENGTH_LONG).show();
}
});
break;
}
}
//on selected save
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
//nothing selected "-"
}
});
