my idea is to have a text field where I can input a name manually.
Additionally I do have a list of names. If there is at east 1 name in that list an icon should appear on the right of the EditText in order to open a Spinner to give a selection.
If no item is selected the EditText stays the same and if an item has been selected the EditText will have that item.
I'mworking with visibilities so far - but my problem is that the onNothingSelected seems not to get fired at all.
public class MainActivity extends ActionBarActivity {
private Spinner spinner;
private EditText text2;
private ImageButton button2;
private String spinner_value = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
spinner = (Spinner)findViewById(R.id.spinner);
String[] str = {"","good", "dislike", "like", "hate", "moderate"};
spinner.setPrompt("Set Text");
ArrayAdapter<String> list = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, str);
spinner.setAdapter(list);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
TextView tv = (TextView)arg1;
spinner_value = tv.getText().toString();
if(spinner_value.length() == 0)
{
spinner_value = "Nothing";
}
Toast.makeText(getApplicationContext(), spinner_value, Toast.LENGTH_SHORT).show();
spinner = (Spinner) findViewById(R.id.spinner);
text2 = (EditText) findViewById(R.id.editText);
button2 = (ImageButton) findViewById(R.id.imageButton);
text2.setVisibility(View.VISIBLE);
button2.setVisibility(View.VISIBLE);
spinner.setVisibility(View.INVISIBLE);
String myStr = spinner.getSelectedItem().toString();
text2.setText(myStr);
text2.requestFocus();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
Toast.makeText(getApplicationContext(), "NothingSelected", Toast.LENGTH_SHORT).show();
spinner = (Spinner) findViewById(R.id.spinner);
text2 = (EditText) findViewById(R.id.editText);
button2 = (ImageButton) findViewById(R.id.imageButton);
text2.setVisibility(View.VISIBLE);
button2.setVisibility(View.VISIBLE);
spinner.setVisibility(View.INVISIBLE);
text2.requestFocus();
}
});
}
}
By default, the item at index 0 is selected when you spinner is created. So, even though the user doesn't actually do anything, the first item is selected. You can see this happen by setting a breakpoint (or some other notification) in onItemSelected() and seeing it get triggered on startup without the user doing anything.
For the onNothingSelected() callback to get triggered, whatever item is selected has to disappear.

I made a listview and a spinner with 3 options. I want that spinner to connect with Listview on other intent.
The spinner is on a Edit page so whenever I click on 1 item on the list I get to the edit page.
I want the first option on the spinner to make the selected item on the list green the second will make it yellow and then third will make it red. How do I do it?
public class EditList extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
Spinner spinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit_list);
final Button button=(Button)findViewById(R.id.save);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(EditList.this,Vans.class);
startActivity(intent);
}
});
// Spinner element
spinner = (Spinner) findViewById(R.id.spinner);
// Spinner click listener
spinner.setOnItemSelectedListener(EditList.this);
// Spinner Drop down elements
List<String> categories = new ArrayList<>();
categories.add("רכב עובד");
categories.add("יש תקלה");
categories.add("רכב במוסך");
// Creating adapter for spinner
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories);
// Drop down layout style - list view with radio button
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
spinner.setAdapter(dataAdapter);
}
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// On selecting a spinner item
String work = parent.getItemAtPosition(position).toString();
if (position==0){
View listViewChildAt = Vans.listView.getChildAt(position);
listViewChildAt.setBackgroundColor(Color.GREEN);
}
Vans.listView.setBackgroundColor(position);
spinner.setSelection(position);
String takala = parent.getItemAtPosition(position).toString();
if (position==1){
View listViewChildAt = Vans.listView.getChildAt(position);
listViewChildAt.setBackgroundColor(Color.YELLOW);
}
String garage = parent.getItemAtPosition(position).toString();
if (position==2){
View listViewChildAt = Vans.listView.getChildAt(position);
listViewChildAt.setBackgroundColor(Color.RED);
}
}
public void onNothingSelected(AdapterView<?> arg0) {

I am trying to make app with one text view, one button and one spinner. I make button work showing random values from string array, but i have a lot different string arrays(list1, list2 etc). Now my question is when change spinner position, how to get button get another string array(from spinner) and show it to textview.
How to pass value from spinner when something is selected in spinner to button.
Any help is appreciated.
Here is my code:
public class MainActivity extends Activity implements AdapterView.OnItemSelectedListener {
Button btn;
public String[] myString,myString1;
public static final Random rgenerator = new Random();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//textview
final TextView tv = (TextView) findViewById(R.id.textureView);
final Resources res = getResources();
//string
myString = res.getStringArray(R.array.World_War_I);
myString1 = res.getStringArray(R.array.World_War_II);
//button
btn = (Button) findViewById(R.id.buttonxx);
btn.setOnClickListener(new View.OnClickListener(){
public void onClick (View v){
//i am missing code here, spinner position, and pass spinner position to if statement.
if (==0){
myString = res.getStringArray(R.array.list1);
String q = myString[rgenerator.nextInt(myString.length)];
tv.setText(q);
}
if (==1){
myString1 = res.getStringArray(R.array.list2);
String q1 = myString1[rgenerator.nextInt(myString.length)];
tv.setText(q1);
}
}
});
//drop list
Spinner spinner = (Spinner) findViewById(R.id.spinnerrrr);
spinner.setOnItemSelectedListener(this);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.kategorije, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
}
// when some cat selected
public void onItemSelected(AdapterView<?> parent, View view,
final int pos, long id) {
// An item was selected. You can retrieve the selected item using
parent.getItemAtPosition(pos);
parent.setSelection(0);
parent.getSelectedItemPosition();
}
public void onNothingSelected(AdapterView<?> parent) {
// Another interface callback
}
Use this
// when some cat selected
public void onItemSelected(AdapterView<?> parent, View view,
final int pos, long id) {
// An item was selected. You can retrieve the selected item using
btn.setTag(pos+""); // Passing as string
parent.getItemAtPosition(pos);
parent.setSelection(0);
parent.getSelectedItemPosition();
}
and then
btn.setOnClickListener(new View.OnClickListener(){
public void onClick (View v){
//i am missing code here, spinner position, and pass spinner position to if statement.
int index = Integer.parseInt(btn.getTag().toString());
if (index==0){
myString = res.getStringArray(R.array.list1);
String q = myString[rgenerator.nextInt(myString.length)];
tv.setText(q);
}
if (index==1){
myString1 = res.getStringArray(R.array.list2);
String q1 = myString1[rgenerator.nextInt(myString.length)];
tv.setText(q1);
}
}
});

Please, help me ! :)
Update the adapter by removing the selected data from the list. Use Handler concept to update adapter.
Set a new adapter on the Spinner via setAdapter(). Or, if it is an ArrayAdapter, use add(), insert(), and remove() to modify the data. Or, if it is a CursorAdapter, requery() it to get fresh data.
