Change colour of selected items

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) {
// TODO Auto-generated method stub
}
}

How do you create a dropdown answer in android?

I'm looking for something similar to a drop down menu but when you click on it a block of text drops instead of a list of clickable items. Then you should be able to click to close it again when finished. My app is an informational app so, I want to make a list of several of these within a glossary in my app.
Any ideas??

you should use Spinner in android:
Here is the example :
Spinner mSipnner = (Spinner)findViewById(R.id.spin_beneficiary_targetcode);
List<String> categories2 = new ArrayList<String>();
categories2.add("Choose code");
categories2.add("001");
categories2.add("002");
categories2.add("003");
categories2.add("004");
categories2.add("005");
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories2);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
////Spinner item selected
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// On selecting a spinner item
String targetCode_item = parent.getItemAtPosition(position).toString();
// Showing selected spinner item
//Toast.makeText(parent.getContext(), "Selected: " + category_item, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
// attaching data adapter to spinner
mSpinner.setAdapter(dataAdapter);

show initial value on spinner other than first value in adapter?

i have to display a spinner ,it is getting its content from adapter at run time . when spinner appear on screen Select a value should appear on it instead of first value in adapter.Please help

If you want a particular item in your collection to be selected have a look at:
Spinner.setSelection(int position)

Then You have to add that text at first position in you string array.
Spinner rangeSpinner = (Spinner)findViewById(R.id.rangeSpinner);
String[] items = new String[] {"Select Product","Bread","Milk"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.custom_spinner_textview_layout, items);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
rangeSpinner.setAdapter(adapter);
custom_spinner_textview_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/spinnerTarget"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18.0sp"
android:textColor="#color/grey_text"
android:gravity="left"/>

**Just try It fri...**
1.String[] _Purchesedlistarray = { "Required", "purchased" };
2.ArrayAdapter Purchesedadapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, _Purchesedlistarray);
Purchesedadapter
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
_PurchesedSpinner.setAdapter(Purchesedadapter);

.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {

Appsconstent._Purchesed = parent.getItemAtPosition(
position).toString();
System.out.println("the Value is--------------->"
+ Appsconstent._Purchesed);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
