Set text of spinner before item is selected

Question

I have a spinner with three items and I use an XML string-array resource to feed it. When you open an activity the spinner normally shows the first item that\'s in the array lis

Answer 1

To set a default text for the spinner you have to use android:prompt=@string/SelectOne for your spinner Where SelectOne is defined in your string.xml .

Example :

<Spinner android:id="@+id/spinnerTest"  
 android:layout_marginLeft="50px"
 android:layout_width="fill_parent"                  
 android:drawSelectorOnTop="true"
 android:layout_marginTop="5dip"
 android:prompt="@string/SelectOne"
 android:layout_marginRight="30px"
 android:layout_height="35px" 
/> 

Answer 2

You can do that one of two ways.

1) Add "Select One" as the first item in your xml and code your listener to ignore that as a selection.

2) Create a custom adapter to insert it as the first line,

EDIT

In your resources

<string-array name="listarray">
    <item>Select One</item>
    <item>Item One</item>
    <item>Item Two</item>
    <item>Item Three</item>
</string-array>

In your onItemSelected Listener:

spinnername.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
    public void onNothingSelected(AdapterView<?> parent) {
    }
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        if (pos == 0) {
        }else {
            // Your code to process the selection
        }
    }
});
