I recommend you check: <a href="http://developer.android.com/resources/tutorials/views/hello-spinner.html">http://developer.android.com/resources/tutorials/views/hello-spinner.html</a>

You should create an ArrayAdapter in your Activity.

From the above link:

<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 Spinner spinner = (Spinner) findViewById(R.id.spinner);
 ArrayAdapter&lt;CharSequence&gt; adapter = ArrayAdapter.createFromResource(
 this, R.array.planets_array, android.R.layout.simple_spinner_item);
 adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
 spinner.setAdapter(adapter);
}
</code></pre>

You can use

<pre><code>spinner.setSelection(adapter.getPosition(value)));
</code></pre>

to set the position.

blocks|key|3463857|text|为回复干杯……|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3463858|我没有做我需要的事情，但我已经设法解决了我的问题，如下所示。|3463859|首先，我在我的activity中创建了一个数组，而不是strings.xml。|3463860|++++String[]+NoCore_Array+=+new+String+[5];

Cheers for reply.....

Didn't do what i needed, but have managed to solve my problem as follows..

First i created an array within my activity, instead of strings.xml.

<pre><code> String[] NoCore_Array = new String [5];
{ 
 NoCore_Array[0] = "1";
 NoCore_Array[1] = "2";
 NoCore_Array[2] = "3";
 NoCore_Array[3] = "4";
 NoCore_Array[4] = "5";

}
</code></pre>

Then i created the spinner using...

<pre><code> Spinner spnNoCore = (Spinner) findViewById(R.id.spinner_nocore);
</code></pre>

Then created the adapter, using above array....

<pre><code> ArrayAdapter NoCoreAdapter = new ArrayAdapter(this, 
 android.R.layout.simple_spinner_item, NoCore_Array);
 spnNoCore.setAdapter(NoCoreAdapter);
</code></pre>

Then set default position of the adapter as follows...

<pre><code> //Set Default Selection
 spnNoCore.setSelection(1);
</code></pre>

Then rest of spinner code for actions...

<pre><code> spnNoCore.setOnItemSelectedListener(new OnItemSelectedListener(){

 public void onItemSelected(AdapterView&lt;?&gt; parent,
 View view, int pos, long id) {

 //Get item from spinner and store in string conductorSize........
 NoCore = parent.getItemAtPosition(pos).toString();

 if (NoCore.equals(NoCore1)) { CoreNo = 1 ; }
 if (NoCore.equals(NoCore2)) { CoreNo = 2 ; }
 if (NoCore.equals(NoCore3)) { CoreNo = 3 ; }
 if (NoCore.equals(NoCore4)) { CoreNo = 4 ; }
 if (NoCore.equals(NoCore5)) { CoreNo = 5 ; }

 }

 public void onNothingSelected(AdapterView parent) {
 // Do nothing.
 }
 });
</code></pre>

Hope this may help other people who are having same problem with
setting default selection on Spinner.

However the layout of the dialog is not as good when done this way,
Radio buttons are missing, just looks like a text selection
with lines dividing the sections.

I have a spinner, that uses an array from strings.xml

if the array has 5 strings (1,2,3,4,5), and i want the spinner to show second
string (2) as default value, is this possible?
I know i can re-arrange the strings order so that first one is 2,
but this doesn't look very good if spinner dialog appears as (2,1,3,4,5).

Or does the array have to be created within my activity programatically
and then use setPostion()?
I have tried this, but get a fault when creating array in activity.
Can anyone please give me an example of how to create array and use
it in spinner()

I have also searched on here for answers but cant seem to find what i need.

Thanks for looking....

我有一个微调控制项，它使用来自strings.xml的数组如果数组有5个字符串(1,2,3,4,5)，我希望微调器将第二个字符串(2)显示为默认值，这可能吗？我知道我可以重新排列字符串的顺序，使第一个是2，但是如果微调器对话框显示为(2,1,3,4,5)，这看起来就不是很好。或者必须在我的activity中以编程方式创...
