I hope it will helpful to you.

Try this Code...

Here i store the index and value of selected spinner into SharedPreferences

<pre><code>private SharedPreferences prefs;
private String prefName = "spinn";

final List&lt;String&gt; list=new ArrayList&lt;String&gt;();

list.add("Item 1");
list.add("Item 2");
list.add("Item 3");
list.add("Item 4");
list.add("Item 5");

final Spinner sp1= (Spinner) findViewById(R.id.spinner1);
ArrayAdapter&lt;String&gt; adp1=new ArrayAdapter&lt;String&gt;(this,
 android.R.layout.simple_list_item_1,list);
adp1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp1.setAdapter(adp1);

sp1.setOnItemSelectedListener(new OnItemSelectedListener()
{

 @Override
 public void onItemSelected(AdapterView&lt;?&gt; arg0, View arg1,
 int position, long id) {
 // TODO Auto-generated method stub
 int pos1=position;
 String str1=sp1.getSelectedItem().toString();

 prefs = getSharedPreferences(prefName, MODE_PRIVATE);
 SharedPreferences.Editor editor = prefs.edit();

 //---save the values in the EditText view to preferences---
 editor.putInt("index", pos1);
 editor.putString("value", str1);

 //---saves the values---
 editor.commit();

 }

 @Override
 public void onNothingSelected(AdapterView&lt;?&gt; arg0) {
 // TODO Auto-generated method stub

 }

});
</code></pre>

To get that value into another java file, inside that java file write below code where ever you need it..

<pre><code> prefs = getSharedPreferences(prefName, MODE_PRIVATE);
 int pos=prefs.getInt("index", (Integer) null);
 String value=prefs.getString("value", "");
</code></pre>

Sorry, I posted it wrong. 
Pls try this.

<pre><code>String []data={"item1","item2","item3","item4","item5"};

spinner.setAdapter(adaptador);
spinner.setOnItemSelectedListener(
 new AdapterView.OnItemSelectedListener() {
 public void onItemSelected(AdapterView&lt;?&gt; parent,

 }

 public void onNothingSelected(AdapterView&lt;?&gt; parent) {
 mData.setText("");
 }
});
</code></pre>

blocks|key|981023|text|使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|981024|final+String+text+=+((YourAdapter)+spinner.getAdapter()).getItem(spinner.getSelectedItemPosition());|code-block|syntax|javascript|981025|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Use this:

<pre><code>final String text = ((YourAdapter) spinner.getAdapter()).getItem(spinner.getSelectedItemPosition());
</code></pre>

blocks|key|981027|text|这应该是可行的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|981028|@Override
++++++++public+void+onItemSelected(AdapterView<?>+arg0,+View+arg1,
++++++++++++++++++++++++int+position,+long+id)+{+

This should work: 

<pre><code>@Override
 public void onItemSelected(AdapterView&lt;?&gt; arg0, View arg1,
 int position, long id) { 
 String value = (TextView)view.getText().toString();
 }
</code></pre>

<code>placeSpinner.getSelectedItem().toString();</code>

so I'm using this coding lines to get the text from my <code>spinner</code> and pass it on to another java file. But the application keeps giving me a force close whenever I do this.

How can I resolve this error?

Thank you so much.

Getting text from spinner

placeSpinner.getSelectedItem().toString();所以我使用下面的代码行从我的spinner中获取文本，并将其传递给另一个java文件。但每当我这样做的时候，应用程序都会给我一个强制关闭。如何解决此错误？非常感谢。
