blocks|key|4120011|text|你说的id是什么意思。可以使用ArrayAdapter填充微调器。选择item时，只需从适配器获取元素并保存所需的数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4120012|Spinner+spinner+=+(Spinner)+findViewById(R.id.spinner);
ArrayAdapter<MyObject>+adapter+=+...+//+initialize+the+adapter
adapter.setDropDownViewResource(android.R.layout.some_view);
spinner.setAdapter(adapter);|code-block|syntax|javascript|4120013|以及当选择项时|4120014|public+void+onItemSelected(AdapterView<?>+parent,+View+view,+int+pos,+long+id)+{
++++MyObject+selected+=+parent.getItemAtPosition(pos);
++++//+save+any+data+relevant+with+selected+item+++
}|4120015|如果您将数据存储在db中，则可以使用CursorAdapter和onItemSelected从光标中获取所选项目的id。|4120016|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

What do you mean by id. You can use ArrayAdapter to populate the Spinner. When item is selected just get the element from the adapter and save the data you want.

<pre><code>Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter&lt;MyObject&gt; adapter = ... // initialize the adapter
adapter.setDropDownViewResource(android.R.layout.some_view);
spinner.setAdapter(adapter);
</code></pre>

and when item is selected 

<pre><code>public void onItemSelected(AdapterView&lt;?&gt; parent, View view, int pos, long id) {
 MyObject selected = parent.getItemAtPosition(pos);
 // save any data relevant with selected item 
}
</code></pre>

If you are storing your data in db you can use CursorAdapter and in onItemSelected to fetch the selected item id from the cursor.

blocks|key|4120095|text|我不认为您可以将任意的ID附加到文本数组资源的元素上，如果您正在使用的话。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4120096|我认为附加此类ID的最简单方法是硬编码(如果使用静态文本资源)或从(数组中的字符串位置)->(主键)动态构建映射(如果在运行时获得字符串)。|4120097|编辑:另一方面，Mojo+Risin有一个要点-你应该检查一下CursorAdapter+API是否已经为你做了你需要的事情。|4120098|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I don't think you can attach an arbitrary ID to elements of a text array resource, if that's what you're using.

I think the simplest way to attach such an ID would be to either hard-code (if you're using a static text resource) or dynamically build (if you get the strings at runtime) a mapping from (String position in array)->(primary key).

EDIT: On the other hand, Mojo Risin has a point - you should check to see if the CursorAdapter API already does what you need for you.

blocks|key|2369325|text|我认为最好的解决方案是再添加一个微调器，并用it填充它，但使它的可见性消失。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2369326|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I think The best solution is to add one more spinner and fill it with the ids but make the visibility of it to gone

blocks|key|426559|text|创建一个类StringWithTag并使用来代替列表中的字符串名称，如下所示:-|type|unstyled|depth|inlineStyleRanges|entityRanges|data|426560|public+class+StringWithTag+{

++++public+StringWithTag(String+stringPart,+Object+tagPart)+{

++++}

++++@Override
++++public+String+toString()+{
++++++++return+string;

}|code-block|syntax|javascript|426561|在将项目添加到微调器部分中:-|426562|List<StringWithTag>+list+=+new+ArrayList<StringWithTag>();

ArrayAdapter<StringWithTag>+adap+=+new+ArrayAdapter<StringWithTag>+(this,+android.R.layout.simple_spinner_item,+list);

Create a class StringWithTag and use in place of the string name in the list like so :-

<pre><code>public class StringWithTag {
 public String string;
 public Object tag;

 public StringWithTag(String stringPart, Object tagPart) {
 string = stringPart;
 tag = tagPart;
 }

 @Override
 public String toString() {
 return string;
 }
}
</code></pre>

in the add items to spinner part :-

<pre><code>List&lt;StringWithTag&gt; list = new ArrayList&lt;StringWithTag&gt;();
list.add(new StringWithTag("Oldman", "12345"));
list.add(new StringWithTag("Umpire", "987654"));
list.add(new StringWithTag("Squad", "ABCDEE"));
ArrayAdapter&lt;StringWithTag&gt; adap = new ArrayAdapter&lt;StringWithTag&gt; (this, android.R.layout.simple_spinner_item, list);
....
....
</code></pre>

in the listener :-

<pre><code>public void onItemSelected(AdapterView&lt;?&gt; parant, View v, int pos, long id) {
 StringWithTag s = (StringWithTag) parant.getItemAtPosition(pos);
 Object tag = s.tag;
}
</code></pre>

voila!
 }

Andrew Hi, it's been a long time but it's worth to write.

You can set a tag for each row when you'r inflating spinnerLayout in SpinnerAdapter:

<pre><code>spinnerView = inflater.inflate(spinnerLayout, parent, false);
spinnerView.setTag("Your Tag");
</code></pre>

And then you can get the tag with:

<pre><code>yourSpinner.getSelectedView().getTag();
</code></pre>

I have an array of Strings I'm populating a Spinner object with. However, I'd like to attach an ID to each element of the Spinner, so when the user selects an item, I have its ID to use to save to some other piece of data. How can I do this?

我有一个字符串数组，用来填充一个微调器对象。但是，我想为微调器的每个元素附加一个ID，这样当用户选择一个项目时，我就有了它的ID来保存到其他一些数据中。我该怎么做呢？
