我目前工作动作条（ActionBarCompat）导向的项目，我需要了解的ActionBar一些澄清。

I am currently working ActionBar (ActionBarCompat) oriented project, I Need some Clarification about actionbar.

我使用的微调布局，

<Spinner 
        android:id="@+id/SpinnerList"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

我的code，

My code,

public class MainActivity extends ActionBarActivity implements  OnItemSelectedListener{
    private boolean mAlternateTitle = false;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ActionBar bar = getActionBar();
        bar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);

        Spinner spinner = (Spinner) findViewById(R.id.SpinnerList);
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.locations, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);
        spinner.setOnItemSelectedListener(this);
}
}

据显示在我的Andr​​oid银河王牌正常微调。我需要的输出一样如下， 是那个位置的Andr​​oid 2.3。请给建议。

It is displaying normal spinner in my android galaxy ace. I need output like given below, Is that position android 2.3. Please give suggestion.

感谢。

推荐答案

试试这个code。  在菜单/ main.xml中：

Try this code . In menu/main.xml :

<item
    android:id="@+id/menu_spinner1"
    android:showAsAction="always"
    android:orderInCategory="1"
    android:actionViewClass="android.widget.Spinner" >

在活动：

private MenuItem mSpinnerItem1 = null;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.


    MenuInflater mi=getMenuInflater();
    mi.inflate(R.menu.main, menu);
    mSpinnerItem1 = menu.findItem( R.id.menu_spinner1);
    View view1 = mSpinnerItem1.getActionView();
    if (view1 instanceof Spinner)
    {
        final Spinner spinner = (Spinner) view1;
        spinner.setAdapter(ad1);


        spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

    }

    return true;
}
