我目前正在为ActionBar(ActionBarCompat)工作,我需要一些关于actionbar的澄清.
我正在使用像这样的微调器布局,
<Spinner
android:id="@+id/SpinnerList"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
我的代码,
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);
}
}
它在我的android galaxy ace中显示正常的微调器.我需要输出如下所示,
是那个位置android 2.3.请给出建议.
谢谢.
解决方法
试试这个代码.
在menu / main.xml中：
在menu / main.xml中：
<item
android:id="@+id/menu_spinner1"
android:showAsAction="always"
android:orderInCategory="1"
android:actionViewClass="android.widget.Spinner" >
在活动中：
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;
}
