android - 操作栏按钮未显示在 searchview android 中

Question

我的操作栏上有一个搜索 View 和一个按钮，但该按钮仅在横向模式下显示，但我尝试过它不会在纵向模式下显示。

横向模式

人像模式

这是我的 menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item  
     android:id="@+id/menu_item_search"
     android:title="Search"
     android:showAsAction="ifRoom"
     android:icon="@android:drawable/ic_menu_search" 
     android:actionViewClass="android.widget.SearchView" />
<item 
     android:id="@+id/submit"
     android:title="submit"
     android:showAsAction="always" /> 
</menu>

这是我的主要 Activity

public class Myclass extends Activity implements OnQueryTextListener,OnItemClickListener {
GroupAdapter grpAdapter;
public static ArrayList<GroupsModel> arrayOfList;
public static ListView listView;
public static String base_url = "myurl";
private SeekBar volumeControl = null;
private TextView year;
private int progressChanged = 0;
private Menu menu_data;
MenuItem submitBtn;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.two);
    ActionBar actionBar = getActionBar();
    //actionBar.setDisplayHomeAsUpEnabled(true);
    actionBar.setDisplayShowTitleEnabled(false);
    actionBar.setHomeButtonEnabled(false);
    actionBar.setDisplayShowHomeEnabled(false);
    volumeControl = (SeekBar) findViewById(R.id.volume_bar);
    year = (TextView)findViewById(R.id.year_level);
    volumeControl.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
            progressChanged = progress;
            year.setText(Integer.toString(progressChanged+7));
        }
        public void onStartTrackingTouch(SeekBar seekBar) {

        }
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });
    arrayOfList = new ArrayList<GroupsModel>();
    listView = (ListView) findViewById(R.id.group_listview);
    listView.setOnItemClickListener(this);
    listView.setTextFilterEnabled(true);

    new ProgressTask(two.this).execute();

}

    final boolean isChecked = GroupAdapter.items.get(position).getChecked();
    if(isChecked==false){
        GroupAdapter.items.get(position).setChecked(!isChecked);

    }
    else{
        GroupAdapter.items.get(position).setChecked(isChecked);
        grpAdapter.notifyDataSetChanged();
    }
}   }

请帮帮我。

如果您不关心 SearchView 在开始时折叠，请尝试像这样配置 SearchView:

 android:showAsAction="collapseActionView|ifRoom"

这应该使操作栏同时显示 SearchView 和您的 Button。另外，SearchView 在扩展时只会占用左侧的剩余空间。
