我的自定义视图，不在横向模式下工作，但在纵向模式下工作

Question

我创建了一个自定义视图，我希望在活动中以横向模式显示它，但是当我从我的代码中将方向设置为横向，或者将模拟器更改为横向（使用CTRL + f11）时，我的视图是没有显示!!并且屏幕是空白的。这是我的代码

output_view.xml：

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/groubbox">

<TextView 
    android:id="@+id/textView_Output"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/firstOutput"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="10dp"
    android:layout_marginLeft="10dp"/>

<Spinner 
    android:id="@+id/spineer_Output"
    android:layout_width="100dp"
    android:layout_height="50dp"
    android:layout_toLeftOf="@id/textView_Output"
    android:layout_centerVertical="true"
    android:layout_marginLeft="10dp"
    android:layout_marginTop="10dp"
    android:layout_marginBottom="10dp"/>

<TextView 
    android:id="@+id/textView_OutputTime"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/outputTime"
    android:layout_toLeftOf="@id/spineer_Output"
    android:layout_centerVertical="true"
    android:layout_marginLeft="10dp"/>

<EditText 
    android:id="@+id/editText_time"
    android:layout_width="80dp"
    android:layout_height="wrap_content"
    android:inputType="text"
    android:layout_toLeftOf="@id/textView_OutputTime"
    android:layout_centerVertical="true"
    android:layout_marginLeft="10dp"/>

Output_View.java：

public class Output_View extends RelativeLayout{

private Context context;
private ActionbarClickedListener actionbarClickedListener;

private LayoutInflater mInflater;
private TextView tv_output, tv_outputTime;
private Spinner sp_output;
private EditText et_time;

public Output_View(Context context) {
    super(context);
    this.context = context;
    init();
}

public Output_View(final Context context, AttributeSet attrs) {
    super(context, attrs);
    this.context = context;
    init();
}

public Output_View(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    this.context = context;
    init();
}

public void init() {
    mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    RelativeLayout barView = (RelativeLayout) mInflater.inflate(R.layout.output_view, null);
    addView(barView);

    tv_output = (TextView) findViewById(R.id.textView_Output);
    tv_outputTime = (TextView) findViewById(R.id.textView_OutputTime);
    et_time = (EditText) findViewById(R.id.editText_time);
    sp_output = (Spinner) findViewById(R.id.spineer_Output);
}


public void setOnItemClickedListener(ActionbarClickedListener actionbarClickedListener) {
    this.actionbarClickedListener = actionbarClickedListener;
}

public interface ActionbarClickedListener {
    public void eventOccured(int id);
}

}

main.xml：

<RelativeLayout
    xmlns:android = "http://schemas.android.com/apk/res/android"
    android:layout_width = "fill_parent"
    android:layout_height = "wrap_content"
android:layout_alignParentLeft  = "true"
android:layout_alignParentTop   = "true" >

<Kazemi.Alireza.scada.Output_View
        android:id = "@+id/actionBar" 
    android:layout_width = "fill_parent"
    android:layout_height = "wrap_content"
    android:layout_marginLeft="10dp"/>

和主要班级：

public class Scada extends Activity
{
    String result;
    String[] param;
    String userUrl = "http://www.hushmandsazan.com/scada/get_user.php?uname=";
    public void onCreate(Bundle bundle)
    {
            super.onCreate(bundle);
            setContentView(R.layout.test);
    }
}
