复合视图无法在编辑模式下在Eclipse中渲染

Question

我试图构建一个由分组在一起的几个控件组成的小部件。这里的小部件：

public class VarioView extends RelativeLayout { 

private int value; 
private ImageView m_circle; 
private TextView m_varioText; 
private TextView m_units; 
public VarioView(Context context) 
{ 
    this(context,null); 
} 
public VarioView(Context context, AttributeSet attr) 
{ 
    this(context,attr, 0); 
} 
public VarioView(Context context, AttributeSet attr, int defStyle) 
{ 
    super(context, attr, defStyle); 
    //View.inflate(context, R.layout.vario, this); 
    LayoutInflater li = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    li.inflate(R.layout.vario, this, true); 

    m_circle = (ImageView)this.findViewById(R.id.VarioCircle); 
    m_varioText = (TextView)this.findViewById(R.id.VarioText); 

    //m_circle.setColorFilter(Color.BLUE); 
} 
public int getValue() { 
    return value; 
} 
public void setValue(int value) { 
    m_varioText.setText(Integer.valueOf(value).toString()); 
    this.value = value; 
} 
} 

这里的小部件XML

<merge xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
> 

<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <ImageView 
     android:id="@+id/VarioCircle" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_centerInParent="true" 
     android:contentDescription="Vario Circle" 
     android:src="@drawable/circle3" /> 

    <TextView 
     android:id="@+id/VarioText" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerHorizontal="true" 
     android:layout_centerVertical="true" 
     android:text="200" 
     android:textColor="#FF0000" 
     android:textSize="60sp" 
     android:textStyle="bold" 
     android:typeface="monospace" /> 

    <TextView 
     android:id="@+id/VarioUnits" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_below="@id/VarioText" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="100dp" 
     android:text="fpm" 
     android:textSize="20sp" /> 
</RelativeLayout> 

</merge> 

这里的圆形：

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="oval" 
    android:useLevel="false" 
    android:color="#FF0000" > 

    <size 
    android:height="200dip" 
    android:width="200dip" /> 

    <stroke 
    android:width="10dp" 
    android:color="#FF0000" /> 

</shape> 

而且在我的主要观点我只是用这样的：

<com.proflite.VarioView 

     android:layout_width="match_parent" 
    android:layout_height="match_parent" 
/> 

我的问题是它的工作原理很好，当我在模拟器（或真实设备）运行它，但是当我尝试去图形编辑器在Eclipse中它绘制一个灰色的框控件上并给了我这样的：

The following classes could not be instantiated: 
- com.proflite.VarioView (Open Class, Show Error Log) 
See the Error Log (Window > Show View) for more details. 
Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

    at android.view.LayoutInflater.inflate(LayoutInflater.java:372) 

额外的信息，我检查0x7F030001映射到R.layout.vario并且错误来自此行：li.inflate(R.layout.vario, this, true);。此外，如果我将它更改为li.inflate(R.layout.vario, this);它不会给出错误，但控件只显示“空白”，不会在editmode中呈现（实际运行时仍然有效）。

我真的很希望能够在编辑器中可视化布局，因为需要很长时间才能进行小的布局更改并在仿真器中重新运行它们。

谢谢

**注意**错误来自放置控件的布局。如果我在控件本身上进行图形编辑，它实际上会呈现成功。

嗯，我觉得很蠢。我重新启动Eclipse后一切正常。
