如何在EditMode中擴充佈局？

我剛剛擴展的LinearLayout和使用簡單的XML佈局一個簡單的自定義視圖：如何在EditMode中擴充佈局？

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center_horizontal" 
    android:orientation="horizontal" > 

    <ImageView 
     android:id="@+id/iv1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:src="@drawable/ic_image1" /> 

    <TextView 
     android:id="@+id/tv1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/text1" 
     android:textAppearance="?android:attr/textAppearanceLarge" /> 

    <TextView 
     android:id="@+id/tv2" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/text2" 
     android:textAppearance="?android:attr/textAppearanceLarge" /> 


</LinearLayout>

而Java代碼：

public class MyCustomView extends LinearLayout { 

    public MyCustomView(Context context) { 
     super(context); 
     init(context); 
    } 

    public MyCustomView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     init(context); 
    } 

    @SuppressLint("NewApi") 
    public MyCustomView(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 
     init(context); 
    } 

    private void init(Context context) { 
     if (isInEditMode()) { 
      // How to inflate R.layout.my_custom_view here? 
     } else { 
      LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      inflater.inflate(R.layout.my_custom_view, this, true); 
     } 
    } 

}

我想，我的自定義視圖，在Eclipse佈局編輯器顯示爲默認佈局（R.layout.my_custom_view）。但它不能膨脹，並顯示異常：

有沒有辦法在EditMode中膨脹默認佈局？

變化

if(isInEditMode())

要

if(!isInEditMode())

當我這樣做，我得到異常資源$ NotFoundException像描述。 – BArtWell

評論第一個構造函數並嘗試。 – R9J

仍然顯示NotFoundException。 – BArtWell
