如何在EditMode中充气布局？

Question

我有一个简单的自定义视图，它只是扩展LinearLayout并使用简单的XML布局：

<?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>

以及Java代码：

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);
        }
    }

}

我希望我的自定义视图将在Eclipse编辑器中显示为默认布局(R.layout.my_custom_view)。但它不能膨胀并显示例外：

有办法在EditMode中膨胀默认布局吗？
