Question

我正在尝试构建一个由组合在一起的几个控件组成的窗口小部件。这是小部件：

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;
}
}

这里是小部件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>

在我的主视图中，我只是这样使用它：

 <com.proflite.VarioView

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

我的问题是它在模拟器（或真实设备）中运行时工作正常，但是当我尝试在Eclipse中使用图形编辑器时，它会在控件上绘制一个灰色框并给我这个：

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

额外信息，我检查0x7F030001是否已映射到R.layout.vario，错误来自此行：li.inflate(R.layout.vario, this, true);。另外，如果我将其更改为li.inflate(R.layout.vario, this);，它不会给出错误，但控件只显示＆＃34;空白＆＃34;，不会在editmode中呈现（在实际运行时仍然有效）

我真的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模拟器中重新运行它们。

由于

**注意**错误来自放置控件的布局。如果我对控件本身进行图形编辑，它实际上会成功渲染。

嗯，我觉得很傻。重新启动Eclipse后，一切正常。

复合视图无法在Eclipse中以编辑模式呈现
