我有一个扩展View的类Bubble。我需要在我的片段中使用它,布局文件如下所示(请注意我的泡泡视图在此布局中显示):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    android:background="#ffcc33">

    <!-- ***** note that since I am here loading my Bubble class that extends View, that class
         c-tor must take Context AND AttributeSet, otherwise loading this will crash.
         See Bubble c-tor below *****
         -->
    <study.android.bubble.Bubble
        android:id="@+id/bubbleAnimationView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ff1122"
        android:padding="20dp"/>

    <!-- since parent is FrameLayout, this view will be stacked up in z-order -->
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_gravity="right|bottom"
        android:layout_margin="10dp">

        <ImageButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:src="@mipmap/ic_launcher"
            android:background="@null"/>
    </LinearLayout>
</FrameLayout>

我的自定义视图Bubble的构造函数如下所示:

public class Bubble extends View {

    public Bubble(Context context, AttributeSet attributesSet) {
        super(context, attributesSet);
        ...
        ...
    }

    // drawing methods
    ...
    ...
}

当我想从我的片段中实例化它时,比如在onAttach()中,如何将它传递给AttributeSet?

谢谢,
