我正在尝试填充一个内部类视图，但遇到了“错误填充类”问题。我参考了这篇文章，它很有帮助，但我仍然不知道为什么无法使其工作。
这里是代码片段、我的XML和Logcat。
编辑：我还注意到Logcat针对“CupcakeMessageView（Context，AttributeSet）”报告了“没有这样的方法异常”，而我明显有这个方法。
感谢大家！
public class CupcakeMessage extends Activity {
class CupcakeMessageView extends View {
private static final int TEXT_SIZE = 12;
private static final int X_OFFSET = 15;
private Paint mPaint;
public CupcakeMessageView(Context context) {
super(context);
}
public CupcakeMessageView(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
...
}
more class stuff...
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.cupcake_message);
...
}
}
这里是XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<view class="com.cmllc.zcc.CupcakeMessage$CupcakeMessageView"
android:id="@+id/cupcake_message_view"
android:screenOrientation="portrait"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
more views...
