以下代码有无错误 <?xml version="1.0" encoding="utf-8"?> <com.blog.demo11.DragViewGroup xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:layout_width="70dp" android:layout_height="70dp" android:text="@string/txt_drag" android:gravity="center" android:textColor="#fff" android:background="#6495ED" android:layout_margin="24dp" /> </com.blog.demo11.DragViewGroup> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:id="@+id/backgroundImage" android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/tianzige" /> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:orientation="horizontal"> <ImageView android:id="@+id/image1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/gengzhegou" /> <ImageView android:id="@+id/image2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/pie" android:layout_marginLeft="10dp" /> <ImageView android:id="@+id/image3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/shuwangou" android:layout_marginLeft="10dp" /> </LinearLayout> </RelativeLayout>

代码中没有明显的语法错误,但是需要注意以下几点:
1. `<com.blog.demo11.DragViewGroup>` 这个自定义 View 的完整类名应该是正确的,否则会出现编译错误。
2. `<ImageView android:src="@drawable/tianzige" />` 这里的图片资源 tianzige 应该是存在的,否则会出现运行时错误。
3. `<LinearLayout>` 的子 View 间距建议使用 `android:layout_marginStart` 或 `android:layout_marginEnd` 替代 `android:layout_marginLeft` 或 `android:layout_marginRight`,以适应不同的语言排版方向。
另外,需要注意该代码片段可能存在的其他问题,需要结合实际情况进行分析。
