Here's一个完整的例子,似乎可以完成您想要做的大部分工作。似乎唯一需要做的更改是创建一个新的ImageView并将位图复制到其中。为此,您需要将类MyDragListener的onDrag()方法更改为:
case DragEvent.ACTION_DROP:
// Dropped, reassign View to ViewGroup
View view = (View) event.getLocalState();
//ViewGroup owner = (ViewGroup) view.getParent(); // Removed
//owner.removeView(view); // Removed
LinearLayout container = (LinearLayout) v;
// Added the following to copy the old view's bitmap to a new ImageView:
ImageView oldView = (ImageView) view;
ImageView newView = new ImageView(getApplicationContext());
newView.setImageBitmap(((BitmapDrawable) oldView.getDrawable()).getBitmap());
container.addView(newView); // Changed to add new view instead
view.setVisibility(View.VISIBLE);
break;
