我的布局文件结构:
FrameLayout{
LinearLayout{
cardview_1
card_view_2}}

使用recyclerView并使用cardView作为root View创建rowItemLayout.xml或columnItemLayout.xml。 然后使用recyclerView的功能,例如:
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(createHelperCallback());
itemTouchHelper.attachToRecyclerView(recyclerView);
private ItemTouchHelper.Callback createHelperCallback() {
ItemTouchHelper.SimpleCallback simpleItemTouchCallback =
new ItemTouchHelper.SimpleCallback(ItemTouchHelper.UP | ItemTouchHelper.DOWN,
ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
@Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder,
RecyclerView.ViewHolder target) {
moveItem(viewHolder.getAdapterPosition(), target.getAdapterPosition());
return true;
}
@Override
public void onSwiped(final RecyclerView.ViewHolder viewHolder, int swipeDir) {
deleteItem(viewHolder.getAdapterPosition());
}
};
return simpleItemTouchCallback;
}
private void moveItem(int oldPos, int newPos) {
ListItem item = (ListItem) listData.get(oldPos);
listData.remove(oldPos);
listData.add(newPos, item);
adapter.notifyItemMoved(oldPos, newPos);
}
private void deleteItem(final int position) {
listData.remove(position);
adapter.notifyItemRemoved(position);
}
