java.lang.UnsupportedOperationException android arraylist

Question

当我从列表中删除项目时,我得到不受支持的操作异常.

new AlertDialog.Builder(getActivity())
                        .setMessage(result.getString("Message"))
                        .setPositiveButton("OK", new DialogInterface.OnClickListener() {

                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                miPaymentModel.remove(index);
                            })
                        .show();

}

Answer 1

在Arrays.asList返回一个固定大小的列表

从Class API文档here:

Arrays.asList:返回由指定数组支持的固定大小的列表.

你不能add这样; 你不能remove从它.你不能在结构上修改List.

支持这种类型的操作

创建一个LinkedList,支持更快remove.

List<String> list = new LinkedList<String>(Arrays.asList(split));
