我需要删除发送后从listview计划...我收到此错误：java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0 broadcast receiver尝试发送短信时，但是当我单击"计划"按钮时，它会添加到list view......现在我给你看我的代码！
提前感谢大家！
希望你能帮到我！
PS：如果我添加了此方法：
@Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
//Toast.makeText(MainActivity.this, "Item has been added into your list", Toast.LENGTH_LONG)
// .show();
dataSms.remove(position);
adapter.notifyDataSetChanged();
}
它可以工作，但我希望在发送短信后自动删除第一项！

错误在堆栈跟踪中：
dataSms = new ArrayList<Sms>();
// ...
dataSms.remove(0);
您从不在列表中添加项目，但想要删除一个
ArrayList 中没有数据。这就是堆栈跟踪说大小为 0 的原因。如果大小为 0，那么您如何从 ArrayList 中删除元素。
删除此行dataSms.remove(0);
请检查您声明的 ArrayList。我想在声明您没有在数组列表中添加任何内容之后。
dataSms = new ArrayList<Sms>();
我建议你逐行调试。在尝试从 arrayList 中删除值之前。尝试检查其大小是否为零或为空。如果没有，那么您可以尝试下一步。
dataSms.remove(0);
请投票并标记解决方案是否有用。
谢谢！
