我正在尝试启用“复制到剪贴板”选项。
自爆代码显示了我的MainActivity,它在哪里从数据库中获取数据并将其放在列表视图中
我需要的是用户单击listview字段并可以选择将其文本复制到剪贴板,以便通过短信转发该文本
我正在搜索有关此问题的所有最新帖子,但找不到合适的解决方案
提前致谢!!

最佳答案
ClipboardManager clipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText("label", "Text to copy");
clipboard.setPrimaryClip(clip);
