            ClipboardManager cm = (ClipboardManager) unityActivity.getSystemService(Context.CLIPBOARD_SERVICE);
            // 创建普通字符型ClipData
            ClipData mClipData = ClipData.newPlainText("Label", text);

            cm.setPrimaryClip(mClipData);
    
        }
    }

unity端调用

public static void CopyToB(string phone)
        {
            AndroidJavaObject pluginObject = new AndroidJavaClass("com.luoyikun.clipboard.MyClipboard").CallStatic<AndroidJavaObject>("GetInstance");
            pluginObject.Call("CopyToClipboard", phone);
        }
