使用分割字符串自定义分享按钮的意图或如何拆分字符串并替换奇怪的逗号

Question

描述：我想使用分享按钮。使用分享按钮用户发送列表作为消息。在列表中，每个项目都有标题+描述 问题：系统从列表中获取所有项目，并使用逗号依次将其放入行中。

我：TitleItemOne，DescriptionItemOne，TitleItemTwo，DescriptionItemTwo

我需要：
TitleItemOne - DescriptionItemOne
TitleItemTwo - DescriptionItemTwo

或者： 也许更容易更换所有奇数逗号 “”与“ - ”所以它会这样我正在寻找的风格。

这是代码（在Sharebutton方法所需的代码）

Answer 1

变化

test.add(cursor.getString(cursor.getColumnIndex(ListContract.ListEntry.COLUMN_ITEM_NAME))); //add the item test.add(cursor.getString(cursor.getColumnIndex(ListContract.ListEntry.COLUMN_ITEM_DESCRIPTION)));

要

test.add(cursor.getString(cursor.getColumnIndex(ListContract.ListEntry.COLUMN_ITEM_NAME)) + "-" + (cursor.getString(cursor.getColumnIndex(ListContract.ListEntry.COLUMN_ITEM_DESCRIPTION)));

注： 我可能没有全部括号正确关闭，但你有想法

Answer 2

可以格式化你的串到HTML或使用"\n"

字符串HTML：

可以使用Html.fromHtml()以在您的字符串中使用HTML标记：

Html.fromHtml("<h2>Title</h2><br><p>Description here</p>")); 

使用"\n"可以使用System.getProperty("line.separator")至极取决于操作系统行分隔符
