我想知道的WhatsApp如何处理每一封邮件中显示的时间。

I was wondering how WhatsApp handles the time shown in every message.

对于那些谁不知道：

随着 RelativeLayout的和 toLeftOf 我会得到1），而不是2）previous行会被切断当时视图的位置。同样的行为，如果我使用的LinearLayout 。

With a RelativeLayout and toLeftOf I would get 1) but not 2) as previous lines would be "cut off" at the position of the time view. Same behaviour If i use a LinearLayout.

于是，我就用的FrameLayout 或 RelativeLayout的没有文字和时间之间有任何联系。

So I tried to use a FrameLayout or a RelativeLayout without any connection between text and time.

不过，如果文本，只要消息的看法是大的，这两种观点会重叠。 如果我把空字符，给我留言，我不会有时间就对了。

However, if the text is as long as the message-view is big, both views would overlap. If I put blank characters to my message I wouldn't have the time on the right.

难道他们真的有某种文字环绕-LIB为这个还是可以做到的只有布局？

Do they really have some kind of text-wrapping-lib for this or is it possible to do only with layouts?

添加HTML不间断空格的伎俩。测试code的大多数设备和工作精绝。也许WhatsApp的也在做同样的事情。以下是聊天code：

Adding HTML non-breaking spaces did the trick. Tested the code on most devices and working absolutely fine. Maybe whatsapp is also doing the same thing. Below is the chat code:

XML设计：
