如何更改 Android TextView 的省略号字符串?(... to ...more) [英] How to change the ellipsis string of Android TextView?(... to ...more)

问题描述

我想将省略号字符串从 ... 更改为自定义字符串，例如 abc...[more].但是在TextUtil中，省略号字符串是固定的:

private static final String ELLIPSIS_STRING = new String(ELLIPSIS_NORMAL);

解决方案

我很惊讶还没有任何好的解决方案，所以我花了一些时间编写了自己的自定义 TextView，它允许您显示自定义省略号.我在开发它时想到的几件事:

1. TextView 不应多次绘制文本，因为这是一项繁重的操作，可能会影响性能.
2. 它应该尊重 Spanned 字符串.
3. 支持省略号的自定义文本颜色.

看看，如果你发现任何问题，请告诉我:

I want to change the ellipsis string from ... to custom string, such as abc...[more]. But in TextUtil, the ellipsis string is fixed：

private static final String ELLIPSIS_STRING = new String(ELLIPSIS_NORMAL);

解决方案

I was surprised that there isn't any good solution to that yet, so I spent sometime and wrote my own custom TextView which allows you to show a custom ellipsis. Few things I had in mind while developing it:

1. The TextView shouldn't draw the text more than once since this is a heavy operation and could compromise the performance.
2. It should respect Spanned strings.
3. Support custom text color for the ellipsis.
