如何确定在 Android 中的 TextView 中可以容纳多少文本? [英] How do I determine how much text will fit in a TextView in Android?

问题描述

我的布局看起来像这样:

I have a layout that looks something like this:

[TextView 1] [TextView 2]
[ TextView 2 spill-over ]

本质上，我需要将 TextView 2 的内容换行到下一行，但从 TextView 1 开始的地方开始.我在想，如果我知道 TextView 2 在第一行空间不足之前可以容纳多少文本，我可以将其余文本放入前两个下方的另一个 TextView 中.所以我需要测量有多少文本可以放入 TextView (这可能很棘手，因为据我所知，Android 会尝试在 TextView 中的一个好位置打破文本，这样它就不会在中间如果可以避免)或者我需要一个关于如何布局的新想法.

Essentially, I need the contents of TextView 2 to wrap to the next line, but start where TextView 1 starts. I was thinking that if I knew how much text would fit into TextView 2 before it runs out of space on line one, I could take the rest of the text and put it in another TextView below the first two. So I need to measure how much text will fit into a TextView (which can be tricky because as far as I can tell, Android will try to break the text in a TextView at a good location so that it won't break a word in the middle if it can be avoided) or I need a new idea on how to lay this out.

任何帮助将不胜感激.

提前致谢，

推荐答案

不幸的是，Paint.breakText 没有返回与在我的两行 TextView 中看到的完全相同的结果.

Unfortunately, Paint.breakText didn't return the exact same result as in was seen in my two-line TextView.

但是，这行得通

int numChars = textView.getLayout().getLineEnd(1);

(使用 numberOfLines - 1 作为参数)

(use numberOfLines - 1 as the parameter to it)

参考http://developer.android.com/reference/android/text/Layout.html#getLineEnd(int)将TextView的单行设置为不同的宽度
