Android：调整 EditText 字体大小以使文本适合一行
我正在制作一个具有两个 EditText 视图的应用程序，用于输入的 txtOne 和用于输出的 txtTwo 。 txtOne 是可编辑的，而 txtTwo 则不可编辑。
我正在寻找一种简单的方法来在这两个视图中缩放文本的字体大小，以便它始终适合视图而不换行。
我发现了一些使用扩展 TextView 的自定义视图来实现此功能，但它们不适合 EditText 视图，或使用 android.graphics.Paint< /code>，这不是我要找的。
有没有什么方法可以检查 EditText 视图中的文本何时换行？如果是这样，那么做类似的事情就很容易了：
if(txtOne.isWrappingText()) {
txtOne.setTextSize(txtOne.getTextSize() - 2);
}
有谁知道有什么方法来检测这个或替代解决方案吗？
I am making an app that has two EditText views, txtOne which is used for input, and txtTwo which is used for output. txtOne is editable, and txtTwo is not.
I am looking for a simple way to scale the font size of the text in these two views so that it always fits within the view without wrapping to a new line.
I have found a few implementations of this using custom views extending TextView, but they aren't fit for an EditText view, or use android.graphics.Paint, which is not what I am looking for.
Is there any way to check to see when text in an EditText view is wrapping? If so, then it would be easy enough to do something like:
if(txtOne.isWrappingText()) {
txtOne.setTextSize(txtOne.getTextSize() - 2);
}
Does anyone know of any way to detect this or an alternative solution?

基本上，建议的代码包含
EditText的TextWatcher，这有助于回答问题。但代码本身就是错误的（我同时测试了它）。我建议阅读这个问题和答案，因为它们解决了非常同样的问题...
I deleted my post
Basically the suggested code contained a
TextWatcherfor theEditText, this helped to answer the question. But the code itself was just wrong (I tested it meanwhile).I suggest to read this question and answers because they adress the very same issue...
