获取 TextView 中文本的大小 [英] Get the size of a text in TextView

问题描述

我在将 textView 放置在指定中心的 x 和 y 坐标时遇到问题.首先，我尝试在 textView 中设置文本，并以视图的宽度和高度移动视图从这个链接.

I have a problem placing a textView at specified center's x and y coordinates. Firstly, I tried to set the text in the textView, and to move the view with the width and the height of the view from this link.

但它不起作用，我想尝试其他方法.我想知道是否有一种方法可以获取指定文本在我的 textView 中的大小?我的意思是，我知道 text 和 textSize，如何获得 textView 的宽度和高度?

But it doesn't work, and I'd like to try something else. I'd like to know if there is a method to get the size which a specified text will take in my textView? I mean, I know the text and the textSize, how can I get the width and the height my textView will take?

类似于 (NSString)sizeWithFont; 的方法，适合那些了解 iPhone 开发的人.

Something like the method (NSString)sizeWithFont; for those who know iPhone dev.

推荐答案

如果你的textview叫做tv

If your textview is called tv

tv.setText("bla");
tv.measure(0, 0);       //must call measure!
tv.getMeasuredHeight(); //get height
tv.getMeasuredWidth();  //get width
