如何在android中以编程方式查找TextView的文本区域(高度/宽度) [英] How to find the Text Area(Height/Width) of TextView programmatically in android

问题描述

我有一个 EditText、一个 Button 和一个 TextView.单击按钮时，textview 会显示用 edittext 编写的文本.是否可以根据文本找到占用的文本视图的大小.即如果它有三个字符abc"，那么现在宽度是多少，如果它有五个字符，比如abcde"，那么宽度是多少?

I have an EditText, a Button and a TextView. On clicking the button, textview shows the text written in edittext. Is it possible to find the size of textview occupied depending upon text. i.e. If It has three characters "abc", what is width now, if it has 5 characters like "abcde" , then what is the width ?

推荐答案

Rect bounds = new Rect();
Paint textPaint = textView.getPaint();
textPaint.getTextBounds(text,0,text.length(),bounds);
int height = bounds.height();
int width = bounds.width();

或

textView.setText("bla");
textView.measure(0, 0);
textView.getMeasuredWidth();
textView.getMeasuredHeight();
