Android并计算给定字体和字体大小的单行字符串的大小？

Question

是否有一种API方法可以计算一行显示的字符串的大小（即宽度和高度）以及给定的字体和字体大小？

Answer 1

Paint p = new Paint();
p.setTypeface(TypeFace obj); // if custom font use `TypeFace.createFromFile`
p.setTextSize(float size);
float textWidth = p.measureText("Your string"); 
// you get the width here and textsize is the height.

Answer 2

Paint mPaint = new Paint();
mPaint.setTextSize(/*put here ur size*/);
mPaint.setTypeface(/* put here ur font type */);
Rect bounds = new Rect();
mPaint.getTextBounds(text, 0, text.length(), bounds);

然后拨打

bounds.width();

bounds.height();

Answer 3

Paint类有一个方法measureText（），它将为您提供float中的宽度

Paint p = new Paint();
int INFO_WINDOW_WIDTH = (int)p.measureText("this is string");

另一个是Paint.getTextBounds
