Android and calculating the size of a one-line string in a given font and font size?

问题

Is there an API method for calculating the size (i.e. width and height) of a string displayed on one line and in a given font and font size?

回答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.

回答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);

then make the call of

bounds.width();

bounds.height();

回答3:

The Paint class has a method measureText() which will give you the width in float

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

and another is Paint.getTextBounds
