Android下如何计算要显示的字符串所占的宽度和高度
查询了google发现在android一下有几种方法可以做到,但是经过实际测试发现下面这种方法是最准确的
Rect bounds = new Rect(); String text = "Hello World"; TextPaint paint; paint = findViewById(R.id.hello_world).getPaint(); paint.getTextBounds(text, 0, text.length(), bounds); int width = bounds.width();
Paint pFont = new Paint(); Rect rect = new Rect(); pFont.getTextBounds("豆", 0, 1, rect); Log.v(TAG, "height:"+rect.height()+"width:"+rect.width());
