获取字体的长度
Rect rect = new Rect();
paint.getTextBounds(getLabel(), 0, getLabel().length(), rect);
int strwid = rect.width()/2;
int strhei = rect.height()/2;
canvas.drawText(getLabel(), cx-strwid, cy+strhei, paint);
获取屏幕size
@SuppressLint("NewApi")
public static Point getDisplaySize(Activity act) {
WindowManager m = act.getWindowManager();
Display d = m.getDefaultDisplay(); // 为获取屏幕宽、高
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
Point outSize = new Point();
d.getSize(outSize);
return outSize;
} else {
Point p = new Point(d.getWidth(), d.getHeight());
return p;
}
}
}
