I think it does exactly what you want
>> > final Formatter f = new Formatter();
use Formatter(Appendable a)
StringBuilder sb = new StringBuilder();
final Formatter f = new Formatter(sb);
for (Sentinel s : Sentinel.mSentinels) {
if (s.mIsLive) {
pos++;
f.format("%4d%5d", s.mPos.x, s.mPos.y);
canvas.drawText(sb.toString(), x_pos, (pos *
mHalfHeight), mPaint);
}
sb.setLength(0);
see StringBuilder
toString
public String toString()
Returns a string representing the data in this sequence. A new
String object is allocated and initialized to contain the character
sequence currently represented by this object. This String is then
returned. Subsequent changes to this sequence do not affect the
contents of the String.
I assume a String is less costly than a Formatter.
