Android Canvas.drawString display problem
- by Arkaha
Hello everyone!
I encounter this problem when displaying text on SurfaceView, some chars can climb up on others, code is here:
private static void fakeDraw(Canvas c)
{
Paint mPaint = new Paint();
int color = 0xff000000;
mPaint.setColor(color);
mPaint.setStrokeWidth(2);
mPaint.setStyle(Style.FILL);
mPaint.setAntiAlias(true);
FontMetricsInt fm = mPaint.getFontMetricsInt();
int fh = Math.abs(fm.top);
int left = 0;
int top = 100;
Rect smallClip = new Rect(left, top-fh, left + 200, top + 30);
Rect bigClip = new Rect(0, 0, getW(), getH());
c.drawRect(bigClip, mPaint);
String text1 = "Evi";
String text2 = ">>";
String text3 = "Tom";
color = 0xff303030;
mPaint.setColor(color);
c.drawRect(smallClip, mPaint);
color = 0xffffffff;
mPaint.setColor(color);
c.drawText(text1, left, top, mPaint);
Rect bounds = new Rect();
mPaint.getTextBounds(text1, 0, text1.length(), bounds);
left += bounds.width();
c.drawText(text2, left, top, mPaint);
left -= bounds.width();
top += 12;
c.drawText(text3, left, top, mPaint);
mPaint.getTextBounds(text3, 0, text3.length(), bounds);
left += bounds.width();
c.drawText(text2, left, top, mPaint);
}
In the case of a second text Tom all displayed correctly, but the first text Evi not. The problem is that the chars draws in Evi draw space(last char "i")!! It is possible to see if you zoom the picture, what am I doing wrong and how to fix this?
