Center text inside a circle on a canvas
- by jax
I have the coordinates of the center of a circle where I need to draw some text. The circle may be larger or smaller depending on the attributes I have specified. I have set the center horizontally using mTextBrush.setTextAlign(Align.CENTER);. The problem is that I can't figure out a way to center the text vertically. (See "Draw the counter" below)
//Text Brush setup
mTextBrush = new Paint(Paint.ANTI_ALIAS_FLAG);
mTextBrush.setColor(Color.BLACK);
mTextBrush.setTextSize(1/10*mMaxSize);
mTextBrush.setTextAlign(Align.CENTER);
mTextBrush.setStyle(Paint.Style.STROKE);
private void drawSmallTimer(Canvas canvas) {
//Variable cache
int radiusLocalCache = this.mRadius;
int cx = radiusLocalCache+(radiusLocalCache/2);
int cy = radiusLocalCache-(radiusLocalCache/2);
int radius = radiusLocalCache/3;
//Draw the background circle
canvas.drawCircle(cx, cy, radius, mBackgroundBrush);
//Draw the outline stroke
canvas.drawCircle(cx, cy, radius, mStrokeBrush);
//Draw the counter
String text = String.valueOf(mCounter);
canvas.drawText(text, cx, cy, mTextBrush);
}
