I want to draw text i开发者_如何学运维nto rectangle on center (horizontally and vertically). If there is too much of a text that crop it what do not fit into rect.
I have try to do it as this example show, but without luck.
Any ideas?
Try this
private void drawRectText(String text, Canvas canvas, Rect r) {
textPaint.setTextSize(20);
textPaint.setTextAlign(Align.CENTER);
int width = r.width();
int numOfChars = textPaint.breakText(text,true,width,null);
int start = (text.length()-numOfChars)/2;
canvas.drawText(text,start,start+numOfChars,r.exactCenterX(),r.exactCenterY(),textPaint);
}
this function worked for me.
private void drawDigit(Canvas canvas, int textSize, float cX, float cY, int color, String text) {
Paint tempTextPaint = new Paint();
tempTextPaint.setAntiAlias(true);
tempTextPaint.setStyle(Paint.Style.FILL);
tempTextPaint.setColor(color);
tempTextPaint.setTextSize(textSize);
float textWidth = tempTextPaint.measureText(text);
//if cX and cY are the origin coordinates of the your rectangle
//cX-(textWidth/2) = The x-coordinate of the origin of the text being drawn
//cY+(textSize/2) = The y-coordinate of the origin of the text being drawn
canvas.drawText(text, cX-(textWidth/2), cY+(textSize/2), tempTextPaint);
}
