나는 화살을 그리려고하고 있지만 정말 이상한 결과를 얻는다. This is how it looks like이 문제는 상당히 명확합니다. 중복되는 부분입니다. onDraw는 방법 내에서Android - 경로로 화살표를 올바르게 그리는 방법?
int radius = 100; //Radius of blue circle to the right
Path leftArrow = new Path();
Paint leftArrowPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
leftArrowPaint.setStyle(Paint.Style.STROKE);
leftArrowPaint.setColor(ContextCompat.getColor(getContext(), R.color.buttonText));
leftArrowPaint.setAlpha(80);
leftArrowPaint.setStrokeWidth(8);
:
//Start point
leftArrow.moveTo(touchX-(radius+5), (int)touchY);
//Line to left
leftArrow.lineTo(touchX-(radius+60), (int)touchY);
//Line up
leftArrow.lineTo(touchX-(radius+30), (int)touchY-30);
//Move back to the middle
leftArrow.moveTo(touchX-(radius+60), (int)touchY);
//Line down
leftArrow.lineTo(touchX-(radius+30), (int)touchY+30);
canvas.drawPath(leftArrow, leftArrowPaint);
leftArrow.reset();
