如何在Android中利用View显示分数

private void obtainAttrs(Context context, AttributeSet attrs) {    TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.ScoreView);    lineLength = typedArray.getDimension(R.styleable.ScoreView_lineLength, dp2Px(10));    lineColor = typedArray.getColor(R.styleable.ScoreView_lineColor, Color.WHITE);    typedArray.recycle();  }  private void init() {    arrowPaint = createPaint(Color.WHITE, 0, Paint.Style.FILL, 0);    arcPaint = createPaint(lineColor, dp2Px(1), Paint.Style.STROKE, 0);    bgPaint = createPaint(lineColor, dp2Px(1), Paint.Style.FILL, 0);    reachProgressPaint = createPaint(Color.WHITE, dp2Px(1), Paint.Style.FILL, 0);    arcReachPaint = createPaint(Color.WHITE, dp2Px(1), Paint.Style.STROKE, 0);    scoreTextPaint = createPaint(Color.WHITE, 0, Paint.Style.STROKE, dp2Px(26));    descTextPaint = createPaint(Color.WHITE, 0, Paint.Style.STROKE, dp2Px(16));  }
