调用方法不执行其余代码

Question

我有一个运行的线程从class1调用draw方法，它从class2调用另一个draw方法（下面发布的class2的draw方法）。

class2的draw方法运行一些代码并绘制圆圈，并调用一个名为drawtext的方法。在drawText方法中，它在canvas.drawText之前调用方法调用计算，但是其余的drawText方法（canvas.drawText的代码）不会被执行。

这怎么可能？我想当调用方法时，只是在不中断“父方法”的情况下调用它。

谢谢！

public void draw(Canvas canvas) {
    paint = new Paint();
    double HEIGHT = customView.HEIGHT;
    double WIDTH = customView.WIDTH;
    double margin = customView.margin;
    r = WIDTH / 2 - margin;

    for (int i = 0; i < 10; i++) {
        double randX = getRN();
        double randY = getRN();
        if (Math.hypot(randX - r, randY - r) > r) {
            paint.setColor(Color.WHITE);
        } else {
            paint.setColor(Color.BLACK);
            count++;
        }
        //System.out.println(randX + " " + randY + " " + WIDTH + " " + HEIGHT);
        //System.out.println((randX + margin) + " " + (HEIGHT / 2 - WIDTH / 2 + randY));
        canvas.drawCircle((float) (randX + margin), (float) (randY + HEIGHT / 2 - r), 10, paint);
        total++;
    }
    drawText(canvas);
}

public void drawText(Canvas canvas) {
    paint.setColor(Color.BLACK);
    paint.setTextSize(50);
    paint.setTypeface(Typeface.create(Typeface.DEFAULT, Typeface.BOLD));
    calculate();
    canvas.drawText("Valid / Total: " + count + " / " + total + "  (" + ratioPercentage + ")", 75, 91, paint);
    /*BigDecimal countBig = new BigDecimal(count);
    BigDecimal totalBig = new BigDecimal(total);
    BigDecimal piCalculated = (countBig.divide(totalBig)).multiply(BigDecimal.valueOf(4));*/
    canvas.drawText("Calculated \u03C0 : " + piCalculated, 75, 151, paint);
    canvas.drawText("\"Actual\" \u03c0 : 3.1415926535" , 75, 211, paint);
    //canvas.drawText("Error: " + ((piCalculated.divide(pi)).subtract(BigDecimal.valueOf(1))).multiply(BigDecimal.valueOf(100)) + " %",75, 210, paint);
    canvas.drawText("Error: " + errorPercentage, 75, 271, paint);
}

public void calculate() {
    ratio = (double)count / total;
    ratioPercentage = df.format(ratio);
    piCalculated = df1.format(ratio * 4);
    error = Double.parseDouble(piCalculated) / 3.1415926535 - 1;
    errorPercentage = df2.format(error);
    best = mainActivity.getBest();
    if (total > 5000 && Math.abs(error) < best) {
        System.out.println("Evaluate: best update");
        mainActivity.updateBest(error);
    }
}
