单击按钮后如何停止滚动查看到滚动顶部？

Question

我正在开发我的第一个应用程序并让它像我想要的那样工作，只有一个小例外。问题出在scrollview中，相对布局最多包含20个按钮。当我向下滚动并单击底部附近的按钮时，滚动视图会在单击后滚动回到顶部。我希望scrollview在点击后保持原样。例如，在单击按钮18之后，我不希望用户必须向下滚动到底部以单击按钮19.有人可以告诉我如何在单击后停止滚动视图自动滚动到顶部。

以下是其中一个按钮的OnClickListener的JAVA代码。

    runner[18].setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (runnerRunning[18]) {
                time[18] = System.currentTimeMillis() - startTime;
                runners.get(18).setTime(formatTime(time[18]));
                runnerTime[18].setText(formatTime(time[18]));
                runnerRunning[18] = false;
            }
        }
    });
