Android setVisibility无法正常工作

我正在隐藏一个布局，比如说

layoutA

，并使用以下代码显示另一个布局，比如说

layoutB

：

layoutA.setVisibility(View.GONE);
layoutB.setVisibility(View.VISIBLE);

layoutB有一个由计时器控制的图像进度条。问题是，有时隐藏的布局是正确隐藏的。有时，被

layoutB

覆盖的

layoutA

部分即使被隐藏，也会一直闪烁。它仍然可见。有时，它仍然可见

这是我的代码：

layoutA.setVisibility(View.GONE);
layoutB.setVisibility(View.VISIBLE);

tmrOTP = new CountDownTimer(60000, 500) {

    public void onTick(long millisUntilFinished) {
        final int progressToSet = (int) (((60000 - millisUntilFinished)*100)/60000);

        if(!numVerified) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    updateProgressBar(progressToSet);
                }
            });
        }
        else {
            layoutA.setVisibility(View.VISIBLE);
            layoutB.setVisibility(View.GONE);
            tmrOTP.cancel();
        }
    }

    public void onFinish() {
        layoutA.setVisibility(View.VISIBLE);
        layoutB.setVisibility(View.GONE);
        tmrOTP = null;
    }

}.start();

这是我的xml:

            });
        }
        else {

这是布局B-注意：除了进度条覆盖的部分之外，布局A在这里是隐藏的

布局B是否与ProgressBar布局相同？是的，布局B包含ProgressBar共享您的完整xml@sumit，我添加了布局xml@mrid：您是否尝试将背景设置为layoutB的父布局？layoutB是否与ProgressBar布局相同？是的，layoutB包含ProgressBar共享您的完整布局xml@sumit,我已经添加了布局xml@mrid：您是否尝试过将背景设置为layoutB的父布局？
