Java 声音播放早于视图更改

我正在android studio中创建一个钢琴应用程序：

我的播放按钮有一个点击式监听器，当按下该按钮时，录音和播放按钮将不可见，播放录制的声音时，停止按钮将可见

播放按钮

mBtn_Play.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            mRecordingState = "Playing";
            switchButtonVisibility();

            for (final int sound: mListRecordedSounds )
            {
                if (mRecordingState == "Ready")
                {//break out of loop when stop button is pressed
                    break;
                }
                else {

                    mSoundPool.play(sound, 1,1,1,0,1);
                    try
                    {
                        Thread.sleep(500);
                    }
                    catch (InterruptedException e)
                    {
                        e.printStackTrace();
                    }
                }
            }
        }
    });
}

切换按钮可见性的方法

private void switchButtonVisibility()
{

    if (mRecordingState != "Ready")
    {
        mBtn_Stop.setVisibility(View.VISIBLE);
        mBtn_Record.setVisibility(View.GONE);
        mBtn_Play.setVisibility(View.GONE);

    }
    else
    {
        mBtn_Stop.setVisibility(View.GONE);
        mBtn_Record.setVisibility(View.VISIBLE);
        mBtn_Play.setVisibility(View.VISIBLE);
    }

}

mBtn_Record.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            mListRecordedSounds.clear();
            mRecordingState = "Recording";
            switchButtonVisibility();

        }
    });
mBtn_Stop.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            mRecordingState = "Ready";
            switchButtonVisibility();
        }
    });

使用“录制”和“停止”按钮，该功能正常运行

private void switchButtonVisibility()
{

    if (mRecordingState != "Ready")
    {
        mBtn_Stop.setVisibility(View.VISIBLE);
        mBtn_Record.setVisibility(View.GONE);
        mBtn_Play.setVisibility(View.GONE);

    }
    else
    {
        mBtn_Stop.setVisibility(View.GONE);
        mBtn_Record.setVisibility(View.VISIBLE);
        mBtn_Play.setVisibility(View.VISIBLE);
    }

}

mBtn_Record.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            mListRecordedSounds.clear();
            mRecordingState = "Recording";
            switchButtonVisibility();

        }
    });
mBtn_Stop.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            mRecordingState = "Ready";
            switchButtonVisibility();
        }
    });

出于某种奇怪的原因，它首先执行

For

循环，然后在

开关按钮可视性（）之前播放声音方法更改哪些按钮可见。这似乎没有任何意义，因为该方法位于循环之上。有没有办法设置它，使按钮的可见性在启动前先更改
执行循环并播放声音？
延迟执行，在视图上发布事件。这将确保在视图更新后立即执行操作：


    @Override
    public void onClick(View v) {
        mRecordingState = "Playing";
        switchButtonVisibility();

        mBtn_Play.post(new Runnable() {
            @Override
            public void run() {
                for (final int sound : mListRecordedSounds ) {
                    // play the sound here
                    ...
                }
            }
        });
    }

谢谢你，@azizbekian你已经解决了我的问题。除了应该是
mbtnu Play.post（new Runnable（）{
而不是
mbtnu Stop.post（new Runnable（）{
Nice！更新了答案之外。
