                if (opened) {
                    final int color = R.color.transp;
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        mrecyclerview.setClickable(false);
                        mrecyclerview.setEnabled(false);
                        mrecyclerview.setForeground(new ColorDrawable(ContextCompat.getColor(getContext(), color)));
                    }
                } else {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        mrecyclerview.setClickable(true);
                        mrecyclerview.setEnabled(true);
                        mrecyclerview.setForeground(null);
                    }
                }
            }
        });

推荐答案

您可以像这样向您的适配器添加一个简单的布尔值:

You can add a simple boolean to your adapter like this:

public boolean isClickable = true;

并在您的 fab-click 中进行设置:

and set it in your fab-click:

mAdapter.isClickable = true/false;

并且在适配器中的 OnClickListener 中，仅在可点击时才起作用:

And within your OnClickListener in the Adapter, only act when it is clickable:

public void onClick(View view) {
    if(!isClickable)
        return;
    // do your click stuff
}
