android - 根据操作设置按钮可见性

Question

我在主要活动中创建了一个按钮来授予权限。如果用户仍然拥有权限，我想将按钮的可见性设置为消失，如果没有，我希望按钮再次出现。有什么建议么？

if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_CALENDAR)
            != PackageManager.PERMISSION_GRANTED) {
    Button.setVisibility(View.Visible);
    } else {
    Button.setVisibility(View.GONE);
    }

    OR

    if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_CALENDAR)
            != PackageManager.PERMISSION_GRANTED) {
    Button.setVisibility(View.Visible);
    } else (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_CALENDAR)
            != PackageManager.PERMISSION_DENIED){
    Button.setVisibility(View.GONE);
    }
