Hi the question has answered, but generally if you want to get context in fragment or dialogFragment use this

protected lateinit var baseActivity: BaseActivity
protected lateinit var contextFragment: Context

override fun onAttach(context: Context) {
    super.onAttach(context)
    if (context is BaseActivity) {
        this.baseActivity = context
    }
    this.contextFragment = context
}

and in java

 protected BaseActivity baseActivity;
 protected Context context;

 @Override
 public void onAttach(@NonNull Context context) {
    super.onAttach(context);
    this.context = context;
    if (context instanceof BaseActivity) {
        this.baseActivity = (BaseActivity) context;
    }
}
