Android 动态删除按钮

Question

我有一个按钮，当我按下它时，我想将其移除(而不是使其不可见)。我读到我可以使用 layout.removeView(mybutton) 来做到这一点，但布局是什么？我怎样才能在我的 Activity 中得到它

Button showQuestion;
private void initialize() {
    showQuestion = (Button) findViewById(R.id.bAnswerQuestionShowQuestion);
}
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.bAnswerQuestionShowQuestion:
                showQuestion.setVisibility(View.INVISIBLE);
                //Here i want to delete the button
                question.setVisibility(View.VISIBLE);
                theAnswer.setVisibility(View.VISIBLE);
                answerQuestion.setVisibility(View.VISIBLE);
                showChoices.setVisibility(View.VISIBLE);
                showHint.setVisibility(View.VISIBLE);
            break;
    }
}

ViewGroup layout = (ViewGroup) button.getParent();
if(null!=layout) //for safety only  as you are doing onClick
  layout.removeView(button);
