以 OnClickListener 實作每點擊一次後退鍵減少一字元;以 OnLongClickListener 實作當按住後退鍵超過一秒則清空 TextView 上所有文字內容。

新增代碼:
public void delete(View view) {
//show.setText(show.getText().subSequence(0,show.getText().length()-1)); 字串切割法
if(show.getText().equals("")) //防止空按錯誤
{
show.setText("");
}else {
st.pop(); //stak堆疊法
String output = "";
for (String str : st) {
output += str;
}
show.setText(output);
}
}
Button.OnLongClickListener longClickListener = new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
show.setText("");
st.clear();
return true;
}
};
