所以我想做的是一个活动，它有4个选项，用单选按钮和下面的确认按钮创建，我试图做的是每次我选择其中一个4选项并点击＆＃34;确认＆＃34;按钮，出现一个警告对话框并询问客户＆＃34;你选择x2，你确定吗？ ＆＃34;，任何想法如何达到这个目标？
到目前为止我做了什么，但它只适用于第一个＆＃34; x＆＃34;。

除了您的代码包含大量样板文件之外，我注意到if，radioButtonx2和radioButtonx3的{{1}}子句位于radioButtonx4之外点击监听器。
答案 1 :(得分：0)
为清楚起见，请更改：
public void onCheckedChanged(RadioGroup radioGroup, int i) {
为：
public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
然后更改表格的行：
if (radioButtonx.isChecked()){
表格中的行：
if (checkId == R.id.radioButton5) {
