当我按下提交按钮时，同样的活动重新打开（清除所有选中的单选按钮）。只有当用户已经注册时才会发生这种情况。在Android中按下提交按钮后，同样的活动重新开始
当用户是新的时使用firebase，然后新的活动打开（MatchFind.class），这是正确的。
代码
bSubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
DatabaseReference current_user_db = mDatabase.child(user_id);
int id1 = r1.getCheckedRadioButtonId();
int id2 = r2.getCheckedRadioButtonId();
int id3 = r3.getCheckedRadioButtonId();
int id4 = r4.getCheckedRadioButtonId();
int id5 = r5.getCheckedRadioButtonId();
int id6 = r6.getCheckedRadioButtonId();
int id7 = r7.getCheckedRadioButtonId();
int id8 = r8.getCheckedRadioButtonId();
int id9 = r9.getCheckedRadioButtonId();
int id10 = r10.getCheckedRadioButtonId();

这是您的完整密码吗？ – Noorul
请添加您的问题类和MatchFind类的完整代码。我可以假设你在MatchFind活动中错误地使用了相同的布局。 –
@VadimsSavjolovs都能跟得上我用正确的布局文件 –
