Question

我是Android新手，我尝试创建注册表单，用户应该可以添加多个用户。

我创建了一个包含表单的布局，并尝试在单击按钮时添加表单，它适用于第一次单击，第二次单击时应用停止添加一个表单，这里是我的代码：< / p>

片段：

public static class NewCaseFragment extends Fragment {


        public NewCaseFragment() {
        }



        //EditText orgname;
        //EditText orgaddress ;



       @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.newcase,
                    container, false);

            View formView = inflater.inflate(R.layout.mform,
                    container, false);

            final LinearLayout formbis = (LinearLayout)rootView. findViewById(R.id.formbis);
            final RelativeLayout form1 = (RelativeLayout)formView. findViewById(R.id.formm);


            Button members= (Button)rootView. findViewById(R.id.members);
            members.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {


                    RelativeLayout formtest = new RelativeLayout(v.getContext());
                    formtest = (RelativeLayout)form1;
                    //TextView tv1 = new TextView(v.getContext());
                   // tv1.setText("Show Up");
                    formbis.addView(formtest);
                }
            });


            return rootView;
        }

表单布局：

Answer 1

问题来自我认为formtest已经formView为父母的事实：

在此声明form1是formView的孩子：

final RelativeLayout form1 = (RelativeLayout)formView. findViewById(R.id.formm);`

然后将formtest设为form1：

formtest = (RelativeLayout)form1;

最后：

formbis.addView(formtest);

但此处formtest无法附加到formbis，因为您已通过formView将其与form1相关联。

动态添加表单：指定的子项已有父项
