我是 android 新手,我正在尝试创建一个注册表单,用户应该能够添加多个用户。

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,并且应用程序在第二次单击时停止以添加更多表单,这是我的代码:

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:

        android:id="@+id/formm"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding="5dp" >

            android:entries="@array/role"
            android:prompt="@string/role"
            android:textSize="10sp" />

        <EditText

            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/oparea"
            android:hint="@string/job"
            android:inputType="text"
            android:textSize="12sp" />

        <EditText
            android:id="@+id/phone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/job"
            android:hint="@string/phone"
            android:inputType="phone"
            android:textSize="12sp" />

        <EditText
            android:id="@+id/email"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/phone"
            android:hint="@string/email"
            android:inputType="text"
            android:textSize="12sp" />
    </RelativeLayout>

问题来自我认为formtest已经formView作为父母的事实:

在这里,您声明它form1是 formView 的子项:

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

然后你设置formtestform1

formtest = (RelativeLayout)form1;

最后:

formbis.addView(formtest);

但是这里formtest不能附加,formbis因为您已经将它链接到formViewthrough form1
