具有重复形式的动态形式
我想在Android中创建一个必须有表单的页面，它会根据某些值动态重复。
这样的事情：
此处形成用户名，密码，移动和地址字段，根据用户在此前页面中输入的数字重复。在这张图片中，表格重复两次，但可能是动态的任何次数。
我怎样才能实现这样的目标？我可以使用listview还是recyclerview？如果是，那么我将如何检索输入的值？

ANS：您应该使用recyclerview
我怎样才能达到这样的目标？
为recyclerview单件
我将如何检索输入的值？
您可以从 RecyclerView.Adapter 类
<强> HERE IS THE SAMPLE CODE
Activity.java
public class AddmoreActivity extends AppCompatActivity {
RecyclerView myRc;
ArrayList<AddMorePojo> arrayList = new ArrayList<>();
Button btnGetData;
AddMoreAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_addmore);
myRc = (RecyclerView) findViewById(R.id.myRc);
btnGetData = (Button) findViewById(R.id.btnGetData);
myRc.setHasFixedSize(true);
myRc.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
AddMorePojo addMorePojo = new AddMorePojo();
addMorePojo.setAddress("");
addMorePojo.setUserName("");
arrayList.add(addMorePojo);
adapter = new AddMoreAdapter(this, arrayList);
myRc.setAdapter(adapter);
btnGetData.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ArrayList<AddMorePojo> pojoArrayList = adapter.getArrayList();
for (int i = 0; i < pojoArrayList.size(); i++) {
Log.e("Name " + i, pojoArrayList.get(i).getUserName() + "");
Log.e("Pass " + i, pojoArrayList.get(i).getPass() + "");
Log.e("PHONE " + i, pojoArrayList.get(i).getPhone() + "");
Log.e("Address " + i, pojoArrayList.get(i).getAddress() + "");
}
}
});
}
}

pojo class
public class AddMorePojo {
String userName, phone, pass, Address;
public AddMorePojo() {

public String getUserName() {
return userName;

public void setUserName(String userName) {
this.userName = userName;

return phone;

public void setPhone(String phone) {
this.phone = phone;

适配器类
public class AddMoreAdapter extends RecyclerView.Adapter<AddMoreAdapter.ViewHolder> {
Context context;
ArrayList<AddMorePojo> arrayList;
public AddMoreAdapter(Context context, ArrayList<AddMorePojo> arrayList) {
this.context = context;
this.arrayList = arrayList;
}
@Override
public AddMoreAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.addmorelayout, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(AddMoreAdapter.ViewHolder holder, int position) {
}
@Override
public int getItemCount() {
return arrayList.size();
}
public ArrayList<AddMorePojo> getArrayList()
{
return arrayList;
}
public class ViewHolder extends RecyclerView.ViewHolder {
EditText edtName, edtPhone, edtPass, edtAdrress;
public ViewHolder(View itemView) {
super(itemView);
edtName = itemView.findViewById(R.id.edtUname);

edtName.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

addMorePOJO.setUserName(charSequence + "");
arrayList.set(getAdapterPosition(), addMorePOJO);
}
@Override
public void afterTextChanged(Editable editable) {
}
});
edtPhone.addTextChangedListener(new TextWatcher() {
