Question

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

创建类似的布局

我将如何检索输入的值？

您可以从 RecyclerView.Adapter 类

中获取值

<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() + "");
                }
            }
        });

    }
}

Activity.xml

<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>

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;
    }

    public String getPhone() {

    public String getAddress() {
        return Address;
    }

    public void setAddress(String address) {
        Address = address;

}
