In the below example I have created a demo page for user input. Here when user will enter name and phone number then user name and number  will show on same page. Here I have created first Relative layout then in relative layout added Edit text, Text View, Button after that I had declared a class and initialized id of class then I have used OnClickListener()method. You can see below program it will clearly describe you How get user input on same xml.Layout in android

Step(1)activity_main.xml-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/nameText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="18dp"
        android:layout_marginTop="24dp"
        android:text="Name" />

    <EditText
        android:id="@+id/etName"
        android:maxLength="12"

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignTop="@+id/nameText"
        android:ems="10" android:inputType="text"/>

    <TextView
        android:id="@+id/phone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/nameText"

        android:maxLength="12"
     android:layout_marginLeft="100dp"
        android:layout_marginTop="70dp"
        android:layout_toEndOf="@+id/nameText" />


    <Button
        android:id="@+id/send"
        android:layout_width="wrap_content"
        android:layout_marginLeft="20dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="150dp"
        android:text="submit" />
    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="250dp">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="Name"
            android:layout_marginTop="25dp"
            android:layout_marginLeft="10dp"
            android:id="@+id/textView6"
            android:layout_alignParentTop="true"
            android:layout_alignParentStart="true" />

        <TextView
            android:layout_toRightOf="@+id/textView6"
            android:layout_marginTop="28dp"
            android:layout_marginLeft="20dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="New Text"
            android:id="@+id/tvName"
            android:layout_centerHorizontal="true" />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:id="@+id/textView12"
            android:layout_below="@+id/textView6"

        <TextView

            android:id="@+id/tvPhone"/>
        
    </RelativeLayout>
    

</RelativeLayout>

Step(2)MainActivity-
public class MainActivity extends AppCompatActivity {
    EditText etName;
    EditText etPhone;
    TextView tvName;
    TextView tvPhone;
    Button button;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = (Button) findViewById(R.id.send);
        etName=(EditText)findViewById(R.id.etName);
        etPhone=(EditText)findViewById(R.id.etPhone);
        tvName=(TextView)findViewById(R.id.tvName);
        tvPhone=(TextView)findViewById(R.id.tvPhone);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (etName.getText().toString().trim().isEmpty()) {
                    etName.setError("Please enter your name");
                    etName.requestFocus();
                } else if (etPhone.getText().toString().trim().isEmpty()) {
                    etPhone.setError("Please enter your");
                    etPhone.requestFocus();
                } else {
                    tvName.setText(etName.getText().toString() + "!");
                    tvPhone.setText(etPhone.getText().toString()+"!");

                }
            }
        });
