How to send the data from one xml to another xml layout?

Question

1.First Activity : This Activity has two EditTexts and two Buttons. I need to give login id and password.Here the Buttons contained logging in and cancel:

package com.samelayout;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class SameLayoutActivity extends Activity {
    /** Called when the activity is first created. */
    EditText Myusername;
    EditText Mypassword;
    Button btnlogin;
    Button btncancel;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        btnlogin=(Button)findViewById(R.id.loginbutton);
        btncancel=(Button)findViewById(R.id.cancelbutton);
        Myusername=(EditText)findViewById(R.id.username);
        Mypassword=(EditText)findViewById(R.id.password);    
        btnlogin.setOnClickListener(new OnClickListener()
        {           public void onClick(View v) {
                String str1=Myusername.getText().toString();
                String str2=Mypassword.getText().toString();
                Intent int1=new Intent(getApplicationContext(),Login.class);
                Bundle b= new Bundle();
                b.putString("userdata", str1);
                b.putString("userdata1", str2);
                int1.putExtras(b);
                int1.putExtras(b);
                //(int1);
                startActivityForResult(int1, 0);
            }
        });
    btncancel.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            // TODO Auto-generated method stub
            finish();
        }
    });  
    }
}

2.second Activity: This Activity retrieves the data from the first Activity. I need to show user details to second xml file

package com.samelayout;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class Login extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.login);
        //Intent int1= getIntent();
        Bundle b=this.getIntent().getExtras();
        if(b!=null)
        {
            String str1=b.getString("userdata");
            String str2=b.getString("userdata1");
            TextView tv1=(TextView)findViewById(R.id.text1);
            TextView tv2=(TextView)findViewById(R.id.text2);
            tv1.setText(str1);
            tv2.setText(str2);
            setContentView(tv1);
            setContentView(tv2); }
    } }

3.main.xml here:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/Linearlayout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1"
    android:background="@android:color/darker_gray" >

        <TextView android:layout_width="fill_parent" 
        android:text="Employee ID:" 
        android:layout_height="wrap_content" 
        android:textColor="#0000FF" 
        android:textSize="20sp"/>

        <EditText android:hint="enter ur ID" 
        android:singleLine="true"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:id="@+id/username"/>

        <TextView android:layout_width="fill_parent" 
        android:text="Password:" 
        android:layout_height="wrap_content" 
        android:textColor="#0000FF" 
        android:textSize="20dip"/>

        <EditText android:singleLine="true" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:id="@+id/password" 
        android:password="true"/>

        <Button 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="Submit" 
        android:id="@+id/loginbutton"/>

        <Button 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="Cancel" 
        android:id="@+id/cancelbutton"/>
      </LinearLayout>

4.needed output can be displayed here:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/Linearlayout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1"
    android:background="@android:color/darker_gray" >

    <TextView 
        android:layout_width="fill_parent" 
        android:id="@+id/text1"
        android:text="Employee Name:" 
        android:layout_height="wrap_content" 
        android:textColor="#0000FF" 
        android:textSize="20sp"/>
    <TextView 
        android:layout_width="fill_parent" 
        android:id="@+id/text2"
        android:text="Employee password:" 
        android:layout_height="wrap_content" 
        android:textColor="#0000FF" 
        android:textSize="20sp"/>

    </LinearLayout>

Answer 1

You can achieve this easily by data binding by setting

dataBinding {
    enabled = true
}

inside your Build.gradle(:app)

Now, to send data from one xml to another, look at the below example. In this, I have made a layout named item_top_card.xml which I want to include it in another xml file with different titles. One way is to make different xml for different titles. A good way is to pass the title string from one xml to another as shown :

<include
   android:id="@+id/todays_clicks_parent"
   app:option="@{@string/todays_clicks}"
   layout="@layout/item_top_card" />

You can include the layout xml which you want to include in other xml file as shown above. Notice that here we are passing the string in "option" parameter. This is the parameter name which can be changed as per your needs. Below is the file for item_top_card.xml:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>
        <variable name="option" type="java.lang.String"/>
    </data>

    <com.google.android.material.card.MaterialCardView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minWidth="120dp"
        android:minHeight="120dp"
        android:layout_marginLeft="16dp"
        android:background="@color/transparent"
        app:cardBackgroundColor="@color/white"
        app:cardElevation="0.1dp"
        app:cardCornerRadius="8dp">

        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingVertical="12dp"
            android:paddingLeft="12dp"
            android:paddingRight="24dp">

            <ImageView
                android:id="@+id/icon"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/background_circle"
                android:backgroundTint="@color/purple_light"
                android:paddingHorizontal="12dp"
                android:paddingVertical="12dp"
                android:src="@drawable/clicks"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent" />

            <TextView
                android:id="@+id/title"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="16dp"
                android:lineHeight="24dp"
                android:text="123"
                android:paddingVertical="5dp"

In SameLayoutActivity replace this,

 btnlogin.setOnClickListener(new OnClickListener()
        {           public void onClick(View v) {
                String str1=Myusername.getText().toString();
                String str2=Mypassword.getText().toString();
                Intent int1=new Intent(SameLayoutActivity.this,Login.class);
                Bundle b= new Bundle();
                b.putString("userdata", str1);
                b.putString("userdata1", str2);
                int1.putExtras(b);
                //(int1);
                startActivityForResult(int1, 0);
            }
        });

In your Login Activity, Replace this code, And try again and let me know what happen ..

  TextView tv1=(TextView)findViewById(R.id.text1);
  TextView tv2=(TextView)findViewById(R.id.text2);
if(b!=null)
        {
            String str1=b.getString("userdata");
            String str2=b.getString("userdata1");

            tv1.setText(str1);
            tv2.setText(str2);
            }
    }

Manifest file:

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">
        <activity
            android:label="@string/app_name"
            android:name=".SameLayoutActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".Login"> </activity>
    </application>

</manifest>

You need to pass your data through the Intent used to start the 2nd Activity. Check this blog post out.
