Android: How to Create Multiple Edittext inside an Alert Dialog

Alert Dialogue can be used to display any message to the user or take user choices for some task . We use it in our code to display messages from servers or maybe take single item input. A lot of us may not know that it is also possible to take multiple inputs from a user through alert dialog.

In this blog , I will show you how you can take multiple inputs from a user with edit text inside an alert dialog.

Pre-requisite:

• JDK installed if you want to code in Java.

• Android Studio

Preview of the Output

1) I am adding 4 text views to display the result after submission from the user.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    android:padding="20dp"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/name_person"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="monospace"
        android:gravity="center"
        android:text="Name: "
        android:textColor="@color/colorPrimaryDark"
        android:textSize="25sp" />
    <TextView
        android:id="@+id/age_person"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="monospace"
        android:gravity="center"
        android:text="Age: "
        android:textColor="@color/colorPrimaryDark"
        android:textSize="25sp" />
    <TextView
        android:id="@+id/id_person"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="monospace"
        android:gravity="center"
        android:text="ID: "
        android:textColor="@color/colorPrimaryDark"
        android:textSize="25sp" />
    <TextView
        android:id="@+id/add_person"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="monospace"
        android:gravity="center"
        android:text="Address: "
        android:textColor="@color/colorPrimaryDark"
        android:textSize="25sp" />

<Button
    android:id="@+id/btn"
    android:layout_width="200dp"
    android:layout_height="50dp"
    android:background="#3F51B5"
    android:textColor="#ffffff"
    android:gravity="center"
    android:text="Add Information"
    android:layout_marginTop="10dp"
    android:textSize="22sp"
     />

</LinearLayout>

Design Layout :

2) Now in the drawable/editbox.xml file , I am going to create a style to represent the edit box . I will call it later in the MainActivity by R.drawable.editbox.

editbox.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#DDF2FF" />
    <stroke android:width="0.5dp"
        android:color="#2196F3" />
    <corners
        android:radius="5dp"/>
</shape>

3) In the MainActivity , when the ÄDD Information" button is clicked , the alert dialog is opened. I am setting the background and the gravity through some set functions. All the edittext is containing with a linear layout which have a 20dp margin with the set margin() functions. alertdialog.setView( ) function is a must. Without it , you won't be able to view all the elements. Also don't forget to call adView().

MainActivity.java

package com.example.alertdialogue;

    String name_str,age_str,address_str,id_str;

        super.onCreate( savedInstanceState );
        setContentView( R.layout.activity_main );

        Button button =findViewById( R.id.btn );

        button.setOnClickListener( new View.OnClickListener() {
            @Override

                layoutParams.setMargins( 20,20,20,20); //set margin

                LinearLayout lp=new LinearLayout( getApplicationContext() );
                lp.setOrientation( LinearLayout.VERTICAL );

                lp.addView( name ,layoutParams);
                lp.addView( age,layoutParams );

                alertdialog.setView( lp );
                alertdialog.setPositiveButton( "OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        dialogInterface.dismiss();
                         name_str = name.getText().toString().trim();
                         age_str=age.getText().toString().trim();

                        textViewID.setText( "ID: "+id_str );
                        textViewAdd.setText( "Address: "+address_str );

                    }
                } );

                alertdialog.setNegativeButton( "Cancel", new DialogInterface.OnClickListener() {
                    @Override
