LukeTaylor  I currently have the same task at hand  creating a popup dialog that contains an EditText    Personally  I find the fully-dynamic route to be somewhat limiting in terms of creativity    FULLY CUSTOM DIALOG LAYOUT    Rather than relying entirely upon Code to create the Dialog  you can fully customize it like so    1  - Create a new Layout Resource file   This will act as your Dialog  allowing for full creative freedom  NOTE  Refer to the Material Design guidelines to help keep things clean and on point   2  - Give ID s to all of your View elements   In my example code below  I have 1 EditText  and 2 Buttons   3  - Create an Activity with a Button  for testing purposes   We ll have it inflate and launch your Dialog    public void buttonClick DialogTest View view         AlertDialog Builder mBuilder   new AlertDialog Builder MainActivity this            Inflate the Layout Resource file you created in Step 1     View mView   getLayoutInflater   inflate R layout timer dialog layout  null            Get View elements from Layout file  Be sure to include inflated view name  mView      final EditText mTimerMinutes    EditText  mView findViewById R id etTimerValue       Button mTimerOk    Button  mView findViewById R id btnTimerOk       Button mTimerCancel    Button  mView findViewById R id btnTimerCancel            Create the AlertDialog using everything we needed from above     mBuilder setView mView       final AlertDialog timerDialog   mBuilder create             Set Listener for the OK Button     mTimerOk setOnClickListener new View OnClickListener              Override         public void onClick  View view                if   mTimerMinutes getText   toString   isEmpty                      Toast makeText MainActivity this   You entered a Value     Toast LENGTH LONG  show                  else                   Toast makeText MainActivity this   Please enter a Value    Toast LENGTH LONG  show                                             Set Listener for the CANCEL Button     mTimerCancel setOnClickListener new View OnClickListener              Override         public void onClick  View view                timerDialog dismiss                               Finally  SHOW your Dialog      timerDialog show              END OF buttonClick DialogTest       Piece of cake  Full creative freedom  Just be sure to follow Material Guidelines     I hope this helps someone  Let me know what you guys think

How about this EXAMPLE  It seems straightforward   final EditText txtUrl   new EditText this       Set the default text to a link of the Queen txtUrl setHint  http   www librarising com astrology celebs images2 QR queenelizabethii jpg     new AlertDialog Builder this     setTitle  Moustachify Link      setMessage  Paste in the link of an image to moustachify       setView txtUrl     setPositiveButton  Moustachify   new DialogInterface OnClickListener         public void onClick DialogInterface dialog  int whichButton          String url   txtUrl getText   toString          moustachify null  url                 setNegativeButton  Cancel   new DialogInterface OnClickListener         public void onClick DialogInterface dialog  int whichButton                  show

If you want some space at left and right of input view  you can add some padding like  private fun showAlertWithTextInputLayout context  Context        val textInputLayout   TextInputLayout context      textInputLayout setPadding          resources getDimensionPixelOffset R dimen dp 19      if you look at android alert dialog xml  you will see the message textview have margin 14dp and padding 5dp  This is the reason why I use 19 here         0          resources getDimensionPixelOffset R dimen dp 19           0           val input   EditText context      textInputLayout hint    Email      textInputLayout addView input       val alert   AlertDialog Builder context           setTitle  Reset Password            setView textInputLayout           setMessage  Please enter your email address            setPositiveButton  Submit     dialog    - gt                 do some thing with input text             dialog cancel                      setNegativeButton  Cancel     dialog    - gt              dialog cancel             create        alert show       dimens xml   lt dimen name  dp 19  gt 19dp lt  dimen gt      Hope it help

Sounds like a good opportunity to use an AlertDialog   As basic as it seems  Android does not have a built-in dialog to do this  as far as I know    Fortunately  it s just a little extra work on top of creating a standard AlertDialog   You simply need to create an EditText for the user to input data  and set it as the view of the AlertDialog   You can customize the type of input allowed using setInputType  if you need   If you re able to use a member variable  you can simply set the variable to the value of the EditText  and it will persist after the dialog has dismissed   If you can t use a member variable  you may need to use a listener to send the string value to the right place    I can edit and elaborate more if this is what you need    Within your class   private String m Text         Within the OnClickListener of your button  or in a function called from there    AlertDialog Builder builder   new AlertDialog Builder this   builder setTitle  Title        Set up the input final EditText input   new EditText this      Specify the type of input expected  this  for example  sets the input as a password  and will mask the text input setInputType InputType TYPE CLASS TEXT   InputType TYPE TEXT VARIATION PASSWORD   builder setView input       Set up the buttons builder setPositiveButton  OK   new DialogInterface OnClickListener           Override     public void onClick DialogInterface dialog  int which            m Text   input getText   toString              builder setNegativeButton  Cancel   new DialogInterface OnClickListener          Override     public void onClick DialogInterface dialog  int which            dialog cancel               builder show

I found it cleaner and more reusable to extend AlertDialog Builder to create a custom dialog class  This is for a dialog that asks the user to input a phone number  A preset phone number can also be supplied by calling setNumber   before calling show     InputSenderDialog java  public class InputSenderDialog extends AlertDialog Builder        public interface InputSenderDialogListener          public abstract void onOK String number           public abstract void onCancel String number              private EditText mNumberEdit       public InputSenderDialog Activity activity  final InputSenderDialogListener listener            super  new ContextThemeWrapper activity  R style AppTheme               SuppressLint  InflateParams      It s OK to use NULL in an AlertDialog it seems            View dialogLayout   LayoutInflater from activity  inflate R layout dialog input sender number  null           setView dialogLayout            mNumberEdit   dialogLayout findViewById R id numberEdit            setPositiveButton  OK   new DialogInterface OnClickListener                  Override             public void onClick DialogInterface dialog  int id                    if  listener    null                       listener onOK String valueOf mNumberEdit getText                                          setNegativeButton  Cancel   new DialogInterface OnClickListener                  Override             public void onClick DialogInterface dialog  int id                    if  listener    null                       listener onCancel String valueOf mNumberEdit getText                                           public InputSenderDialog setNumber String number           mNumberEdit setText  number            return this              Override     public AlertDialog show             AlertDialog dialog   super show            Window window   dialog getWindow            if  window    null               window setSoftInputMode WindowManager LayoutParams SOFT INPUT STATE ALWAYS VISIBLE           return dialog            dialog input sender number xml   lt  xml version  1 0  encoding  utf-8   gt   lt android support constraint ConstraintLayout xmlns android  http   schemas android com apk res android      android layout width  match parent      android layout height  match parent      xmlns app  http   schemas android com apk res-auto      android padding  10dp  gt        lt TextView         android id    id title          android layout width  wrap content          android layout height  wrap content          app layout constraintTop toTopOf  parent          app layout constraintLeft toLeftOf  parent          android paddingBottom  20dp          android text  Input phone number          android textAppearance   style TextAppearance AppCompat Large    gt        lt TextView         android id    id numberLabel          android layout width  wrap content          android layout height  wrap content          app layout constraintTop toBottomOf    id title          app layout constraintLeft toLeftOf  parent          android text  Phone number    gt        lt EditText         android id    id numberEdit          android layout width  match parent          android layout height  wrap content          app layout constraintTop toBottomOf    id numberLabel          app layout constraintLeft toLeftOf  parent          android inputType  phone   gt           lt requestFocus   gt       lt  EditText gt    lt  android support constraint ConstraintLayout gt    Usage   new InputSenderDialog getActivity    new InputSenderDialog InputSenderDialogListener          Override     public void onOK final String number            Log d TAG   The user tapped OK  number is   number               Override     public void onCancel String number            Log d TAG   The user tapped Cancel  number is   number            setNumber someNumberVariable  show
