Android How to create a Dialog without a title

Question

I m trying to generate a custom dialog in Android   I create my Dialog like this   dialog   new Dialog this   dialog setContentView R layout my dialog     Everythings works fine except for the title of the Dialog  Even if I don t set the title of the dialog the dialog popup has a blank space at the position of the dialog    Is there any way to hide this part of the Dialog    I tried it with an AlertDialog but it seems the layout is not set properly    LayoutInflater inflater         LayoutInflater  this getSystemService Context LAYOUT INFLATER SERVICE   View view   inflater inflate R layout map dialog  null    AlertDialog Builder builder   new AlertDialog Builder this   builder setView view       dialog   new Dialog this      dialog setContentView R layout map dialog    dialog   builder create       TextView  dialog findViewById R id nr   setText number     If I use this code I get a null Pointer Exception in the last line   The dialog is not null so the TextView I try to retrieve does not exist  If I uncomment the part where I use the Dialog Constructor everything works fine but for the title above my dialog layout

FEATURE NO TITLE works when creating a dialog from scratch  as in   Dialog dialog   new Dialog context   dialog requestWindowFeature Window FEATURE NO TITLE     But it doesn t work when creating an AlertDialog  or using the Builder   because it already disables the title and use a custom one internally   I have looked at the SDK sources  and I think that it can t be worked around  So to remove the top spacing  the only solution is to create a custom dialog from scratch IMO  by using the Dialog class directly   Also  one can do that with a style  eg in styles xml    lt style name  FullHeightDialog  parent  android style Theme Dialog  gt      lt item name  android windowNoTitle  gt true lt  item gt   lt  style gt    And then   Dialog dialog   new Dialog context  R style FullHeightDialog

You can hide the title of a dialog using   dialog requestWindowFeature Window FEATURE NO TITLE      Previous version of this answer  which is overcomplicated   You need to use an AlertDialog  There s a good explanation on the Android Developer s site about custom dialogs   In very short summary  you do this with code like copied below from the official website  That takes a custom layot file  inflates it  gives it some basic text and icon  then creates it  You d show it then with alertDialog show     AlertDialog Builder builder  AlertDialog alertDialog   Context mContext   getApplicationContext    LayoutInflater inflater    LayoutInflater          mContext getSystemService LAYOUT INFLATER SERVICE   View layout   inflater inflate R layout custom dialog           ViewGroup  findViewById R id layout root     TextView text    TextView  layout findViewById R id text   text setText  Hello  this is a custom dialog     ImageView image    ImageView  layout findViewById R id image   image setImageResource R drawable android    builder   new AlertDialog Builder mContext   builder setView layout   alertDialog   builder create      In response to comment   I assume that TextView with the id nr is in the View you are inflating with View view   inflater      If so  then you need to change just one bit  instead of dialog findView    make it view findView     Then once you ve done that  remember to use dialog show    or even builder show   without bothering to do builder create

In your code add this line  requestWindowFeature Window FEATURE NO TITLE       Or in XML use a theme  android theme   android style Theme NoTitleBar    XML would be a better implementation as with the code version the title bar gets created and then removed which is a waste of resource     Ok good try but it is not working  I   get    android view WindowManager BadTokenException    Unable to add window -- token null is   not for an application if I want to   shwo the dialog    Change the alert dialog type to system dialog   e g   TYPE SYSTEM OVERLAY   and see if this resolves your issue

olivierg s answer worked for me and is the best solution if creating a custom Dialog class is the route you want to go   However  it bothered me that I couldn t use the AlertDialog class  I wanted to be able to use the default system AlertDialog style  Creating a custom dialog class would not have this style   So I found a solution  hack  that will work without having to create a custom class  you can use the existing builders   The AlertDialog puts a View above your content view as a placeholder for the title  If you find the view and set the height to 0  the space goes away   I have tested this on 2 3 and 3 0 so far  it is possible it doesn t work on every version yet   Here are two helper methods for doing it          Show a Dialog with the extra title top padding collapsed          param customView The custom view that you added to the dialog     param dialog The dialog to display without top spacing         param show Whether or not to call dialog show   at the end      public static void showDialogWithNoTopSpace final View customView  final Dialog dialog  boolean show           Now we setup a listener to detect as soon as the dialog has shown      customView getViewTreeObserver   addOnGlobalLayoutListener new OnGlobalLayoutListener               Override         public void onGlobalLayout                    Check if your view has been laid out yet             if  customView getHeight    gt  0                       If it has been  we will search the view hierarchy for the view that is responsible for the extra space                   LinearLayout dialogLayout   findDialogLinearLayout customView                   if  dialogLayout    null                           Could find it  Unexpected                     else                          Found it  now remove the height of the title area                     View child   dialogLayout getChildAt 0                       if  child    customView                               remove height                         LinearLayout LayoutParams lp    LinearLayout LayoutParams  child getLayoutParams                            lp height   0                          child setLayoutParams lp                          else                              Could find it  Unexpected                                                              Done with the listener                 customView getViewTreeObserver   removeGlobalOnLayoutListener this                                             Show the dialog     if  show               dialog show              Searches parents for a LinearLayout         param view to search the search from     return the first parent view that is a LinearLayout or null if none was found     public static LinearLayout findDialogLinearLayout View view        ViewParent parent    ViewParent  view getParent        if  parent    null            if  parent instanceof LinearLayout                   Found it             return  LinearLayout  parent             else if  parent instanceof View                   Keep looking             return findDialogLinearLayout  View  parent                            Couldn t find it     return null      Here is an example of how it is used       Dialog dialog   new AlertDialog Builder this           setView yourCustomView           create         showDialogWithNoTopSpace yourCustomView  dialog  true     If you are using this with a DialogFragment  override the DialogFragment s onCreateDialog method  Then create and return your dialog like the first example above  The only change is that you should pass false as the 3rd parameter  show  so that it doesn t call show   on the dialog   The DialogFragment will handle that later   Example    Override public Dialog onCreateDialog Bundle savedInstanceState        Dialog dialog   new AlertDialog Builder getContext             setView yourCustomView           create         showDialogWithNoTopSpace yourCustomView  dialog  false       return dialog      As I test this further I ll be sure to update with any additional tweaks needed
