How to create a Custom Dialog box in android

Question

I want to create a custom dialog box like below     I have tried the following things    I created a subclass of AlertDialog Builder and used a custom Title and Custom Content View and used that but the result was not as expected  Another attempt was to subclass DialogFragment and customize the dialog inside onCreateDialog that but result was not as expected  Then I tried using a plain Dialog class  The result was not as expected    In all three cases  the problem is when I overlook the title view the size of the dialog is not as expected and when I use Title view the result is there is a thick border around the content view  which really looks bad   Now I have two questions in my mind      How can I achieve that  As I have already tried so many things  a direct answer will be more appreciated  What is the best way to show an error or alert dialog in an android app    EDIT Android Developer Documentation recommends that we should use either DialogFragments or Dialogs for showing Error   Alert Messages to the user  However at one point they say         Tip  If you want a custom dialog  you can instead display an Activity as a dialog instead of using the Dialog APIs  Simply create an activity and set its theme to Theme Holo Dialog in the  manifest element    What is the meaning of that  Isn t it too much to use an Activity just for showing an error message

Here is a very simple way to create a custom dialog.

dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<!--  Put your layout content  -->
</LinearLayout>

MainActivity.java

ShowPopup(){
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.dialog, null);
android.app.AlertDialog.Builder alertDialogBuilder = new 
android.app.AlertDialog.Builder(this);
alertDialogBuilder.setView(promptsView);
alertDialogBuilder.setCancelable(true);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}

Dialog Fragment is the simplest way of creating a custom Alert Dialog Follow the above code to create a custom view for your dialog and then implement it using Dialog Fragment  Add the following code to your layout file      lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android      android layout width  fill parent      android layout height  80dp      android background   3E80B4      android orientation  vertical  gt        lt TextView         android id    id txt dia          android layout width  wrap content          android layout height  wrap content          android layout gravity  center          android layout margin  10dp          android text  Do you realy want to exit            android textColor   android color white          android textSize  15dp          android textStyle  bold    gt         lt LinearLayout         android layout width  wrap content          android layout height  wrap content          android layout gravity  center          android background   3E80B4          android orientation  horizontal  gt            lt Button             android id    id btn yes              android layout width  100dp              android layout height  30dp              android background   android color white              android clickable  true              android text  Yes              android textColor   5DBCD2              android textStyle  bold    gt            lt Button             android id    id btn no              android layout width  100dp              android layout height  30dp              android layout marginLeft  5dp              android background   android color white              android clickable  true              android text  No              android textColor   5DBCD2              android textStyle  bold    gt       lt  LinearLayout gt    lt  LinearLayout gt
