Answer 1

In addition to arunsoorya's answer :

Change slide_up_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromYDelta="0%p"
    android:toYDelta="100%p" />

And slide_out_down.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromYDelta="0%p" 
    android:toYDelta="50%p"
    android:duration="@android:integer/config_longAnimTime"/>

Answer 2

For this, you need 2 animations and put this in the res/anim folder

1. slide_up_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromYDelta="50%p" android:toYDelta="0%p"
    android:duration="@android:integer/config_longAnimTime"/>

2.slide_out_down.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromYDelta="0%p"
    android:toYDelta="100%p" />

Now you have to create a custom style in style.xml

<style name="DialogAnimation">
        <item name="android:windowEnterAnimation">@anim/slide_up_dialog</item>
        <item name="android:windowExitAnimation">@anim/slide_out_down</item>
</style>

Next is to extend the android Theme. Dialog theme in the same style.xml and give the reference to the custom style we created.

<!-- Animation for dialog box -->
    <style name="DialogSlideAnim" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/DialogAnimation</item>
    </style>

And finally, call this style when you create the dialog like this.

dialog = new Dialog(new ContextThemeWrapper(this, R.style.DialogSlideAnim));

yep...Now the Dialog is ready to slide.....!!

Update:

As @MichealP suggested, this will place the window at the bottom

getWindow().setGravity(Gravity.BOTTOM); 

and modify the style to remove tittle and background

<item name="android:windowBackground">@null</item> 
<item name="android:windowFrame">@null</item> 
<item name="android:windowNoTitle">true</item>

As @sikni8 suggested this will make the black border transparent

getWindow().setBackgroundDrawableResource(android.R.color.transparent);
