Material Design Progress Dialog with transparent background

I'd like to put an indeterminate Progress Dialog material-compliant in my app. I found two ways to achieve it:
1- Using material-dialogs: https://github.com/afollestad/material-dialogs
2- Using the build-in dialogs of material-design-library: https://github.com/navasmdc/MaterialDesignLibrary#dialog
Using any of these solutions I get something pretty much like this: a dialog with a progressbar in it.
What I'd like to get is just the circular progress bar, without the surrounding light-grey view and without any text. A lot of apps proved us that the user knows that when something's spinning around he just needs to wait: there's no need to write it in letters. What I mean is pretty much something like this, but material.
I don't think this is such a strange question (or is it?) but I wasn't able to find any good answer online. Does anyone of you know how to achieve this?
Thank you
[Edit] I must say that in the gitHub issues of the material-dialogs library this seems to be discussed but the developer closes it fast by saying that it would mean not to follow the guidelines: https://github.com/afollestad/material-dialogs/issues/277

You can use this code,work fine in devices >= 19 (Kitkat)
progress = ProgressDialog.show(Splash.this, null, null, true);
progress.setContentView(R.layout.elemento_progress_splash);
progress.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
progress.show();
element progress splash.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#null"
>
<ProgressBar
android:id="#+id/progressBar1"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/ColorTipografiaAdeudos"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="10dp"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Comprobando sus datos"
android:layout_below="#+id/progressBar1"
android:layout_centerHorizontal="true"
android:id="#+id/textView6"
android:textSize="20dp"
android:textStyle="bold"
android:textColor="#color/ColorFuente"
android:layout_gravity="center_horizontal" />
</RelativeLayout>

To sum up our combined with the author efforts:
The main objective was to get a dialog appearance effect (specifically background dimming) for the progress indicator of a type "material progress wheel" with the transparent background of the dialog itself.
How we've gone about it (one of the possible ways):
This library is used as the material progress wheel.
A separate layout file is created (e.g., progress_wheel.xml) containing the progress wheel layout <com.pnikosis.materialishprogress.ProgressWheel>.... If you find yourself in a situation when the wheel's dimensions do not change as per your layout settings, wrap it with a FrameLayout with wrap_content dimensions.
Inflate this layout with a layout inflater to get a view, e.g. dialogView.
Create the dialog:
Dialog progressDialog = new Dialog(context);
progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
progressDialog.setContentView(dialogView);
progressDialog.show();
Call this function on dialogView to make the dialog background transparent:
public static void clearParentsBackgrounds(View view) {
while (view != null) {
final ViewParent parent = view.getParent();
if (parent instanceof View) {
view = (View) parent;
view.setBackgroundResource(android.graphics.Color.TRANSPARENT);
} else {
view = null;
}
}
}

Android - Pop up a View on top of another View

Suppose I have a Button like what is in the following:
I want once this button is clicked a ImageView(popup message) appears in the top of this button, something like this:
But I do not know how put a View as an overlay on top of another View, Just I know this can be achieved by FrameLayout . Please suppose I want to embed this capability into the Button (in the other phrases I want to create a custom button with a method called showPopup(...) like Textview's setError(...))
Can any one please help me? Thanks

How about taking a look at the Quick Action Dialog?
It is an old article (We're talking Android 2.2 territory), but should still work for the latest devices and OS.
The example uses a contextual popup with buttons, but should be easily modifiable to just show text or whatever you want. There is an example further in that shows use alongside a button.

You can also use RelativeLayout. you can define as on top of other views that way.
Notice that if you define two views, the last one is stacked on the first
http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html

You can use a popupWindow
PopupWindow popupWindow = new PopupWindow(context);
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup_view_layout, null);
Imageview popupImage = popupView.findViewById(R.id.imageView);
popupWindow.setContentView(popupView);
popupWindow.setBackgroundDrawable(null);
int popupY = button.getTop() - button.getHeight();
int popupX = button.getLeft();
popupWindow.showAtLocation(keyView, Gravity.NO_GRAVITY, popupX, popupY);
The popup_view_layout can look like this
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_weight="1"
android:minWidth="20dp"
android:visibility="gone"
app:srcCompat="#drawable/yourImage" />
</FrameLayout>

Android dialog without title not centered horizontally

I always create custom dialog without title to make it centered (both vertical and horizontal) using android:windowNoTitle in styles.xml or requestWindowFeature(Window.FEATURE_NO_TITLE) but some of my dialogs are not center horizontal, for example this dialog:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:padding="20dp"
android:gravity="center"
android:background="#drawable/dialog_bg" >
<include
android:layout_width="wrap_content"
android:layout_height="wrap_content"
layout="#layout/loading_s"/>
<TextView
android:id="#+id/message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:gravity="center_vertical"
android:text="#string/loading"
android:textColor="#color/dialog_text"
android:textSize="#dimen/dialog_title_text_size" />
</LinearLayout>
This is how to create dialog:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
View v = LayoutInflater.from(getActivity()).inflate(R.layout.dlg_progress, null);
Dialog dlg = new Dialog(getActivity(), R.style.My_Dialog_Style); //My_Dialog_Style contains android:windowNoTitle = true
dlg.setContentView(v);
dlg.setCanceledOnTouchOutside(false);
dlg.setCancelable(true);
return dlg;
}
And here is how it appears on screen
If I remove android:windowNoTitle attribute this dialog show correctly so the problem only occurs when using dialog without title.
Does anyone know why this happen and how to make dialog always center on screen?

have you tried looking at this thread?
How to align custom dialog centre in android ?
android:layout_gravity="center"
It looks like its just a layout change, or try using relativeLayout or LinearLayout instead of FrameLayout

When you use Builder and set a custom view with setView, it should not be necessary to remove the Dialog's title and the dialog should be centered.
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.dlg_progress, null));
return builder.create();
}
This is very similar to how it is done in the docs: Creating a Custom Layout

I believe you're running lower the dialog's minimum width attribute. It can be found as
<item type="dimen" name="dialog_min_width_major">65%</item>
in Android's framework. It varies depending on which values folder you're looking at, so it differs depending on density, orientation, etc.
You may be able to overwrite this value in your style. If you set it to something that is definitely smaller than your dialog(10%), it may work properly. If not, read on.
If you notice in your view tree panel, it shows your LinearLayout nested inside 3 FrameLayouts. My guess is that the deepest FrameLayout has its width set to wrap_content, so it's not filling the parent layout and is only as big as your LinearLayout. I can't be sure, though, because the dimensions are chopped off in your picture.
Why it changes when you remove the title? I don't know. You can hack it by adjusting the padding/layout params in onMeasure, but it seems like there should be a cleaner way to do it.

Still don't know why removing title make Dialog not centered horizontally but when I set min_width attr of LinearLayout = dialog minWidth this problem gone away.

Android ScrollView in dialog doesn't show the top of the inner TableLayout when rotating

I have the layout of a configuration dialog in an XML like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/timerConfigurationDialog"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:scrollbars="vertical" >
...
</TableLayout>
</ScrollView>
And I use the following code to inflate it:
LayoutInflater inflater = (LayoutInflater) this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.timer_configuration_dialog,
(ViewGroup) findViewById(R.id.timerConfigurationDialog));
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout)
.setTitle(R.string.configure)
...;
When I test it in the emulator there is no problem when the screen is vertical because all the components of the dialog are visible but, when the screen is horizontal, the first row and the upper half of the second row are not visible (and, of course, they are out of the reach of the scroll).
I have tried different combinations of layouts without success... any help will be appreciated!!
Thanks in advance,
Raúl

As there were no answer, I have changed the layout of the dialog. Now, I don´t use the TableLayout inside the ScrollView... instead I have a LinearLayout inside the ScrollView, so there is no problem with the dialog when the user rotates the screen.

Understanding android dialog layouts

I'm making a simple custom dialog for my android app, displaying only a seek bar. However, the complications of this simple task are driving me nuts.
My layout for the dialog is as follows:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp">
<SeekBar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/dialogVolumeSlider"
android:layout_width="225dp"
android:layout_height="wrap_content"/>
</LinearLayout>
The dialog is created in code:
Dialog d = new Dialog(this);
d.setContentView(R.layout.custom_dialog);
return d;
Instead of a simple box wrapping the seekbar, I get this phantom space coming from somewhere:
What's the issue here? I've tried modifying
d.getWindow().getAttributes().height
but this creates additional problems as well.
Thanks for any help!!
EDIT: Stranger things happen when I assigned a fixed "50dp" to my LinearLayout's layout_height:

By default a Dialog will leave space for a title even if you don't set one (with d.setTitle()) .
You can either set a title to fill the space or request that the Dialog not have a title.
Here is an example of how to request the no title setting.
Dialog d = new Dialog(this);
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(R.layout.custom_dialog);
With no title, your SeekBar will appear as you expect.

Try putting a fixed Height on your parent linear layout. Something like:
android:layout_height="50px"
