You can customize a progress bar. Customizing a ProgressBar requires defining the attribute or properties for the background and progress of your progress bar.

Create an XML file named customprogressbar.xml in your res->drawable folder:

custom_progressbar.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Define the background properties like color etc -->
    <item android:id="@android:id/background">
    <shape>
        <gradient
                android:startColor="#000001"
                android:centerColor="#0b131e"
                android:centerY="1.0"
                android:endColor="#0d1522"
                android:angle="270"
        />
    </shape>
   </item>

  <!-- Define the progress properties like start color, end color etc -->
  <item android:id="@android:id/progress">
    <clip>
        <shape>
            <gradient
                android:startColor="#007A00"
                android:centerColor="#007A00"
                android:centerY="1.0"
                android:endColor="#06101d"
                android:angle="270"
            />
        </shape>
    </clip>
    </item>
</layer-list>

Now you need to set the progressDrawable property in customprogressbar.xml (drawable)

You can do this in the XML file or in the Activity (at run time).

Do the following in your XML:

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleHorizontal"
    android:progressDrawable="@drawable/custom_progressbar"         
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
At run time do the following

// Get the Drawable custom_progressbar                     
    Drawable draw=res.getDrawable(R.drawable.custom_progressbar);
// set the drawable as progress drawable
    progressBar.setProgressDrawable(draw);

The question makes no sense at all. In the question you creates a ProgressDialog, which is infact a descendent of Dialog. A Dialog always have a background white/dark based on Application theme.

If you want just a Progress bar in the Activity,

Add

<ProgressBar  android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:id="@+id/pgBar"
android:indeterminate="true" />

in the Activity/Fragment's layout

And Access the Progressbar like this

ProgressBar pgBar = (ProgressBar) findViewById(R.id.pgBar);
pgBar.setIndeterminate(true);
pgBar.setVisibility(View.Visible)

The default backround for the progress bar is white. We can change the color of the progress bar by using

android:progressDrawable in xml OR
setProgressDrawable(drawable) method programically.

A drawable may be an image directly inserted to drawable folder or create a xml file in drawable folder.xml drawable is preferred since it is more optimal than image.

ProgressBar progessBar = new ProgressBar(MainActivity.this);
        Drawable dr = getResources().getDrawable(R.drawable.pink);
        pDialog.setProgressDrawable(dr);

where pink.xl is the xml file that describes the background for the progressbar
