Add this in your style.xml file

  <style name="dialog_theme" parent="android:style/Theme.Dialog">
        <item name="android:windowMinWidthMajor">90%</item>
        <item name="android:windowMinWidthMinor">90%</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="android:windowBackground">@android:color/transparent</item>
    </style>

Then add this in your dialog initialization place

final Dialog dialog = new Dialog(context, R.style.dialog_theme);
dialog.setContentView(R.layout.research);
dialog.setTitle("Title...");
dialog.show();

try this:

in your res/values/styles:

 <style name="dialog_style" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

Now in your activity use the following code to show the dialog:

     final Dialog dialog = new Dialog(Sample.this,R.style.dialog_style);
     dialog.setContentView(R.layout.research);
     dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PA‌​RENT, ViewGroup.LayoutParams.MATCH_PARENT); 
     dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); 
     dialog.setCancelable(true);
     dialog.setCanceledOnTouchOutside(true);
     dialog.show();

Here ViewGroup.LayoutParams.MATCH_PARENT will fill the screen width

use dialog.getWindow().setLayout(SCREEN_WIDTH, SCREEN_HEIGHT);

simply use WindowManager.LayoutParams() 

final Dialog dialog = new Dialog(getActivity());
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setContentView(R.layout.research);
            WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
            lp.copyFrom(dialog.getWindow().getAttributes());
            lp.width = WindowManager.LayoutParams.MATCH_PARENT;
            lp.height = WindowManager.LayoutParams.MATCH_PARENT;

            dialog.show();
            dialog.getWindow().setAttributes(lp);

    Here width was not fit to full screen and also that white background came along with this :( – Rajakumar Feb 06 '17 at 10:02
  • for background color you can use dialog.getWindow() .setBackgroundDrawable(new ColorDrawable(Color.WHITE)); white may be anything . Try fill parent instead of match parent – Er Kishor Maharjan Feb 06 '17 at 10:07
