You can create a custom Dialog and use is to show the alert. Something like below should work

    Dialog dialogView = new Dialog(mActivity, android.R.style.ThemeDeviceDefaultLightNoActionBar);

    dialogView.setContentView(R.layout.custom_alert_layout);
    dialogView.show();

The above will also enable you to make any customizations that you would like your alert to display.

Try instead:

builder.requestWindowFeature (Window_FEATURE_NO_TITLE);

use this:

builder.supportRequestWindowFeature (Window.FEATURE_NO_TITLE);

You are requesting the feature on the builder, not on the dialog. call the requestWindowFeature(Window_FEATURE_NO_TITLE) after you call the create() method on the builder, which returns an AlertDialog and then call requestWindowFeature(Window_FEATURE_NO_TITLE). And you should request the feature before setting the view of the dialog. You can request the feature in onCreate of the dialog like getDialog().requestWindowFeature(Window_FEATURE_NO_TITLE)
