ViewPager具有对话框主题的活动

Question

I have an activity with a dialog theme (Theme.AppCompat.Light.Dialog.Alert) Inside this activity i created a ViewPager because i want one image slider. But my ViewPager create something like an actionBar before the slider. How can i remove it?

If my activity had an normal theme (not like a dialog) i could hide it doing the following code:

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)

But it doesn't work in a dialog theme....

EDIT

My problem:

I want remove the "PageViewExample" =/

i already tried the following string and nothing happens

requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 1

I just added some style to my theme.

<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
