How to remove the app's head and interface full screen (memo) through styles in Android

In style, it is defined as follows:

<style name="mystyle"> 
 <item name="">true</item><!--No title--> 
 &lt;item name="">true</item><!--Full screen display. If you want the value to change with a certain value, you can use the method of ? to quote it -->
  <!--For example: refer to the value of the title, you can set the value to: "?android:windowNoTitle"--&gt; 
&lt;/style&gt; 

If you want the whole app to be like this, you can change it and refer to the style on the application:

<application android:theme="@style/mystyle"

If you just want to act on an activity, just change the theme of an activity.
