Android: three methods to remove the title bar and full screen


First: a method that is often used when getting started
Add the following code to the onCreate function:
RequestWindowFeature (Window. FEATURE_NO_TITLE); // remove the title bar.
Note that this sentence must be written before the setContentView () method. Otherwise, an error will be reported.


Type 2: defined in the AndroidManifest. xml file
<Application android: icon = "@ drawable/icon" android: label = "@ string/app_name" android: theme = "@ android: style/Theme. NoTitleBar">
As you can see, the entire application will remove the title bar. If you only want to remove the title bar of an Activity, you can add this attribute to the activity tag.




Third: This is not commonly used in general applications. It is to create a style. xml file under the res/values directory, for example:


<? Xml version = "1.0" encoding = "UTF-8"?>


<Resources>


<Style name = "notitle">


<Item name = "android: windowNoTitle"> true </item>


</Style>


</Resources>


In this way, we customize a style, which is equivalent to a topic and then defined in the AndroidManifest. xml file.


<Application android: icon = "@ drawable/icon"


Android: label = "@ string/app_name"


Android: theme = "@ style/notitle">




Three methods to remove the title bar are summarized first. Sometimes we can see that the title bar appears first and then disappears, because we only define it in the oncreate method of activity, the second one is better than the first one, so it won't happen. The third one I personally feel the best. In this way, the functions are separated to facilitate maintenance and expansion.
