This. requestWindowFeature (Window. FEATURE_NO_TITLE); // remove the title bar. this indicates the current Activity.

This code must be added before setContentView.

This. requestWindowFeature (Window. FEATURE_NO_TITLE); setContentView (R. layout. activity_main );View Code

2. Implement in the configuration file

<Application android: icon = "@ drawable/icon" android: label = "@ string/app_name" android: theme = "@ android: style/Theme. NoTitleBar">View Code

In this way, the entire application has no title bar. If you need to set a form without a title bar in an Activity, you just need to set android: theme = "@ android: style/Theme above. noTitleBar "can be written to an Activity.

3. Define in the style. xml file

<? Xml version = "1.0" encoding = "UTF-8"?> <Resources> <style name = "notitle"> <item name = "android: windowNoTitle"> true </item> </style> </resources>View Code

Then reference

<Application android: icon = "@ drawable/icon" android: label = "@ string/app_name" android: theme = "@ style/notitle">View Code <application android: icon = "@ drawable/icon" android: label = "@ string/app_name" android: theme = "@ style/notitle">View Code
