Hello everyone, let's share a question that beginners may think is strange. Most beginners have such problems, but they do not know how to solve them. I will throw this question and hope it will help you.

Problem description: when the application is started, a black screen will pop up and then enter the mainProgram. When the first black screen is displayed, you will find a title bar information, but you cannot find the page? Very confused, as shown in:

 

The following page is displayed:

 

As shown in, all contain the title bar. The page with the title bar is normal, that is, the page of our main program. Why is the title bar instead of full screen displayed on the previous page? Which page is this?

There are several methods for full screen processing of the program. Let's modify and configure the information in androidmanifest. XML as follows:

<Application Android: icon = "@ drawable/icon"> <br/> <activity Android: Name = ". loadingsystem "Android: Label =" @ string/app_name "Android: theme =" @ Android: style/theme. notitlebar "> <br/> <intent-filter> <br/> <action Android: Name =" android. intent. action. main "/> <br/> <category Android: Name =" android. intent. category. launcher "/> <br/> </intent-filter> <br/> </activity>

Added a property: Android: theme = "@ Android: style/theme. notitlebar", which means that the title bar is not required.

Save and restart. Let's run it to see the effect:

 

The title bar of the first screen does not exist. This page is normal.

 

The title bar of this page also does not exist. The original source is here. Solved.

 

Fault description:

There is also a way to modify the above problems in the program,CodeAs follows:

Public void oncreate (bundle savedinstancestate) {<br/> super. oncreate (savedinstancestate); <br/> // No title <br/> requestwindowfeature (window. feature_no_title); <br/> // full screen <br/> getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen, <br/> windowmanager. layoutparams. flag_fullscreen); </P> <p> setcontentview (R. layout. main); <br/>}

This can also remove the title bar. However, the title bar of the black screen page cannot be removed. It can only work on the page title bar of the current activity. Not global.

 

OK. I hope it will help you. Support me a lot. Top me.
