Can't see to get this to work. I just want the title and statusbar to be gone in the following code:

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. package org.panel;
  2.  
  3.  
  4.  
  5. import org.panel.Panel.OnPanelListener;
  6.  
  7. import easing.interpolator.BounceInterpolator;
  8.  
  9. import easing.interpolator.EasingType.Type;
  10.  
  11. import android.app.Activity;
  12.  
  13. import android.os.Bundle;
  14.  
  15. import android.util.Log;
  16.  
  17.  
  18.  
  19. public class Test extends Activity implements OnPanelListener {
  20.  
  21.        
  22.  
  23.         private Panel bottomPanel;
  24.  
  25.         private Panel topPanel;
  26.  
  27.         /** Called when the activity is first created. */
  28.  
  29.     @Override
  30.  
  31.  
  32.  
  33.     public void onCreate(Bundle savedInstanceState) {
  34.  
  35.         super.onCreate(savedInstanceState);
  36.  
  37.        
  38.  
  39.         setContentView(R.layout.main);
  40.  
  41.        
  42.  
  43.         Panel panel;
  44.  
  45.        
  46.  
  47.         topPanel = panel = (Panel) findViewById(R.id.topPanel);
  48.  
  49.         panel.setOnPanelListener(this);
  50.  
  51.         panel.setInterpolator(new BounceInterpolator(Type.OUT));
  52.  
  53.        
  54.  
  55.         bottomPanel = panel = (Panel) findViewById(R.id.bottomPanel);
  56.  
  57.         panel.setOnPanelListener(this);
  58.  
  59.         panel.setInterpolator(new BounceInterpolator(Type.OUT));
  60.  
  61.        
  62.  
  63.     }
  64.  
  65.  
  66.  
  67.         public void onPanelClosed(Panel panel) {
  68.  
  69.                 String panelName = getResources().getResourceEntryName(panel.getId());
  70.  
  71.                 Log.d("Test", "Panel [" + panelName + "] closed");
  72.  
  73.         }
  74.  
  75.         public void onPanelOpened(Panel panel) {
  76.  
  77.                 String panelName = getResources().getResourceEntryName(panel.getId());
  78.  
  79.                 Log.d("Test", "Panel [" + panelName + "] opened");
  80.  
  81.         }
  82.  
  83. }

How to do this? Or isn't this possible with

  1. setContentView(R.layout.main);

I now use the following code

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.         if(screenHeight > 1 && screenWidth > 1){
  2.  
  3.                // No Statusbar
  4.  
  5.             win.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);    
  6.  
  7.  
  8.  
  9.                // No Titlebar
  10.  
  11.                requestWindowFeature(Window.FEATURE_NO_TITLE);
  12.  
  13.                requestWindowFeature(Window.FEATURE_PROGRESS);  
  14.  
  15.         }

having the opposite problem actually ...

Postby 5tray » Tue May 05, 2009 12:34 am

I'm using a PreferenceActivity to show some preferences, however it seems by default the window title is removed for activities deriving from PreferenceActivity.

Any idea how to re-enable it?

rgd: having the opposite problem actually

Postby 5tray » Wed May 06, 2009 12:24 am

for the curious: i checked the android source for PreferenceActivity and verified the following:

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.     @Override
  2.  
  3.     protected void onCreate(Bundle savedInstanceState) {
  4.  
  5.         super.onCreate(savedInstanceState);
  6.  
  7.  
  8.  
  9.         requestWindowFeature(Window.FEATURE_NO_TITLE);
  10.  
  11.    
  12.  
  13.         setContentView(com.android.internal.R.layout.preference_list_content);
  14.  
  15.        
  16.  
  17.         mPreferenceManager = onCreatePreferenceManager();
  18.  
  19.         getListView().setScrollBarStyle(View.SCROLLBARS_INSIDE_INSET);
  20.  
  21.     }
  22.  
  23.  
Parsed in 0.036 seconds, using GeSHi 1.0.8.4


And according to the documentation once requestWindowFeature(...) is called for a particular feature, it cannot be undone ... so no title bar for concrete PreferenceActivity's ...

pls correct me if i'm wrong tho :)

For those of you who like to handle this within an xml file.

Within your theme description you define
Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1.  
  2.     <item name="android:windowNoTitle">true</item><!-- The Activity has no title -->
  3.  
  4.     <item name="android:windowFullscreen">true</item> <!-- Hides the Status Bar-->
  5.  
  6.  
Parsed in 0.001 seconds, using GeSHi 1.0.8.4


Within your manifest
Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1.  
  2.     <application android:label="@string/app_name"
  3.  
  4.                 android:theme="@style/MyTheme" > <!-- Loads your theme for the complete app -->
  5.  
  6. ...
  7.  
  8.     </application>
  9.  
  10.     <uses-permission android:name="android.permission.STATUS_BAR" /> <!-- necessary to manipulate the status bar-->
  11.  
  12.  
Parsed in 0.001 seconds, using GeSHi 1.0.8.4



This way you don't have to bother hiding the bar within every activity of your applicaiton

Re: Hide StatusBar/Title on QVGA - Getting Screen Resolution

Postby lewstherin » Wed Nov 17, 2010 6:12 am

This gave me all kinds of hell when I tried to do it on my tablet (ZT-180). To save other folks from the trouble, here is the solution.

1) If you follow the above steps correctly, you should see the status message overlapping with a portion of the app you are building. This means you are on the right track.
2) Check your tablet and see if an app called Spare Parts is installed. If it is not install it. It is available on the market.
3) It should have a setting called compatibility mode. If it is off, turn it on and reboot.
4) Once it is on, turn it off and reboot again.
5) Now, the status bar should get hidden when you go to your app.

This may not be relevant for most folks but thought I would share anyway.

Cheers,
ltt.
