Question

i create a lockscreen application and i need to disable a home button, so if that phone is stolen, that phone can’t be accessed.. my lockscreen is a fullscreen activity.. im use this code to disable a home button, but it gave me some bug. here’s the code:

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    }

    @Override
    public void onAttachedToWindow()
    {  
        this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);     
        super.onAttachedToWindow();  
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        return false;
    }

that code gave me some bug like a notification/status area still can be accessed even my activity on the full screen mode, if i turn off my display and turn on it again.. the bug is like this :

first time application started: (still no problem)

after i turn off my screen from power button and turn it on again:

the main problem is on the lockscreen.. when the notification area still can be accessed, then the lockscreen is not useful..

any idea how to solve this?? please help..

I am also facing the same problem when i press the end key button.

For my phone TYPE_KEYGUARD seems to override the fullscreen, no titlebar theme. The notification bar is always present. Try this:

@Override
public void onAttachedToWindow()
{  
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);     
    super.onAttachedToWindow();  
}

Make your view stretch the entire screen and it will cover up the notification area. Your notification area may still be clickable (invisibly) but I believe if you catch all the key events on your view it should not propagate down to the bar.
