Question

i was just wondering if there was a simple way to see if an application running on android is currently in full screen. is there a way to query android to see if you\'re cu

Answer 1

You can figure out if your Activity is running fullscreen via getWindow().getFlags().

However, if by "an application" you are referring to somebody else's application, then the answer is no.

Answer 2

you may use some thing like this;

findViewById(android.R.id.content).getHeight();
    getResources().getDisplayMetrics().heightPixels;

and check for equality; hope this helps;

Answer 3

As of api11 there is now a way to detect that using a View.setOnSystemUiVisibilityChangeListener

The listener interface documentation notes the following:

Interface definition for a callback to be invoked when the status bar changes visibility. This reports global changes to the system UI state, not what the application is requesting.

I don't know if there's a way to do it prior to Honeycomb.

Answer 4

if you want to Respond to UI visibility changes for all apps including yours, use this code

View decorView = getWindow().getDecorView();//you can also use findViewById to get the view
decorView.setOnSystemUiVisibilityChangeListener
        (new View.OnSystemUiVisibilityChangeListener() {
    @Override
    public void onSystemUiVisibilityChange(int visibility) {
        // Note that system bars will only be "visible" if none of the
        // LOW_PROFILE, HIDE_NAVIGATION, or FULLSCREEN flags are set.
        if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
            // TODO: The system bars are visible. Make any desired
            // adjustments to your UI, such as showing the action bar or
            // other navigational controls.
        } else {
            // TODO: The system bars are NOT visible. Make any desired
            // adjustments to your UI, such as hiding the action bar or
            // other navigational controls.
        }
    }
});
