I currently have a button in my application that changes the screen brightness, but when I leave that activity, it resets the screen brightness back to normal. I want it to set the brightness throughout the entire application, but go back to normal when I close the application.

This is the code I have now:

public void lower(View view) {
    WindowManager.LayoutParams lp = getWindow().getAttributes();
    float brightness = (float) 0.01;
    lp.screenBrightness = brightness;
    getWindow().setAttributes(lp);  
}

public void raise(View view) {
    WindowManager.LayoutParams lp = getWindow().getAttributes();
    float brightness = (float) -1;
    lp.screenBrightness = brightness;
    getWindow().setAttributes(lp);
}

I was thinking I might be able to do a sort of getScreenBrightness type method on the onCreate() method of my other activities, but this doesn't work.

Thanks for your time.

you will need to create separate class for accessing these two methods for all activites – ρяσѕρєя K Feb 16 '13 at 19:11
Ok. What do I need to add into this class? – Eichhörnchen Feb 16 '13 at 19:22

nothing more just move these methods in separate class and pass Activity context to it for setting Brightness when u call these methods for activities – ρяσѕρєя K Feb 16 '13 at 19:24
