Keep Screen Bright While In AsyncTask

问题

I'm using this code in my AsyncTask to make sure the screen stays bright while the AsyncTask runs:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

However, I don't want the screen to be forced to be bright after the AsyncTask has ran. How can I essentially 'undo' or 'turn off' that option?

回答1:

In your onPostExecute method in your AsyncTask call

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
