Android：监听状态栏通知

Question

Is there a way to listen to the status bar notification when it is being pulled down?

Answer 1

1. For detecting status bar changes: you can register a listener to get notified of system UI visibility changes

So to register the listener in your activity:

// Detecting if the user swipe from the top down to the phone 
// screen to show up the status bar (without showing the notification area)

View decorView = getWindow().getDecorView();
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) {
                    // The system bars are visible.

                } else {
                    // The system bars are NOT visible.

                }
            }
        });

2. For detecting if the user pulls down the notification area of the status bar: override onWindowFocusChanged() in your activity

@Override
public void onWindowFocusChanged(boolean hasFocus) {

    if (hasFocus) { // hasFocus is true
        // the user pushed the notification bar back to the top
        Log.i("Tag", "Notification bar is pushed up");

    } else { // hasFocus is false
        // the user pulls down the notification bar
        Log.i("Tag", "Notification bar is pulled down");
    }
    super.onWindowFocusChanged(hasFocus);

}

Take a look on Notification.Builder setDeleteIntent (since api level 11).

There is also Notification deleteIntent (since api level 1)
