android：有没有办法在拉下状态栏时收听状态栏通知？

Answer 1

<强> 1。用于检测状态栏更改：您可以注册一个侦听器以获得有关系统UI可见性更改的通知

将以下代码放入您的活动

     // Detecting if the user swipe from the top down to the phone screen to show up the status bar
    // (without showing the notification area); so we could set mStatusBarShow flat to true to allow
    // us hide the status bar for the next onClick event
    boolean mStatusBarShown;
    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) {
                        // TODO: The system bars are visible. Make any desired
                        // adjustments to your UI, such as showing the action bar or
                        // other navigational controls.
                        mStatusBarShown = true;

                    } 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.
                        mStatusBarShown = false;

                    }
                }
            });

<强> 2。用于检测用户是否拉下状态栏的通知区域：覆盖活动中的onWindowFocusChanged（）

@Override
public void onWindowFocusChanged(boolean hasFocus) {

    // handle when the user pull down the notification bar where
    // (hasFocus will ='false') & if the user pushed the
    // notification bar back to the top, then (hasFocus will ='true')
    if (!hasFocus) {
        Log.i("Tag", "Notification bar is pulled down");
    } else {
        Log.i("Tag", "Notification bar is pushed up");
    }
    super.onWindowFocusChanged(hasFocus);

}

查看Notification.Builder setDeleteIntent（自api 11级以来）。
