android 仿iphoneX上滑退出应用动画(二)
上文android 仿iphoneX上滑退出应用动画(一)已经说了思路和解决思想，这里对代码进行实现。
先明确，锁屏界面，通知栏和工具栏下滑界面是不需要滑动条的，launcher界面需要一个透明的滑动条，其他界面根据背景色确定需要白色还是黑色的滑动条。
监听到广播top_activity_changes，说明activity有变化
// add by csc for slide
if(topAppPackageName!=null){
if(!isInLockScreen())
addOrRemoveSlideView(true);
if(topAppPackageName.equals("com.mediatek.oobe")&&!topAppClassName.equals("com.mediatek.oobe.basic.OobeLockScreenActivity")){
addOrRemoveSlideView(false);
}
if(!topAppClassName.equals("com.android.systemui.recents.RecentsActivity"))
isOpenRecents = false;
}
// add by csc for slidepublic void setPanelExpanded(boolean isExpanded) {
if(DEBUG)Log.i("notification_panel","PhoneStatusBar setPanelExpanded() isExpanded="+isExpanded);
mStatusBarWindowManager.setPanelExpanded(isExpanded);
if (isExpanded && getBarState() != StatusBarState.KEYGUARD) {
if (DEBUG) {
Log.v(TAG, "clearing notification effects from setPanelExpanded");
}
clearNotificationEffects();
}
if (!isExpanded) {
removeRemoteInputEntriesKeptUntilCollapsed();
mNotificationsDislpayLayout.resetView();//added by xss for ios11
if(getBarState() == StatusBarState.KEYGUARD)unLockScreen();//added by xss for ios11 face unlock
}
//showOrHideNavigationBar(!isExpanded);//modified by xss for ios11 for NavigationBarView
addOrRemoveSlideView(!isExpanded);// add by csc for slide
}addOrRemoveSlideView方法的作用是add滑动条或者remove滑动条，其中用isAddSlideView判断是否已经存在滑动条，如果已经存在则不在添加
private void addOrRemoveSlideView(boolean isAdd){
