2、明 WindowManager 对象以及其他参数对象privateWindowManager privateView privateWindowManager.LayoutParams 2、在 onCreate wm= (WindowManager) 3、在类中定义 myToast publicpublicvoid myToast(String address) intwhich = sp.getInt(which, intits =new int R.drawable.call_locate_orange, R.drawable.call_locate_blue, R.drawable.ca

10、y; try catch(InterruptedExceptione) 在上面的代码中，我们给 ImageView 控件设置了动画背景资源。在 drawable 目录下创建 rocket.xml，?xmlversion=1.0encoding=utf-animation-listxmlns:android= HYPERLINK /apk/res/android /apk/res/android 上面的动画的 android:oneshot=false创建快捷方式创建快捷方式就是在系统桌面创建一个图标，点击该图标会执行一段操作，比如打开某个原因，拨打电话、发送我们在我们的手机卫士项目的 SplashActivity privatevoid createShortCut() sp= getSharedPreferences(config, booleaninstalled=sp.getBoolean(shortcutInstalled, if(!installed) Intent intent = new Intent(); BitmapFactory.decodeResource(getResources(),intent.putExtra(Intent.EXTRA_SHORTCUT_NAME手机卫士Intent call
