android multi window mode

Android Development Series (26): Use PopupWindow to create a dialog box style window Creating a dialog box style window is simple and requires the following steps: 1. Call the PopupWindow constructor to create a PopupWindow object. 2. Call showAsDropDown (View v) of PopupWindow to display it as the drop-down component of the v component: or call the showAtLocatio

The singleton mode, which can be said to be the simplest of the 23 design patterns of GOF.This mode is relatively independent compared to several other modes, it is only responsible for the control of their own number of instantiations of a single (rather than consider the user to produce what kind of instance), very interesting, is a feeling very clean mode, I l

combination, a large number of subclasses will be generated, resulting in explosive growth of the number of subclasses. // Another possible cause is that the class definition is hidden, or the class definition cannot be used to generate a subclass. DecoratorImp d = new DecoratorImp (); d. SetComponent (dp); Log. I (TAG, d. getName ());}} In the Android framework, the decoration mode is also widely used; I

other system core services that carry the burden of interacting with the client program throughout the Android system.NO5:A simple summary of Setcontentview 's basic process is the following steps:1) Building the Mdecor object, Mdecor is the top-level view of the entire window, it mainly contains the Titile and content view two areas, the title area is our title bar, the content view area is to display the

window is an abstract class, the implementation class is PhonewindowNo12:CreateView is relatively simple, if there is a prefix, then constructs the full path of the view, loads the class into the virtual machine, obtains the constructor of the class and caches it, creates the view object through the constructor, and finally returns the View object, which is The process of parsing a single view . After parsing the rinflate, the entire tree of views i

Android design mode-singleton Mode Design Patterns are some of the experiences accumulated by our predecessors during the development process. During the development process, we apply appropriate design patterns based on actual conditions to make the program structure simpler, it is conducive to program expansion and maintenance, but it is not difficult to use a

By applebomb [csdn] ver: 09-04-18 The current development method is to use Remote Load pages to achieve multi-page effects, similar to the 126 mailbox multi-tab effect. But it is better than 126 mailbox, because the page is loaded to the local, 126 seems to be re-requested. In the near future, this development method has basically matured and accumulated some experience to share and discuss with developers

Read Xu Jing Week wrote a "program interface multi-mode display implementation", the program has multiple display modes in one application, but the interface is implemented by the SDI MFC document view structure, but the code used is not implemented in MDI's multiple documents/views, and through MSDN I found some implementations of MDI Multi-

Update the window information If the window activity itself does not actively update the information, when there is new information need to update the activity interface, because on the above we set the SingleInstance boot mode, so we need to overwrite onnewintent (Intent Intent) method,

will find the corresponding images in these folders according to the machine resolution. To be compatible with different screens on different platforms during development, we can crop the image with a aspect ratio, make sure there is sufficient resolution, and put it in the corresponding directory. For example, if we want to set the background of our application window, we can simply crop the corresponding image using the specifications mentioned ab

Android development skills-imitation of the new version of QQ screen lock pop-up window The new version of qq can display qq messages in the pop-up window under the screen lock. This function is also required for projects currently in progress. After a variety of experiments and data searches, the process is finally achieved, but there are some points to note. Th

The design pattern is the predecessor in the development process summarizes some experience, we in the development process according to the actual situation, applies the suitable design pattern, may make the program structure more simple, facilitates the program the extension and the maintenance, but also is not does not use the design pattern the procedure is not good, if the simple procedure does not have, has the kind of superfluous feeling.Singleton mode
