This article describes the use of the Android Data binding technology, combined with the Watercress movie Search API, to display a list of movies in Recycleview.

2) Android Chromium WebView Principle Analysis Series

Android offers webview based on the chromium implementation from 4.4. Previously WebView was based on WebKit implementations. WebKit provides basic functions such as Web page parsing, layout and plotting, and JS running. Chromium provides infrastructure for WebView process, threading, and rendering on a webkit basis.

In the custom viewgroup, many effects include the user's finger to drag a view inside it (eg: slide-off menu, etc.), to write about the specific needs of onintercepttouchevent and ontouchevent These two methods is a very difficult thing, Need to deal with: multi-finger processing, acceleration detection and so on. Fortunately, the official support package in V4 provides viewdraghelper such a class to help us write custom ViewGroup conveniently.

4) What new technologies are available for Android development?

A discussion about new technologies for Android development that comes in.

5) The process of analyzing view drawing from the Viewrootimpl class

We know that the Phoneview object in activity helped us create a top-level view of the Phoneview inner class Decorview (the parent class framelayout) window. The XML content layout is then parsed into the view tree structure by Layoutinflater and added to the Decorview top-level view of the Framelayout parent container with the ID content. Here we already know that the content layout of the activity will eventually be added to the top-level view of the Decorview window, and I believe many people will wonder: How does the top-level view of the window Decorview on our mobile screen? This blog is an attempt to analyze Decorview's drawing process.

iOS Development 1) Jspatch implementation Principles < two >

From the last time I wrote

2) Ways and tools to improve iOS development efficiency

This article focuses on some of the methods and tools that I used in iOS development to improve development efficiency.

3) in-depth understanding of OBJECTIVE-C 2.0 Category

No matter how perfect the design of a class is, it is possible to encounter some unpredictable situations in future requirements evolution. So how do you extend an existing class? Generally, inheritance and composition are good choices. However, in Objective-c 2.0, the language features of category are provided, and new behaviors can be added dynamically for existing classes. The category is now ubiquitous across the Objective-c code, from Apple's official framework to open source frameworks, from large, complex apps to simple applications, catagory everywhere. This article has made a more comprehensive arrangement for the category, hoping to benefit the readers.

4) Concurrent memory allocation in the OBJECTIVE-C runtime

The runtime mechanism of OBJECTIVE-C is the core of Mac and iOS programs, and the Objc_msgsend function is the core of runtime, and the core of this function is the method cache. Today, we will show you how Apple is adjusting and allocating the memory used by the method cache in a way that is thread-safe and does not affect program performance, and the technology used may have never been used in other thread-safe materials.

5) IOS 9 split-screen multitasking: Getting Started (Chinese version)

This is a preliminary document for the API or development technology. Apple provides this information primarily to help you plan through the use of these technologies or programming interfaces with Apple products, which may change in the future, and the software mentioned in this article should be based on the final published operating system tests and final documentation. New versions of document information may be available in the future.
