Android WebView is a very powerful control, this article mainly for its simple use and the author in the use of the problems encountered in doing some summary.This article references the blog post:http://blog.csdn.net/zgjxwl/article/details/9627685 First, Java and JavaScript interaction in WebView1. This is the injected interface class to interact with JS:

HTML page and JavaCodeThe combination method is generally used when the interface is often changed. You can say that HTML is placed in the network, and the software will access the network to obtain the latest interface as soon as it is opened. The disadvantage is that the access speed is slow due to the impact of network signals. 1. Use webview to display HTML code 2. Allow webview to execute

During Android development, it takes most of the time to create the interface, and only developers can make it by themselves. Therefore, I have been trying to use HTML5 + css3 to complete the process. phonegap is not quite mature yet, I am going to use Android native + webview to complete the process. I found that it is similar to flash as for mutual debugging. B

Mainactivity is as follows: Package CN. testjavascript; import android. OS. bundle; import android. webKit. webchromeclient; import android. webKit. webview; import android. app. activity;/*** demo Description: * JavaScript calls

Recently, in iOS projects, the interaction between oc and js needs to be used, and the implementation method must be the same as in Android to facilitate unified processing in js. So after studying the third-party library WebViewJavascriptBridge, we have implemented one following the interaction mechanism of WebView and JS in Android. we will share it with you he

Android Development, in addition to the use of the original eco-development approach, can also be developed using Java+html+javascript hybrid development, which can save a lot of development time, but also to enable users of different devices to obtain the same user experience. OK, no more nonsense, first come to see what to do today.The main is to achieve a simp

Run The example is an example of insert sorting. The main idea is to save the edited code in webview as an HTML file and load it with another webview. Directly add the code. First, add the following permissions to the manifest file: Layout file: Main activity: Package COM. example. webtest1; import Java. io. file; import Java. io. fileoutputstream; import Java. io. ioexception; import Java. io. input

With WebView, you can create interfaces between JavaScript code and the client's Android code. For example, Android can get input from JavaScript. To bind a new interface between your JavaScript and the

The following section describes how Android and JavaScript call each other. In this way, the UI is much simpler to design, and the UI can also be designed to be cross-platform. Now there are a lot of front-end web app frameworks, such as sencha and jquery mobile. We believe that with the development of Web apps in the future, we can also use HTML to design an interface that is as beautiful as a local applic
