众所周知,app的一些功能可能会使用到H5开发,这就难免会遇到java与js 的相互调用,android 利用WebViewJavascriptBridge 实现js和java的交互,这里介绍下JsBridge第三方库的使用。
github传送门:https://github.com/lzyzsd/JsBridge (本地下载)
简单分析
java与js相互调用如下:
java发送数据给js,js接收并回传给java
同理,js发送数据给java,java接收并回传给js
同时两套流程都存在「默认接收」 与 「指定接收」
大致调用流程图如下:
依赖
项目build.gradle
repositories {
// ...
maven { url "https://jitpack.io" }
} app build.gradle
dependencies {
compile 'com.github.lzyzsd:jsbridge:1.0.4'
} xml里直接使用com.github.lzyzsd.jsbridge.BridgeWebView替代原生WebView
另外放置两个Button用于测试使用
<?xml version="1.0" encoding="utf-8"?>
html文件里简单放置两按钮发送数据,同时提供打印信息
Title
js发送给java默认接收
js发送给java指定接收
打印信息
这里我本地跑的一个简单的django项目,起了个服务供使用
webView.loadUrl(http://10.0.0.142:8000/cake/jsbridge); webview加载页面
java发送数据给js
button注册监听
javaToJsDefault.setOnClickListener(this);
javaToJsSpec.setOnClickListener(this); 按钮点击事件,java传递数据给js
//java传递数据给js
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.java_to_js_default:
//默认接收
webView.send("发送数据给js默认接收", new CallBackFunction() {
@Override
public void onCallBack(String data) { //处理js回传的数据
Toast.makeText(WebTestActivity.this, data, Toast.LENGTH_LONG).show();
}
});
break;
case R.id.java_to_js_spec:
//指定接收参数 functionInJs
webView.callHandler("functionInJs", "发送数据给js指定接收", new CallBackFunction() {
@Override
public void onCallBack(String data) { //处理js回传的数据
Toast.makeText(WebTestActivity.this, data, Toast.LENGTH_LONG).show();
}
});
break;
default:
break;
}
} js WebViewJavascriptBridge注册事件监听,接收数据
