1.Android端代码

private static final String LOGTAG = "MainActivity";
@SuppressLint("JavascriptInterface")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

final WebView myWebView = (WebView) findViewById(R.id.myWebView);

WebSettings settings = myWebView.getSettings();
settings.setJavaScriptEnabled(true);//设置JS可用
myWebView.addJavascriptInterface(new JsInteration(), "control");//传递对象进行交互
myWebView.setWebChromeClient(new WebChromeClient() {});
