class JsObject {

@JavascriptInterface

public String toString() { return "injectedObject"; }

}

webView.addJavascriptInterface(new JsObject(), "injectedObjectOfWoxue");

webView.setWebChromeClient(new WebChromeClient()); //设置webchromeclinet 之后 alter 才会起作用

js端

function toString()

var b=window.injectedObjectOfWoxue.toString();

alert(b);

解决：

runOnUiThread(newRunnable(){@Overridepublicvoidrun(){// Code for WebView goes here}});
