并没有具体的onclick事件，怎么办呢？

1、首先在Chrome上写了端测试代码，测试没问题

var child=document.getElementsByTagName('a')[0];

child.οnclick=function(){

userIdClick();

};

function userIdClick(){

myObj.getClose();

};

2、然后使用安卓端注入进来

webview.getSettings().setJavaScriptEnabled(true);

webview.addJavascriptInterface(new JSObject(), "myObj");

webview.setWebViewClient(new WebViewClient() {

public boolean shouldOverrideUrlLoading(WebView view, String url) {

Toast.makeText(MainActivity.this, "wodo-7-", Toast.LENGTH_SHORT).show();

view.loadUrl(url);

return true;

}

@Override

public void onPageFinished(WebView view, String url) {

super.onPageFinished(view, url);

String  js = "var script = document.createElement('script');";

js+= "script.type = 'text/javascript';";

js+="var child=document.getElementsByTagName('a')[0];";

js+="child.οnclick=function(){userIdClick();};";

js+= "function userIdClick(){myObj.getClose();};";

webview.loadUrl("javascript:" + js);

}

});

class JSObject {

@JavascriptInterface

// sdk17版本以上加上注解

public String getData(String txt) {

return "12345678";

}

@JavascriptInterface

// sdk17版本以上加上注解

public void getClose() {

Toast.makeText(MainActivity.this, "dododo", Toast.LENGTH_SHORT)

.show();

// finish();

}

}

这样就可以实现点击调用本地方法了。

二、如果想获取html中某个内容

@Override

public void onPageFinished(WebView view, String url) {

super.onPageFinished(view, url);

String  js = "var script = document.createElement('script');";

js+= "script.type = 'text/javascript';";

js+="var child=document.getElementsByTagName('a')[0];";

js+="child.οnclick=function(){userIdClick();};";

js+= "function userIdClick(){myObj.getClose();};";

webview.loadUrl("javascript:" + js);

//view.loadUrl("javascript:window.myObj.showSource(document.getElementsByTagName('p')[1].innerHTML);");

view.loadUrl("javascript:myObj.showSource(document.getElementsByTagName('p')[0].innerHTML);");   //关键代码

}

});

/**

* @author jiangwei1-g

*/

class JSObject {

@JavascriptInterface

// sdk17版本以上加上注解

public String getData(String txt) {

return "12345678";

}

@JavascriptInterface

// sdk17版本以上加上注解

public void getClose() {

Toast.makeText(MainActivity.this, "dododo", Toast.LENGTH_SHORT).show();

}

@JavascriptInterface

// sdk17版本以上加上注解

public void showSource(String html) { //关键代码

Toast.makeText(MainActivity.this, html, Toast.LENGTH_SHORT).show();

System.out.println("====>html="+html);

}

}
