【问题描述】：

我想在我的应用程序（如 GMail）的 web 视图中显示 PopupMenu。

这是我的代码：

webView.addjavascriptInterface(new WebAppInterface(getActivity()), "ScriptToandroid");

<div class="moreover_icon" onclick="showPopup('file_attach_path', event)">
    <img class="overflow_icon" src="android_moreover_icon"/>
</div>

<script type="text/javascript">

    function showPopup(file_path, event) 
        ScriptToAndroid.showPopupDialog(file_path, pos_x, pos_y);
    
</script>

@JavascriptInterface
public void showPopupDialog(String filePath, int x, int y) 
    //show PopupMenu

有人需要回答吗？

【参考方案1】：

使用 WebViewClient

mWebView = (WebView) findViewById(R.id.webView);
mWebView.setWebViewClient(new WebClient(this));

拦截 shouldOverrideUrlLoading()

public class WebClient extends WebViewClient 

    MainActivity mainActivity;
    public WebClient(MainActivity activity) 
        mainActivity = activity;
    

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) 
        if(url.contains("xxx")) 
            Log.i("show pop", "xx");
        
        return false;
    

    @Override
    public boolean shouldOverrideKeyEvent(WebView view, KeyEvent event) 
        return super.shouldOverrideKeyEvent(view, event);
    

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) 
        super.onPageStarted(view, url, favicon);
    

    @Override
    public void onPageFinished(WebView view, String url)

他们是如何创建附件视图的，我的意思是他们使用的是自定义 html 布局？
