Android Webview ERR_UNKNOWN_URL_SCHEME错误 [英] Android Webview ERR_UNKNOWN_URL_SCHEME Error

问题描述

当我单击链接到mailto:[e-mail]时，出现此错误:

When I click a link which goes to mailto:[e-mail] I get this error:

网络:ERR_UNKNOWN_URL_SCHEME

net: ERR_UNKNOWN_URL_SCHEME

我试图添加一个if(url.startsWith("mailto:"))条件，但是它不起作用.

I tried to add an if(url.startsWith("mailto:")) condition but it's not working.

这是我的MyWebViewClient方法:

public class MyWebViewClient extends WebViewClient {

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {

        }

        @Override
        public void onPageFinished(WebView view, String url) {
            view.setVisibility(View.VISIBLE);
            final Animation fade = new AlphaAnimation(0.0f, 1.0f);
            fade.setDuration(200);
            view.startAnimation(fade);
            view.setVisibility(View.VISIBLE);

        }

    }
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if(url.startsWith("mailto:")){
            Intent intent = null;
            try {
                intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);
            } catch (URISyntaxException e) {
                e.printStackTrace();
            }
            view.getContext().startActivity(intent);
        }
        else if (url.endsWith(".mp3")) {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse(url), "audio/*");
            startActivity(intent);

        } else if (url.endsWith(".mp4") || url.endsWith(".3gp")) {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse(url), "video/*");
            startActivity(intent);
        }
        else {
            return false;
        }
        view.reload();
        return true;
    }

这就是我将功能添加到loadUrl之前的Web视图中的方式:

and this is how I add the function to my web view before loadUrl:

...
mWebview.setWebViewClient(new MyWebViewClient());
...

推荐答案

尝试一下

if(url.startsWith("mailto:")){
        MailTo mt = MailTo.parse(url);
        Intent i = new Intent(Intent.ACTION_SEND);
        i.setType("text/plain");
        i.putExtra(Intent.EXTRA_EMAIL, new String[]{mt.getTo()});
        i.putExtra(Intent.EXTRA_SUBJECT, mt.getSubject());
        i.putExtra(Intent.EXTRA_CC, mt.getCc());
        i.putExtra(Intent.EXTRA_TEXT, mt.getBody());
        mContext.startActivity(i);
        view.reload();
        return true;
    }
