我的WebView
加载了网页浏览中的所有链接 - 但是当我选择一个电子邮件链接时,它会尝试将其加载到网页浏览中,而不是在手机上启动电子邮件应用。我该如何解决?链接是mailto://someone@somewhere.com
这是我的代码 - WebView
本身正常工作,所有内容都在webview中加载,包括mailto:等。需要mailto链接加载到其他地方

private class myWebViewClient extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
if (url.startsWith("mailto:") || url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse(url));
startActivity(intent);
}
view.loadUrl(url);
return true;
}
}}

我假设您已经覆盖了shouldOverrideUrlLoading,您只需要处理这种特殊情况。
mWebClient = new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.startsWith("mailto:")){
MailTo mt = MailTo.parse(url);
Intent i = newEmailIntent(MyActivity.this, mt.getTo(), mt.getSubject(), mt.getBody(), mt.getCc());
startActivity(i);
view.reload();
return true;
}
else{
view.loadUrl(url);
}
return true;
}
};
mWebView.setWebViewClient(mWebClient);
public static Intent newEmailIntent(Context context, String address, String subject, String body, String cc) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { address });
intent.putExtra(Intent.EXTRA_TEXT, body);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_CC, cc);
intent.setType("message/rfc822");
return intent;
}

关于@schwiz提供的答案,这是一个更清洁的例子。假设WebView
名为webView
:
webView.setWebViewClient(new WebViewClient() {
// shouldOverrideUrlLoading makes this `WebView` the default handler for URLs inside the app, so that links are not kicked out to other apps.
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// Use an external email program if the link begins with "mailto:".
if (url.startsWith("mailto:")) {
// We use `ACTION_SENDTO` instead of `ACTION_SEND` so that only email programs are launched.
Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
// Parse the url and set it as the data for the `Intent`.
emailIntent.setData(Uri.parse(url));
// `FLAG_ACTIVITY_NEW_TASK` opens the email program in a new task instead as part of this application.
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Make it so.
startActivity(emailIntent);
return true;
} else {
// Returning false causes WebView to load the URL while preventing it from adding URL redirects to the WebView history.
return false;
}
}
});
我已使用所有mailto:
选项对此进行了测试:多个电子邮件地址,CC,BCC,主题和正文。
