Android- mailto链接无效
作者：互联网
我在stackoverflow上已经阅读了很多关于这个主题的问题,我的解决方案也来自这里,但它不起作用.此外,没有错误消息.
我在Android和一个主页上有一个webview,有一些mailto链接,当我尝试在mailclient中从我的webview打开mailto链接时,webview总是像普通网页一样打开邮件地址.
有人可以看看我的代码并告诉我的错误吗？
谢谢你的帮助.

编辑：
如果我尝试这个,我得到错误消息“方法replaseFirst(String)未定义类型字符串”.因此我将url.replaseFirst更改为url.replaceFirst,但他需要一个有争议的参数,所以我必须写url.replaceFirst(“mailto：”,X);.对于X,我可以键入mail,url或null.我尝试了每个人,每个人都得到消息,我必须添加一个return语句,所以我用return false做了.
现在我有这个代码：
public class MyWebViewClient extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.startsWith("mailto:")) {
String mail = url.replaceFirst ("mailto:", mail);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL, mail );
startActivity(Intent.createChooser(intent, "Send Email"));
}
return false;
}
}
这不起作用.所以我尝试了intent.setType(“message / rfc822”);而不是intent.setType(“text / plain”);但这也行不通.
我做错了什么？
EDIT2：
新代码：
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.startsWith("mailto:")) {
String mail = url.replaceFirst("mailto:", "");
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, mail );
startActivity(Intent.createChooser(intent, "Send Email"));
}
else if(url.startsWith("http:") || url.startsWith("https:")) {
view.loadUrl(url);
}
return true;
}
解决方法:
要强制打开邮件客户端,您可以尝试：
if(url.startsWith("mailto:")) {
String mail = url.replaceFirst("mailto:", "");
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, mail );
// intent.putExtra(Intent.EXTRA_SUBJECT, "Subject"); // if you want extra
// intent.putExtra(Intent.EXTRA_TEXT, "I'm email body."); // if you want extra
startActivity(Intent.createChooser(intent, "Send Email"));
} else if ... {
// your code as is
}
但其他“发送”应用也是开放的,取决于Intent.ACTION_SEND的支持
而不是intent.setType(“text / plain”); here建议使用intent.setType(“message / rfc822”);但我从未测试过.
编辑：
更改main.java的行：
// ...
WebView myWebView = (WebView) findViewById (R.id.webView1);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new MyWebViewClient()); // you name your class MyWebViewClient not WebViewClient
myWebView.loadUrl("WEBSITE"); // also change line order
// ...
