我试图在我的应用程序中拦截嵌入式webview中的mailto：链接.我所拥有的工作正常,除非用户按下链接时返回应用程序时模糊.这是我在WebViewClient中所做的事情

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

if(url.startsWith("mailto:")){

url = url.replaceFirst("mailto:", "");

url = url.trim();

Intent i = new Intent(Intent.ACTION_SEND);

i.setType("plain/text").putExtra(Intent.EXTRA_EMAIL, new String[]{url});

context.startActivity(i);

return true;

}

context.findViewById(R.id.loadingBar).setVisibility(View.VISIBLE);

view.loadUrl(url);

return true;

}

如果我做一个view.reload()它确实解决了问题,但有没有更好的方法来修复它而不浪费带宽？我尝试了invalidate()但它没有用.

这是我正在谈论的一个例子

解决方法:

这是James Gray的答案的更强大版本.

它应该处理多个地址(以逗号分隔)和多个’cc’/’bcc’参数：

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

if (url == null) {

return false;

}

if (url.startsWith("market://")) {

view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));

return true;

}

if (url.startsWith("mailto:")) {

try {

List to = new ArrayList();

List cc = new ArrayList();

List bcc = new ArrayList();

String subject = null;

String body = null;

url = url.replaceFirst("mailto:", "");

String[] urlSections = url.split("&");

if (urlSections.length >= 2) {

to.addAll(Arrays.asList(urlSections[0].split(",")));

for (int i = 1; i < urlSections.length; i++) {

String urlSection = urlSections[i];

String[] keyValue = urlSection.split("=");

if (keyValue.length == 2) {

String key = keyValue[0];

String value = keyValue[1];

value = URLDecoder.decode(value, "UTF-8");

if (key.equals("cc")) {

cc.addAll(Arrays.asList(url.split(",")));

}

else if (key.equals("bcc")) {

bcc.addAll(Arrays.asList(url.split(",")));

}

else if (key.equals("subject")) {

subject = value;

}

else if (key.equals("body")) {

body = value;

}

}

}

}

else {

to.addAll(Arrays.asList(url.split(",")));

}

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);

emailIntent.setType("message/rfc822");

String[] dummyStringArray = new String[0]; // For list to array conversion

emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, to.toArray(dummyStringArray));

if (cc.size() > 0) {

emailIntent.putExtra(android.content.Intent.EXTRA_CC, cc.toArray(dummyStringArray));

}

if (bcc.size() > 0) {

emailIntent.putExtra(android.content.Intent.EXTRA_BCC, bcc.toArray(dummyStringArray));

}

if (subject != null) {

emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);

}

if (body != null) {

emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, body);

}

view.getContext().startActivity(emailIntent);

return true;

}

catch (UnsupportedEncodingException e) {

/* Won't happen*/

}

}

return false;

}
