ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
return (netInfo != null && netInfo.isConnected());
}
}
任何解决方案吗?
推荐答案
如果链接包含地理位置，电话号码和电子邮件地址，则可以使用以下代码切换到搜索屏幕和邮件客户端.
If the links contain geographic locations, phone numbers, and email addresses, you can switch to the search screen and mail client using the code below.
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
startActivity(intent);
view.reload();
return true;
} else if (url.contains("mailto:")) {
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
} else if(url.contains("geo:")) {
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse(url)));
return true;
} else {
view.loadUrl(url);
return true;
}
}
