I have a view and view the site has malito code to send email.

I want that when I open the link opens Gmail app or another email application.

Thanks to all helpers.

public class teacher extends Activity implements OnClickListener {

WebView webView;

final Activity activity = this;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

this.getWindow().requestFeature(Window.FEATURE_PROGRESS);

setContentView(R.layout.teacher);

webView = (WebView) findViewById(R.id.webView145);

webView.getSettings().setJavaScriptEnabled(true); webView.loadUrl("https://dl.dropboxusercontent.com/u/233211/%D7%A8%D7%A9%D7%99%D7%95%D7%9F/iWebKit%20demo/ther.html");

webView.setWebChromeClient(new WebChromeClient() {

public void onProgressChanged(WebView view, int progress) {

activity.setTitle("Loading...");

activity.setProgress(progress * 100);

if (progress == 100)

activity.setTitle(R.string.app_name);

} });

webView.setWebViewClient(new WebViewClient() {

@Override

public void onReceivedError(WebView view, int errorCode,

String description, String failingUrl) {

// Handle the error

}

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

return true; } });}

public void onBackPressed() {

if (webView.canGoBack()) {

webView.goBack();

} else {

Intent B = new Intent(this, MainActivity.class);

startActivity(B);

}}

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (event.getAction() == KeyEvent.ACTION_DOWN) {

switch (keyCode) {

case KeyEvent.KEYCODE_BACK:

if (webView.canGoBack() == true) {

webView.goBack();

} else {

finish();

}return true;} }

return super.onKeyDown(keyCode, event);

}

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

}}

You have to create a subclass of WebViewClient and override mailto URL loading. Example:

public class MyWebViewClient extends WebViewClient {

private final WeakReference mActivityRef;

public MyWebViewClient(Activity activity) {

mActivityRef = new WeakReference(activity);

}

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

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

final Activity activity = mActivityRef.get();

if (activity != null) {

MailTo mt = MailTo.parse(url);

Intent i = newEmailIntent(activity, mt.getTo(), mt.getSubject(), mt.getBody(), mt.getCc());

activity.startActivity(i);

view.reload();

return true;

}

} else {

view.loadUrl(url);

}

return true;

}

private 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;

}

}

Then you have to set this custom WebViewClient to your WabView:

webView.setWebViewClient(new MyWebViewClient(activity);

回答2:

You should update your's WebViewClient with the following:

@SuppressWarnings("deprecation")

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

proceedUrl(view, Uri.parse(url))

return true;

}

@TargetApi(Build.VERSION_CODES.N)

@Override

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {

proceedUrl(view, request.getUrl());

return true;

}

private void proceedUrl(View view, Uri uri){

if (uri.toString().startsWith("mailto:")) {

startActivity(new Intent(Intent.ACTION_SENDTO, uri));

} else if (uri.toString().startsWith("tel:")) {

startActivity(new Intent(Intent.ACTION_DIAL, uri));

} else {

view.loadUrl(uri.toString());

}

}

回答3:

Note : - After Android Nougat shouldOverrideUrlLoading is Deprecated

You need to use shouldOverrideUrlLoading along with shouldOverrideUrlLoading for better support.

Also, you might want to check if URL have mailto: or tel:, which are used in HTML5 to trigger mail client and phone dial respectively.

A complete solution will look like this now

@SuppressWarnings("deprecation")

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

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

//Handle mail Urls

startActivity(new Intent(Intent.ACTION_SENDTO, Uri.parse(url)));

} else if (url.startsWith("tel:")) {

//Handle telephony Urls

startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));

} else {

view.loadUrl(url);

}

return true;

}

@TargetApi(Build.VERSION_CODES.N)

@Override

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {

final Uri uri = request.getUrl();

if (uri.toString().startsWith("mailto:")) {

//Handle mail Urls

startActivity(new Intent(Intent.ACTION_SENDTO, uri));

} else if (uri.toString().startsWith("tel:")) {

//Handle telephony Urls

startActivity(new Intent(Intent.ACTION_DIAL, uri));

} else {

//Handle Web Urls

view.loadUrl(uri.toString());

}

return true;

}
