[英]Opening tel: & mailto: links in Android WebViewClient
I have been looking for an answer to this question that I can understand for the last couple of days. 在过去的几天里,我一直在寻找一个我可以理解的问题的答案。 After trying all of the code snippets online that I have seen I am still having difficulties.
在网上尝试了所有代码片段后,我仍然遇到了困难。 I am very new to the android sdk and java, actually this is my first shot at writting an Android app.
我对android sdk和java非常陌生,实际上这是我编写Android应用程序的第一枪。 So my question is this, how come I keep getting the ever so famous error "Page cant be displayed" when clicking on a mailto or tel link ?
所以我的问题是,当单击mailto或tel链接时,为什么会一直收到如此著名的错误“页面无法显示”?
Here is my code: 这是我的代码:
package com.mine.mobile;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MineActivity extends Activity {
/** Called when the activity is first created. */
/**@Override */
WebView webview;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new WebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://my.mobilesite.com");
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
return true;
} else 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});
startActivity(i);
return true;
} else if (url.startsWith("geo:")) {
Intent searchAddress = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(searchAddress);
}
else {
view.loadUrl(url);
return true;
}
return true;
}
}
You put the method in your Activity. 您将方法放在“活动”中。 It needs to override the method in WebView.
它需要重写WebView中的方法。 For example:
例如:
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
...
}
} }
