Android Web 视图 shouldOverrideUrlLoading() 已弃用.(替代) [英] Android Web-View shouldOverrideUrlLoading() Deprecated.(Alternative)

问题描述

我找到了一种使邮件在 android webview 中工作的方法，但该方法已被弃用.谁能给我新方法的完整代码片段.这是我在这个网站上找到的方法

Java 代码如下:

@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {如果(url.startsWith(电话:")){发起呼叫(网址)；返回真；}if (url.startsWith("mailto:")) {sendEmail(url.substring(7));返回真；}返回假；}

但是当我的目标平台为 Android 7.1.1 时它不起作用

解决方案

Android N 及以上版本有此方法签名:

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)

<块引用>

所有Android版本都支持的那个有这个方法签名:

public boolean shouldOverrideUrlLoading(WebView view, String url)

<块引用>

我应该怎么做才能使其适用于所有版本?

你需要覆盖这两个方法

对于包括 Android N+ 在内的每个 api，您都需要更改代码.

检查下面的代码.它将针对 N 和更高版本的 API

@SuppressWarnings("deprecation")@覆盖public boolean shouldOverrideUrlLoading(WebView view, String url) {如果(url.startsWith(电话:")){发起呼叫(网址)；返回真；}if (url.startsWith("mailto:")) {sendEmail(url.substring(7));返回真；}返回假；}@RequiresApi(Build.VERSION_CODES.N)@覆盖public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {String url = request.getUrl().toString();如果(url.startsWith(电话:")){发起呼叫(网址)；返回真；}if (url.startsWith("mailto:")) {sendEmail(url.substring(7));返回真；}返回假；}

I have Found a method to make mailto work in android webview but the method is deprecated.Can any one give me full code snippet of the new method. Here is the method I found on this site

Java code is below:

@Override
   public boolean shouldOverrideUrlLoading(WebView view, String url) {

     if (url.startsWith("tel:")) {
         initiateCall(url);
         return true;
      }
       if (url.startsWith("mailto:")) {
         sendEmail(url.substring(7));
         return true;
      }
         return false;
  }

But it's not working when I have target platform as Android 7.1.1

解决方案

Android N and above has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)

The one that is supported by all Android versions has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, String url)

What should I do to make it work on all versions?

you need to override both the methods

For every api including Android N+ you need to change your code.

Check this below code. It will target both lower API with N and above

@SuppressWarnings("deprecation")
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if (url.startsWith("tel:")) {
        initiateCall(url);
        return true;
    }
    if (url.startsWith("mailto:")) {
        sendEmail(url.substring(7));
        return true;
    }
    return false;
}

@RequiresApi(Build.VERSION_CODES.N)
@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
    String url = request.getUrl().toString();
    if (url.startsWith("tel:")) {
        initiateCall(url);
        return true;
    }
    if (url.startsWith("mailto:")) {
        sendEmail(url.substring(7));
        return true;
    }
    return false;
}
