如何获取WebView中单击区域的SVG地图ID
单击SVG特定区域时，我试图显示一个对话框。该ID存储在SVG的路径中。
点击区域检索ID。
如何从路径获取ID。
<path
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); stroke-opacity: 1; opacity: 0.7;"
d="M925,0L937,94L894,98L906,200L1651,261L1667,63L925,0Z"
fill="#ff9c00"
id="1"
stroke="#c86400"
stroke-opacity="1"
stroke-width="2">
</path>
ID在路径中。

在我要获取该区域ID的区域上单击时，我的需求ID。
我这样实现WebView
WebSettings setting = wv.getSettings();
setting.setBuiltInZoomControls(true);
setting.setSupportZoom(true);
setting.setUseWideViewPort(true);
setting.setLoadWithOverviewMode(true);
setting.setJavaScriptEnabled(true);
String url="http://192.168.1.3:8011/map/1";
wv.loadUrl(url);
wv.setWebViewClient(new WebViewController());
WebViewController类
public class WebViewController extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
Log.e("New Url",url);
return true;
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
Log.e("New Url",url);
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
Log.e("New Url",url);
}
}
请帮助我弄清楚我的代码出了什么问题。
任何帮助将不胜感激。

您必须通过从自己制作一个html并将其放在资产文件夹中来实现这一目标 并像这样加载您的特定svg
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('object').on("click", function(){
jsondata.returnPathId($(this).attr('id'));
});
});
function loadURL(url){
$('#main').html('<object data="'+url+'" type="image/svg+xml">');
}
</script>
</head>
<body>
<div id="main">
</div>
</div>
</body>
</html>
并从您的webview加载它，并使用JavascriptInterface这样
void loadatainWebview() {
try {
stepView.setStepSize(mList.size());
WebSettings settings = webview.getSettings();
settings.setJavaScriptEnabled(true);
settings.setEnableSmoothTransition(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setSupportZoom(false);
settings.setBuiltInZoomControls(false);
settings.setAppCacheEnabled(true);
webview.setWebChromeClient(new WebChromeClient() {
@Override
public void onExceededDatabaseQuota(String url, String databaseIdentifier, long currentQuota, long estimatedSize, long totalUsedQuota, WebStorage.QuotaUpdater quotaUpdater) {
quotaUpdater.updateQuota(estimatedSize * 2); // try to keep quota size as big as possible else database will not get created in HTML 5 app
}
});
webview.setWebViewClient(new WebViewClient());
webview.addJavascriptInterface(new JavaScriptInterface(getApplicationContext()), "jsondata");
webview.loadUrl("file:///android_asset/index.html");
loadsvgUrl();
} catch (Exception e) {
}
}
void loadsvgUrl(){
String url="http://192.168.1.3:8011/map/1";
webview.loadUrl("javascript:loadURL(url)");
}
public class JavaScriptInterface {
Context mContext;
JavaScriptInterface(Context c) {
mContext = c;
}
@JavascriptInterface // must be added for API 17 or higher
public String returnPathId(String id) {
Log.e("Your Path ID",String.valueOf(id));
}
