在android中从webview获取图像src

<WebView
    android:id="@+id/webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
/>

WebView webView = findViewById(R.id.webview);
webView.setWebViewClient(new WebViewClient());

webView.loadUrl("https://www.example.com");

webView.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageFinished(WebView view, String url) {
        // 页面加载完成后获取图像src
        String javascript = "javascript:window.android.onImageSrcObtained(document.getElementsByTagName('img')[0].src);";
        webView.evaluateJavascript(javascript, null);
    }
});

window.android = {
    onImageSrcObtained: function(src) {
        // 将获取到的图像src传递给Android端
        Android.onImageSrcObtained(src);
    }
};

@JavascriptInterface
public void onImageSrcObtained(String src) {
    // 在这里处理获取到的图像src
    Log.d("ImageSrc", src);
}
