Android WebView image view

1. Call the following method in onPageFinished of WebViewClient

private void addImageClickListener(WebView webView) {
        webView.loadUrl("javascript:(function(){" +
                "var objs = document.getElementsByTagName(\"img\"); " +
                "var imgsxx = new Array(objs.length);" +
                "for(var i=0;i<objs.length;i++)  " +
                "{"
                + "    imgsxx[i]=objs[i].src;"
                + "     var position=i;"
                + "    objs[i].onclick=function()  " +
                "    {  "
                + " window.imageListener.open(imgsxx,this.src); " +//Find the code block labeled img through js code, set the click listener method to connect with the local openImage method
                "    }  " +
                "}" +
                "})()");
    }

2. Define the JS interactive interface MJavascriptInterface

public class MJavascriptInterface {

    private Activity mActivity;

    public MJavascriptInterface(Activity activity) {
        mActivity = activity;
    }


    /**
     *
     * @param imgs
     * @param img
     */
    @android.webkit.JavascriptInterface
    public void open(final String[] imgs, final String img) {

    }

}

3. WebView settings

WebSettings webSettings = getSettings ();
        webSettings.setUserAgentString (webSettings.getUserAgentString ());
        webSettings.setJavaScriptEnabled(true); // Set webview to support JavaScript
        addJavascriptInterface(new MJavascriptInterface((Activity) getContext()), "imageListener");
        webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
