WebView Android中未以HTML格式加载图像

Question

Have created a functionality when user clicks on the image thumbnail, the main image will load by calling on the WebView.loadurl(String.format()) method, the selected image will then be uploaded and displayed for the user to view. However, in this instances, when user clicks on the image thumbnail, the following message is displayed:

The requested URL /projectname_uat/data/images/property/property_id/360/1/index.htm is not found on this server.

What has gone wrong in that instances?

Furthermore, when I copied the following url into a web browser: Google Chrome, it wasn't showing initially, however when I made the following changes, the images was showing in the web browser but not on the app device. What I do understand is that there is no difference between htm or html, and most the images that can be displayed are either in htm or html.

the following change that I have made, which is to change htm to html:

/projectname_uat/data/images/property/property_id/360/1/index. html

Could anyone offer any assistance to this issue?? It has been bogging my mind for a couple of days and it is getting frustrating. Thanks in advance.

Code:

int img_id = 1;
photoPb = (ProgressBar) findViewById(R.id.photoPb);
    photoPb.setVisibility(View.INVISIBLE);
    webView = (WebView) findViewById(R.id.webview01);
    webView.getSettings().setJavaScriptEnabled(true);
    //webView.getSettings().setPluginsEnabled(true);
    webView.getSettings().setPluginState(PluginState.ON);
    webView.setVerticalScrollBarEnabled(false);
    webView.setHorizontalScrollBarEnabled(false);
    webView.setWebViewClient(new WebViewClient() {
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(getContext(), description, Toast.LENGTH_SHORT).show();
        }
    });
 if (panoSize > 0) {
        g = (Gallery) findViewById(R.id.gallery01);
        g.setAdapter(new ImageAdapter());
        int pad = 15;
        g.setSpacing(1);
        g.setUnselectedAlpha(255);
        g.setPadding(pad, 10, pad, pad);
        g.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                img_id = position;
                setImageShade(position);
                captionText.setText(caption[position]);
                Log.i("PropertyPanoramaActvity:if(panoSize>0)","******webView.loadUrl******"+getString(R.string.app_360_domain)+getString(R.string.app_360_property)+(getIntent().getIntExtra("propertyId", 0))+getString(R.string.app_360_directory)+(img_id)+getString(R.string.app_360_index));
                //webView.loadUrl(String.format("https://developer.dapoltd.com/spacetobe_uat/data/images/property/property107/360/4/index.htm", id, img_id));
                webView.loadUrl(String.format(getString(R.string.app_360_domain)+getString(R.string.app_360_property)+(getIntent().getIntExtra("propertyId", 0))+getString(R.string.app_360_directory)+(img_id)+getString(R.string.app_360_index)));


            }
        });
    }

String.XML:

<string name="app_360_domain">https://developer.dapoltd.com/spacetobe_uat/</string>
<string name="app_360_property">data/images/property/property</string>
<string name="app_360_directory">/360/</string>
<string name="app_360_index">/index.htm</string>

Answer 1

您没有将app_360_index字符串值更改为/index.html

Answer 2

尝试使用：

webView.loadUrl( ""+getString(R.string.app_360_domain)+getString(R.string.app_360_property)+(getIntent().getIntExtra("propertyId", 0))+getString(R.string.app_360_directory)+(img_id++)+getString(R.string.app_360_index));

Answer 3

It is really hard to say why it is not showing image, but what I think now is the problem me be in back slashes. Try this:

1)

String urlToLoad = String.format(getString(R.string.app_360_domain) + getString(R.string.app_360_property)+(getIntent().getIntExtra("propertyId", 0))+getString(R.string.app_360_directory)+(img_id)+getString(R.string.app_360_index);

2) Then go to debug, and check urlToLoad value if it is opened in browser. 3) If not '@' must be added at the start of url in order compiler understood that backslash is part of the url, not escape sign
