I want to use webview to load the image,these is my code:

mWebView = (WebView) findViewById(R.id.webview);
    // 设置字符集编码
    mWebView.getSettings().setDefaultTextEncodingName("UTF-8");
    mWebView.getSettings().setLayoutAlgorithm(
            LayoutAlgorithm.SINGLE_COLUMN);
    mWebView.getSettings().setBlockNetworkImage(false);
     mWebView.getSettings().setJavaScriptEnabled(true);
     mWebView.loadDataWithBaseURL(null, url, "text/html",
                "UTF-8", null);

but image can't display.I use HttpURLConnection to read binary stream to load this url, it works.I don't know why can't I load image by using webview.

You got the response in logcat below:

Mixed Content: The page at 'https://' was loaded over HTTPS, 
                 but requested an insecure image.

Webview cannot load the images with http request after 
                 android KITKAT, so we have to set the websetting.

I paste the code below, hope you will solve the problem.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            webview.getSettings().setMixedContentMode(
                        WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
 }
