Pab*_*nez 4 android image sd-card webview
我已经在sdcard的根目录中下载了map750.png文件,但是当我尝试在带有某些文本的webview中显示它时,只显示了文本.你能帮我找一下代码中的错误吗？谢谢.
setContentView(R.layout.webview);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setBuiltInZoomControls(true);
String html = "<html><head></head><body><p>hello</p><img src=\"file://mnt/sdcard/map750.png\" alt=\"alternativo\" /></body></html>";
mWebView.loadData(html, "text/html","utf-8");
我编辑帖子添加oneilse14建议的解决方案,谢谢!!

mWebView.loadDataWithBaseURL("", html, "text/html", "utf-8", "");
试试这个,
final String fileName = "file:///mnt/sdcard/1.jpg";
final String mimeType = "text/html";
final String encoding = "utf-8";
final String html = "<img src=\""+fileName+"\">";
webView.loadDataWithBaseURL("", html, mimeType, encoding, "");
