Question

我正在处理需要在Web视图中显示一些信息的项目，但是需要通过组合存储在内部存储上的两个或多个文件(html/text)来动态生成文件，我能够组合文件但不能能够在webview中呈现它。请指导......

这是代码

String html= CheckLocalHtml(context,"FileName.html")
webViewBasic.loadDataWithBaseURL("file:///",html,"text/html", "utf-8", null);

public String CheckLocalHtml(Context context, String fName) {
    try {
        String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS).toString();
        File mFile, mDir;
        mDir = new File(root);
        if (mDir.exists()) {
            mFile = new File(mDir, fName);
            if (mFile.exists()) {
                StringBuilder contentBuilder = new StringBuilder();
                BufferedReader in = new BufferedReader(new FileReader(mFile));
                String s="";
                while ((s = in.readLine()) != null) {
                    contentBuilder.append(s);
                }
                in.close();
                return contentBuilder.toString();
            } else {
                Toast.makeText(context, "Page not found", Toast.LENGTH_SHORT).show();
            }
        } else {
            Toast.makeText(context, "Directory not found", Toast.LENGTH_SHORT).show();
        }
    } catch (Exception e) {
        Log.e("ReadHTML","Error="+e.toString());
    }
}

我已经把它弄清楚....已保存的文件存储并使用了webViewBasic.loadUrl（＆＃34; file：///＆＃34; + file.getAbsolutePath（））;

合并text / html文件并在webview中渲染
