Question

我有一个从我的数据库中填充的列表视图。现在我想获取这个listview的内容并在html表中显示它。

如何获取listview并将其内容写入html文件？

我在这里做了一些非常相似的事情。

 private File saveResults() {
    /*
     * Write the results to a file.
     */
    List<RiderResult> Results = DataModel.get().getResults();

    try {
        if (!Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
            Toast.makeText(SummaryFragment.this.getContext(), "Unable to access external storage.",
                    Toast.LENGTH_SHORT).show();
            return null;
        }

        /*
         * Create a file folder in external storage.
         */
        File csvDir = new File(
                Environment.getExternalStorageDirectory(),
                "Android/data/ca.mydomain.myapp/results");
        if (!csvDir.exists())
            csvDir.mkdirs();

        /*
         * Create a file in the folder, with today's date and time as the name.
         */
        Date dateNow = new Date ();
        SimpleDateFormat dateformatYYYYMMDD = new SimpleDateFormat("yyyyMMddHHmm");
        StringBuilder nowMMDDYYYY = new StringBuilder( dateformatYYYYMMDD.format( dateNow ) );

        File csvFile = new File(csvDir, "result_" + nowMMDDYYYY + ".csv");

        BufferedWriter bw = new BufferedWriter(new FileWriter(csvFile, false));

        /*
         * Write a header row.
         */
        bw.write("Finish Seq, Start Num,Clock Time, Actual Time\n");

        /*
         * and a row for each result, comma separated
         */
        for (int i = 0; i < Results.size(); i++) {
            String row = new String();
            row = "" + (i + 1) + "," + Results.get(i).getStartNo()
                    + "," + Results.get(i).getClockTimeString() + ","
                    + Results.get(i).getActualTimeString() +"\n";
            bw.write(row);
        }

        bw.close();



        /*
         *  Return the File to the user - for use in a message or email attachment.
         */
        return csvFile;

    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

我正在写一个文件，我后来将其附加到电子邮件或通过BlueTooth发送，或者只是将其存档。我的文件是CSV（竞赛结果），并生成文件名。但你可以适应你的使用。
