Android JSON 解析使用 Web 服務查看古吉拉特語字符

Question

在 Android JSON 解析中使用 Web 服務查看古吉拉特語字符

我得到了古吉拉特語單詞，就像我包含的圖像中的單詞一樣。 如果古吉拉特語單詞顯示為અપૂર્વ，則它顯示為圖像中的第一個圓圈。

請幫我找到解決這個問題的辦法

像這樣獲取古吉拉特語單詞的圖像如下所示：

這是我的代碼：

public class GetProductData extends AsyncTask<String, String, JSONObject> {

    //private ProgressDialog p_dialog;
    JSONArray jArray;

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        /*p_dialog = new ProgressDialog(con);
        p_dialog.setMessage("Please Wait ...");
        p_dialog.setIndeterminate(false);
        p_dialog.setCancelable(false);
        p_dialog.show();*/
    }

    @Override
    protected JSONObject doInBackground(String... params) {
        jArray = JSONParser.GetProductData();

        Log.d("TAG", "JSON ARRAY FOR DEVICE ID : " + jArray);
        String msg = "Nothing Happened...";
        try {
            if (jArray != null) {
                Key = jArray.getJSONObject(0).getString("Key").toString();

                if (Key.equals("1")) {
                    db.deleteAllProductDetails();


                    for (int i = 1; i < jArray.length(); i++) {

                        Log.d("ADADADADTAG","CategoryName ::: "+jArray.getJSONObject(i).getString("CategoryName"));
                        Log.d("ADADADADTAG","SubCategoryName ::: "+jArray.getJSONObject(i).getString("SubCategoryName").trim());
                        Log.d("ADADADADTAG","ProductName ::: "+jArray.getJSONObject(i).getString("ProductName"));

                        db.insertProductDetails(
                                jArray.getJSONObject(i).getString("ProductId").trim(),
                                jArray.getJSONObject(i).getString("CategoryId").trim(),
                                jArray.getJSONObject(i).getString("CategoryName").trim(),
                                jArray.getJSONObject(i).getString("CategoryImageUrl").trim(),
                                jArray.getJSONObject(i).getString("SubCategoryId").trim(),
                                jArray.getJSONObject(i).getString("SubCategoryName").trim(),
                                jArray.getJSONObject(i).getString("SubCategoryImageUrl").trim(),
                                jArray.getJSONObject(i).getString("ProductName").trim(),
                                jArray.getJSONObject(i).getString("ProductImageUrl").trim(),

                        );

                    }

                }

Answer 1

使用 URLDecoder 解析 Json 數據，

URLDecoder.decode(jArray.getJSONObject(i).getString("CategoryName"), "utf-8");

Answer 2

試試這個

StringRequest stringRequest = new StringRequest(Request.Method.GET,"http://floming.com/shayri/guj_romanse.json", new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        String str = "";
        try {
            str = new String(response.getBytes("ISO-8859-1"), "UTF-8");
        } catch (UnsupportedEncodingException e) {

            e.printStackTrace();
        }

        String decodedStr = Html.fromHtml(str).toString();
