Android-Java解析JSON

Question

I'm trying to parse a JSON response and pass the data to list view adapter.

This have worked:

    private void parseJsonFeed(JSONObject response) {
      try {

       JSONArray feedArray = response.getJSONArray("feed");

       for (int i = 0; i < feedArray.length(); i++) {
         JSONObject feedObj = (JSONObject) feedArray.get(i);

               ..........

But this haven't:

    private void parseJsonFeed(JSONObject response) {
      try {

       JSONArray feedArray = response.getJSONArray("feed");

       for (int i = feedArray.length(); i > 1; i--) {
         JSONObject feedObj = (JSONObject) feedArray.get(i);

               ..........

I need to parse the items from last to first, what I'm missing ? It's supposed to be an easy for statement but I've been trying for hours.

Use this instead:

for (int i = feedArray.length() - 1; i >= 0; i--) {

Remember that lists start from 0 and end at (length-1).
