Get A Array From Mysql To Android

I have made an php code to get the array of data from MYSQL but now i am struggling to get it back to my android and just to toast it. Here is my php code: if($_SERVER

Solution 1:

Modify your showEmployee like this:

privatevoidshowEmployee() {
    JSONObject jsonObject = null;
    ArrayList<HashMap<String, String>> list = newArrayList<HashMap<String, String>>();
    try {
        jsonObject = newJSONObject(JSON_STRING);
        JSONObject result = jsonObject.getJSONObject(TAG_JSON_ARRAY);
        JSONArray jsonTags = result.getJSONArray(KEY_USER_TAGS);

        for (int i = 0; i < jsonTags.length(); i++) {
            tags = tags + jsonTags.getString(i);

            HashMap<String, String> employees = newHashMap<>();
            employees.put(KEY_USER_TAGS, jsonTags.getString(i));

        }

    } catch (JSONException e) {
        e.printStackTrace();
    }
}

and set your tags string to an empty string (else the first object will be null)

publicstaticStringtags="";

The code still has some logic flaws, your employees HashMap will only contain the last entry, because you are always creating a new HashMap.

Solution 2:

Hey AsyncTask does not work synchronously, if you toast like this it will work.

privatevoidshowEmployee() {
JSONObject jsonObject = null;
ArrayList<HashMap<String, String>> list = newArrayList<HashMap<String, String>>();
try {
    jsonObject = newJSONObject(JSON_STRING);
    JSONArray result = jsonObject.getJSONArray(TAG_JSON_ARRAY);

    for (int i = 0; i < result.length(); i++) {
        JSONObject jo = result.getJSONObject(i);
        tags = jo.getString(KEY_USER_TAGS);

        HashMap<String, String> employees = newHashMap<>();
        employees.put(KEY_USER_TAGS, tags);

    }

} catch (JSONException e) {
    e.printStackTrace();
}
Toast.makeText(getApplicationContext(),JSON_STRING.toString(),Toast.LENGTH_LONG).show();}

Basically your tags string will get populated only after shoEmployee() finishes up and that will get called after onPostExecute of GetJSON.
