How Do I Make My Connection An Asynctask Connection

UPDATE: I found that the easiest way is to use AQuery. I need to get my HttpPost for getting JSON data on another thread and I dont know how to get it all working together. Ive lo

Solution 1:

I think you can try something like this:

publicclassMyActivityextendsActivity {

// paring dataint q_id;
String q_label;
String q_title;
String q_description;
String q_gotoURL;
Context context;

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stubsuper.onCreate(savedInstanceState);
    mList = (ListView) findViewById(R.id.sidebar_list);
    context = getApplicationContext();
    newHttpTask().execute("http://192.168.1.34/xxxx/xxxxx_list.php");

}
privateclassHttpTaskextendsAsyncTask<String, Void, String> {


    protected String doInBackground(String... urls) {
        try {
            HttpClienthttpClient=newDefaultHttpClient();
            HttpPosthttpPost=newHttpPost(urls[0]);

            List<NameValuePair> nameValue = newArrayList<NameValuePair>();
            httpPost.setEntity(newUrlEncodedFormEntity(nameValue));

            HttpResponsehttpResponse= httpClient.execute(httpPost);

            HttpEntityhttpEntity= httpResponse.getEntity();

            is = httpEntity.getContent();

            // Get resultBufferedReaderBufR=newBufferedReader(newInputStreamReader(is, "iso-8859-1"), 8);
            sb = newStringBuilder();
            sb.append(BufR.readLine() + "\n");

            Stringline="0";
            while ((line = BufR.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result = sb.toString();

        } catch (Exception e) {
            Toast.makeText(context, "HTTP Connection Error : " + e.toString(), Toast.LENGTH_LONG).show();
            returnnull;
        }
    }

    protectedvoidonPostExecute(String result) {
        try {
            if(result == null)
                thrownewException("result is null");
            jArray = newJSONArray(result);
            JSONObjectjson_data=null;
            for (inti=0; i < jArray.length(); i++) {
                json_data = jArray.getJSONObject(i);
                q_id = json_data.getInt("_ID");
                q_label = json_data.getString("label");
                q_title = json_data.getString("title");
                q_description = json_data.getString("description");
                q_gotoURL = json_data.getString("gotoURL");
                // mList.add();
            }
            //send message to handler to draw list
            drawListHandler.sendEmptyMessage(0);
        } catch (Exception e1) {
            Toast.makeText(context, e1.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
}

HandlerdrawListHandler=newHandler(){
    /* (non-Javadoc)
     * @see android.os.Handler#handleMessage(android.os.Message)
     */@OverridepublicvoidhandleMessage(Message msg) {
        setupList();
    }
};
}

Solution 2:

Other than setupList() (assuming that updates some ListView) and the Toast, the rest of that should be in doInBackground(). You want as little code as possible to be on the main application thread.
