What Would Be The Simplest Way Of Posting Data Using Volley?

I am trying to use Volley to send 3 strings to a php script that sends it to a localhost server. I have this so far; RegisterRequest; public class RegisterRequest extends StringRe

Solution 1:

Never mess with code or else it will be confusing for you to handle things properly.

So just make another class and use it in your activity.

Have a look at this class i have written, you can use it anywhere and for any type of data request.

publicclassSendData {

privateContext context;
privateString url;
privateHashMap<String, String> data;

privateOnDataSent onDataSent;

publicvoidsetOnDataSent(OnDataSent onDataSent) {
    this.onDataSent = onDataSent;
}

publicSendData(Context context, String url, HashMap<String, String> data) {
    this.context = context;
    this.url = url;
    this.data = data;
}

publicvoidsend(){
    StringRequest stringRequest = newStringRequest(Request.Method.POST, url, newResponse.Listener<String>() {
        @OverridepublicvoidonResponse(String response) {
            if(onDataSent != null){
                onDataSent.onSuccess(response);
            }
        }
    }, newResponse.ErrorListener() {
        @OverridepublicvoidonErrorResponse(VolleyError error) {
            if(onDataSent != null){
                onDataSent.onFailed(error.toString());
            }
        }
    }){
        @OverrideprotectedMap<String, String> getParams() throws AuthFailureError {
            Map<String, String> map = newHashMap<>();
            map.putAll(data);
            return map;
        }

    };
    stringRequest.setRetryPolicy(newDefaultRetryPolicy(0, 0, 0));
    RequestQueue requestQueue =  Volley.newRequestQueue(context);
    requestQueue.add(stringRequest);
}

publicinterfaceOnDataSent{
    voidonSuccess(String response);
    voidonFailed(String error);
}

}

and now you can easily use it from any activity. Just give data in the constructor and use the interface to track the events this way

HashMap<String, String> data = newHashMap<>();
    data.put("username", "");//define the value
    data.put("password", "");//define the value
    data.put("is_admin", "");//define the valueSendData sendData = newSendData(this, "", data); //defie the context and url properly
    sendData.setOnDataSent(newSendData.OnDataSent() {
        @OverridepublicvoidonSuccess(String response) {
            //parse the response 
        }

        @OverridepublicvoidonFailed(String error) {
            //something went wrong check the error
        }
    });
    sendData.send();

hope it helps

happy coding

if some problem occur lemme Know :)
