Posting Data on server Using Volley Android

This Tutorial let us know how to post data using volley. Here i will be calling a POST service which will accept parameters and returns a json result .

This is method we will be using to add parameters which we want to send to server.

 
@Override
protected Map getParams() throws AuthFailureError 
{
 // TODO Auto-generated method stub 
return super.getParams(); 
} 


Include Volley library in libs folder of your project,you can download the volley library online.


Project Structure goes like this

1. MainActivity.java

public class MainActivity extends Activity implements OnClickListener
{
private String url = "Your URL";

 private Button hitService;

private ProgressDialog mDialog;

 private TextView mName,mEmail;

@Override  protected void onCreate(Bundle savedInstanceState)
{
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 intiViews();
 }

private void intiViews()
{
hitService=(Button)findViewById(R.id.hitservice);
 hitService.setOnClickListener(this);
 mName=(TextView)findViewById(R.id.name);
 mEmail=(TextView)findViewById(R.id.email);
}
 @Override public void onClick(View v)
{
switch (v.getId())
{
 case R.id.hitservice:
 mDialog=new ProgressDialog(this);
 mDialog.setMessage("Loading");
mDialog.show();
 RequestQueue queue = Volley.newRequestQueue(this);
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST, url, null,  new Response.Listener<JSONObject>()
{                  
@Override                  
public void onResponse(JSONObject response)
{                
  Log.e("Response => ",response.toString());
 }              
}, new Response.ErrorListener()
{                  
@Override                  
public void onErrorResponse(VolleyError error)
{
                  
}              
})
  { //Code to send parameters to server
 @Override
 protected Map getParams() throws AuthFailureError 
{ 
  Map<String,String> params = new HashMap<String, String>();
 params.put("name","YOUR NAME VALUE"); 
 params.put("description", "YOUR description");
 params.put("price", "YOUR price"); 
 return params;
 } 
};
