How to show listviewitem when i input a text into Edittext. I searched already from the net but i dont have an idea on how to do it.
This is the code
MainActivity.java
public class MainActivity extends ListActivity {
private ProgressDialog pDialog;
private EditText et,search;
private static final String URL = "http://192.168.254.101/productlist.php";
JSONParser jsonParser = new JSONParser();

private static final String TAG_POSTS = "message";
private static final String TAG_BRAND = "Brand";
private static final String TAG_CATEGORY = "Category";
private static final String TAG_DESCRIPTION = "Description";
private static final String TAG_CODE = "Code";
private static final String TAG_QUANTITY = "Quantity";
private static final String TAG_UNIT = "Unit";
private static final String TAG_UNITPRICE = "Unitprice";
private JSONArray mComments = null;
//manages all of our comments in a list.
private ArrayList<HashMap<String, String>> mCommentList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
search = (EditText)findViewById(R.id.EditText01);
setContentView(R.layout.activity_main);
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
//loading the comments via AsyncTask
new LoadComments().execute();
}
public void updateJSONdata() {
int success;
String searchdesc = search.getText().toString();
mCommentList = new ArrayList<HashMap<String, String>>();
try {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", searchdesc));
JSONObject json = jsonParser.makeHttpRequest(
URL, "POST", params);
success = json.getInt(Success);
mComments = json.getJSONArray(TAG_POSTS);
for (int i = 0; i < mComments.length(); i++) {
JSONObject c = mComments.getJSONObject(i);
//gets the content of each tag
String brand = c.getString(TAG_BRAND);
String category = c.getString(TAG_CATEGORY);
String description = c.getString(TAG_DESCRIPTION);
String code = c.getString(TAG_CODE);
String quantity = c.getString(TAG_QUANTITY);
String unit = c.getString(TAG_UNIT);
String unitprice = c.getString(TAG_UNITPRICE);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_BRAND, brand);
map.put(TAG_CATEGORY, category);
map.put(TAG_DESCRIPTION, description);
map.put(TAG_CODE, code);
map.put(TAG_QUANTITY, quantity);
map.put(TAG_UNIT, unit);
map.put(TAG_UNITPRICE, unitprice);
mCommentList.add(map);
}
} catch (JSONException e) {

$json["success"]=1;
$json["message"]=$records;
echo json_encode($json);
?>

ok i edit my answer with your case
please put this line in onCreate method:
setContentView(R.layout.activity_main);
on top of this line
search = (EditText)findViewById(R.id.EditText01);
after that call this method
search = (EditText) findViewById(R.id.EditText01);
txt.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
updateJSONdata(s.toString());
}
});
after that change updateJSONdata method first line to this
public void updateJSONdata(String searchdesc){
and comment this line
String searchdesc = search.getText().toString();
maybe this help

Parsing Problem first I got.Change
JSONArray array = jsonObject.getJSONArray("bedehkariHa");
To:
JSONArray array = jsonObject.getJSONArray("bedehkari_ha");
Then check

According to the result from JSON, the key bedehkariHa does not exist and that may cause Parsing Error, a JSONException. So instead of this:
JSONArray array = jsonObject.getJSONArray("bedehkariHa");
use this to get the JSONArray associated with bedehkari_ha:
JSONArray array = jsonObject.getJSONArray("bedehkari_ha");

I'd firstly look at your general approach.
You seem to be instantiating a Volley request...I bet this isn't the only one in your app?
Make a "NetworkService" singleton that holds application Context and call that as a service layer...rather than calling a new Volley instance for each class you need it!
Here is one I wrote for my apps...I have omitted a lot of the methods and left you with a GetRequest method. You could add the URLEncoding of parameters in the service.
You can call this by simply in an activity/fragment:
HashMap<String,String> urlParams = new HashMap<>();
urlParams.put("param1","value1");
VolleyRequestService.getInstance(this).getJSONObject(urlParams, true, new GetJSONObjectRequestable() {
#Override
public void onSuccessfulAPIResponse(JSONObject response) {
}
#Override
public void onFailedAPIResponse(VolleyRequestService.ErrorType errorType, String description) {
}
},"https://myendpoint.com/endpoint.php");
And the service:
package devdroidjonno.com.tests.Networking;
import android.content.Context;
import android.util.Log;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.toolbox.JsonObjectRequest;
import com.android.volley.toolbox.Volley;
import java.util.HashMap;
import java.util.Map;
public class VolleyRequestService {
private static final String DEBUG = "VolleyRequestService";
private static final String authCode = "87fe987vwefb987eb9w87wv";
private static VolleyRequestService ourInstance = null;
private static RequestQueue requestQueue;
private VolleyRequestService(Context applicationContext) {
this.requestQueue = Volley.newRequestQueue(applicationContext);
Log.d(DEBUG, "Init Volley Service " + this.hashCode());
}
public static VolleyRequestService getInstance(Context context) {
