  1. PODuplicate data in ListView when Searching
    text
    copied!<p>I'm trying to do search which include images and textview. So when I search it returns the positive result, but when i go back and search with other value it returns the old return and new result at the same time. I want my listView not to add old data into it. I need to over write the old data with a new value. here my code :</p> <pre><code>public void onClick(View Kv) { Intent moreDetailsIntent = new Intent(MainMenu.this,ListMobileActivity.class); Bundle dataBundle = new Bundle(); dataBundle.putString("Prov","KwaZulu-Natal"); moreDetailsIntent.putExtras(dataBundle); startActivity(moreDetailsIntent); }); B_GP.setOnClickListener(new View .OnClickListener() { @Override public void onClick(View Gv) { Intent moreDetailsIntent = new Intent(MainMenu.this,ListMobileActivity.class); Bundle dataBundle = new Bundle(); dataBundle.putString("Prov","Gauteng"); moreDetailsIntent.putExtras(dataBundle); startActivity(moreDetailsIntent); } }); </code></pre> <p>When i click a first buttonKZN it must display all KZN provinces and when click buttonB_GP it must return all GP province. so what it does it just return the old data when i search for the second time, here my listView classess :</p> <pre><code>Bundle b = getIntent().getExtras(); // Getting the Bundle object that pass from another activity String SelectedProv = b.getString("Prov"); List&lt;NameValuePair&gt; params = new ArrayList&lt;NameValuePair&gt;(); params.add(new BasicNameValuePair("ProvinceName",SelectedProv)); Log.d("ProvinceName",SelectedProv); JSONObject json = jsonParser.makeHttpRequest("http://10.0.2.2/php/searchKZN.php", "POST", params); try{ JSONArray earthquakes = json.getJSONArray("PROV"); for(int i=0;i&lt;earthquakes.length();i++){ JSONObject e = earthquakes.getJSONObject(i); String PCity = e.getString("P_City"); PNames.add(PCity); String Pimage = e.getString("Pname"); PImages.add(Pimage); } } catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } setListAdapter(new MobileArrayAdapter(this, PNames,PImages)); </code></pre> <p>So please help me to diplay the correct values according to selected button.</p>
