When I click on a button within my listview, I call a function where I send a value clearly depending on which button is clicked. When I get a positive response function of the item field changes value, in the first instance is to validado = 0 and if you click on the button changes to validado = 1. If validated this to 1, the button should have a background image as warning that this item is already validated. All this works well for me at first, but if I click on any button, regardless of how many items are on my list, always changes the item to which it is clicked and also the first item on my list. Pretty funny when my data base both locally and in my server, the validated value of the first item remains 0

I show logs to show that the value is still 0
08-07 13:39:21.890: I/System.out(14317): item 936 validado = 0
08-07 13:39:21.890: I/System.out(14317): item 937 validado = 0
08-07 13:39:21.890: I/System.out(14317): item 938 validado = 0
This log out when you first enter the view of the listview, then I will validate an inscription, whatever, and this is what I get
08-07 13:44:08.300: I/System.out(14317): item 936 validado = 0
08-07 13:44:08.300: I/System.out(14317): item 937 validado = 1
08-07 13:44:08.305: I/System.out(14317): item 938 validado = 0
That's all right, except the first item plus the charge to the button that validates an image which I just want to be charged to the element that is in rowItem.getValidado()==1
EDIT
I answered my question.
So you click on 1 item on the ListView it changes it look (which is intended), because your value changes to 1. But no matter what, the first Visible item in the ListView also changes (unintended)?
I am no expert but I gather you have an issue with your ViewHolder. Try removing the ViewHolder logic and see if you still get the issue (for testing). ListView is tricky with the recycling of Views and repopulating them with new data. Might even have an issue with your getItem(). But I suspect it's the ViewHolder logic.
Also do you need to declare that Inflater every time getView() is called? prob ought to move that up to Constructor and just instantiate it in the getView().
The error was where the code to and not how.

I'll try my best explaining whats happening, so my code has a forloop which fills a listview, this listview is showing all the correct data from a json file, excpet for the images, the images are always from the last position in the listview and then copied to the one above, for example here
This is one single activity which i just and to snippet to make it fit. I'm guessing its something to do with the strings which i create to make the images, they are somehow being used twice, and then used again to fill the listview, even though all of the other strings are being reset and filled when its gets the new information from the JSON. Heres my code if anyone would could tell me why this is only happening to the images and not the strings which create the names of items

When i put a log.v at the bottom of the code, it always replies this
05-21 14:41:40.646 4536-4536/com.example.kripzy.url V/Where is my error: enchantment:bloodrazor
05-21 14:41:40.659 4536-4536/com.example.kripzy.url V/Where is my error: enchantment:bloodrazor
So what i was doing wrong was i was just using a string which just contained the information from the last entry on the listview, hence why it was only showing the images from it, so to fix this i had to change it to the following;
ItemNameInLowerCase = holder.champitem1.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName2InLowerCase = holder.champitem2.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName3InLowerCase = holder.champitem3.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName4InLowerCase = holder.champitem4.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName5InLowerCase = holder.champitem5.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName6InLowerCase = holder.champitem6.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemNameInLowerCaseHW = holder.champitem1HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName2InLowerCaseHW = holder.champitem2HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName3InLowerCaseHW = holder.champitem3HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName4InLowerCaseHW = holder.champitem4HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");

i Given whole code i want custom listview using listfragments
In the above code in this line, I'm getting an error at adapter = new Appetizerlist(this, json); Please tell me how to solve the problem. Help me.
as onCreate called before onCreateView so list will null there in onCreate ...........
http://developer.android.com/guide/topics/fundamentals/fragments.html
in oncreate
list.setAdapter(adapter);
in onCreateView you initlized that
list = (ListView) view.findViewById(R.id.list);
......
so move this line list.setAdapter(adapter); in onCreateView
You have error in following line.
adapter = new Appetizerlist(this, json);
Change it to
adapter = new Appetizerlist(getActivity().getApplicationContext(), json);
I'm begginer develop android.
I'm confuse. Because I didn't know to convert JSON to be view at Edit View (for example).
many totorial just view at Log.
this, my JSON file
EditText txt1 = (EditText) findViewById(R.id.Text1);
RestClient client = new RestClient("http://192.168.2.79/restserver/index.php/api/example/users");
//client.AddParam("id", "1"); //parameter
client.AddParam("format", "json"); //parameter format
client.AddHeader("GData-Version", "2"); //header
try {
client.Execute(RequestMethod.GET);
} catch (Exception e) {
e.printStackTrace();
}
String response = client.getResponse();
Log.i("respon",response);
//Toast.makeText(this, "json : "+ response, 1).show();
//create json creation
try {
JSONObject json = new JSONObject(response);
Log.i("respon","<jsonobject>\n"+json.toString()+"\n</json>");
//Log.i("respon","<jsonobject>\n"+json.t
JSONArray nameArray = json.names();
JSONArray valArray = json.toJSONArray(nameArray);
//try 1
JSONObject object = (JSONObject) new JSONTokener(response).nextValue();
String[] id = new String[valArray.length()];
String[] name = new String[valArray.length()];
String Id,Name;
for(int i=0;i<valArray.length();i++) {
Log.i("respon","<jsonname"+i+">\n"+nameArray.getString(i)+"\n</jsonname"+i+">\n"
+"<jsonvalue"+i+"\n"+valArray.getString(i)+"\n</jsonvalue"+i+">");
//coba
JSONObject obj = valArray.getJSONObject(i);
id[i] = obj.getString("id");
name[i] = obj.getString("name");
//wanna show at EditView, ect (but I can't)
Toast.makeText(this, "id : " + " ,name : ", 1).show();
txt1.setText("id : " + id + " ,name : "+name);
}
how can to solve json to view not only at log. but also at object (widget android).
thanx alot guys....
I think your not able to get data from JSON go through with the following code.
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("LINK");
HttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
StatusLine statusLine = response.getStatusLine();
int statuscode = statusLine.getStatusCode();
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(is, "UTF8"), 16);
stringBuilder = new StringBuilder();
stringBuilder.append(bufferedReader.readLine() + "\n");
String line = "0";
while ((line = bufferedReader.readLine()) != null) {
stringBuilder.append(line + "\n");
is.close();
Strign result = stringBuilder.toString();
JSONArray jArrayTemp = new JSONArray(result);
JSONObject json_data = null;
userID[i] = json_data.getString("UserID");
userName[i] = json_data.getString("UserName");
userLoginID[i] = json_data.getString("UserLoginID");
userPassword[i] = json_data.getString("UserPassword");
Try the above code.
If can take the help of below link also::

PLESE HELP!
If your json contains image url you can use
String imageBaseDirectory = "http://www.dha.com.tr/newpics/news/";
String imageName = "230620111119295717933.jpg";//get image name from json parsing;
imageview.setImageURI(Uri.parse(imageBaseDirectory+imageName));
But I can see that the url that you are referring donot contain image url only it contains name of image
do you have image url in json ?? if so , then create another http connection for this url , get inputstream , then create bitmap from this stream .
else clarify here what kind of info you have for image in your json ??
Your JSON contains the filename. Assuming you know the path of the images, form the url and do as Shailendra suggested, example:
URL url = new URL(imgBaseUrl + ss.getString("foto"));
URLConnection connection = url.openConnection();
FlushedInputStream fis = new FlushedInputStream(connection.getInputStream());
ByteArrayBuffer baf = new ByteArrayBuffer(100);
int current = 0;
while((current = fis.read()) != -1){
baf.append((byte)current);
}
fis.close();
holder.resim.setImageBitmap(BitmapFactory.decodeByteArray(baf, 0, baf.length()));
Be sure to use FlushedInputStream as seen at http://code.google.com/p/android/issues/detail?id=6066
static class FlushedInputStream extends FilterInputStream {
public FlushedInputStream(InputStream inputStream) {
super(inputStream);
}
#Override
public long skip(long n) throws IOException {
long totalBytesSkipped = 0L;
while (totalBytesSkipped < n) {
long bytesSkipped = in.skip(n - totalBytesSkipped);
if (bytesSkipped == 0L) {
int bite = read();
if (bite < 0) {
break; // we reached EOF
} else {
bytesSkipped = 1; // we read one byte
}
}
totalBytesSkipped += bytesSkipped;
}
return totalBytesSkipped;
}
}

How to load an imageView by URL in Android
1) create the url and pass it to the method in the link I provided
String myPhoto = "foto2";
String url = "http://mysite.com/images/" + myPhoto + ".png";
How to load an image from a json? Use of picasso, it is easy:
String imageUrl = imgBaseUrl + ss.getString("foto"); // this is the image url
Picasso.with(this.getActivity()).load(imageUrl).into(holder.resim); // holder.resim is the imageview
