How to Make a Custom ArrayAdapter for ListView - android-listview

I have to make a custom ArrayAdapter from the JSON response I'm getting. Here is my code from where I'm getting response and putting it in simple ArrayAdapter with android.R.layout.simple_list_item_1
ListView lv = (ListView) findViewById(R.id.list);
try {
HttpClient hClient = new DefaultHttpClient();
HttpGet hGet = new HttpGet(
"API HERE");
ResponseHandler<String> rHandler = new BasicResponseHandler();
data = hClient.execute(hGet, rHandler);
JSONObject rootObj = new JSONObject(data);
JSONObject searchObj = rootObj.getJSONObject("searchdata");
JSONArray titlesObj = searchObj.getJSONArray("titles");
JSONArray descsObj = searchObj.getJSONArray("desc");
JSONArray linksObj = searchObj.getJSONArray("links");
String[] a = new String[titlesObj.length()];
String[] b = new String[descsObj.length()];
String[] c = new String[linksObj.length()];
for (int i = 0; i < titlesObj.length(); i++) {
String title = titlesObj.getString(i);
a[i] = title;
}
for (int i = 0; i < descsObj.length(); i++) {
String desc = descsObj.getString(i);
b[i] = desc;
}
for (int i = 0; i < linksObj.length(); i++) {
String link = linksObj.getString(i);
c[i] = link;
}
ArrayList<String> al = new ArrayList<String>();
for (int i = 0; i < linksObj.length(); i++)
{
al.add(" " + a[i] + " " + b[i] + "" + c[i] + "");
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
MainActivity.this, android.R.layout.simple_list_item_1, al);
lv.setAdapter(adapter);
} catch (Exception e) {
}
Here, is the screenshot of my view:
I want to show the view which has three TextView one for the title, another one for URL and the last one for description.
Any help will be appreciated.

Make a Custom Adapter. Set that adapter to your listview. Your Adapter class should extend ArrayAdapter. In getView() inflate your custom xml with 3 textviews . Use a viewholder for performance.
Hers's an example http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/. Hers's a bit more to listview http://www.youtube.com/watch?v=wDBM6wVEO70.
how to set json parsed data in a listview and then adding search functionality in it. Have a look at the answer. I have used hashmap and displayed data in listview accordingly with search on listview items. Modify the same according to your needs.

Anupam, you can place the small data like
al.add(" " + apple + " " + ball + "" +cat + "");
in single row in single line. If u want to keep that much data(above mentioned in image in one single row) in single row in single line is not possible.

How do I save Xml Changes Back to the Original Document

I need to update the Styles (styles.xml) part of an MS Word document due to a problem with a vendor's product.
So far I've been able to extract and update the xml I need. The only problem, is that I don't know how to save my changes back to the document.
The code below is working just fine. I usually output the xml to the console to make sure it's going in just fine. At the end, I know I need to perform some save operation, but the XDocument.Save( /stream/) hasn't worked.
Here's where I am so far
static void FixNormal()
{
using (WordprocessingDocument doc = WordprocessingDocument.Open(_path, true))
{
// Get the Styles part for this document.
StyleDefinitionsPart stylesPart = doc.MainDocumentPart.StyleDefinitionsPart;
// If the Styles part does not exist, add it and then add the style.
if (stylesPart == null)
{
Console.WriteLine("No Style Part");
}
else
{
XDocument stylesDoc;
using (var reader = XmlNodeReader.Create(stylesPart.GetStream(FileMode.Open, FileAccess.Read)))
{
XNamespace w = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
Console.WriteLine(stylesPart.Styles.OuterXml);
// Create the XDocument.
stylesDoc = XDocument.Load(reader);
var xStyle = stylesDoc.Descendants(w + "styles").Descendants(w + "style").Where(x => x.Attribute(w + "styleId").Value.Equals("Normal"));
XElement style = xStyle.Single();
var q = style.Descendants(w + "qFormat").FirstOrDefault();
if (q is null)
{
XElement qFormat = new XElement(w + "qFormat");
style.Add(qFormat);
}
var r = style.Descendants(w + "rsid").FirstOrDefault();
if (r is null)
{
XElement rsid = new XElement(w + "rsid");
XAttribute val = new XAttribute(w + "val", "003C4F1E");
rsid.Add(val);
style.Add(rsid);
}
}
//doc.Save(); --- Did not work
}
}
}
I found the answer in the SAVE THE PARTS section of this page Replace the styles parts in a word processing document (Open XML SDK)
See the end of this code for the solution. You'll also see what I've tried.
static void FixNormal()
{
using (WordprocessingDocument doc = WordprocessingDocument.Open(_path, true))
{
// Get the Styles part for this document.
StyleDefinitionsPart stylesPart = doc.MainDocumentPart.StyleDefinitionsPart;
// If the Styles part does not exist, add it and then add the style.
if (stylesPart == null)
{
Console.WriteLine("No Style Part");
}
else
{
XDocument stylesDoc;
using (var reader = XmlNodeReader.Create(stylesPart.GetStream(FileMode.Open, FileAccess.Read)))
{
XNamespace w = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
// Create the XDocument.
stylesDoc = XDocument.Load(reader);
var xStyle = stylesDoc.Descendants(w + "styles").Descendants(w + "style").Where(x => x.Attribute(w + "styleId").Value.Equals("Normal"));
XElement style = xStyle.Single();
var q = style.Descendants(w + "qFormat").FirstOrDefault();
if (q is null)
{
XElement qFormat = new XElement(w + "qFormat");
style.Add(qFormat);
}
var r = style.Descendants(w + "rsid").FirstOrDefault();
if (r is null)
{
XElement rsid = new XElement(w + "rsid");
XAttribute val = new XAttribute(w + "val", "003C4F1E");
rsid.Add(val);
style.Add(rsid);
}
}
//doc.Save(); --- Did not work
//stylesDoc.Save(#"C:\WinTest\HooRah.xml"); -- I only use this to verify that I've updated everything correctly
//using (XmlWriter xw = XmlWriter.Create(stylesPart.GetStream(FileMode.Create, FileAccess.Write)))
//{
// stylesDoc.Save(xw); -- DID NOT WORK EITHER
// doc.Save();
//}
// THIS WORKED
stylesDoc.Save(new StreamWriter(stylesPart.GetStream(FileMode.Create, FileAccess.Write)));
}
}

How to fetch table data in Entity Framework and assign it to any Button or Texbox without using where condition

How I can do this in Entity Framework?
sSQL = "SELECT CategoryName FROM CategorySetup";
if (Conn.State == ConnectionState.Closed) { Conn.Open(); }
cmd = new SqlCommand(sSQL, Conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
btn_Chicken.Text = dt.Rows[0]["CategoryName"].ToString();
btn_Beef.Text = dt.Rows[1]["CategoryName"].ToString();
btn_Rice.Text = dt.Rows[2]["CategoryName"].ToString();
btn_Drink.Text = dt.Rows[3]["CategoryName"].ToString();
How I can do same thing in Entity Framework 5.0? If anybody knows, please tell me I'm searching it on google but cant find it, I'm new to ASP.NET MVC and Entity Framework
Once you have your EF context set up, fetching the data per se is simple:
List<CategorySetup> listOfCat = yourDbContext.CategorySetup;
But the main question is: how do you know which of those objects you got back from the database table corresponds to the button in your GUI?? Do you have a column in your database table to order your data by? So that you always now row #0 is for btn_Chicken, row #1 is for btn_Beef ? Or is there a column on the CategorySetup table to allows you to find out which CategorySetup object to use for which button?
POS_EF_Project.DataBase_Create.POS_Context db = new POS_EF_Project.DataBase_Create.POS_Context();
Button[] buttonArray = new Button[9];
public frmTesting()
{
InitializeComponent();
}
// Display Function
public void Display(int i)
{
string index = buttonArray[i].Tag.ToString();
var itm = db.ItemSetups.Where(c => c.CatagoryCode == index).OrderBy(c => c.ItemName);
int iCounter = 0;
foreach (ItemSetup t in itm)
{
fp_Items.Sheets[0].Rows.Count = iCounter + 1;
fp_Items.Sheets[0].Cells[iCounter, 0].Text = t.ItemCode;
fp_Items.Sheets[0].Cells[iCounter, 1].Text = t.ItemName;
fp_Items.Sheets[0].Cells[iCounter, 2].Text = t.Price.ToString();
iCounter++;
}
}
private void btn_Start_Click(object sender, EventArgs e)
{
var cat = db.Categorys.ToList();
int horizotal = 6;
int vertical = 96;
for (int i = 0; i < buttonArray.Length; i++)
{
int index = i;
buttonArray[i] = new Button();
buttonArray[i].Size = new Size(168, 40);
buttonArray[i].Location = new Point(horizotal, vertical);
buttonArray[i].TextAlign = ContentAlignment.MiddleLeft;
buttonArray[i].Text = cat[i].CatagoryName;
buttonArray[i].Tag = cat[i].CategoryCode;
buttonArray[i].ImageAlign = ContentAlignment.MiddleRight;
buttonArray[i].Image = (Image)Properties.Resources.ResourceManager.GetObject("Basket");
if ((i + 1) % 9 == 0) horizotal = 6;
else vertical += 42;
buttonArray[i].Click += (sender1, ex) => this.Display(index);
this.Controls.Add(buttonArray[i]);
}
}
}
}

android - trying to create listview

i'm trying to write data from sqlite to a listview. the compiler doesn't show error, but when I run the app on my phone, it crashes. please help me
Cursor resultSet = db.rawQuery("Select * from weight_listview ORDER BY `id` DESC",null);
resultSet.moveToFirst();
String[] list = new String[] {};
String[] weighttolist={};
String[] datetolist={};
ArrayList<String> List=new ArrayList<String>();
ArrayList<String> List2=new ArrayList<String>();
resultSet.moveToFirst();
int x = 0;
while(resultSet.moveToNext()){
String data = resultSet.getString(resultSet.getColumnIndex("weight"));
String data2 = resultSet.getString(resultSet.getColumnIndex("date"));
String id = resultSet.getString(resultSet.getColumnIndex("ID"));
List.add(data + " " + data2);
x++;
}
final ListView listView = (ListView) findViewById(R.id.listView1);
if(List != null){
weighttolist=(String[])List.toArray(new String[0]);
String[] from = { "weight", "date" };
int[] to = { R.id.weight, R.id.date };
SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this,R.layout.row, resultSet, from, to);
listView.setAdapter(cursorAdapter);
// ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
// android.R.layout.simple_list_item_1, android.R.id.text1, weighttolist);
// ListView.setAdapter(adapter);
}
edit:
I successed to fix the problem but now I have another problem. I want that the listview will show 2 columns , not only 1 . I created fill row.xml , as you can see in the first code.
Cursor resultSet = db.rawQuery("Select * from weight_listview ORDER BY `id` DESC",null);
resultSet.moveToFirst();
String[] list = new String[] {};
String[] weighttolist={};
String[] datetolist={};
ArrayList<String> List=new ArrayList<String>();
ArrayList<String> List2=new ArrayList<String>();
resultSet.moveToFirst();
int x = 0;
while(resultSet.moveToNext()){
String data = resultSet.getString(resultSet.getColumnIndex("weight"));
String data2 = resultSet.getString(resultSet.getColumnIndex("date"));
List.add(data + " " + data2);
x++;
}
final ListView listView = (ListView) findViewById(R.id.listView1);
if(List != null){
weighttolist=(String[])List.toArray(new String[0]);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, weighttolist);
listView.setAdapter(adapter);
}
Well without the exact error it is hard to see what is going wrong. Here is my guess you are using a SimpleAdapter who's constructor looks like this
SimpleAdapter(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to)
For your second parameter you are using a Cursor not a list, your from variable are keys so you need to use a hash map I believe
Comment out your code and try this
List<HashMap<String, String>> List = new ArrayList<HashMap<String, String>>();
int x = 0;
while(resultSet.moveToNext()){
HashMap<String, String> map = new HashMap<String, String>();
String weight = resultSet.getString(resultSet.getColumnIndex("weight"));
String date = resultSet.getString(resultSet.getColumnIndex("date"));
String id = resultSet.getString(resultSet.getColumnIndex("ID"));
map.put("weight", weight);
map.put("date", date);
List.add(map);
x++;
}
final ListView listView = (ListView) findViewById(R.id.listView1);
if(List != null){
weighttolist=(String[])List.toArray(new String[0]);
String[] from = { "weight", "date" };
int[] to = { R.id.weight, R.id.date };
SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this,R.layout.row, List, from, to);
listView.setAdapter(cursorAdapter);

Passing database data to another activity

how can I pass an array of strings and integers which contains the database data into another activity...I don't know how to put the database data on the string array
You can use this method to retrieve data from the table
public List<String[]> getData(String query) throws SQLException{
Cursor c = mdb.rawQuery(query, null);
c.moveToFirst();
List<String[]> data = new ArrayList<String[]>();
if (c != null) {
for (int i = 0; i < c.getCount(); i++) { // iterate rows
String[] row = new String[c.getColumnCount()];
for(int j = 0; j < c.getColumnCount(); j++){//iterate columns
row[j] = c.getString(j);
}
data.add(row);
c.moveToNext();
}
}
c.close();
Log.i("getData", data.size() + " rows returned");
return data;
}
Each row of the result will be contained in each String[] of the list.
Say, intentData is a String[] and you want to pass the data to the next activity.For this, you have to add the data to the Intent like this
Intent intent = new Intent(CurrentAct.this, NextAct.class);
intent.putExtra("dbData", intentData);
startActivity(intent);
You can retrieve the data from NextAct's onCreate() method like this :
String[] passedData = getIntent().getExtras().getStringArray("dbData");

Copying fields in iTextSharp 5.4.5.0

I was under the impression that it is now possible to copy AcroFields using PdfCopy. In the release notes for iText 5.4.4.0 this is listed as possible now. However, when I try to do so it appears all the annotations (I think I am using that term correctly, still fairly new to iText...) for the fields are stripped out. It looks like the fields are there (meaning I can see the blue boxes that indicate an editable field), but they are not editable. If I try to bring the PDF up in Acrobat I get a message saying that "there are no fields, would you like Acrobat to discover them?" and most are found and marked and fields properly (check boxes aren't, but the text fields are).
I assume there is an additional step somewhere along the lines to re-add the annotations to the PdfCopy object, but I do not see a way to get the annotations from the PdfReader. I also cannot seem to find any documentation on how to do this (since AcroFields were for so long not supported in PdfCopy most of what I find is along that vein).
Due to sensitivity I cannot provide a copy of the PDF's in question, but using an altered version of a test program used earlier you can see the issue with the following code. It should generate a table with some check boxes in the four right columns. If I use the exact same code with PdfCopyFields in the MergePdfs method instead of PdfCopy it works as expected. This code does not produce any text fields, but in my main project they are part of the original parent PDF that is used as a template.
(Sorry for the long example, it has been cherry picked from a much larger application. You will need a PDF with a field named "TableStartPosition" somewhere in it and update RunTest with the correct paths for your local machine to get this to work.)
Has the PdfCopy functionality not made it into iTextSharp yet? I am using version 5.4.5.0.

Please take a look at the MergeForms example. Your example is too long for me to read, but at first sight, I'm missing the following line:
copy.setMergeFields();
By the way, in MergeForms2, the fields are also renamed before the form is merged.
