How can I Pass Name & Country from Entry Item

I am developer a Apps which contain Various Name & Country List. I want to pass Employee Name & Country name to another activity on click on Child Item of Expandable ListView.

In the Employee_List activity , you can access the data through index of child and group obtaining from ChildClickListener
myList.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView arg0, View arg1, int arg2,
int arg3, long arg4) {
// TODO Auto-generated method stub
//Here You can access the child data by
final EntryItem country = (EntryItem) listAdapter .getChild(arg2, arg3);
//From here you can pass the data through Intent

How to pass different intent Extras in a custom ListView in android?

here I have a String array of rootCategoryID and a String categoryID.
On my custom ListView I want to pass different IDs for each of the rows.
But I can't make it work! Here's my code:
package ir.zabardast.onlinemarket;
import android.app.ListActivity;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
public class Main extends ListActivity {
String[] rootCategoryName = new String[6];
String[] rootCategoryImage = new String[6];
String[] rootCategoryID = new String[6];
int categoryCount;
String categoryID = "0";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(true){
setContentView(R.layout.activity_main);
HandleXML hxml = new HandleXML();
String url = "http://karakaal.com/market/category.xml";
String object = "category";
hxml.fetchXML(url, object);
while(hxml.parsingComplete);
categoryCount = hxml.getCategories().size();
for (int i = 0; i < categoryCount; i++) {
if(hxml.getCategories().get(i).getParentId() == 0){
rootCategoryName[i] = hxml.getCategories().get(i).getName();
}
}
for (int i = 0; i < categoryCount; i++) {
if(hxml.getCategories().get(i).getParentId() == 0){
rootCategoryImage[i] = hxml.getCategories().get(i).getImage();
}
}
for (int i = 0; i < categoryCount; i++) {
if(hxml.getCategories().get(i).getParentId() == 0){
rootCategoryImage[i] = hxml.getCategories().get(i).getId();
}
}
setListAdapter(new MyAdapter(this,
android.R.layout.simple_list_item_1,
R.id.listName,
rootCategoryName));
ListView listView = getListView();
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View view, int i, long l) {
Intent intent = new Intent(Main.this, CategoryList.class);
intent.putExtra("categoryID", categoryID);
startActivity(intent);
}
});
} else if (!checkWifi()) {
setContentView(R.layout.wifi_check);
}
}
private class MyAdapter extends ArrayAdapter<String>{
public MyAdapter(Context context, int resource, int textViewResourceId,
String[] rootCategoryName) {
super(context, resource, textViewResourceId, rootCategoryName);
// TODO Auto-generated constructor stub
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.list, parent, false);
String[] products = rootCategoryName;
ImageView iv = (ImageView) row.findViewById(R.id.listImage);
TextView tv = (TextView) row.findViewById(R.id.listName);
tv.setText(products[position]);
int loader = R.drawable.ic_launcher;
ImageLoader imgLoader = new ImageLoader(getApplicationContext());
String baseURL = "http://karakaal.com/market/";
imgLoader.DisplayImage(baseURL + rootCategoryImage[position], loader, iv);
categoryID = rootCategoryID[position];
return row;
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public boolean checkWifi()
{
ConnectivityManager conman = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
boolean wifi = conman.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting();
if (wifi)
return true;
else
return false;
}
}
As you can see I use a variable to set categoryID in my private class
I want to pass rootCategoryID of each row by an Intent to the next activity when each row is clicked

you can get categoryID by position of ListView clicked
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View view, int i, long l) {
Intent intent = new Intent(Main.this, CategoryList.class);
intent.putExtra("categoryID", rootCategoryID[i]);//here CategoryId
startActivity(intent);
}
});

Dialog file to update list rows does not work / OnItemLongClick

I managed to get Dialog to show up on the long click by implementing this code:
ListView list = getListView();
list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
});
Unfortunately, when the dialog opens and prompts for new text input, when clicked ok, no changes are made to the list.
Here is the Dialog file:
package com.example.classorganizer;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
class EditListItemDialog extends Dialog implements View.OnClickListener {
private View editText;
public EditListItemDialog(Context context) {
super(context);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
View btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}
#Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
}
Here is the file containing list:
package com.example.classorganizer;
import java.util.ArrayList;
import android.app.ListActivity;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;

MyDB dba;
DiaryAdapter myAdapter;
private class MyDiary{
public MyDiary(String t, String c){
title=t;
content=c;
ListView list = getListView();
list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
});
}
public String title;
public String content;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
dba = new MyDB(this);
dba.open();
setContentView(R.layout.fragment_monday);
super.onCreate(savedInstanceState);

this.setListAdapter(myAdapter);
}
private class DiaryAdapter extends BaseAdapter {

public DiaryAdapter(Context context) {

getdata();
}
public void getdata(){

startManagingCursor(c);
if(c.moveToFirst()){
do{
String title =
c.getString(c.getColumnIndex(Constants.TITLE_NAME));
String content =
c.getString(c.getColumnIndex(Constants.CONTENT_NAME));
MyDiary temp = new MyDiary(title,content);
fragment_monday.add(temp);
} while(c.moveToNext());
}
}
#Override
public int getCount() {return fragment_monday.size();}
public MyDiary getItem(int i) {return fragment_monday.get(i);}
public long getItemId(int i) {return i;}
public View getView(int arg0, View arg1, ViewGroup arg2) {
final ViewHolder holder;
View v = arg1;
if ((v == null) || (v.getTag() == null)) {
v = mInflater.inflate(R.layout.diaryrow, null);
holder = new ViewHolder();
holder.mTitle = (TextView)v.findViewById(R.id.name);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
holder.mdiary = getItem(arg0);
holder.mTitle.setText(holder.mdiary.title);
v.setTag(holder);
return v;
}
public class ViewHolder {
MyDiary mdiary;
TextView mTitle;
}
}
/** Called when the user clicks the Edit button */
public void visitDiary(View view) {
Intent intent = new Intent(this, Diary.class);
startActivity(intent);
}
/** Called when the user clicks the back button */
public void visitSchedule(View view) {
Intent intent = new Intent(this, DisplayScheduleScreen.class);
startActivity(intent);
}
}
Here is an xml file for dialog:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout4"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" >
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK" />
</RelativeLayout>
</LinearLayout>
I don't understand why the rows are not being updated with data entered through Dialog file...

#Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
You are getting the value from TextView of the dialog ,have u added the data to the list.
Update the data to the list
fragment_monday.add(((TextView) editText).getText().toString());

is it possible to edit field from listview on long click action?

Is it possible to have such functionality in android? When user longclicks row in a list popup window opens with option to edit content?

Yes it is. First of all you need to create your own Dialog with appropriate xml:
private static class EditListItemDialog extends Dialog implements View.OnClickListener {
private EditText editText;
public EditListItemDialog(Context context) {
super(context);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
Button btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}
#Override
public void onClick(View v) {
editText.getText().toString();//here is your updated(or not updated) text
dismiss();
}
}
Then add listener at setOnLongClickListener:
ListView listView = new ListView(this);
listView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
new EditListItemDialog(v.getContext()).show();
return true;
}
});
Finally you need to update data in your ListView. The right way is to update Adapter of your list view which finally will update ListView.

Ok, I managed to make Dialog file as in your example:
package com.example.classorganizer;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
class EditListItemDialog extends Dialog implements View.OnClickListener {
private View editText;
public EditListItemDialog(Context context) {
super(context);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
View btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}
#Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
}
I created an xml file for Dialog file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK" />
</LinearLayout>
Then I updated my Display List file with this code:
ListView listView = new ListView(Monday.this);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
});
And here is full file that displays list of rows to be edited upon Long Click:
import java.util.ArrayList;
import android.app.ListActivity;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;
import com.cookbook.data.Constants;
import com.cookbook.data.MyDB;
public class Monday extends ListActivity {
private static final int MyMenu = 0;
MyDB dba;
DiaryAdapter myAdapter;
private class MyDiary{
public MyDiary(String t, String c){
title=t;
content=c;
}
public String title;
public String content;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
dba = new MyDB(this);
dba.open();
setContentView(R.layout.fragment_monday);
super.onCreate(savedInstanceState);
myAdapter = new DiaryAdapter(this);
this.setListAdapter(myAdapter);
}
private class DiaryAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<MyDiary> fragment_monday;
public DiaryAdapter(Context context) {
mInflater = LayoutInflater.from(context);
fragment_monday = new ArrayList<MyDiary>();
getdata();
//new code below
ListView listView = new ListView(Monday.this);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
}); //end of new code
}
public void getdata(){
Cursor c = dba.getdiaries();
startManagingCursor(c);
if(c.moveToFirst()){
do{
String title =
c.getString(c.getColumnIndex(Constants.TITLE_NAME));
String content =
c.getString(c.getColumnIndex(Constants.CONTENT_NAME));
MyDiary temp = new MyDiary(title,content);
fragment_monday.add(temp);
} while(c.moveToNext());
}
}
#Override
public int getCount() {return fragment_monday.size();}
public MyDiary getItem(int i) {return fragment_monday.get(i);}
public long getItemId(int i) {return i;}
public View getView(int arg0, View arg1, ViewGroup arg2) {
final ViewHolder holder;
View v = arg1;
if ((v == null) || (v.getTag() == null)) {
v = mInflater.inflate(R.layout.diaryrow, null);
holder = new ViewHolder();
holder.mTitle = (TextView)v.findViewById(R.id.name);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
holder.mdiary = getItem(arg0);
holder.mTitle.setText(holder.mdiary.title);
v.setTag(holder);
return v;
}
public class ViewHolder {
MyDiary mdiary;
TextView mTitle;
}
}
/** Called when the user clicks the Edit button */
public void visitDiary(View view) {
Intent intent = new Intent(this, Diary.class);
startActivity(intent);
}
/** Called when the user clicks the back button */
public void visitSchedule(View view) {
Intent intent = new Intent(this, DisplayScheduleScreen.class);
startActivity(intent);
}
}
There you can see where I put the new code. Unfortunately, upon long click row is not being updated. I mean, the dialog file seems that is not being launched. Is it because I put the code in the wrong place or am I missing something else?
