JSONArray jarray;
try {
jarray = new JSONArray(result);
for(int i=0;i<jarray.length();i++){
HashMap<String, String> hm;
hm=new HashMap<String, String>();
JSONObject jobj=jarray.getJSONObject(i);
hm.put("Name",jobj.getString("name"));
hm.put("Phone",jobj.getString("phone"));
Log.d("name", jobj.getString("name"));
oslist.add(hm);
}
} catch (JSONException e) {
Toast.makeText(getBaseContext(), "Not getting result", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
Log.d("oslist", oslist.toString());
ListAdapter adapter = new SimpleAdapter(AutoSearchDetails.this, oslist,R.layout.listitem,new String[] { Name,Phone }, new int[] {
R.id.name,R.id.phone});
Log.d("adapter", adapter.toString());
listview.setAdapter(adapter);
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(
AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
Toast.makeText(AutoSearchDetails.this, "You Clicked at "+oslist.get(+arg2).get("name"), Toast.LENGTH_SHORT).show();
}
});
};
in log i do get "oslist" [{"name:fe","phone:32"}]
listitem.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/phone"
android:layout_width="match_parent"
android:layout_height="wrap_content"

</LinearLayout>
The problem is the value is not setting to the listview

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.Map;
public class MyAdapter extends BaseAdapter {
private final ArrayList mData;
public MyAdapter(Map<String, String> map) {
mData = new ArrayList();
mData.addAll(map.entrySet());
}
#Override
public int getCount() {
return mData.size();
}
#Override
public Map.Entry<String, String> getItem(int position) {
return (Map.Entry) mData.get(position);
}
#Override
public long getItemId(int position) {
// TODO implement you own logic with ID
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final View result;
if (convertView == null) {
result = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_adapter_item, parent, false);
} else {
result = convertView;
}
Map.Entry<String, String> item = getItem(position);
// TODO replace findViewById by ViewHolder
((TextView) result.findViewById(android.R.id.text1)).setText(item.getKey());
((TextView) result.findViewById(android.R.id.text2)).setText(item.getValue());
return result;
}
}
layout for this.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<TextView
android:id="#android:id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:id="#android:id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
And adapter in your code
public void showCinemas(HashMap<String, String> cinemas) {
MyAdapter adapter = new MyAdapter(cinemas);
list.setAdapter(adapter);
}

How to get certain children from an Expandable Listview?

I'm working on an Android application for placing orders, and I have an activity with an Expandable ListView, which I populate by parsing a JSON file. Now, in each row of the Expandable ListView I have an EditText Field for entering amount, and on a button click I would like to get all the children that have a value different than 0 in that EditText field, and put the data in a database (for the products and the amount that has been ordered).
I would need a help creating a function for getting those elements, since I've struggled with that recently.
Here is my code
Expandable List Adapter:
public class ExpandableListAdapter extends BaseExpandableListAdapter {
private Context _context;
private List<String> _listDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<Artikl>> _listDataChild;
public ExpandableListAdapter(Context context, List<String>
listDataHeader,
HashMap<String, List<Artikl>>
listChildData) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
}
#Override
public Object getChild(int groupPosition, int childPosititon) {
return
this._listDataChild.get(this._listDataHeader.get(groupPosition))
.get(childPosititon);
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
public int getChildAmount(int groupPosition, int childPosition,View
convertView) {
int kolicina;
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_item, null);
}
EditText amount = (EditText)
convertView.findViewById(R.id.editText);
kolicina=Integer.parseInt(amount.getText().toString());
return kolicina;
}
#Override
public View getChildView(int groupPosition, final int childPosition,
boolean isLastChild, View convertView,
ViewGroup
parent) {
final Artikl child = (Artikl) getChild(groupPosition,
childPosition);
final String childText = child.getNaziv();
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_item, null);
}
TextView txtListChild = (TextView) convertView
.findViewById(R.id.from_name);
txtListChild.setText(childText);
return convertView;
}
#Override
public int getChildrenCount(int groupPosition) {
return
this._listDataChild.get(this._listDataHeader.get(groupPosition))
.size();
}
#Override
public Object getGroup(int groupPosition) {
return this._listDataHeader.get(groupPosition);
}
#Override
public int getGroupCount() {
return this._listDataHeader.size();
}
#Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_group, null);
}
TextView lblListHeader = (TextView) convertView
.findViewById(R.id.lblListHeader);
lblListHeader.setTypeface(null, Typeface.BOLD);
lblListHeader.setText(headerTitle);
return convertView;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}}

And the Model (Artikl.java) has only Get and Set methods

In getChildView method of adapter add addTextChangedListener to edittext and in afterTextChanged method save enter text in database, if you want to get only numbers then restrict the keyboard number
mEtReference.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
if (editable.length() > 0) {
int value = Integer.parseInt(editable + "");
// save value
}
}
});

You not update your bannerdta to bannerAdapter, so bannerAdapter.notifyDataSetChanged() will not work.
you can add method updateData(Data banndata) in BannerAdapter.class
pubilc void updateData(Data banndata) {
blist.add(banndata);
notifyDataSetChanged();
}
and after call network request successfull, usebannerAdapter.updateData(banndata)

How to insert checkbox on custom listview

I am trying to add a checkbox in a customized listview but don't know how.
I have the following codes:
ListObject.java
package br.com.eduvm.xurrascalc;
public class ListObject {
private String texto;
private int iconeRid;
public ListObject() {
}
public ListObject(String texto, int iconeRid) {
this.texto = texto;
this.iconeRid = iconeRid;
}
public int getIconeRid() {
return iconeRid;
}
public void setIconeRid(int iconeRid) {
this.iconeRid = iconeRid;
}
public String getTexto() {
return texto;
}
public void setTexto(String texto) {
this.texto = texto;
}
}
ListAdapter.java
package br.com.eduvm.xurrascalc;
import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.ImageView;
import android.widget.TextView;
public class ListAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<ListObject> itens;
public ListAdapter(Context context, ArrayList<ListObject> itens) {
// Itens que preencheram o listview
this.itens = itens;
// responsavel por pegar o Layout do item.
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return itens.size();
}
public ListObject getItem(int position) {
return itens.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View view, ViewGroup parent) {
ListObject item = itens.get(position);
view = mInflater.inflate(R.layout.itens_lista, null);
((TextView) view.findViewById(R.id.text)).setText(item.getTexto());
((ImageView) view.findViewById(R.id.imagemview)).setImageResource(item.getIconeRid());
return view;
}
}
List.xml
<?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="horizontal" >
<LinearLayout

android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="5sp" >
<ImageView

How could I do to insert a checkbox in the items in this list?

This would be the layout for each individual row in your list
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/lstChkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lstText"
android:textSize="30px"
android:layout_weight="1" />
<ImageView
android:id="#+id/listImage"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
You main list activity layout will look something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"
android:choiceMode="multipleChoice"
/>
Your class which extends BaseAdapter getView method will somethings like this:
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vHolder = null;
if (convertView != null)
vHolder = (ViewHolder) convertView.getTag(); // convertView is been recycled
else {
convertView = (View) mInflater.inflate(R.layout.list_item, null); // Set content of new View with list_item.xml
vHolder = new ViewHolder();
vHolder.checkBox = ((CheckBox) convertView.findViewById(R.id.lstChkbox)); // Getting pointers
vHolder.textView = ((TextView) convertView.findViewById(R.id.lstText));
vHolder.imageView = ((ImageView) convertView.findViewById(R.id.listImage));
vHolder.checkBox.setOnCheckedChangeListener(this); // Setting Listeners
convertView.setTag(vHolder);
}
vHolder.checkBox.setId(position); // This is part of the Adapter APi
vHolder.textView.setId(position); // Do not delete !!!
vHolder.imageView.setId(position);
if (mItems.get(position).getChecked()) { // Setting parameters for the View from our mItems list
vHolder.checkBox.setChecked(true);
} else {
vHolder.checkBox.setChecked(false);
}
vHolder.textView.setText(mItems.get(position).getText());
vHolder.imageView.setImageDrawable(mItems.get(position).getmImage());
return convertView;
}
public static class ViewHolder {
CheckBox checkBox;
TextView textView;
ImageView imageView;
}
/*
* Ok for this test but Toast are going to show every time the row comes into View
*/
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Log.d(TAG, "Checked");
int position = buttonView.getId();
if (isChecked) {
mItems.get(position).setChecked(true);
Toast.makeText(context, mItems.get(position).getText(), Toast.LENGTH_LONG).show();
} else {
mItems.get(buttonView.getId()).setChecked(false);
}
}

Just add a checkbox to the layout itens_lista.xml.
Just adding a checkbox is easy. Do you want to do anything more to ti.

Add a CheckBox View to your custom row layout.

if(count<5){

#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(this,"ITem clicked", Toast.LENGTH_LONG).show();
}
}

I think you are using CustomAdapter to populate the listview..
If So then in getView() include the the button action:
public View getView(final int position, View convertView, ViewGroup parent)
{
View row=convertView;
FetchHolder holder=null;
if (row==null)
{
LayoutInflater inflater=getLayoutInflater();
row=inflater.inflate(R.layout.grid, parent, false);
holder=new FetchHolder(row);
row.setTag(holder);
}
else
{
holder=(FetchHolder)row.getTag();
}
holder.button.setOnClickListener(new OnClickListener()
{
public void onClick(View v) {
}
});
return row;
}
}
static class FetchHolder
{
private Button time=null;
FetchHolder(View row)
{
time=(Button)row.findViewById(R.id.timebutton);
}
