Imageview getting automatically changed on scroll listview

I am new to android and facing one very comman problem of listview i googled alot but did'nt found anything usefull for my case.Hope you people show me the right direction.Whenever I am changing my image from "plus" to "tick" on click my last item image also got automatically changed on scroll.
My list_comapare_product XMl :-
<?xml version="1.0" encoding="utf-8"?>

Thanks.

You need to keep track of which items have been "ticked". I copied your adapter and made necessary changes. You can just copy-paste the code and it should work.

//Already ticked, set to plus
viewHolder.imgadd.setImageDrawable(activity.getResources().getDrawable(R.drawable.plus));

} else {
tickedItems.add((Integer)v.getTag());
viewHolder.imgadd.setImageDrawable(activity.getResources().getDrawable(R.drawable.tick));
}
}
});
if(tickedItems.contains(position))
viewHolder.imgadd.setImageDrawable(activity.getResources().getDrawable(R.drawable.tick));

viewHolder.imgadd.setImageDrawable(activity.getResources().getDrawable(R.drawable.plus));
return convertView;
}
static class ViewHolder {

ImageView imgProduct, imgadd;

}
As an extra, don't use ImageView.setImageResource() as it is inefficient.
Quote from Android docs about ImageView.setImageReource()
This does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup. If that's a concern, consider using setImageDrawable(android.graphics.drawable.Drawable) or setImageBitmap(android.graphics.Bitmap) and BitmapFactory instead.

now when i run program
fragment that fill with customadapter work very good
but fragment that filled by articlesadapter have below error
java.lang.ClassCastException: ir.monocode.az.ArticlesModel cannot be cast to ir.monocode.az.CatsModel
how i must solve my problem?
can you help me please?
thank you

You can solve with polymorphism. Replace the failing declaration (the one your cast error comes from) with the Interface BaseAdapter
Something like this (your relevant code wasn't posted, so this is just a guess)
CatsModel it = retrieveMyCustomAdapter();
becomes
BaseAdapter it = retrieveMyCustomAdapter();
A more formal approach would be to declare an abstract class extending BaseAdapter, and make both CatsModel and ArticlesModel inherit from this new class.

Get different multiple image views in a list view

I have been trying to implement a list view which has five image views in a single row of a list view. I found that it can be done with layout inflater but since I am new to android I could not exactly get how to make the best use of it. I want to get a view of this sort:
L,S,D,A,E are images and it should change accordingly for different users in the list view according to the data provided dynamically. Can anybody please help me with the code snippet for this, or just give me an idea on how to implement it?

Okay so your list view should inflate a layout of this type:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:id="#+id/layoutContainer" >
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/iv1" />
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/iv2" />
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/iv3" />
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/iv4" />
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/iv5" />
</LinearLayout>
Save it to row.xml located in your layout folder.
Next implement this in your activity's onCreate() method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CustomAdapter myAdapter = new CustomAdapter(getApplicationContext());
ListView mainListView = (ListView) findViewById(R.id.lv);
mainListView.setAdapter(myAdapter);
}
Finally, you need to create the CustomAdapter.java class, like this:
import android.content.Context;
import android.graphics.Bitmap;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
public class CustomAdapter extends BaseAdapter {
private Bitmap[][] data;
private int count;
private Context context;
public CustomAdapter(Context context) {
this.context = context;
data = new Bitmap[100][];
count = 0;
}
#Override
public int getCount() {
return count;
}
#Override
public Bitmap[] getItem(int position) {
// TODO Auto-generated method stub
return data[position];
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View adapterView = convertView;
if (adapterView == null) {
adapterView = inflater.inflate(R.layout.row, null);
}
ImageView imageView = (ImageView) adapterView.findViewById(R.id.iv1);
imageView.setImageBitmap(data[position][0]);
//Repeat the last two steps for all five images, changing the last index accordingly
return adapterView;
}
public void addBitmapArray (Bitmap[] newValue) {
data[++count] = newValue;
}
}

In row of the list add a linear layout LinearLayout1 then do something like fallowing in your adapter add dynamically images to the list item..
public View getView(final int position, View convertView, ViewGroup parent)
{
// System.out.println(" inside KeyvalueAdapter..");
ViewHolder holder = null;
if (convertView == null)
{
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.new_row, null);
holder = new ViewHolder();
holder.tv_title = (TextView) convertView.findViewById(R.id.titleTextView);
ImageView imageView = new ImageView(context);
imageView.setImageResource(resId);
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.LinearLayout1);
linearLayout.addView(imageView);
convertView.setTag(holder);
}
else holder = (ViewHolder) convertView.getTag();
holder.tv_title.setText(notifList.get(position));
return convertView;
}

If you want to load different image you have to extend your listview adapter:
example if i understand correctly your question.

You have to write your own xml with 5 imageviews

Android ListView row color

I'm trying to change the row color of my listView in customAdapter. There's an array of integer that include 0 and 1, I'm trying to read from the array and change the color of rows like this:
0 = white
1 = yellow
but it shows a yellow color in all rows.
This is my CustomAdapter:
package com.example.test;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.graphics.Color;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class CustomAdapter extends ArrayAdapter<RowItem> {
ArrayList<Integer> test;
Context context;
public CustomAdapter(Context context, int resourceId, List<RowItem> items) {
super(context, resourceId, items);
this.context = context;
}
/* private view holder class */
private class ViewHolder {
ImageView imageView;
TextView txtTitle;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
RowItem rowItem = getItem(position);
SqliteHelper checkFav = new SqliteHelper(context);
checkFav.open();
test = checkFav.getFavForList();
checkFav.close();
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.row_layout, null);
holder = new ViewHolder();
holder.txtTitle = (TextView) convertView.findViewById(R.id.pTxt);
holder.imageView = (ImageView) convertView.findViewById(R.id.icon);
convertView.setTag(holder);
} else
holder = (ViewHolder) convertView.getTag();
int color0 = Color.YELLOW;
int colorDefault = Color.WHITE;
switch (test.get(position)){
case 0:
convertView.setBackgroundColor(colorDefault);
break;
case 1:
convertView.setBackgroundColor(color0);
}
holder.txtTitle.setText(rowItem.getTitle());
holder.imageView.setImageResource(rowItem.getImageId());
return convertView;
}
}
And this is my row_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<ImageView
android:id="#+id/icon"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="5dp"
android:src="#drawable/active_icon" />
<TextView
android:id="#+id/pTxt"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textSize="20sp"
android:gravity="right"/>
</LinearLayout>
Thanks in advance.

getView() is called for each row in a list so you should not loop over all items in test but only handle the one denoted by position and you should do that after (not in) the if (convertView == null) block.
Edit:
getView() should do the following things:
Check if convertView isn't null (if it is, create a new View as you did)
Check if convertView is of the right type (this only matters if more than one kind of View is used in the list which is not the case here). If the type is wrong, create a new View.
Now we have a valid View for the list row.
Retrieve the data which affects how to display this row. In your case this would be the result of test.get(position). The position is the number of the requested row (starting with 0 at the top of the ListView).
Adjust the View according to your data (you did this in the for-loop but you should do it only once for the requested entry at position).
Return the View
In more complex situations you may have to do the third step before the second but not here.

Fast solution (not very nice code, but works):
#Override
public int getItem(int position){
return test.get(position);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
int color0 = ....
int color1 = ....
int colorDefault = ...
switch (test.get(position)) {
case 0:
convretview.setBackgroundColor(color0);
break;
case 1:
convretview.setBackgroundColor(color1);
break;
default:
convretview.setBackgroundColor(colorDefault);
}
...
}

You are not setting the text in TextView in case convertView is null.
Instead of:
if(convertView == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.custom, null);
TextView tv = (TextView)v.findViewById(R.id.name);
Typeface myTYpe = Typeface.createFromAsset(context.getAssets(), "solaiman-lipi.ttf");
tv.setTypeface(myTYpe);
holder.RssTitle = tv;
v.setTag(holder);
}
else{
holder = (RssHolder) v.getTag();
RssItem p = listItems.get(position);
holder.RssTitle.setText(p.getTitle());
}
Use
ViewHolder holder;
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(R.layout.custom, null);
holder = new ViewHolder();
Typeface typeface = Typeface.createFromAsset(context.getAssets(), "solaiman-lipi.ttf")
holder.rssTitle = (TextView) convertView.findViewById(R.id.name);
holder.rssTitle.setTypeface(typeface);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.rssTitle.setText(listItems.get(position).getTitle());
return convertView;
