package com.jsupport.listviewimages;

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.ImageView;
import android.widget.TextView;

public class ItemListBaseAdapter extends BaseAdapter {
 private static ArrayList<ItemDetails> itemDetailsrrayList;
 
 private Integer[] imgid = {
   R.drawable.p1,
   R.drawable.bb2,
   R.drawable.p2,
   R.drawable.bb5,
   R.drawable.bb6,
   R.drawable.d1
   };
 
 private LayoutInflater l_Inflater;

 public ItemListBaseAdapter(Context context, ArrayList<ItemDetails> results) {
  itemDetailsrrayList = results;
  l_Inflater = LayoutInflater.from(context);
 }

 public int getCount() {
  return itemDetailsrrayList.size();
 }

 public Object getItem(int position) {
  return itemDetailsrrayList.get(position);
 }

 public long getItemId(int position) {
  return position;
 }

 public View getView(int position, View convertView, ViewGroup parent) {
  ViewHolder holder;
  if (convertView == null) {
   convertView = l_Inflater.inflate(R.layout.item_details_view, null);
   holder = new ViewHolder();
   holder.txt_itemName = (TextView) convertView.findViewById(R.id.name);
   holder.txt_itemDescription = (TextView) convertView.findViewById(R.id.itemDescription);
   holder.txt_itemPrice = (TextView) convertView.findViewById(R.id.price);
   holder.itemImage = (ImageView) convertView.findViewById(R.id.photo);

   convertView.setTag(holder);
  } else {
   holder = (ViewHolder) convertView.getTag();
  }
  
  holder.txt_itemName.setText(itemDetailsrrayList.get(position).getName());
  holder.txt_itemDescription.setText(itemDetailsrrayList.get(position).getItemDescription());
  holder.txt_itemPrice.setText(itemDetailsrrayList.get(position).getPrice());
  holder.itemImage.setImageResource(imgid[itemDetailsrrayList.get(position).getImageNumber() - 1]);

  return convertView;
 }

 static class ViewHolder {
  TextView txt_itemName;
  TextView txt_itemDescription;
  TextView txt_itemPrice;
  ImageView itemImage;
 }
}



ListViewImagesActivity





package com.jsupport.listviewimages;

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class ListViewImagesActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

ArrayList<ItemDetails> image_details = GetSearchResults();

final ListView lv1 = (ListView) findViewById(R.id.listV_main);
lv1.setAdapter(new ItemListBaseAdapter(this, image_details));

lv1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
Object o = lv1.getItemAtPosition(position);
ItemDetails obj_itemDetails = (ItemDetails)o;
Toast.makeText(ListViewImagesActivity.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show();
} 
});
}

private ArrayList<ItemDetails> GetSearchResults(){
ArrayList<ItemDetails> results = new ArrayList<ItemDetails>();

ItemDetails item_details = new ItemDetails();
item_details.setName("Pizza");
item_details.setItemDescription("Spicy Chiken Pizza");
item_details.setPrice("RS 310.00");
item_details.setImageNumber(1);
results.add(item_details);

item_details = new ItemDetails();
item_details.setName("Burger");
item_details.setItemDescription("Beef Burger");
item_details.setPrice("RS 350.00");
item_details.setImageNumber(2);
results.add(item_details);

item_details = new ItemDetails();
item_details.setName("Pizza");
item_details.setItemDescription("Chiken Pizza");
item_details.setPrice("RS 250.00");
item_details.setImageNumber(3);
results.add(item_details);

item_details = new ItemDetails();

item_details.setItemDescription("Chicken Burger");
item_details.setPrice("RS 350.00");
item_details.setImageNumber(4);
results.add(item_details);

item_details = new ItemDetails();
item_details.setName("Burger");
item_details.setItemDescription("Fish Burger");
item_details.setPrice("RS 310.00");
item_details.setImageNumber(5);
results.add(item_details);

Thanks. Helped a lot.

Chathura Wijesinghe said...

It is pleasure to help you

Somalifood said...

Great Example but I have a question:
How Do I start a 'New Activity' when each item is clicked instead of showing text?

Thanks

Chathura Wijesinghe said...

Create activity called SubmenuActivity and you will be able to pass selected item value to new Activity

// place this in onItemClick()

//Starting a new Intent
Intent nextScreen = new Intent(getApplicationContext(),SubmenuActivity.class);

//Sending data to another Activity
nextScreen.putExtra("subcat",obj_itemDetails.getName());
//Start SubmenuActivity Activity
startActivity(nextScreen);



Getting value from SubmenuActivity Activity , past below code inside the onCreate() of SubmenuActivity


Intent intent = getIntent();
// Receiving the Data
String subcat = intent.getStringExtra("subcat");

I will explain in-detail my next post ....

Somalifood said...

Thank you so much Chathura it worked! How about if I want each item 'when clicked' to start a different Activity? e.g: SubmenuActivity1, SubmenuActivity2, SubmenuActivity3 etc. Sorry if I'm asking too much am new to Programming.

Chathura Wijesinghe said...

You can not create Activity dynamically.

BHARAT BHAGAT said...

Hi Chathura your project helped me in creating a custom listview for myself but I have a confsion where in the code/xml we are assigning that xyz values will be for a particular item in list...as far as I understand it must be by setTag() but I need a little more explanation about that.
Thanks

Chathura Wijesinghe said...

Amit Suri said...

Great Post Brother, i have tried to fetch selected listview item data to another activity and i am able to fetch text data but not able to fetch image, please add some code for the same also...Thanks

Chathura Wijesinghe said...

Thank you Amith.
pass the image id to another activity then you will be able to fetch the image.

Amit Suri said...

bro, could you please write few lines of code for me, because i have tried to pass but still not getting image in another activity....Thanks again

Chathura Wijesinghe said...

Sorry, late to reply

you can pass the image ID using following code

ItemDetails obj_itemDetails = (ItemDetails)o;

int image_id = obj_itemDetails.getImageNumber();

image_id will refer to your R.drawable.p1

Amit Suri said...

Thanks, brother i have tried it and getting the image.
