I am making a custom listview with image and some text. I have used this tutorial http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/.Now I want to select a row item from listview and wants to display on other activity.I use onClickListener for this and pass data using Intent.But on other activity nothing is displaying.
This is my CustomListAdapter Class
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import com.android.volley.toolbox.ImageLoader;
import com.android.volley.toolbox.NetworkImageView;
import java.util.List;
import aquib.lathesis.volleylistview.R;
import aquib.lathesis.volleylistview.SingleItemView;
import aquib.lathesis.volleylistview.app.AppController;
import aquib.lathesis.volleylistview.model.Movie;
public class CustomListAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<Movie> movieItems;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public CustomListAdapter(Activity activity, List<Movie> movieItems) {
this.activity = activity;
this.movieItems = movieItems;
}
@Override
public int getCount() {
return movieItems.size();
}
@Override
public Object getItem(int location) {
return movieItems.get(location);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_row, null);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView item_image = (NetworkImageView) convertView
.findViewById(R.id.item_image);
TextView item_name = (TextView) convertView.findViewById(R.id.item_name);
TextView item_category = (TextView) convertView.findViewById(R.id.item_category);
TextView item_serve = (TextView) convertView.findViewById(R.id.item_serve);
TextView item_price = (TextView) convertView.findViewById(R.id.item_price);
// getting movie data for the row
Movie m = movieItems.get(position);
// thumbnail image
item_image.setImageUrl(m.getItem_image(), imageLoader);
// item name
item_name.setText(m.getItem_name());
// item category
item_category.setText(m.getItem_category());
// item serve
item_serve.setText(m.getItem_serve());
// item price
item_price.setText(String.valueOf(m.getItem_price()));
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Movie p = movieItems.get(position);
Intent i = new Intent(activity.getApplicationContext(), SingleItemView.class);
i.putExtra("itemimage", p.getItem_image());
i.putExtra("itemname", p.getItem_name());
i.putExtra("itemcategory", p.getItem_category());
i.putExtra("itemserve", p.getItem_serve());
i.putExtra("itemprice",String.valueOf(p.getItem_price()));
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
activity.getApplicationContext().startActivity(i);
}
});
return convertView;
}
}
This is my SingleItemView Activity
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import com.android.volley.toolbox.ImageLoader;
import com.android.volley.toolbox.NetworkImageView;
import aquib.lathesis.volleylistview.app.AppController;
import aquib.lathesis.volleylistview.model.Movie;
public class SingleItemView extends Activity{
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
private static String TAG;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Get the view from singlelistview.xml
setContentView(R.layout.singlelistview);
try{
Intent i = getIntent();
//Get the result of item image
i.getStringExtra("itemimage");
//Get the result of item name
i.getStringExtra("itemname");
//Get the result of item category
i.getStringExtra("itemcategory");
//Get the result of item serve
i.getStringExtra("itemserve");
//Get the result of item price
i.getStringExtra("itemprice");
//Locate the image view
NetworkImageView itemImage = (NetworkImageView) findViewById(R.id.itemImage);
//Locate the text view
TextView itemName = (TextView) findViewById(R.id.itemName);
TextView itemCategory = (TextView) findViewById(R.id.itemCategory);
TextView itemServe = (TextView) findViewById(R.id.itemServe);
TextView itemPrice = (TextView) findViewById(R.id.itemPrice);
Movie m = new Movie();
itemImage.setImageUrl(m.getItem_image(), imageLoader);
itemName.setText(m.getItem_name());
itemCategory.setText(m.getItem_category());
itemServe.setText(m.getItem_serve());
itemPrice.setText(String.valueOf(m.getItem_price()));
} catch (Exception e){
Log.e(TAG, e.getMessage());
}
}
}
This is my Data File
package aquib.lathesis.volleylistview.model;
public class Movie {
private String item_image, item_name, item_category, item_serve;
private double item_price;
public Movie(){
}
public Movie(String item_image, String item_name, String item_category, String item_serve, double item_price) {
this.item_image = item_image;
this.item_name = item_name;
this.item_category = item_category;
this.item_serve = item_serve;
this.item_price = item_price;
}
public String getItem_image() {
return item_image;
}
public void setItem_image(String item_image) {
this.item_image = item_image;
}
public String getItem_name() {
return item_name;
}
public void setItem_name(String item_name) {
this.item_name = item_name;
}
public String getItem_category() {
return item_category;
}
public void setItem_category(String item_category) {
this.item_category = item_category;
}
public String getItem_serve() {
return item_serve;
}
public void setItem_serve(String item_serve) {
this.item_serve = item_serve;
}
public double getItem_price() {
return item_price;
}
public void setItem_price(double item_price) {
this.item_price = item_price;
}
}
