Using holder variable inside an onClickListener method in ListViewAdapter
For the ListView I have made the holder object and everything. Initializing it if the convertView is null, else getting the tag.
I am programtically adding an ImageView to the List Row based on some conditions. That also I am adding in the holder.
Now the views are getting re-used. And all the views end up with the ImageView. I am suspecting that its because of the ImageView which I am adding dynamically.
How do I implement this ?
Thanks in advance.
static class ViewHolder{
TextView MessageText;
TextView Delivery_Date;
TextView Time;
RelativeLayout frame_layout;
ImageView image_view;
ProgressBar progress_bar;
}
@Override public View getView(final int position, View view, ViewGroup parent) {
View rowView;
rowView = view;
pos = position;
ViewHolder holder = null;
if(rowView==null)
{
rowView = context.getLayoutInflater().inflate(R.layout.message_row, null);
holder = new ViewHolder();
holder.MessageText = (TextView) rowView.findViewById(R.id.message_text);
holder.Delivery_Date = (TextView) rowView.findViewById(R.id.delivery_date);
holder.Time = (TextView) rowView.findViewById(R.id.time);
holder.frame_layout = (RelativeLayout) rowView.findViewById(R.id.frame_layout);
rowView.setTag (holder);
}
else
{
/* We recycle a View that already exists */
holder = (ViewHolder) rowView.getTag();
}
holder.image_view = new ImageView(context);
holder.image_view.setImageResource(R.drawable.ic_action_download);
holder.image_view.setMinimumHeight(40);
holder.image_view.setMinimumWidth(40);
final ProgressBar progress_bar = new ProgressBar(context, null, android.R.attr.progressBarStyleLarge);
if(// I want to add image condition)
{
final ViewHolder final_holder = holder;
holder.frame_layout.addView(holder.image_view);
holder.MessageText.setVisibility(View.GONE);
if(//I want to add ImageView)
{
Bitmap image = assigning image;
if(image!=null)
{ holder.image_view.getLayoutParams().width = intendedWidth ;
holder.image_view.getLayoutParams().height = intendedHeight ;
holder.image_view.setPadding(10,0,20,0);
holder.image_view.setImageBitmap(image);
}
else {
holder.image_view.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
final_holder.frame_layout.addView(progress_bar);
final_holder.frame_layout.removeView(final_holder.image_view);
Download_image download_image = new Download_image(context, MessageList.subscription_db, MessageList.service_id_clicked+"", MessageList.single_service_info.messages.get(position).MessageID);
download_image.execute();
}
});
}
}
else{
holder.image_view.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
final_holder.frame_layout.addView(progress_bar);
Download_image download_image = new Download_image(context, MessageList.subscription_db, MessageList.service_id_clicked+"", MessageList.single_service_info.messages.get(position).MessageID);
download_image.execute();
}
});
}
}
