Let's say, I have two textviews, TextView A and B.
when I click on A, I need to change both textviews;
When I click on B, I need it to do something else.
I used the setTag(key,A); and setTag(key,B); The textView A changed correctly but the textView B is null. And when I click on B it works.
Here is my code :
public class CustomeAdapterHowComment extends ArrayAdapter<ItemsHowComment> {

Use
View view = v.getParent();
and then try to initialize views with view in onClick
You can set Tag
h.name.setOnClickListener(listener);
h.name.setTag(h.numoflike); // use setTag only once
h.numoflike.setOnClickListener(listener);
h.numoflike.setTag(h.name); // use setTag only once
Then in on click
public void onClick(View v) {
switch(v.getId())
{
case R.id.CommentName :
TextView tv1 = (Button) v.getTag();
TextView tv2 = (TextView) v;
tv1.setText("clicked");
tv2.setText("clicked");
break;
case R.id.CommentNumOfLike :
//do something
break;
}
}
Or in onClick Initialize yours views
View view = v.getParent();
TextView tv = view.findVIewById(R.id.CommentName);
TextView tv1 = view.findVIewById(R.id.CommentNumOfLike);
tv.setText("clicked");
tv1.setText("clicked");

I have a problem in Android, and Ive tried a couple of solutions, but nothing work.
When I scroll the list I get the exception:

view.setTag(holder);
}
else holder = (SecondViewHolder)view.getTag();
Specifically in view.getTag()
Don't store fields while views are recycled
Try this
#Override
public int getItemViewType(int position) {
String tipo = mercadorias.get(position).getTipo();
if (tipo.equals("1"))
return 0;
else
return 1;
}
Also, this doesn't make sense
if(mercadorias.size() > 1){
mercadoria = mercadorias.get(position);
}else{
mercadoria = mercadorias.get(0);
}
If the Arraylist is empty, this will throw an exception, but if the size is equal to one, then the position should already be the first element
I'm using ExpandapbeListView its work perfect all expand and collapse but I just want to update only particular child item here when I click on plus value should be update in EditText and I don't want to use notifyDatasetChanged() Just want to update only particular field and also i should able to update EditText directly. It can have multiple child item.
Ex: Colgate may have multiple child Item like 100gm,200gm,300gm
So when I click on Plus It should able to get Id of EditText and Update Quantity

listview is working properly
i just inflate cardview in listview.
when using this code image cannot displaying. only dispaly last image in list view
params.height = totalHeight
+ (myListView.getDividerHeight() * (myListAdapter
.getCount() - 1));
my problem is: In listview only displaying last image
check this image:
Try adding your ImageView to Holder class and use like viewholder.img.setImageBitmap(new LoadImage().execute(urll)) and change the return type to Bitmap
Use BaseAdapter instead of ArrayAdapter. Load and show image with UIL, Picasso or other image loader library.

I am trying to build a demo chatting App.I want to show the messages with section headers as Dates like "Today","Yesterday","May 21 2015" etc.I have managed to achieve this but since the new View method gets called whenever I scroll the list.The headers and messages get mixed up.
For simplicity, I have kept the header in the layouts itself and changing its visibility(gone and visible) if the date changes.
Can you help me out with this? Let me know if anyone needs any more info to be posted in the question.

I have a list with ImageView and TextView. I read a scann time and for the specified position of textview has to be set. This is done i a right way, but after srolling down and then up another textview in Listview is set. I am seeing that this is not new, but I could not solve this problem.Any idea?? BaseAdapter is in the following. I tried for more then a week but no solution
