So this works as long as all EditTexts fits on the screen. Firoz Jaroli Firoz Jaroli 5 5 silver badges 10 10 bronze badges. Too bad this does not work when the RecyclerView recycles some views.Android S9E9 : RecyclerView with ExpandableLayout
The inner class must be referenced by: MyPersonalAdapter. Or the adapter class should be imported. Implement a addTextChangedListener inside bindview method in the recyclerview adapter. This should be enough.It contains two views one is parent view and other is child view. Parent is visible by default but the child view has to be expanded and collapsed.
It will expand when we click on parent view. This feature is quite similar to the ExpandableListView in Android. Since it is an old one, it does not perform well according to our requirement.
After adding the library, we have to add some Java classes with the help of this library like Adapter, Model, and View holders.
So here in this example we will show Movie category as a parent and movies according to the category are a child. Create this XML file for creating the view of movie category. Add the code inside LinearLayout. Create this class and extend it with ParentViewHolder.
It is a class which binds the view. Here we take the reference of MovieCategory view and set the properties when it is expanded and collapsed.
Now, set the properties for expand and collapse of arrow image and its rotation accordingly by implementing two methods setExpanded and onExpansionToggled. Create this custom Adapter class which extends ExpandableRecyclerAdapter. One of which is for parent and the other for the child. It is in our Main Activity that we pass the data, set the adapter and take the reference of Recycler View. We can save the expanded and collapsed state of items in our Recycler View during our device configuration changes.
Other things and also we can store the state of same. Like this, we can save the state. This feature is mainly used in many applications. We can customize it according to the requirement. It is the same as ExapandableListView but has some new features added. An interesting functionality of Android, it is frequently used by the developers. Android ExpandableListview. HEY thats nice tutorial but can u explain me how do i get the child position in the fragments class and how to make like only one to be expandable if i have 3 views i need only one among them to be opened first please help me put.
You have no need of reference of Fragment view to get its components in Activity. As you can directly access layout components of a Fragment in parent Activity. Simply you can access any component by this findViewById R. May be by using list or array. Please suggest. Hi Yaka, Thank you for asking us and reading our blogs.!!

I have a RecyclerView that has many cards that hold 4 EditText. When I input values in one EditText of one card, it fills the same value in random cards. Surprisingly it does not jump EditText s for example:. If I input values in edittext1 of card1 it would fill the same value into edittext1 in card8 and if I change the value in card8 it will change the value back in card1. Could someone please tell me why this is happening. That happens because the views inside a RecyclerView are being recycled.
Inside the onBindViewHolder you need to set the specific texts to the EditTexts at the specific position. Initialize your Views inside the ViewHolder and add the TextWatchers there as the whole philosophy of the RecyclerView is to reuse the views :. You updated the data without notifying the adapter. This could create inconsistencies.
So after the data is changed you should call notifyItemChanged. One more suggestion I have is to reuse the code so you won't have to copy paste so much and fix in many places for example, all of your TextWatcher objects are basically the same. Learn more.

Here the name and balance fields are coming from two different arrays. What I need is, here each row has an EditText field. I need to access each EditText on each row. And get values from it. Is it possible? I tried a lot. I didn't get it.
I think you are looking for a callback, which means whenever a number on one of the EditTexts is changed you want the total number change too.
So first of all you need to add an interface. In the onBindViewHolder of your Adapter you need to set a listener for text change and tell the fragment using onEditTextChanged object. Add this array to your GroupCollectionFragment so you can save the values in your fragment and use them whenever you want them.

April 20, September 24, November 11, The data is getting displayed correctly, but I am not able to input any characters into the edittextboxes. The post is very good and you have explained it very well. I am trying with multiple edittextboxes using your example, however i find that the edittextboxes are not receiving focus.
I have implemented textwatcher for each edittextboxes in the Viewholder class. Please share your inputs. I guess you are trying to add two or more edittexts in one single row. Are you able to input text in one single edittext among all or non of edittext is receiving focus?
Then also add code in adapter class for your second edittext same as i have added for first edittext.

I've tried to get it working for the past 3 days to no avail. I tried using the AdvancedReyclerview library but to a beginner like me, it was a giant mess of things that didn't make sense especially when passing in the data. I copied and pasted files that I needed to get a minimal working version but I had no idea how to pass my data into the recyclerview and how to update it with the newly selected value. Any thoughts on that? You can check my library in here. You can easily achieve it with this librarythere is a full example here.
