How to remove or change Recyclerview footer?

I am using this EndlessRecyclerView.java class to add footer or load more view to the RecyclerView. I have set a footer using the setProgressView() of the EndlessRecyclerView.java i.e.
mRecyclerView.setProgressView(R.layout.recyclerview_footer_layout);
Now after a specific situation, say after a network timeout, I want to change the TextView value in footer. But I am unable to do so using the follwing code:
View progressView = inflater.inflate(R.layout.recyclerview_footer_layout, null);
progressViewText = (TextView) progressView.findViewById(R.id.loadMoreText);
What is wrong here?

Using Adapter and Item Holder, Hide views from List View

I want to show my text view as shown in Image Below, for which i have to
remove other Views (as I have taken a Text View, Image View and a Video View

itemHolder.textViewMessage = (TextView) convertView
.findViewById(R.id.messageDetail);
if (itemHolder.textViewMessage != null && messageBean.getMessage()!=null)
{
itemHolder.textViewMessage.setText(messageBean.getMessage()); // here i am showing my text messages.
itemHolder.imageview2.setVisibility(View.GONE);
itemHolder.videoView.setVisibility(View.GONE);
}

Can't access to a spinner in Java

I've got an activity where there is a button which opens an AlertDialog.
My dialog works and I decided to add a layout to it which contains a spinner.
So I have 3 documents :
mainActivity.java : Its role is to open a Dialog
activity_main.xml
dialog_main.xml : The dialog's layout containing the spinner
I try to retrieve in mainActivity.java the spinner declared in dialog_main.xml (in order to add it an adapter) :
Spinner mySpinner = (Spinner)findViewById(R.id.mySpinner);
However mySpinner = NULL, I can't find mySpinner. What is the problem ?

findViewById
as a method of the Activity class finds Views in your Activity's layout. When you are showing a Dialog, it is not part of your layout, so you have to findViewById in the Dialog's layout.
You are probably inflating a View for the Dialog that you show, you cou can use this view to find your Spinnner.
It probably looks like
View view = layoutInflater.inflate (...);
then you do
view.findViewById(...);
Post the code of how how show the Dialog and I'll show you if you can't do it.

How to know the status of the pages in a ViewPager

I'm implementing a image gallery with a ViewPager.
Each page load a image from Internet and put it in a ImageView.
The gallery also have a share button (external to the ViewPager).
I want to disable the button when the image is loading and re-enable it when the image is visible.
How can I know the status of the current page (if the image is beeing displayed or not) from the Activity containing the ViewPager?
Thanks

You can override setPrimaryItem function
public void setPrimaryItem(android.view.ViewGroup container,
int position, Object object) {
super.setPrimaryItem(container, position, object);
//check if image is loaded here
};

Dialog context issue - Android

I have created a dialog box like so using a custom layout:
dialog = new Dialog(FetchMenu.this, R.style.CustomDialogTheme);
dialog.setContentView(R.layout.custom_dialog_iab);
dialog.show();
I am now trying to edit a textbox within 'layout.custom_dialog_iab' for example:
TextView text = (TextView) findViewById(R.id.all_topics_unlock_button);
text.setText("Purchased");
My Question: How do I get the right context to be able to edit the textboxes?
P.S. I have tried 'dialog.getContext()' but still keep throwing null pointers?

You need to use:
TextView text = (TextView) dialog.findViewById(R.id.all_topics_unlock_button);
Note the dialog. in front of findViewById
regular findViewById() will search your activity layout rather than the dialog layout.
