Call an dialog fragment method from Activity to Dialog Fragment

I am showing one dialog fragment (showing progress ) in my activity . Calling rest api methods are in my activity . Based on rest api results , I need to some progress in the dialog fragment . So I need to call a method of dialog fragment from activity . I tried with event bus , (Firing from Activity caught on Dialog Fragment ) - But events are not caught in dialog fragment . Is there any other solution ?

Two Recycler views inside nested scroll view

I have a Nested Scroll view and inside this, I have a Linear Layout that includes two recycler views. Now the problem is that the first recycler view is not expanding up to its full extent. i.e. there are 5 items in the first recycler view list but it is only showing the first item if I put wrap content. This should expand up to 5 items because of wrap content but it is not working. If I fixed the height to 200DP or 300dp then it started to show more items up to that height. However, I want to show all the items of the first recycler view and then when I scroll it should start second recycler view items after the first recycler view items end.
My layout is:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView

Please Help. Where I did something wrong. I tried so many ways from internet but nothing is working. Here is a screenshot of the this screen
The LABEL latest bookings has 5 items but it is only showing one and not expanding up to 5 items. However the second LABEL Past bookings is working perfectly and showing all items when i scroll up to end.

Set the first RecyclerView’s height to wrap_content and set setNestedScrollingEnabled to false
RecyclerView rv_ongoing_bookings= (RecyclerView) findViewById(R.id.rv_ongoing_bookings);
rv_ongoing_bookings.setNestedScrollingEnabled(false);

To achieve it my approach would be to customize my recyclerView adapter to act as a section header recycler view, something like this:
https://android-arsenal.com/details/1/4495

The following code will make recycler view expandable...
public class ExpandableRecyclerView extends RecyclerView
{
private boolean expanded = false;
public ExpandableRecyclerView(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
}
public ExpandableRecyclerView(Context context)
{
super(context);
}
public ExpandableRecyclerView(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public boolean isExpanded()
{
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
if (isExpanded())
{
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
else
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded)
{
this.expanded = expanded;
}
}
Usage... use it the way you use recycler view...
just set recyclerView.setExpanded(true);
You may directly use it inside scrollview...

So, it's not really an answer to your question, it's more like a suggestion to use RecyclerView as it should be depending on the screenshot which you included in your question.
You really don't need to create two RecyclerView's to achieve the layout which you need. As I understand you want to show some items and put a separator with text depending on something (Booking's date as I can see).
In RecyclerView.Adapter you have getItemViewType where you can return an int value depending on some variables.For example your getItemViewType should look something like this:
#Override
public int getItemViewType(int position) {
MyObject myObject = mItems.get(position);
// myObject.isSeparator() is a sample function which helps you identify it you should show construct a booking view or separator
if(myObject.isSeparator()){
// this variable is declared inside your Adapter ->
// private static final int VIEW_TYPE_SEPARATOR = 1;
return VIEW_TYPE_SEPARATOR;
}
// private static final int VIEW_TYPE_BOOKING = 0;
return VIEW_TYPE_BOOKING;
}
Depending on those values you need to create two ViewHolder's :
#Override
public RecyclerView.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
if (VIEW_TYPE_SEPARATOR == viewType) {
new SeparatorViewHolder(/* Some params which you need here */);
}
return new BookingViewHolder(/* Some other params which you need here */);
}
And ->
#Override
public void onBindViewHolder(#NonNull RecyclerView.ViewHolder holder, int position) {
if (VIEW_TYPE_SEPARATOR == getItemViewType(position)) {
// Populate SeparatorViewHolder
} else {
// Populate BookingViewHolder
}
}
And at the end you should populate your List with the objects you need to determine if the item is a Booking item for example or a Separator.
I hope you got the main idea.

dm77 barcodescanner Zbar camera Preview delay in fragment

how to read content description for an alert dialog in android
