I am simply trying to show a fragments recyclerView inside it's parent activity. The data is there but nothing is showing up. Any thoughts? Here is PagerAdapter, parent and fragment classes with xmls so that all the parts are available to see. I want the RV to fit right here between the CardView and comment line. Thanks for any help!

Thanks again!
While your RelativeLayout(the one just before the ListView) have match_parent as height, it will take the remaining space of the window... so there is no place for your ListView to be shown.
Try this..
Give id to the above Relative layout and use the same below.
<ListView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="vertical"
android:layout_below="#id/"
android:id="#+id/list_cart_view">
</ListView>

USER_IMG.length(); returns the length of the String (the number of chars of "product_images"). You should return the size of the data set instead. Change
#Override
public int getCount() {
return USER_IMG.length();
}
to
#Override
public int getCount() {
if (userImgArrayList == null) {
return 0;
}
return userImgArrayList.size();
}
change your getcount() method to
#Override
public int getCount() {
int count =0
if (userImgArrayList != null) {
count=userImgArrayList.size();
}
return count;
}
And also add notifyDataSetChanged after filling the arraylist like this..
for(int i=0;i< picarray.length();i++)
{
user_img = picarray.getString(i);

It's not possible to make a scrollable view inside a scrollable view. But as a work around this, and only in case that this listviews doesn't take much memory if all views are loaded.
you can use this
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;
public class NonScrollableListView extends ListView {
public NonScrollableListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Do not use the highest two bits of Integer.MAX_VALUE because they are
// reserved for the MeasureSpec mode
int heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightSpec);
getLayoutParams().height = getMeasuredHeight();
}
}
Again, it's not good to use this workaround
you will use this non Scrollable listview in the child.xml layout by adding it as a customized UI component
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.youpackage.uiutils.NonScrollableListView
android:id="#+id/non_scrollable_listview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
You can ExpandableListView in place of making custom view also for data handling you can use ExpandableListAdapter.
