this is my question yearwise activity(from this I launched the fragment activity)

super.onCreate(savedInstanceState);
setContentView(R.layout.question_yearwise);
Button btn2018ii = (Button)findViewById(R.id.btn2018ii);

startActivity(Quiz2018ii);

Replace the method like this,
mainView.findViewById(R.id.check_results).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});

My guess is that at the AdapterView.OnItemClickListener you are using rootView to access the cell properties. Like:
EditText notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
...
CheckBox checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
You should use the parameter View view from onItemClick like that:
EditText notes = (EditText) view.findViewById(R.id.participant_list_item_notes);
...
CheckBox checkBox = (CheckBox) view.findViewById(R.id.participant_list_item_checkbox);
Let me know if it solves your problem.
Edit:
If the problem is having the item clicked, check https://stackoverflow.com/a/20755698/2174489

array adapter returns null

i have two adapters and a fragment, and i want to display feeds on two views, one bottom and one recycler view. Although the Json was working with a list adapter. its not working with the recycler view.
here is the main fragment

Change,

to
pager = (ExpandablePager) view.findViewById(R.id.bottom_feed_container);
Also change,

to
final RecyclerView mRecyclerView = (RecyclerView) view.findViewById(R.id.feeds_list_recycler_view);

Recycler view onBindViewHolder is repeating a weird pattern

I am working on a messaging app which has swipe option to mute or lock conversations, when we press the mute or lock button, small icons are displayed on Recycler view item, but when I try to mute or even lock a certain message it shows the icons on that item but the icons also appears on elements after every 10 counts.
For Example, If I lock the message at position 1, element at position 12 also shows the same icons, if I removed the icon from the first position, icons from the later position is also removed. Any help would be highly appreciated as I am new to android development and still trying to learn.

Viewpager not delete current page position

I am using ViewPager in side activity and add Fragment-State-Pager-Adapter and trying to remove current page position after add the some pages.but every time removed last page position.so please recommend me for use right approach for doing this.Thanks in advance.
This is my activity and adapter code.
public class Main-Activity extends Fragment-Activity implements AddItemFragment.OnFragmentInteractionListener {
PagerAdapter mAdapter;
ViewPager mPager;
Button button ,btn_add;
int pos,TOTAL_PAGES=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_pager);
//THIS IS THE MODEL CLASS WHERE I ADD THE PAGES.
MoveItems.items = new ArrayList<>();
MoveItems.items.clear();
Intialize();
}
public void Intialize() {
mPager = (ViewPager)findViewById(R.id.pager);
mAdapter = new PagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mAdapter);
mPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
pos = position + 1;
}
#Override
public void onPageScrollStateChanged(int state) {
//Function.toast(MainActivity.this, "onPageScrollStateChanged");
}
});
Addpage();
button = (Button)findViewById(R.id.delete_current);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mAdapter.deletePage(mPager.getCurrentItem());
Function.toast(MainActivity.this,"'Delete page");
}
});

}
});
}

ItemDescription item = new ItemDescription();
MoveItems.items.add(item);
if (mAdapter != null)
mAdapter.notifyDataSetChanged();
mPager.setCurrentItem((TOTAL_PAGES - 1));
}
