How to start activity from onClick on RecyclerView in actvity

Hello Everyone I am trying to start activity when I click on RecyclerView , it is started when I add the code in the Custom Adapter , but when I write it in Activity it Just give me the position on Log ..
so any help
here is the code OnClick in activity and that's what I tried to do
#Override
public void onItemClick(int position, View v) {
Log.e("TAG", "You clicked number " + mAdapter.getItemId(position) + ", which is at cell position " + position);
// this.startActivity(new Intent(FrameListActivity.this , FinalActivity.class));
// Bitmap frameSelected = results.get(position).getImage();
// Log.e("frameSelected" , frameSelected+"");
// createImageFromBitmap(frameSelected , "frameImage");
positionId = "" + position;
Context context = v.getContext();
Intent intent = new Intent(context.getApplicationContext() , FinalActivity.class);
intent.putExtra("resultpos", "" + positionId);
context.getApplicationContext().startActivity(intent);
finish();
}
here is the activity

I used setOnClickListener in itemView in the onBindViewHolder.
the itemView is like the container of all things that has the item...
public class MyClassAdapter extends RecyclerView.Adapter<MyClassAdapter.MyClassViewHolder> {
....
....
....
#Override
public void onBindViewHolder(#NonNull final MyClassViewHolder holder, int position) {
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Context context = v.getContext();
Intent intent = new Intent(context , NewActivity.class);
context.startActivity(intent);
}
});
}
....
....
}
This is another example that I find
I created the setOnClickListener on view in onCreateViewHolder
public class MyClassAdapter extends RecyclerView.Adapter<MyClassAdapter.MyClassViewHolder> {
....
....
....
#NonNull
#Override
public MyClassViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
View view = layoutInflater.inflate(R.layout.row_item_example, parent, false);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("Click in oncReateViewHolder");
}
});
return new SolicitudViewHolder(view);
}
....
....
}

Try this:
in your onResume(): you are already attaching setOnItemClickListener into the PhotoRecyclerViewAdapter
#Override
protected void onResume() {
super.onResume();
((PhotoRecyclerViewAdapter) mAdapter).setOnItemClickListener(new PhotoRecyclerViewAdapter
.MyClickListener() {
#Override
public void onItemClick(int position, View v) {
Log.i(LOG_TAG, " Clicked on Item " + position);
Intent intent = new Intent(FrameListActivity.this , FinalActivity.class);
intent.putExtra("resultpos", "" + position);
startActivity(intent);
}
});
}

Use this:
#Override
public void onItemClick(int position, View v) {
Log.e("TAG", "You clicked number " + mAdapter.getItemId(position) + ", which is at cell position " + position);
// this.startActivity(new Intent(FrameListActivity.this , FinalActivity.class));
// Bitmap frameSelected = results.get(position).getImage();
// Log.e("frameSelected" , frameSelected+"");
// createImageFromBitmap(frameSelected , "frameImage");
positionId = "" + position;
Context context = FrameListActivity.this;
Intent intent = new Intent(context , FinalActivity.class);
intent.putExtra("resultpos", "" + positionId);
context.startActivity(intent);
finish();
}
Hope this helps.

As far as I know, the proper way to attach an onClickListener to a recyclerView, is to do so in the onBindViewHolder method as mentioned as the first option in the answer below. This method binds the properties to each of the recyclerview item, therefore the onClickListener could also be attached similarly.

Using searchview in actionbar in fragments

I am displaying a userlist and I am using serachview in my actionbar to search. When I am using the searchView in activity, it works fine but when I use it for fragment, searchview doesn't work. It does not search in the listview.
Below is my code.

I have written setHasOptionsMenu(true); in onCreate of UserFragment.java
The logout functionality works fine but the search isn't working.
I have tried various options given on Stackoverflow as well as from other resource, but nothing worked. :(
Any help is appreciated.
Thanks in advance.

Create Constructor in your fragment. Pass Context object inside fragment constructor.which allows your activity as global access.

Remove this line and it will work

I'm not sure which of these classes I need to be restoring and how I can restore the previous details and images in HomeFragment after clicking back from the detail activity. I would be able to just describe a parent activity in my manifest but the main class holding everything is a fragment and android doesn't let you choose parent fragments! Any ideas or help would be appreciated.

Try to remove initialization of List from declaration.
private List buyersProfiles = new ArrayList();
And make initialization in onCreateView method if List is null.

In the xml that you have posted,replace the TAG <Fragment> with <LinearLayout> or <RelativeLayout> and inside this you simply show what you want to display in you UI
Make sure you extend Fragment class in you fragment activity

Could you post the code for your fragment? The problem could be with your import statements. You have 'import android.support.v4.app.FragmentActivity'. Do you have 'import android.support.v4.app.Fragment' in your fragment file?

Android ListView showing only first 4 items on repeat

I have a Fragment called User Management where I collect data from a server and display it in a ListView. It's also refreshable via SwipeRefreshLayout.
What happens is, if I get data on 1-4 users, it displays the data correctly. However, if I get data on more than 4 users, it displays the first 4 correctly, and instead of the fifth, it's the first one again, instead of the 6th, it's the second one and so on and so on.
I've tried everything I could think of, the adapter is getting the data correctly, the ListView is getting the adapter correctly, but for some reason, it peaks at 4 users displayed, and simply repeats them after that (the funny thing is, if I add a user and then refresh, it simply repeats the next user one more time in the list, so it's definitely aware of the change in user number)
Can you help me finding the problem?

Thank you!

There is a huge problem in your SampleAdapter.getView() method.
When you scroll down the View disappearing at the top of the screen is reused to be injected at the bottom. This reused View is the convertView you get as getView parameter.
As you code is, the reused view is injected with the exact same data (because if (convertView == null) { is always false when you scroll).
Images and texts are not updated.
When you scroll down, the element disappearing at the top just appears at the bottom, and so does others...
You should be doing something like:
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_usermana, null);
// The ViewHolder constructor should handle the mapping of its views
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// Here you should only use holder as in:
holder.userpicture.setImageDrawable(getResources().getDrawable(getItem(position).userPicture));
...
}

This method looks strange, and is perhaps suspect. I don't see getUsers_mana() defined anywhere in this sample code, so I don't know if it is the problem or not. For one, you should call that 'UserManager.getInstance().getUsers_mana()' and then 'get(i)' once each and store the results in variables.
private void setContent(){
SampleAdapter adapter = new SampleAdapter(getActivity());
adapter.notifyDataSetChanged();
try {
if (!UserManager.getInstance().getUsers_mana().isEmpty()) {
for (int i = 0; i < UserManager.getInstance().getUsers_mana().size(); i++) {
Log.e("adding to adapter:",UserManager.getInstance().getUsers_mana().get(i).firstName + " " + UserManager.getInstance().getUsers_mana().get(i).lastName + "" + UserManager.getInstance().getUsers_mana().get(i).id + "" + UserManager.getInstance().getUsers_mana().get(i).username + "group:" + UserManager.getInstance().getUsers_mana().get(i).group);
adapter.add(new SampleItem(
UserManager.getInstance().getUsers_mana().get(i).id
, UserManager.getInstance().getUsers_mana().get(i).firstName + " " + UserManager.getInstance().getUsers_mana().get(i).lastName
, UserManager.getInstance().getUsers_mana().get(i).username
, UserManager.getInstance().getUsers_mana().get(i).group
, R.drawable.users_test
, R.drawable.settings
, R.drawable.delete
, UserManager.getInstance().getUsers_mana().get(i).activated
));
}
listView.setAdapter(adapter);Log.e("setting","ListView");
}
}catch (Exception e){
Log.e("error setContent", e.getMessage().toString());
}
}

It is because you are not doing anything in the
else {
convertView.getTag();
}
Check here
Why we should re-assign values for a recycled convertView in getView()
You have to reassign values to the convertView with the data of the 5th roq, 6th row etc. otherwise it still contains the old data

Remove the initialization of holder on the top and just put this line of code in the beginning of getView function.
ViewHolder holder = null;
You need to re initialize holder if its null and you need to update it with latest data if its not null.

See this sample it might help you
