My listview is not showing any chats from parse database

My listview is not showing any chats from parse database - android

I have three classes one user list holds the list of user when each user is clicked it directs you to chat class which holds the chats activity. I also have the conversation list which holds a single conversation. The problem is the list view does not show previous chats stored in parse data base how can I load the previous chats to my list view.

The first, you don't need to set adapter multiple time, only set adapter at the first time in your method initView().
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
lvToday.setHasFixedSize(true);
lvToday.setNestedScrollingEnabled(false);
if(mTrainingDTO == null) {
mTrainingDTO = new ArrayList<>();
}
if(null == mTrainingDTOAdapter ) {
mTrainingDTOAdapter = new RecyclerAdapter(getActivity(), mTrainingDTO, FragmentTapNew.this);
}
lvToday.setAdapter(mTrainingDTOAdapter);
Thread t = new Thread(new Runnable() {
#Override
public void run() {
today();
}
});
t.start();
After that, you don't need to call lvToday.setAdapter(mTrainingDTOAdapter);
many times. Just call mTrainingDTOAdapter.notifyDataSetChanged(); if having any changes in your data mTrainingDTO.

The errorlog - error:No adapter attached; skipping layout indicates that you've attached LayoutManager but you haven't attached an adapter yet, so recyclerview will skip layout. I'm not sure but, in other words recyclerView will skip layout measuring at the moment.
to prevent this errorLog Try to set an adapter with an empty dataSet i.e. ArrayList or
Attach LayoutManager just before you are setting your adapter.

Try this,
private void initViews() {
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager(getActivity());
lvToday.setLayoutManager(mLinearLayoutManager);
lvToday.setHasFixedSize(true);
lvToday.setNestedScrollingEnabled(false);
Thread t = new Thread(new Runnable() {
#Override
public void run() {
today();
}
});
t.start();
}

cannot add column with 'put' method in Parse database

I'm developing real-time messenger application with Parse and want to display all of users in ListView. So I also want to reference if user is online or offline, I tried 'put' method to add column named "online" and put information about it. When it went wrong, I added that column myself, but it still did not work. Here it's what I tried in UserList class at all:
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import com.parse.FindCallback;
import com.parse.ParseException;
import com.parse.ParseUser;
import java.util.ArrayList;
import java.util.List;
public class UserList extends AppCompatActivity {
public static ArrayList<ParseUser> userList;
public static String TAG = "UserList";
public static ParseUser user = new ParseUser();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_list);
updateUserStatus(true);
}
#Override
protected void onDestroy() {
super.onDestroy();
updateUserStatus(false);
}
#Override
protected void onResume() {
super.onResume();
loadUserList();
}
private void updateUserStatus(boolean isOnline) {
user.put("online", isOnline);
user.saveEventually();
//System.out.println("getBoolean's result : " + user.getBoolean("online"));
}
private void loadUserList() {
ParseUser.getQuery().whereNotEqualTo("username", user.getUsername()).findInBackground(new FindCallback<ParseUser>() {
#Override
public void done(List<ParseUser> objects, ParseException e) {
if (objects != null) {
if (objects.size() == 0) System.out.println("No user found");
userList = new ArrayList<>(objects);
ListView list = (ListView) findViewById(R.id.userList);
list.setAdapter(new UserAdapter(UserList.this));
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
startActivity(new Intent(UserList.this, MainActivity.class));
finish();
}
});
}
else {
System.out.println("exception detected while loading user list");
e.printStackTrace();
}
}
});
}
}
UserAdapter class:
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import com.parse.ParseUser;
public class UserAdapter extends BaseAdapter {
public static String TAG = "UserAdapter";
public TextView labelname;
LayoutInflater layoutInflater;
public UserAdapter(Context context){
layoutInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return UserList.userList.size();
}
#Override
public ParseUser getItem(int index) {
return UserList.userList.get(index);
}
#Override
public long getItemId(int index) {
return index;
}
#Override
public View getView(int pos, View v, ViewGroup group) {
ParseUser c = getItem(pos);
if (v == null) {
v = layoutInflater.inflate(R.layout.chat_item, null);
}
labelname = (TextView) v;
labelname.setText(c.getUsername());
labelname.setCompoundDrawablesWithIntrinsicBounds(c.getBoolean("online") ? R.drawable.ic_online
: R.drawable.ic_offline, 0, R.drawable.arrow, 0);
return v;
}
}
I tried saveInBackground with SaveCallback, but it throws exception named:
Caused by: java.lang.IllegalArgumentException: Cannot save a ParseUser until it has been signed up. Call signUp first
But I'm puzzled more than I was 1 hour ago. I authorize my user in another class and it seems not to be problem.

This was open bug of Parse. might be possible that not solved yet. look at this and this too.
instead of saveEventually() use saveInBackground()
and
you can't do like that
ParseUser user = new ParseUser();
if you want logged user than get like this
ParseUser user = ParseUser.getCurrentUser();
and before getting logged user you must do sign up

Calling activitygroup from customlistadapter

I am working on an android app which is having functionality of tabs.
Everything is working fine but I am not able to call activtygroup from listadapter.
Here is my code for list adapter:
import java.util.ArrayList;

public class AllyListAdapter extends BaseAdapter{
Activity ctx;
ArrayList<Object> alist;
private ImageLoader imageLoader;
AllyBean allyBean;
private String photoPath;
public AllyListAdapter(Activity ctx, ArrayList<Object> alist) {
super();
this.ctx = ctx;
this.alist = alist;
imageLoader=new ImageLoader(ctx);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return alist.size();
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(int position, View arg1, ViewGroup arg2) {
LayoutInflater linf=(LayoutInflater) ctx.getSystemService(ctx.LAYOUT_INFLATER_SERVICE);
View v=linf.inflate(R.layout.ally_list_row, null);
TextView tv=(TextView)v.findViewById(R.id.allyName);
ImageView profileImage=(ImageView)v.findViewById(R.id.ally_image);
Button inviteBtn=(Button)v.findViewById(R.id.invite_btn);
//SHOW DATA FROM LIST
allyBean=(AllyBean)alist.get(position);
tv.setText(allyBean.getName());
photoPath=allyBean.getAvatar();
profileImage.setTag(photoPath);
imageLoader.displayImage(photoPath, ctx, profileImage, false);
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent=new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
});
return v;
}
/*public void replaceContentView(String id, Intent newIntent) {

Make it like this you can access everything by doing like this.
public class AddRemoveFriendScreen extends ActivityGroup implements OnClickListener, IServerResponse

#Override

class AllyListAdapter extends BaseAdapter
{
//Now you can call everything from ActivityGroup
}
}
Hope this will help you.

According to the android developper reference, you may use Fragments.
ActivityGroup is deprecated. Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.
You can try this trick.
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(ctx instanceof ActivityGroup){
Intent intent = new Intent(ctx.getParent(),AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.getParent().startActivity(intent);
}
else{
Intent intent = new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
}
});
If it doesn't work just use internal class for your adapter in your AddRemoveFriendScreen class.
