Custom Adapter not Changing Layout According to Condition

I am working on a chat app and I am very new to using ListViews and ArrayAdapters, as well as Custom Adapters. I am having a problem that causes all my items in my list to be of one layout, even they are supposed to change according to a booleans(true would be an outgoing chat bubble, and false would be an incoming chat bubble).
Here is my code for the retreival of the chat(It isn't the whole file, just a snippet):
Variable declarations:
final ArrayList<chatBubble> objects = new ArrayList<>();
final CustomAdapter customAdapter = new CustomAdapter(this, objects);
listView.setAdapter(customAdapter);
Code to get messages and add to list:
mDatabase.child("chat").child("publicDump").child("dumpedMessages").child("message" + i).addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
final String message = dataSnapshot.getValue(String.class);
if (message != null) {
final String extract = message.substring(message.lastIndexOf("<") + 1, message.indexOf(">"));
mDatabase.child("users").child("c").child("emailToUsername").child(mAuth.getCurrentUser().getEmail().replace(".", ",")).child("username").addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
String username = dataSnapshot.getValue(String.class);
if (username != null) {
if (username.equals(extract)) {
Log.i("Extract", extract);
int semicnt = 0;
int num = 0;
//Log.i("Loop", "Yes");
for (int i = 0; i < message.length(); i++) {
//Log.i("Loop", "y");
if (String.valueOf(message.charAt(i)).equals(":")) {
semicnt++;
//Log.i("cnt", String.valueOf(semicnt));
if (semicnt == 3) {
num = i;
i = message.length() - 1;
String time = message.substring(0, (Math.min(message.length(), num)));
String finalM = message.replace(time + ": ", "").replace("<" + extract + "> ", "");
chatBubble chat = new chatBubble(finalM, "From: " + extract + " At: " + time, true);
objects.add(chat);
}
}
}
} else {
int semicnt = 0;
int num = 0;
// Log.i("Loop", "Yes");
for (int i = 0; i < message.length(); i++) {
//Log.i("Loop", "y");
if (String.valueOf(message.charAt(i)).equals(":")) {
semicnt++;
//Log.i("cnt", String.valueOf(semicnt));
if (semicnt == 3) {
num = i;
i = message.length() - 1;
String time = message.substring(0, (Math.min(message.length(), num)));
String finalM = message.replace(time + ": ", "").replace("<" + extract + "> ", "");
chatBubble chat = new chatBubble(finalM, "From: " + extract + " At: " + time, false);
objects.add(chat);
}
}
}
}
customAdapter.notifyDataSetChanged();
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
Here is my code for my chatBubble:
package com.tejasmehta.codeychat;
public class chatBubble {
private String msg;
private String date;
private boolean myMessage;
public chatBubble(String msg, String date, boolean myMessage) {
this.msg = msg;
this.date = date;
this.myMessage = myMessage;
}
public String Msg() {
return msg;
}
public String Date() {
return date;
}
public boolean myMessage() {
return myMessage;
}
}
And here is my code for my customAdapter(which shows that if the boolean, myMessage, is true, it will load a different layout, and a different one for false):
public class CustomAdapter extends BaseAdapter {
private LayoutInflater inflater;
private ArrayList<chatBubble> objects;
private class ViewHolder {
TextView msg;
TextView date;
}
public CustomAdapter(Context context, ArrayList<chatBubble> objects) {
inflater = LayoutInflater.from(context);
this.objects = objects;
}
public int getCount() {
return objects.size();
}
public chatBubble getItem(int position) {
return objects.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int layoutResource; // determined by view type
chatBubble ChatBubble = getItem(position);
if (ChatBubble.myMessage()) {
layoutResource = R.layout.right_bubble;
} else {
layoutResource = R.layout.left_bubble;
}
if(convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(layoutResource, null);
holder.msg = convertView.findViewById(R.id.txt_msg);
holder.date = convertView.findViewById(R.id.date);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.msg.setText(objects.get(position).Msg());
holder.date.setText(objects.get(position).Date());
return convertView;
}
}
Thank You for all of your help!

the problem is your getview
The view is being recycled so convertview already has a layout. so its not being reinflated to the correct layout.
you need to use getViewType() and getViewTypeCount() to tell the listview you want to use different layouts
http://android.amberfog.com/?p=296
#Override
public int getViewTypeCount() {
return 2;
}
#Override
public int getItemViewType(int position) {
return getItem(position).myMessage()?0:1;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int layoutResource; // determined by view type
chatBubble ChatBubble = getItem(position);
if (ChatBubble.myMessage()) {
layoutResource = R.layout.right_bubble;
} else {
layoutResource = R.layout.left_bubble;
}
if(convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(layoutResource, null);
holder.msg = convertView.findViewById(R.id.txt_msg);
holder.date = convertView.findViewById(R.id.date);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.msg.setText(objects.get(position).Msg());
holder.date.setText(objects.get(position).Date());
return convertView;
}

How to disable previous items in a ListView

I am trying to develop an activity where there is a custom listView made out of CustomAdapter.
The list consists of a TextView and an EditText. The EditText when clicked, it auto fetches the system time.
What I want is when a particular EditText is filled, I want all the previous(above) list items in the sequence to be disabled.
So far, I have tried using isEnabled() and areAllItemsEnabled() functions returning respective boolean values using position, but however didn’t work.
Please help me achieve the above.
Thanks.
This is my CustomAdapter Class

You can do this as below mentioned -:
You need to store the position of clicked button was. So initialize a variable in your class
int mButtonSelected = -1;
EDIT 1.
Then make a change to your isEnabled method
#Override
public boolean isEnabled(int position) {
if(position<mButtonSelected){
return false;
}
return true;
}
That will work it if any other button was clicked. but you have to do that in your onClick
mButtonSelected = position;
notifyDataSetChanged();
Let me it worked or not
EDIT
see below changes in your code-:
public class SelectStnListByRoute extends BaseAdapter {

Get the position of the row which is clicked and then set onclick false for positions less than clicked position
as follows:
viewHolder.txtStnArr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.e("Position: " , String.valueOf(position));
for (int i = 0; i < position; i++) {
viewHolder.txtStnArr.setEnable(false);
}
notifyDataSetChanged();
}
});

AdapterView of Gridview is not refreshing, it is showing weird response (Some times it is refreshing some times not)

I am setting the adapter of gridview on a fragment. this fragment is attached on the layout of view pager and viewpager is attached in an activity.
I have checked my arraylist data is refreshed but view is not refreshing.
My code is:
Setting the adapter in the onCreate of Activity::
for(ArrayList<Item> newLst : updateList){
newPropertySubList.add(newLst);
}
Log.e("newPropertySubList","newPropertySubList"+newPropertySubList.size());
adapter = new PropertyPagerAdapetr(getSupportFragmentManager());
//propertyViewPager.setAdapter(adapter);
adapter.notifyChangeInPosition(1);
propertyViewPager.setAdapter(adapter);
adapter.notifyDataSetChanged();
mIndicator.setViewPager(propertyViewPager);
PropertyPagerAdapetr is: in this code section GridviewFragment new instance is created when adapter is setting.
public class PropertyPagerAdapetr extends FragmentPagerAdapter {
private long baseId = 0;
public PropertyPagerAdapetr(FragmentManager fm) {
super(fm);
}
#Override

Could be you're mixing GridLayout and GridView. They are different entities.
In setUpGridLayout() you are inflating a grid_view_imageviewitem and adding it to a GridLayout, not GridView.

i have solve the issue using

};
Runnable disconnectCallback = new Runnable() {
#Override

I don't know what's causing the problem. I can use the same method on my fragments but in this adapter it's not working.

Change
adapter = new AdapterPOI(getApplicationContext(), ....)
to
adapter = new AdapterPOI(this, ....)
in the code where you call the adapter's constructor. You get the error because getApplicationContext() cannot be casted to an ActivityCategorySelected. That's an Application context; whereas the adapter is expecting an Activity's context.

Memory leak when drag PullToRefresh ListView

The problem is that when i stretch up the pullToRefreshLiew (similar to listview), the memory the application occupy will be increasing step by step. I have tried many methods from the internet, but the bug still exists.
