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
public class SelectStnListByRoute extends BaseAdapter implements View.OnClickListener {
Context context;
ArrayList<StnNames> stnList;
LayoutInflater layoutInflater = null;
ViewHolder viewHolder;
private int mLastClicked;
public SelectStnListByRoute(Context context, ArrayList<StnNames> stnList) {
super();
this.context = context;
this.stnList = stnList;
layoutInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return stnList.size();
}
#Override
public Object getItem(int position) {
return stnList.get(position);
}
#Override
public long getItemId(int position) {
return stnList.indexOf(getItem(position));
}
public int getViewTypeCount() {
return 1;
}
#Override
public boolean areAllItemsEnabled() {
return false;
}
#Override
public boolean isEnabled(int position) {
if(position==position){
return false;
}
return false;
}
#Override
public View getView(final int position, View convertView, ViewGroup viewGroup) {
int type = getItemViewType(position);
StnNames stnDetails = stnList.get(position);
viewHolder = new ViewHolder();
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.footplate_custome_layout, null);
viewHolder.txtStnNAme = (TextView) convertView.findViewById(R.id.txtStnCode);
viewHolder.txtStnArr = (TextView) convertView.findViewById(R.id.txtArrivalTime);
viewHolder.txtStnDep = (TextView) convertView.findViewById(R.id.txtDepTime);

}
viewHolder.txtStnNAme.setText(stnDetails.getStnCode());
viewHolder.txtStnArr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.e("Position: " , String.valueOf(position)); //Here I am getting the position of the row item clicked, where should I put the Onclick false for disabling all of the above fields using the position?
}
});
viewHolder.txtStnDep.setOnClickListener(this);
viewHolder.txtStnArr = (TextView) convertView.findViewById(R.id.txtArrivalTime);
if (stnDetails.getArrivalTime() != null) {
viewHolder.txtStnArr.setText(stnDetails.getArrivalTime());
} else {

}
if (stnDetails.getDeptTime() != null) {

}
return convertView;
}
class ViewHolder {

}
#Override

switch (id) {
case txtArrivalTime:

textViewArrVal.setClickable(false);
StnNames listItemsArrr = (StnNames) textViewArrVal.getTag();

}

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();
}
});

Adapter-Showing view only when there is a change in a value

Below is my complete adapter class of sendbird chatting.Currently date with time is displayed with every message.viewHolder.getView("left_time") and viewHolder.getView("right_time") are views for displaying date with time and it is calculated in method getDisplayDateTime.I want date with time to be displayed only when there is a change in date.For example if there is set of messages dated 23rd june then date with time should be displayed only for the first message with date 23rd june.
I tried doing that by detecting whenever there is a change in date by storing date in xyz variable and comparing it with date of every message and whenever they are unequal then making date view of that message visible and assigning the new date to xyz variable for comparison with future messages.But this approach fails when i scroll down and scroll up list.
What is the ideal approach for achieving this?

return DateFormat.getTimeFormat(context).format(date);
}
return DateFormat.getDateFormat(context).format(date) + " " + DateFormat.getTimeFormat(context).format(date);
}

Try below code for your method,
private static String getDisplayDateTime(Context context, long milli, long milli2)
{
Date date = new Date(milli);
Date previousDate = new Date(milli2);
String strCurrentDate = "", strPreviousDate = "";
if (System.currentTimeMillis() - milli < 60 * 60 * 24 * 1000l)
{
strCurrentDate = DateFormat.getTimeFormat(context).format(date);
if(milli2 != -1)
strPreviousDate = DateFormat.getTimeFormat(context).format(previousDate);
//return strCurrentDate.equals(strPreviousDate) ? "" : strCurrentDate;
}
else
{
strCurrentDate = DateFormat.getDateFormat(context).format(date) + " " + DateFormat.getTimeFormat(context).format(date);
if(milli2 != -1)
strPreviousDate = DateFormat.getDateFormat(context).format(strPreviousDate) + " " + DateFormat.getTimeFormat(context).format(strPreviousDate);
}
return strCurrentDate.equals(strPreviousDate) ? "" : strCurrentDate;
}
Now call your methods like below
if(position > 0)
{
final Object previousItem = getItem(position - 1);
Message previousMessage = (Message) previousItem;
viewHolder.getView("right_time", TextView.class).setText(getDisplayDateTime(mContext, message.getTimestamp(), previousMessage.getTimestamp()));
}
else
{
viewHolder.getView("right_time", TextView.class).setText(getDisplayDateTime(mContext, message.getTimestamp(), -1));
}

I had a similar problem (ref this SO Question) few months ago and nothing worked except extending from ArrayAdapter<MyObject> instead of BaseAdapter.
So, change the base class of your adapter to ArrayAdapter<MyObject> and implement the prompted method of the abstract class. you might need to move some you your existing code to these overridden methods for better performance.

You can force the system to redraw all items by calling BaseAdapter.notifyDataSetChanged()

Custom Adapter not populating GridView

I have made a custom adapter to populate my gridView. What I am doing is that i am trying to populate the gridview with two different data(that too are custom) which are: Movies and FavouriteMovies. when the dridview is updated using Movies it updates just fine but when it FavouriteMovies it does not. I am storing FavouriteMovies in a sqlite db and then querying it to return a cursor.the data returns perfectly and there is no error. the main problem is with my MoviesAdapter. inside this when i add Movies to adapter it adds to the list inside MoviesAdapter and it works perfectly but when I add FavouriteMovies to the adapter it does not add it inside the favouriteList inside MoviesAdapter and its size is always zero.
please help!!
here is my MoviesAdapter:
package com.akshitjain.popularmovies;
import android.content.Context;
import android.graphics.BitmapFactory;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import com.squareup.picasso.Picasso;
import java.util.ArrayList;
import java.util.List;
public class MoviesAdapter extends BaseAdapter {
private Context mContext;
List<Movies> list = new ArrayList<>();
List<FavouriteMovies> favouriteList = new ArrayList<>();
public MoviesAdapter(Context c) {
this.mContext = c;
}
#Override
public int getCount() {
if (list != null)
return list.size();
else
return favouriteList.size();
}
#Override
public Object getItem(int position) {
if (list != null)
return list.get(position);
else
return favouriteList.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(mContext).inflate(R.layout.grid_item_movies, parent, false);
}
ImageView moviePoster = (ImageView) convertView.findViewById(R.id.grid_item_movie_image);
if (list != null) {
Movies movies = list.get(position);
String posterPath = movies.posterPath;
final String POSTER_FINAL_URL = Constants.IMAGE_BASE_URL + Constants.POSTER_SIZE_LARGE + posterPath;
Picasso.with(mContext).load(POSTER_FINAL_URL.trim()).into(moviePoster);
} else {
FavouriteMovies favouriteMovies = favouriteList.get(position);
byte[] bb = favouriteMovies.posterImage;
moviePoster.setImageBitmap(BitmapFactory.decodeByteArray(bb, 0, bb.length));
}
return convertView;
}
public void add(Movies movies) {
list.add(movies);
}
public void offlineAdd(FavouriteMovies favouriteMovies) {
favouriteList.add(favouriteMovies);
}
public void clear() {
list.clear();
}
}
and here is where I am adding to the adapter:
#Override
protected void onPostExecute(Movies[] strings) {
if (strings != null) {
mMoviesAdapter.clear();
for (Movies moviesStr : strings) {
mMoviesAdapter.add(moviesStr);
}
}else if(mFavouriteMovies != null){
mMoviesAdapter.clear();
for(FavouriteMovies favouriteMoviesStr : mFavouriteMovies){
mMoviesAdapter.offlineAdd(favouriteMoviesStr);
}
}
Log.v("FetchMoviesTask","Count :" + mMoviesAdapter.getItem(0));
mMoviesAdapter.notifyDataSetChanged();
}
So sorry for my crude language.

You will always have count == 0 if you set your favorite movies.
List<Movies> list = new ArrayList<>();
#Override
public int getCount() {
if (list != null)
return list.size();
else
return favouriteList.size();
}
This will always return a count of 0 since list never is null. You favorite movies get ignored.
Solutions
Since you are only displaying either movies or favorites you should use 2 adapters. If you don't want to do this,
Use a boolean. Just set showFavorites to true, and display those. Or if you keep your null checks,
set the List<Movie> = null; when displaying favorited, then it will also work.

use following adapter:-
boolean[] CheckedItem_Adap;
ImageLoader imgload;
int headercount = 0, childCount;
LinkedList<HashMap<String, String>> allData;
LinkedList<HashMap<String, String>> temp_Header;
LinkedList<HashMap<String, String>> temp_child = new LinkedList<HashMap<String, String>>();

ListView with different layouts with two different objects

I want to populate a ListView with different layouts for odd and even rows. It should look like this:
I use two objects "OddListItem" and "EvenListItem" to store/access the data. I do not know how to pass both objects to my custom listview adapter and get the correct view.
My object classes:
public class OddListItem {
private String time_start;
private String time_end;
private String location;
public OddListItem(String time_start, String time_end, String location) {
super();
this.time_start = time_start;
this.time_end = time_end;
this.location = location;
}
// getters and setters
void setTimeStart(String time_start) {
this.time_start = time_start;
}
void setTimeEnd(String time_end) {
this.time_end = time_end;
}
void setLocation(String location) {
this.location = location;
}
public String getTimeStart() {
return time_start;
}
public String getTimeEnd() {
return time_end;
}
public String getLocation() {
return location;
}
}
public class EvenListItem {
private String image;
private String location;
public EvenListItem (String image, String location) {
super();
this.image = image;
this.location = location;
}
// getters and setters
void setImage(String image) {
this.image = image;
}
void setLocation(String location) {
this.location = location;
}
public String getImage() {
return image;
}
public String getLocation() {
return location;
}
}

// Tag for Logging

Here I generate the data and call the adapter:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detailed_connection);
generateData();
//fill ListView with custom content from MyCustomAdapter class
mAdapter = new MyCustomAdapter(getApplicationContext());

mAdapter.addItem(odd_items.get(i));
if (i % 1 == 0) {
mAdapter.addSeparatorItem(odd_items.get(i));
}
}
setListAdapter(mAdapter);
//set duration text
tv_duration = (TextView)findViewById(R.id.tv_duration);
tv_duration.setText("Dauer: 22 Minuten");
}
private void generateData() {
odd_items = new ArrayList<OddListItem>();
odd_items.add(new OddListItem("12:34", "", "Aktueller Standort"));
odd_items.add(new OddListItem("12:37", "12:37", "TUM"));
odd_items.add(new OddListItem("12:42", "12:42", "Hauptbahnhof Nord"));
odd_items.add(new OddListItem("12:48", "12:48", "Hauptbahnhof"));
even_items = new ArrayList<EvenListItem>();
even_items.add(new EvenListItem("R.drawable.rollator", "3 Minuten Fußweg"));
even_items.add(new EvenListItem("R.drawable.bus", "Richtung Hauptbahnhof Nord"));
even_items.add(new EvenListItem("R.drawable.rollator", "6 Minuten Fußweg"));
mData = new Data(odd_items, even_items);
}
Any help would be great. Maybe there is also a better approach then please let me know.

I would create a Single list of Items
public class Items {
private String time_start;
private String time_end;
private String location;
private int image;
private String locationeven;
private int oddoreven;
public String getTime_start() {
return time_start;
}
public void setTime_start(String time_start) {
this.time_start = time_start;
}
public String getTime_end() {
return time_end;
}
public void setTime_end(String time_end) {
this.time_end = time_end;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public int getImage() {
return image;
}
public void setImage(int image) {
this.image = image;
}
public String getLocationeven() {
return locationeven;
}
public void setLocationeven(String locationeven) {
this.locationeven = locationeven;
}
public int getOddoreven() {
return oddoreven;
}
public void setOddoreven(int oddoreven) {
this.oddoreven = oddoreven;
}
}
In onCreate of Activity call
generateData() ;
Then
ArrayList<Items> oddorevenlist = new ArrayList<Items>();
private void generateData() {
Items item1 = new Items();
item1.setTime_start("12:34");
item1.setTime_end("");
item1.setLocation("Aktueller Standort");
item1.setOddoreven(0);
oddorevenlist.add(item1);
Items item2 = new Items();
item2.setImage(R.drawable.ic_launcher);
item2.setLocationeven("3 Minuten Fußweg");
item2.setOddoreven(1);
oddorevenlist.add(item2);
Items item3 = new Items();
item3.setTime_start("12:37");
item3.setTime_end("12:37");
item3.setLocation("Tum");
item3.setOddoreven(0);
oddorevenlist.add(item3);
Items item4 = new Items();
