How do I access/alter views within a listview item from a different item in the same listview?

I have a small app that uses a ListView, each item having a play button, an open/close button, and an ImageView whose visibilty is set to View.GONE. When I press the open/close button, it should set the ImageView in that one list item to View.VISIBLE, change the open/close button, and close any other list items that are displaying the ImageView as VISIBLE and change their open/close button to reflect closed. This is my onClick in my custom ArrayAdapter.
boolean open = false;
imgOpen_Close.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!open){
openClose.setImageResource(R.drawable.open_arrow);
mainImage.setVisibility(View.VISIBLE);
open = true;
}else{
openClose.setImageResource(R.drawable.close_arrow);
mainImage.setVisibility(View.VISIBLE);
open = false;
}
});
How do I access a View in one list item from another list item?

You will need to maintain a separate list of bookname. Let's call it filteredBookname. Initially set it as bookname.
public class BookRecyclerAdopter extends RecyclerView.Adapter<BookRecyclerAdopter.Booksholder>{
private List<String> bookname;
private List<String> filteredBookname;
Context context;
public BookRecyclerAdopter(Context context,List<String> bookname) {
this.bookname = bookname;
this.filteredBookname = bookname
this.context=context;
}
...
// other pieces of code.
and instead of using bookname to populate RecyclerView items, use filteredBookname
and your update list method will be,
public void updatelist(List<String>newlist){
filteredBookname=new ArrayList<>();
filteredBookname.addAll(newlist);
notifyDataSetChanged();
}
Using the above approach, you can always find the proper position of your item in the original list bookname

The reason is that you are picking the wrong list, pick your data from filtered adapter list/model.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Books booksdata= (Books)adapterName.bookname.get(position);
Toast.makeText(MainActivity.this, ""+booksdata.bookname, Toast.LENGTH_SHORT).show();
Intent intent=new Intent(MainActivity.this,Chapters.class);
intent.putExtra("booknumber",booksdata.booknumber);
intent.putExtra("bookname",booksdata.bookname);
startActivity(intent);
}
});
}

holder.cardView_title.setOnClickListener {
when (holder.tv_number.text) {
"1" -> {
(context as Activity).startActivity(Intent(context, Ma1::class.java))
}
"2" -> {
(context as Activity).startActivity(Intent(context, Ma2::class.java))
}
"3" -> {
(context as Activity).startActivity(Intent(context, Ma3::class.java))
}
}
}

Reload Data on Spinner itemSelected

I guess i'm implementing the spinner onItemSelected inappropriately.
So i have spinner values loaded from my database. I'm trying to load data according to the spinner selected but the spinner doesn't persist and the id doesn't pass to the activity. It loads a default id of 1 instead of the selected spinner id. So i'm not sure if the spinner id is being passed. How do i check these and correct them?

Here is the problem (On Spinner Item selection)
Intent intent = getIntent();
startActivity(intent);
Toast.makeText(getApplicationContext(), mySpinner.getItemAtPosition(mySpinner.getSelectedItemPosition()).toString() + " Showing", Toast.LENGTH_SHORT).show();
finish();
**You are starting current activity as new and finish current activity, it means when you select any of items from spinner it will start a new activity and your on create executed again and again, so please place other logic or you can send your values in your activity using intent.putextra() and check in oncreate for null and if values is not null you can set spinner.setSelected(Your Position). For Fragment You can use
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.detach(ComingSoonFragment.this).attach(ComingSoonFragment.this).commit();
for refresh your fragment and pass your data with bundle and check for null if your bundle is null then use your code for defalt and if not null then set your data according to your id.
**
Thanks

In your spinner inside OnItemSelectedListener use parent.getItemAtPosition(position) to get the correct value
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(position).toString(),
Toast.LENGTH_SHORT).show();
//Do your staff here
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Passing String array to another Activity with Custom View

I'm having an issue passing an array into a listview
I can pass an image to the second activty but when I
try to pass an array to the listview I get a lang.NullPointerException error
and the app crashes.
any helpful input would be great Thanks
here is the code
Main Activity
package com.example.androidlistview;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
public class MainActivity extends Activity {
ListView listView;
// Defined the text values to show in ListView
String[] values = new String[]{"Barack Obama","Donald Trump","Bill Clinton",
"Hillary Clinton","Joe Biden"};
// Defined the image ids to show in ListView
Integer[] images = {
R.drawable.image1,R.drawable.image2,R.drawable.image3,R.drawable.image4,
R.drawable.image5
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// create the custom view
CustomView adapter = new CustomView(MainActivity.this, values, images);
// Get ListView object from xml
listView = (ListView) findViewById(R.id.container);
//set adapter
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
if(position == 0){
Intent contact = new Intent(MainActivity.this, Details.class);
String[] details= new String[]{"Barack Obama","The White House","1-234-567-8900",
"Barack.Obama#whitehouse.com","note"};
Integer image = images[0];
contact.putExtra("image", image);
contact.putExtra("details", details);
startActivity(contact);
}
if(position == 1){
Intent contact = new Intent(MainActivity.this, Details.class);
String[] details= new String[] {"Donald Trump","Trump Tower","1-234-567-8901",
"Donald.Trump#whitehouse.com","note"};
Integer image = images[1];
contact.putExtra("image", image);
contact.putExtra("details", details);
startActivity(contact);
}
if(position == 2){
Intent contact = new Intent(MainActivity.this, Details.class);
String[] details = new String[] {"Bill Clinton","New York","1-234-567-8902",
"Bill.Clinton#whitehouse.com","note"};
Integer image = images[2];
contact.putExtra("image", image);
contact.putExtra("details", details);
startActivity(contact);
}
if(position == 3){
Intent contact = new Intent(MainActivity.this, Details.class);
String[] details = new String[] {"Hillary Clinton","New Jersey","1-234-567-8903",
"Hillary.Clinton#whitehouse.com","note"};
Integer image = images[3];
contact.putExtra("image", image);
contact.putExtra("details", details);
startActivity(contact);
}
if(position == 4){
Intent contact = new Intent(MainActivity.this, Details.class);
String[] details= new String[] {"Joe Biden","OHIO","1-234-567-8903",
"Joe.Biden#whitehouse.com","note"};
Integer image = images[4];
contact.putExtra("image", image);
contact.putExtra("details", details);
startActivity(contact);
}
}
});
}
}
Second Activity I want to pass the array to
package com.example.androidlistview;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class Details extends Activity {
ListView list;
String []web={"Name:","Address:","Phone Number:","Email:","Note:"};
int image;
String[] details;
TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
// create the custom view
CustomList Adapter= new CustomList(Details.this, web, details);//, details should go here
// Get ListView object from xml
list=(ListView)findViewById(R.id.list);
//set adapter
list.setAdapter(Adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
}
});
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
image= bundle.getInt("image");
ImageView imageView = (ImageView) findViewById(R.id.imageView1);
imageView.setImageResource(image);
}
}
}
and the custom view i'm using for the Second Activity details
package com.example.androidlistview;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
public class CustomList extends ArrayAdapter<String>{
private final Activity mContext;
private final String[] web;
private final String[] details;
public CustomList(Activity mContext,String[] web, String[] details){ //, String[] details should go here
super(mContext, R.layout.list_single, web);
this.mContext=mContext;
this.web=web;
this.details=details;
}
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = mContext.getLayoutInflater();
View rowView= inflater.inflate(R.layout.list_single, null, true);
TextView txtTitle = (TextView) rowView.findViewById(R.id.txt);
txtTitle.setText(web[position]);
TextView txtTitle1 = (TextView)rowView.findViewById(R.id.txt1);
txtTitle1.setText(details[position]);
return rowView;
}
}

This is what i did to fix this
