Try this simple answer:
find your button view by the tag you have set.
((Button) convertView.findViewWithTag(position)).setBackgroundColor(Color.GRAY);
You are encountering this problem because the last accept_btn object your adapter is holding is the last view object it created.
Therefore you are on the right track by setting a tag on the button. But then you have to retrieve that view by the tag.
Let me know if this is helpful.
Thanks.

I have written answer for same problem in gridview HERE. You can use same trick to solve this issue.
// Brief idea
You can implement your own custom OnClickListener and you can associate id/tag/position for each onclick of each item of listview.
yourBtn.setOnclickListener(new BtnClick(position, btnid));
Custom OnclickListener:
Class BtnClick View.OnClickListener
{
int position;
int btnId;
Public BtnClick(int position, int id)
{
this.position = position;'
this.btnId = btnId;
}
#Override
public onClick(View v)
{
// You can add logic here for each item clicked using position and id of each item you passed in constructor
}
}

Android getting the EditText value from an AlertDialog in a Fragment

I am getting a null pointer exception when I click the OK button. and I am trying to get the value form an EditText in an AlertDialog. I am calling the AlertDialog from a fragment.
I believe this line is the problem
View promptView = layoutInflater.inflate(R.layout.passchange_dialog, null);
I think it is because I am passing null but I am not sure what eles to pass. Please note I am calling the AlertDialog from a fragment not an Activity.
public class fragment_account extends myFragment {
private final String firebase = "https://xxxxxxxx.firebaseio.com";
private String email = "";
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_account, container, false);
SharedPreferences sp = getActivity().getPreferences(0);
TextView address = (TextView) view.findViewById(R.id.textViewEmailAddress);
email = sp.getString("email", "");
address.setText(email);
ImageView imageChangePass = (ImageView) view.findViewById(R.id.imageChangePass);
imageChangePass.setOnClickListener(
new View.OnClickListener() {
public void onClick(View v) {
showInputDialog(v);
}
}
);
return view;
}
protected void showInputDialog(final View view) {
try
{
LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
View promptView = layoutInflater.inflate(R.layout.passchange_dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(view.getContext());
alertDialogBuilder.setView(promptView);
alertDialogBuilder.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
EditText edittextOldPass = (EditText) view.findViewById(R.id.edittextOldPass);
EditText edittextNewPass = (EditText) view.findViewById(R.id.edittextNewPass);
EditText edittextConfirmPass = (EditText) view.findViewById(R.id.edittextConfirmPass);
final String oldPass = edittextOldPass.getText().toString().trim();
final String newPass = edittextNewPass.getText().toString().trim();
final String confirmPass = edittextConfirmPass.getText().toString().trim();
Firebase ref = new Firebase(firebase);
ref.changePassword(email, oldPass, newPass, new Firebase.ResultHandler() {
#Override
public void onSuccess() {
}
#Override
public void onError(FirebaseError firebaseError) {
}
});
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}
catch (Exception e)
{
Log.i("myStuff", e.getMessage());
}
}
}
Any help or suggestions would be greatly appreciated. Thanks

I think you should call findViewById on promptView instead of on view variable

I guess you should initialize all those textview's before setting the layout of your dialog instead of inside your onClick method. As you have to access their values, you'll have to declare them final in order to get what the user typed in inside of your onClick function.

You can't add values in getView. let's do it in activity

how to disable button in listview

I am new to Android development and I am having a hard time wrapping my head around the android listviews. I pretty much went through entire google search and tried every "possible" solution, but without really getting the listview, I am having a hard time solving this problem.
I want to disable particular button when I click the complete_btn in listview item.
Right now, the complete_btn.setOnClickListener in the else {} part is giving me the null pointer exception (it's fine in the if(converView == null) part). If I remove the code, everything works fine, but even simply commenting out everything in the listener does not work.
I want to eventually disable the button if Yes is clicked in the Alert dialog that pops up when the button is pressed! Could someone please help me with this??

Add
Button button = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
button.setEnabled(false);
inside
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
}
method like :
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Button button = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
button.setEnabled(false);
try{
SmsManager smsManager = SmsManager.getDefault();
if (message_finish.length() > 60) {
ArrayList<String> contents = smsManager.divideMessage(message_finish);
for(int j = 0; j<contents.size(); j++){
smsManager.sendTextMessage(phone_str, null, contents.get(j), null, null);
}
} else {
smsManager.sendTextMessage(phone_str, null, message_finish, null, null);
}
}catch (Exception e){

Setting TextViews from an onClick(View v) within an onClick(View v)?

This line will not set, holder.t1.setText(NewItem);
If I move it to the parent onClick, with a hardcoded string (for testing) it does.
Keep in mind, this is inside a getView method of an ArrayAdapter. I am trying to setText to ListView rows.
Edit:
EXPANDED, COMPLETE getView() -- AS REQUESTED
(Did not have time to edit, will later, sorry!)

From what you've said in the above comments, this is the intended function. Since,
Except, the dialog does dismiss, I get the toast and the task runs correctly.
This is coded into your onClick() here:
bInsert.setOnClickListener(new OnClickListener() {
#SuppressWarnings("unchecked")
public void onClick(View v) {
NewItem = etEdit.getText().toString();
if (NewItem.equals("")) {
Toast.makeText(getContext(),
"Please add something first.",
Toast.LENGTH_SHORT).show();
} else {
holder.t1.setText(NewItem);
passing.add(NewItem);
dialog.dismiss();
new EditCommentTask().execute(passing);
}
}
});
Specifically, this is executing:
if (NewItem.equals("")) {
Toast.makeText(getContext(),
"Please add something first.",
Toast.LENGTH_SHORT).show();
}
so I am assuming your problem is with NewItem, I never see where you actually initialize it, but I am assuming it .equals("") since this is executing. Try throwing a Log.d or println() just below the line NewItem = etEdit.getText().toString(); to see what the value of NewItem is at this point.
