Question

I want to get TextView value from adapter and change it.

I have Button inside Adapter, and when i press that button, i want to change TextView value from inside adapter. Is that possible ?

Here is my adapter :

public class CustomGridView3 extends BaseAdapter {
    private ArrayList<ListItem> listData = new ArrayList<ListItem>();
    private LayoutInflater layoutInflater;
    private Context context;
    private int count = 0;
    CustomGridView3 adapter = this;
    int hargax,qtyx,totalx;
    public CustomGridView3(Context context, ArrayList<ListItem> listData) {
        this.listData = listData;
        layoutInflater = LayoutInflater.from(context);
        this.context = context;
    }

    @Override
    public int getCount() {
        return listData.size();
    }

    @Override
    public Object getItem(int position) {
        return listData.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder holder;
        if (convertView == null) {
            convertView = layoutInflater.inflate(R.layout.afterlogin_product_gridview, null);
            holder = new ViewHolder();
            holder.headlineView = (TextView) convertView.findViewById(R.id.nama_produk);
            holder.teaserView = (TextView) convertView.findViewById(R.id.harga);
            holder.imageView = (ImageView) convertView.findViewById(R.id.img_produk);
            holder.cmdMinus = (Button) convertView.findViewById(R.id.btn_min);
            holder.cmdPlus = (Button) convertView.findViewById(R.id.btn_plus);
            holder.qty = (TextView) convertView.findViewById(R.id.lbl_qty);
            holder.layout1 = (LinearLayout) convertView.findViewById(R.id.layout1);
            holder.harga = (TextView) convertView.findViewById(R.id.harga);
            holder.satuan = (TextView) convertView.findViewById(R.id.satuan);
            convertView.setTag(holder);

        } else {
            holder = (ViewHolder) convertView.getTag();
        }



        final ListItem newsItem = listData.get(position);
        String satuan = newsItem.getSatuan().toString();
        String harga = newsItem.getReporterName().toString();
        harga = "Rp. " + harga + " / " + satuan;
        holder.headlineView.setText(newsItem.getHeadline().toUpperCase());
        holder.teaserView.setText(harga);

        SharedPreferences pref = context.getSharedPreferences("MyPref", 0); // 0 - for private mode
        Integer qtys = Integer.parseInt(pref.getString(newsItem.getHeadline() + "_003", "0"));
        newsItem.setQuantity(qtys);
        holder.qty.setText(String.valueOf(newsItem.getQuantity()));
        String a = newsItem.getUrl();

        holder.cmdMinus.setTag(position);
        holder.cmdPlus.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                count = newsItem.getQuantity();
                count++;
                newsItem.setQuantity(count);
                holder.qty.setText("" + count);
                SharedPreferences pref = context.getSharedPreferences("MyPref", 0); // 0 - for private mode

                editor.commit();
            }
        });

        holder.cmdMinus.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                count = newsItem.getQuantity();

                    SharedPreferences.Editor editor = pref.edit();
                    editor.putString(newsItem.getHeadline() + "_001", newsItem.getReporterName()); // harga
                    editor.putString(newsItem.getHeadline() + "_002", newsItem.getHeadline());  //nama

                    editor.putString(newsItem.getHeadline() + "_005", newsItem.getUrl());  //url
                    editor.commit();

                    if(count == 0)
                    {
                        SharedPreferences prefs = context.getSharedPreferences("MyPref", 0); // 0 - for private mode
                        SharedPreferences.Editor editors = prefs.edit();
                        editors.remove(newsItem.getHeadline() + "_001");
                        editors.remove(newsItem.getHeadline() + "_002");
                        editors.remove(newsItem.getHeadline() + "_003");
                        editors.remove(newsItem.getHeadline() + "_004");
                        editors.remove(newsItem.getHeadline() + "_005");
                        editors.commit();
                        listData.remove(position);
                        adapter.notifyDataSetChanged();
                    }
            }
        });

        holder.qty.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                hargax = Integer.parseInt(newsItem.getReporterName());
                qtyx = newsItem.getQuantity();
                hargax = hargax * qtyx;
                if (context instanceof AfterLogin_Cart)
                {
                    ((AfterLogin_Cart)context).getPrice();
                }
            }

            @Override
            public void afterTextChanged(Editable s) {
            ***** Change TextView from Parent Activity *******
            }
        });

        if (holder.imageView != null) {
            //new ImageDownloaderTask(holder.imageView).execute(newsItem.getUrl());
            Picasso
                    .with(context)
                    .load(a)
                    .fit()
                    .noFade()
                    .into(holder.imageView);
        }

        return convertView;
    }

    static class ViewHolder {
        TextView headlineView;
        TextView teaserView;
        ImageView imageView;
        TextView qty;
        Button cmdPlus,cmdMinus;
        LinearLayout layout1;
        TextView harga,satuan;
    }

From addTextChangeListener, i want to change TextView value from parent's activity. What i have already searching for is just to execute some method.

 if (context instanceof AfterLogin_Cart)
 {
    ((AfterLogin_Cart)context).getPrice();
 }

Solution 1

The directory RECYCLER/S-1-5-21-1659004503-1644491937-725345543-1003 is presumably read-only. Run chmod -R u+w RECYCLER to set write permission on directories, then rm -rf RECYCLER.

If this is through a FUSE filesystem, it's possible that only the user who mounted the filesystem has write permission on it. In that case, run su user rm -rf RECYCLER.

Solution 2

This is due to an immutable attribute set for the files. If your filesystem driver allows it, run the command below before removing it.

chattr -i RECYCLER/S-1-5-21-1659004503-1644491937-725345543-1003/*
rm -f RECYCLER/S-1-5-21-1659004503-1644491937-725345543-1003/*

What is the drive mounted as?

[Admin]

Its automounted in /media as with NTFS as the FS

[Eliran Tutia]

You can create the adapter as an Inner Class in you Activity Class, and there you can reach easily the Textview and change it.

[x0r]

you can have TextWatcher as a variable in your adapter. Then upon adapter creation you pass this parameter from activity, which implements TextWatcher. And finally inside adapter you just delegate required methods to the TextWatcher instance

@EliranTutia I will try it

[Leonard Febrianto]

@R.Kirill Could you show how the code is ? Im stilld don't get it

Sorry, I dont have windows

[Gilles 'SO- stop being evil']

@user61954 NTFS is usually provided through FUSE (via ntfs-3g) these days, so try su user … (second paragraph of my answer).

[netvope]

If it's not going to be used on Windows again, I suggest you backup the useful files and reformat it with ext4 or other Linux-native filesystems.

[user61954]

The probelem is that its owner uses Windows :D

[user61954]

Installed ntfs-3g and now it works fine :)

@warren: What question does this not answer? The original question does not really ask a question. Implicitly, it asks, "How do I remove contents from a Windows disk?" Dubious is (somewhat anecdotally) answering, "Put the disk back on a Windows system and do it there." It's no less of an answer than Daniel's first answer. OK, yes, user61954 says that [s]he doesn't have Windows; hence Dubious's disclaimer that he hopes this will help someone else.

[David Yates]

@Scott - the question is about external hard drives and linux: Dubious' answer is about an SD card from an Android device that needed to be deleted using Windows. The answer has nothing to do with the question, and is barely tangentially similar.
