Question

This has been asked before but without an answer that works for me (and apparently one other given the comment on the accepted/only answer).

I have a ListView and I’ve implemented a long-press-to-copy for each item in the list. I’m filling in the list with my own adapter that sets the OnLongClickListener and it’s functioning fine except that when I touch and hold on an item, it doesn’t highlight at all and doesn’t fade. I haven’t set any events on the ListView and no other events on the View I return from my Adapter.

I’ve read about several fixes like not using wrap_content, setting clickable to false or removing it entirely from XML. Nothing has had an impact. I have noticed that if I remove my Long Click Listener that it will animate a click, but not a fading long click.

What can I do to preserve the long click fading animation on my ListView items?

FYI: the app is targeting Gingerbread (2.3.3)

EDIT:

I’m writing a simple hash calculator. It has one activity as follows:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <EditText
        android:id="@+id/Input"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:ems="10"
        android:inputType="text">
        <requestFocus/>
    </EditText>
    <Button
        android:id="@+id/Hash"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_below="@id/Input"
        android:onClick="StartHashes"
        android:text="@string/HashButtonText"/>
    <ListView
        android:id="@+id/HashList"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_below="@id/Hash">
    </ListView>
</RelativeLayout>

Relevant code from my onCreate method:

    Adapter = new HashEntryAdapter(this, Entries);// Entries is Vector<HashEntry>
    ListView list = (ListView)findViewById(R.id.HashList);
    list.setAdapter(Adapter);

HashEntry is simply a class containing 2 strings: the name of the hash and the resulting output of the hash called Name and Value respectively. The HashEntryAdapter is as follows:

public class HashEntryAdapter extends ArrayAdapter<HashEntry> {

    private Context context;

    public HashEntryAdapter(Context context, List<HashEntry> objects) {
        super(context, R.layout.hashitem, objects);
        this.context = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //data from your adapter
        HashEntry entry = getItem(position);
        //we want to reuse already constructed row views...
        if(convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.hashitem, null);
            convertView.setOnLongClickListener(new OnLongClickListener() {
                @Override
                public boolean onLongClick(View v) {
                    HashEntry entry = (HashEntry)v.getTag();
                    ClipboardManager clipboard = (ClipboardManager)v.getContext().getSystemService(Context.CLIPBOARD_SERVICE);
                    clipboard.setText(entry.Value);
                    Toast.makeText(context, entry.Name + " copied to clipboard", Toast.LENGTH_SHORT).show();
                    return true;
                }
            });
        }
        convertView.setTag(entry);

        TextView Name = (TextView)convertView.findViewById(R.id.HashName);
        TextView Value = (TextView)convertView.findViewById(R.id.HashValue);

        Name.setText(entry.Name);
        Value.setText(entry.Value);

        return convertView;
    }
}

And finally, hashitem.xml, a simple layout to put a grayed hash name over a black hash value:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/HashName"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:text="@string/HashNameFiller"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="@color/DarkGray"/>
    <TextView
        android:id="@+id/HashValue"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/HashName"
        android:layout_centerHorizontal="true"
        android:text="@string/HashValueFiller"
        android:textAppearance="?android:attr/textAppearanceMedium"/>
</RelativeLayout>

OnCreateContextMenu for vikki:

    list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
        @Override
        public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        }
    });

You could just use onCreateContextMenu like the stock messaging app does in ICS when you want to delete a conversation thread. You can get the id and position just like in onLongClickListener if you cast ContextMenuInfo to AdapterContextMenuInfo

import android.widget.AdapterView.AdapterContextMenuInfo

...

list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        AdapterContextMenuInfo contextInfo = (AdapterContextMenuInfo) menuInfo;
        int position = contextInfo.position;
        long id = contextInfo.id;
        // the child view who's info we're viewing (should be equal to v)
        View view = contextInfo.targetView;
    }
});
