make it right it if it correct.

Android - Multiple selection in ListView

Basically, you can have a hashset that contains only the selected items. The code would look like this

public class MylibmanList extends BaseAdapter {
    private Activity activity;
    private ArrayList<HashMap<String, String>> data;
    private static LayoutInflater inflater=null;

    HashSet<String> selectedBooks = new HashSet<String>();

    //This listener will be used on all your checkboxes, there's no need to 
    //create a listener for every checkbox.
    CompoundButton.OnCheckedChangeListener checkChangedListener = new CompoundButton.OnCheckedChangeListener{
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                String bookDuration = (String) buttonView.getTag();
                if(isChecked){
                    selectedBooks.add(bookDuration);
                }else{
                    selectedBooks.remove(bookDuration);
                }
            }
    }

    public MylibmanList(Activity a, ArrayList<HashMap<String, String>> d) {
        activity = a;
        data=d;
        inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    static class ViewHolder {
        TextView title;
        TextView artist;
        TextView duration;
        CheckBox check;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if(convertView==null){
            convertView = inflater.inflate(R.layout.listrow_row, null);

            holder = new ViewHolder();
            holder.title = (TextView) convertView.findViewById(R.id.title);
            holder.artist = (TextView) convertView.findViewById(R.id.artist);
            holder.duration = (TextView) convertView.findViewById(R.id.duration);
            holder.check = (CheckBox) convertView.findViewById(R.id.check);

            holder.check.setOnCheckedChangeListener(checkChangedListener);

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

        HashMap<String, String> book = new HashMap<String, String>();
        book = (HashMap<String, String>) getItem(position);

        holder.check.setTag(book.get(ShowList.LIST_KEY_ID));

        holder.title.setText(book.get(ShowList.LIST_KEY_NAME));
        holder.artist.setText(book.get(ShowList.LIST_KEY_WRITER));
        holder.duration.setText(book.get(ShowList.LIST_KEY_ID));

        boolean bookSelected = false;
        if(selectedBooks.contains(book.get(ShowList.LIST_KEY_ID))){
            bookSelected = true;
        }

        holder.check.setChecked(bookSelected);

        return convertView;
    }

I've changed your getView abit. The viewHolder will now be created only once for each view (as it should). Also, if its not too much of a hustle, you should create a class for your book. Something like

Class Book{
    String title;
    String artist;
    Long duration;
}

How can I select multiple textViews from the collection of textViews which is not in listview on long pressing

I assume you want to highlight textview when selected on long press. Try this:

textView.setOnLongClickListener(new View.OnLongClickListener() {

        @Override
        public boolean onLongClick(View view) {
             boolean selected = !view.isSelected();
             view.setSelected(selected);
             view.setBackgroundColor(selected ? Color.RED : Color.TRANSPARENT);
             return true;
        }
    });

Selecting/highlighting multiple items in listview with custom adapter - Android

  1. The root View of each item you will display in list must implement Checkable. When implementing this interface also update the drawable state of View. See this answer for how to do that.

  2. Set a <selector> drawable as background for this root View. Which different color/drawables for checked state and normal states.

  3. Set ListView's choice mode to single choice or multi-choice.

  4. In list adapter, provide item views with above created View as parent layout.

Now, ListView will take care of setting checked/unchecked state on its item views. Also you can call getCheckedItemIds() or getCheckedItemPositions() on ListView to get currently selected items.

Multiple TextViews in the same List Item

This link uses Multiple Texts in a Single Listview...

http://publicstaticdroidmain.com/2011/12/building-a-custom-multi-line-listview-in-android/

Use the Code as follow..

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical|center_horizontal"
    android:text="Custom ListView Example" />

<ListView
    android:id="@+id/srListView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

</LinearLayout>

and,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingBottom="10dip"
android:paddingLeft="10dip"
android:paddingTop="10dip" >

<TextView
    android:id="@+id/name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#C20000"
    android:textSize="14sp"
    android:textStyle="bold" />

<TextView
    android:id="@+id/cityState"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<TextView
    android:id="@+id/phone"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

</LinearLayout>

Multiple Items Selected on ListView, selects wrong items

You can use the following adapter to achieve your goal.

Remove android:entries="@array/list_inventario" in your Listview and add choicemode as follows in your XML.

<ListView 
    android:id="@+id/list_inv"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:choiceMode="multipleChoice">
</ListView>

InventarioFragment

public class InventarioFragment extends Fragment {

private Activity activity;

private String[] inventatioItems;

@Override

}

    listInventario = (ListView) view.findViewById(R.id.list_inv);
    inventatioItems=getResources().getStringArray(R.array.list_inventario);

    InverntarioAdapter adapter=new InverntarioAdapter(activity);
    listInventario.setAdapter(adapter);
    listInventario.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View v, int pos, long arg3) {
            listInventario.setItemChecked(pos, true);;  
        }
    });

    return view;
}

private class InverntarioAdapter extends BaseAdapter{

    private LayoutInflater inflator;

    public InverntarioAdapter(Context context){
