    prefEditor = settings.edit();

    rowid=settings.getInt("rowid", 0);

    WayDataBase way=new WayDataBase(getApplicationContext());

    ArrayList<String> listvalues=way.getListDetails(rowid);
    if(listvalues.size()!=0)
    {
        ListView lv=getListView();
        ListAdapter adapter=new ArrayAdapter<String>(ListViewDetails.this, R.layout.view_animal_entry,listvalues);
        lv.setAdapter(adapter);
    }

view_animal_entry.xml

<?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="wrap_content"
android:orientation="vertical" >
    <TextView
    android:id="@+id/animalId"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:visibility="gone" />

   <TextView
       android:id="@+id/animalName"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:layout_marginBottom="5dp"
       android:layout_marginTop="5dp"
       android:paddingLeft="6dip"
       android:paddingTop="6dip"
       android:textColor="#A4C739"
       android:textSize="17sp"
       android:textStyle="bold" />

I think you should change your line from

ListAdapter adapter=new ArrayAdapter<String>(ListViewDetails.this, R.layout.view_animal_entry,listvalues);

To This

  ListAdapter adapter=new ArrayAdapter<String>(ListViewDetails.this, R.layout.view_animal_entry, R.id.animalName, listvalues);

This should work. You have to specifi a textview id to show data.

In the ArrayAdapter constructor, the textViewResourceId must refer to a TextView resource ID.

Can you show us your code, and ensure that it's the case ?

Taken from the javadoc :

By default this class expects that the provided resource id references a single TextView. If you want to use a more complex layout, use the constructors that also takes a field id. That field id should reference a TextView in the larger layout resource.

Edit : you second issue is a possible duplicate of ListView with rows containing a LinearLayout

It seems that you may avoid this Resources$NotFoundException: Resource ID #0x7f0a0154 type #0x12 is not valid message by using the default id :

in your layout XML :

<TextView android:id="@android:id/text1"/>

and in your code :

ListAdapter adapter=new ArrayAdapter<String>(ListViewDetails.this, android.R.id.text1, R.layout.view_animal_entry,listvalues);

(I'm not sure why a given ID does not work in that case)
