Good answer is there, but still there are some issues(wrong position when onclick, serchview text overlay) as mentioned in comment section, so you can also do this by following way

Reference for more info : searchview listview android

I have tested it and don't find any issue so far, If you find any, please mention in comment section.

Model class: MovieNames.java

public class MovieNames {
    private String movieName;

    public MovieNames(String movieName) {
        this.movieName = movieName;
    }

    public String getAnimalName() {
        return this.movieName;
    }

}

2 : listview_item.xml file :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp">


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

</RelativeLayout>
