gridview - Android, get specific fileld from grid item -

i have gridview specific griditem.xml contains few textview's

    <textview         android:id="@+id/title"         android:layout_width="wrap_content"         android:layout_height="wrap_content"/>      <textview         android:id="@+id/subtitle"         android:layout_width="wrap_content"         android:layout_height="wrap_content"/> 

this gridview filled data database. want filter hide items text in textview id="@+id/title" not equal typed myword,

        gridview mygridview   = (gridview) findviewbyid(r.id.mygridview);         gridviewadapter gridadapter  = new gridviewadapter(kategorie.this, r.layout.kategorie_grid_item, getdata(ds));         mygridview.setadapter(gridadapter); 

and getdata

private arraylist<imageitem> getdata(datasnapshot snapshot) {      (datasnapshot postsnapshot : snapshot.getchildren()) {          string key = postsnapshot.getkey();         map      v = (map) postsnapshot.getvalue();          string title      = (string) v.get("title");         string subtitle   = (string) v.get("subtitle");          myitems.add(new myitem(title, subtitle));      }       return myitems; } 

the list added adapter can make filtering on it. can show how added item gridview
