How to search a custom listview

How to search a custom listview

So I have a custom listview with it's own adapter class, and the listview
has 2 textview's and one imageview. I want users to be able to click on
the search button in the action bar and search for either of the textviews
in my custom list. The problem is, I have no idea how to do this. If
anyone could help me, it'd be greatly appreciated. Thanks! Also a side
note: I'm using ActionBarSherlock
Here is the adapter for my listview:
public class ItemIDAdapter extends ArrayAdapter<String> {
private LayoutInflater mInflater;
private String[] mStrings;
private String[] mIds;
private TypedArray mIcons;
private int mViewResourceId;
public ItemIDAdapter(Context ctx, int viewResourceId,
String[] strings, String[] ids, TypedArray icons) {
super(ctx, viewResourceId, strings);
mInflater = (LayoutInflater)ctx.getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
mStrings = strings;
mIds = ids;
mIcons = icons;
mViewResourceId = viewResourceId;
}
@Override
public int getCount() {
return mStrings.length;
}
@Override
public String getItem(int position) {
return mStrings[position];
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = mInflater.inflate(mViewResourceId, null);
ImageView iv = (ImageView)convertView.findViewById(R.id.option_icon);
iv.setImageDrawable(mIcons.getDrawable(position));
TextView tv = (TextView)convertView.findViewById(R.id.option_text);
tv.setText(mStrings[position]);
TextView tv1 = (TextView)convertView.findViewById(R.id.itemids);
tv1.setText(mIds[position]);
return convertView;
}
}
And this is the class where I display the listview:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Context ctx = getApplication();
Resources res = ctx.getResources();
String[] options = res.getStringArray(R.array.item_ids);
String[] ids = res.getStringArray(R.array.item_names);
TypedArray icons = res.obtainTypedArray(R.array.item_images);
setListAdapter(new ItemIDAdapter(ctx, R.layout.idslistitem, ids,
options, icons));
}
