public View getView(int position, View child, ViewGroup parent) {

    Holder holder;

    LayoutInflater layoutInflater;

    if (child == null) {
        layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        child = layoutInflater.inflate(R.layout.listviewdatalayout, null);

        holder = new Holder();

        holder.account_master_name = (TextView) child.findViewById(R.id.account_master_name);
        holder.account_master_add = (TextView) child.findViewById(R.id.account_master_add);

        child.setTag(holder);

    } else {

        holder = (Holder) child.getTag();
    }
    holder.account_master_name.setText(id.get(position)+ "\t"+ name.get(position));
    holder.account_master_add.setText(add1.get(position)+""+add2.get(position)+city.get(position));

    return child;
}

public class Holder {
    TextView account_master_name;
    TextView account_master_add;
}

}

Do you mean you type in a name and then only show names containing the letters? — Janwilx72, Jun 07 '19 at 09:49

List<ListAdapter> filterList = new ArrayList<>();
List<ListAdapter> allList = new ArrayList<>();

//Add Data to list

filterList.clear();
for (ListAdapter listItem : allList)
{

    if(listItem.name.contains("yourText")
    {
       filterList.add(listItem);
    {
}

Then you display filterList in your ListView

You could try and run a filter on the Adapter when like this:

Untested Code

EditText search = findViewById(R.id.search); search.addTextChangedListener(new TextWatcher() {

    public void onTextChanged(CharSequence s, int start, int before, int count) {
        listAdapter.getFilter().filter(s);
        listAdapter.notifyDataSetChanged();

    }

    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
    public void afterTextChanged(Editable s) {}
});
