Autocomplete TextView and Multi Autocomplete TextView

 Autocomplete TextView and Multiple AutocompleteTextView:-

Autocomplete is used to provide autosuggestion text according to input char, if we want to get suggestions  for multiple word using comma or another separator that is called tokenizer then we can implement multi Autocomplete Textview for multiple searching of data.

AutoCompleteTextView Example:-

package com.example.customdrawer;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class MainActivity3 extends AppCompatActivity {

    AutoCompleteTextView act;
    String course[] = {"JAVA",".NET","PHP","iOS","Android","Android Advance"," JAVA Advance", "J2SE","J2EE"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main3);
        act =(AutoCompleteTextView)findViewById(R.id.autocomplete2);
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.select_dialog_item,course);
        act.setThreshold(1);
        act.setAdapter(aa);
       //
        //act.setAdapter(aa);


    }
}

Code of design file:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
