Introduction

This article explains how to use an array from string.xml in MultiAutoCompleteTextView.
The Android Text Control allows you to configure, style, and manipulate the controls in a variety of ways; we have many useful attributes we can use within the application to change the style, position and so on.
The four types of Text Controls in Android are:
MultiCompleteTextView: In this, when we enter a character regarding a predefined array, this will automatically show the list of items of the array. So in this application, we will show a list of animals that we will got from the string.xml file. In MultiCompleteTextView we will show this by writing this code:
  1. multiAutoCompleteTextView=(MultiAutoCompleteTextView)findViewById(R.id.multiAutoCompleteTextView);
  2. ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_dropdown_item_1line,getResources().getStringArray(R.array.ItemAraay));
  3. multiAutoCompleteTextView.setAdapter(adapter);
  4. multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

Step 2
Create an XML file and write this:
  1. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  2. xmlns:tools="http://schemas.android.com/tools"
  3. android:layout_width="match_parent"
  4. android:layout_height="match_parent"
  5. android:paddingLeft="@dimen/activity_horizontal_margin"
  6. android:paddingRight="@dimen/activity_horizontal_margin"
  7. android:paddingTop="@dimen/activity_vertical_margin"
  8. android:paddingBottom="@dimen/activity_vertical_margin"
  9. tools:context=".MainActivity">
  10. <TextView
  11. android:layout_height="wrap_content"
  12. android:layout_width="wrap_content"
  13. android:text="@string/app_name"
  14. android:textStyle="bold"
  15. android:layout_centerHorizontal="true"
  16. android:textSize="20dp"/>
  17. <MultiAutoCompleteTextView
  18. android:layout_width="fill_parent"
  19. android:layout_height="wrap_content"
  20. android:id="@+id/multiAutoCompleteTextView"
  21. android:completionThreshold="1"
  22. android:layout_marginTop="50dp"
  23. android:hint="enter alphabet"
  24. />
  25. </RelativeLayout>
Step 3
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <resources>
  3. <array name="ItemAraay">
  4. <item>Apple</item>
  5. <item>Ant</item>
  6. <item>Ass</item>
  7. <item>Bear</item>
  8. <item>Bat</item>
  9. <item>Ball</item>
  10. <item>Cat</item>
  11. <item>Crow</item>
  12. <item>cow</item>
  13. <item>Dog</item>
  14. <item>Dolphin</item>
  15. <item>Drum</item>
  16. </array>
  17. </resources>
Step 4
Create a Java file and write this:
  1. package com.multicompletetextview;
  3. import android.os.Bundle;
  4. import android.app.Activity;
  5. import android.view.Menu;
  6. import android.widget.ArrayAdapter;
  7. import android.widget.MultiAutoCompleteTextView;
  9. public class MainActivity extends Activity
  10. {
  11. MultiAutoCompleteTextView multiAutoCompleteTextView;
  13. @Override
  14. protected void onCreate(Bundle savedInstanceState)
  15. {
  16. super.onCreate(savedInstanceState);
  17. setContentView(R.layout.activity_main);
  18. multiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView);
  19. ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_dropdown_item_1line, getResources().getStringArray(R.array.ItemAraay));
  20. multiAutoCompleteTextView.setAdapter(adapter);
  21. multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
  23. }
  24. @Override
  25. public boolean onCreateOptionsMenu(Menu menu)
  26. {
  27. // Inflate the menu; this adds items to the action bar if it is present.
  28. getMenuInflater().inflate(R.menu.main, menu);
  29. return true;
  30. }
  32. }
