On xml layout you must use AutoCompleteTextView
Here link our XML file to the AutoCompleteTextView using a ArrayAdapter
Assume that the XML string-array you created is named as list_of_countries then it can be linked to your AutoCompleteTextView as follows:
Default ArrayAdapter filters only by the first characters. In case we want to see also words which contain the searching keyword, we need to use a custom ArrayAdapter and override its getView and getFilter methods.
MainActivity[MainActivity.class]
package com.androidfeeders.autocompletetextview;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
public class MainActivity extends AppCompatActivity {
private AutoCompleteTextView autoCompleteTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
autoCompleteTextView=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView);
ArrayAdapter adapterAutoComplete = new ArrayAdapter
(this, android.R.layout.select_dialog_item, OSVersion);
autoCompleteTextView.setAdapter(adapterAutoComplete);
// Single Character Search
autoCompleteTextView.setThreshold(1);
//Text Color addition
autoCompleteTextView.setTextColor(Color.BLUE);
}
//String Array
private static final String[] OSVersion = new String[]
{"Kitkat", "Lollipop", "Marshmallow", "Nougat", "Oreo"};
}
