Try this code

public class MainActivity extends Activity {
AutoCompleteTextView text;
String[] languages={"Android ","java","IOS","SQL","JDBC","Web services"};

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  text=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);

  ArrayAdapter adapter = new 
     ArrayAdapter(this,android.R.layout.simple_list_item_1,languages);

  text.setAdapter(adapter);
  text.setThreshold(1);

} }

and use 'AutoCompleteTextView' in place text view or edit text and for more help refer below mentioned link https://www.tutorialspoint.com/android/android_auto_complete.htm
