android edittext with drop down list

Question

I have an edittext which gets values from the user. I want to add an option which allows the user to choose from different options via drop down list when edittext is clicked. Does anyone have an idea how to do this?

This is edittext code:

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textPersonName"
    android:ems="10"
    android:id="@+id/dish_quantity"
    android:layout_below="@+id/dish_name"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    android:hint="Quantity" />

I want it to look like this:

I think this is your requirement:

just follow this example: Xml:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >   
<AutoCompleteTextView
    android:id="@+id/languages"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"></AutoCompleteTextView>
</LinearLayout>

Activity:-

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

public class MainActivity extends Activity {

    String[] languages = { "C","C++","Java","C#","PHP","JavaScript","jQuery","AJAX","JSON" };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
                //Create Array Adapter
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.select_dialog_singlechoice, languages);
                //Find TextView control
        AutoCompleteTextView acTextView = (AutoCompleteTextView) findViewById(R.id.languages);
        //Set the number of characters the user must type before the drop down list is shown
                acTextView.setThreshold(1);
                //Set the adapter
        acTextView.setAdapter(adapter);
    }
}

I think what you are looking for can be done with a Spinner instead of an EditText.

Here's a detailed explanation of how to use it.
