使用 AutoCompleteTextView 代替 EditText：

 <AutoCompleteTextView
            android:id="@+id/Months"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dip"
            android:layout_marginRight="10dip"
            android:textStyle="bold"
            android:width="250dip" /> 

 import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;

public class AutoCompleteString extends Activity implements  OnItemClickListener, OnItemSelectedListener  {


    // Initialize variables

    AutoCompleteTextView textView=null;
    private ArrayAdapter<String> adapter;

    //These values show in autocomplete
    String item[]={
              "January", "February", "March", "April",
              "May", "June", "July", "August",
              "September", "October", "November", "December"
            };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle bundle) {
        super.onCreate(bundle);

        setContentView(R.layout.auto_complete_string);


        // Initialize AutoCompleteTextView values

            // Get AutoCompleteTextView reference from xml
            textView = (AutoCompleteTextView) findViewById(R.id.Months);

            //Create adapter    
            adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, item);

            textView.setThreshold(1);

           //Set adapter to AutoCompleteTextView
            textView.setAdapter(adapter);
            textView.setOnItemSelectedListener(this);
            textView.setOnItemClickListener(this);


    }


    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int position,
            long arg3) {
        // TODO Auto-generated method stub
        //Log.d("AutocompleteContacts", "onItemSelected() position " + position);
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

        InputMethodManager imm = (InputMethodManager) getSystemService(
                INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

    }

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        // TODO Auto-generated method stub

        // Show Alert       
        Toast.makeText(getBaseContext(), "Position:"+arg2+" Month:"+arg0.getItemAtPosition(arg2),
                Toast.LENGTH_LONG).show();

        Log.d("AutocompleteContacts", "Position:"+arg2+" Month:"+arg0.getItemAtPosition(arg2));

    }

    protected void onResume() {
        super.onResume();
    }

    protected void onDestroy() {
        super.onDestroy();
    }

}
