AutoCompleteView未使用我的阵列

Question

我正在与AutoCompleteTextView挣扎。类训练调用类getAddress，其中包含几个功能正常的editText和有效的微调器。 AutoCompleteTextView未列出我的数组中的项目。这是我的文件：

address_list.xml

 <AutoCompleteTextView 
        android:id="@+id/autoCompleteRoadNames" android:text=""

</RelativeLayout>

这是 getAddress

类

public class getAddress extends Activity 
{
/* Called when the activity is first created. */
private ListView lv1;
private String locomotiveAddress[],locomotiveFx[];
private EditText newAddress;
private TextView newAddressText;
private Button deleteButton, editButton;
private long deleteRow=0;
private boolean editFlag;                   // used to determine on "DONE' key pressed whether  a new address was entered or an edit was done

@Override
public void onCreate(Bundle savedInstanceState) 
{

locomotiveFx=new String[13];                    // need to keep for rewriting on changes to list  
locomotiveAddress=new String[13];               // allow 12 address saved 
locomotiveAddress[0]="New Address";
editFlag=false;

// Read from file objectTrains.txt and restore locomotive and manufacturer list  
InputStream fHandle;
try 
  {
  fHandle = openFileInput("objectTrains.txt");
  InputStreamReader inputreader = new InputStreamReader(fHandle);
  BufferedReader buffreader = new BufferedReader(inputreader);
  String line="";

  int x;
  for (x=1; x<13; x++)
    {
    line = buffreader.readLine();
    if (line == null)
      {
      locomotiveAddress[x]="";
      locomotiveFx[x]="";
      }
    else
      {
      String[] item = (line).split(",");                                               // array items[] contains comma delimited items in file
      locomotiveAddress[x]=("Locomotive "+item[0]+" "+item[1]+" ");                 // get the first item, or locomotive number
      locomotiveFx[x]=(item[2]);                                                // get Function key status
      }
    }
  fHandle.close();
  }
catch (FileNotFoundException e2) 
  {
  e2.printStackTrace();
  }
catch (IOException e) 
  {
  e.printStackTrace();
  }

super.onCreate(savedInstanceState);
setContentView(R.layout.address_list);

/* manufacturer list */
Spinner manufacturer = (Spinner) findViewById(R.id.manufacturerSpinner);
ArrayAdapter<CharSequence> manufactureAdapter = ArrayAdapter.createFromResource(this, R.array.manufacturer, android.R.layout.simple_spinner_item);
manufacturer.setAdapter(manufactureAdapter);



/* road name list */
findViewById(R.id.autoCompleteRoadNames);
R.layout.list_item, locoNames);
AutoCompleteTextView acTextView = (AutoCompleteTextView)
 findViewById(R.id.autoCompleteRoadNames);
ArrayAdapter roadNamesAdapter = new ArrayAdapter(this,      android.R.layout.simple_dropdown_item_1line, locoNames);
android.R.layout.simple_dropdown_item_1line, locoNames);
acTextView.setThreshold(3);
acTextView.setAdapter(roadNamesAdapter);
R.array.roadNames, android.R.layout.simple_spinner_item);


static final String[] locoNames = new String[]{
        "This is the first line that is too long and it needs to wrap content",
     "Albania", "Algeria", "American Samoa", "Andorra",
      "zawer",
          "Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium"
    };   

locoNames已经在几个不同的地方声明了几种不同的方式。任何想法都会受到欢迎。谢谢！
