我已遵循其餘部分的說明here。但是,這似乎是我的編碼問題。最初,當我第一次到達這個活動時,我的小工具應該在列表中顯示第一個項目,但不是隻是空的。幸運的是,當我點擊微調器來做出我的選擇時,該列表仍然存在。而且,在我做出選擇後,敬酒並沒有出現。我不知道這是否是它,因爲它彈出在DDMS後,我有讓我選擇的原因:從微調框中獲取所選項目

下面是本次活動的編碼:

package android.wps;

import android.os.SystemClock;

import android.widget.Toast; 
import android.widget.AdapterView.OnItemSelectedListener; 

public class locationFinder extends Activity { 

WifiPositioningServices wifiPositioningServices = new WifiPositioningServices(); 

ArrayList<Profile> profileList = new ArrayList<Profile>(); 
ArrayList<String> profileNames = new ArrayList<String>(); 
ArrayList<String> mapNames = new ArrayList<String>(); 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.locationfinder); 

    String[] temp = wifiPositioningServices.GetAllProfileData(); 

    final Spinner profiles = (Spinner)findViewById(R.id.profileList); 

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, 
      android.R.layout.simple_dropdown_item_1line, 
      profileNames); 
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    profiles.setAdapter(spinnerArrayAdapter); 

    profiles.setOnItemSelectedListener(new OnItemSelectedListener() { 

     @Override 
     public void onItemSelected(AdapterView<?> parent, View view, 
       int pos, long arg3) { 
      // TODO Auto-generated method stub 
      String test = parent.getItemAtPosition(pos).toString(); 
      Toast toast = Toast.makeText(parent.getContext(), test, Toast.LENGTH_SHORT); 
      toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); 
      toast.show(); 
     } 

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

     } 
    }); 

    //store all profile data into a ArrayList of Profile objects 
    for(int i=0; i<temp.length; i++){ 
     String[] result = temp[i].split(","); 
     Profile profile = new Profile(); 
     profile.setProfileName(result[0]); 
     profile.setOwner(result[1]); 
     profile.setMap(result[2]); 
     profile.setVisible(result[3]); 
     boolean visible = Boolean.valueOf(result[3]); 
     if(visible){ 
      //if visible is true, then add profile name and mac filters into arraylist 
      profileNames.add(result[0]); 
      for(int j=4; j<result.length; j++){ 
       profile.setMacFiltersList(result[j]); 
      } 
     } 
     profileList.add(profile); 
    } 
} 

}

發佈您的代碼。 –

您發佈的代碼部分似乎沒問題。所以錯誤應該是其他地方... –

嗨@Nishant,我已經更新了我的問題與編碼。 – user918197

奇怪。在將整個for循環的段落移到頂端之前,在微調器的初始化代碼之前,現在一切都好了。項目在選擇之前/之後顯示在微調器中,並且在選擇完成後確實出現了烤麪包。

for循環,我這裏指的是

for(int i=0; i<temp.length; i++){ 
    String[] result = temp[i].split(","); 
    Profile profile = new Profile(); 
    profile.setProfileName(result[0]); 
    profile.setOwner(result[1]); 
    profile.setMap(result[2]); 
    profile.setVisible(result[3]); 
    boolean visible = Boolean.valueOf(result[3]); 
    if(visible){ 
     //if visible is true, then add profile name and mac filters into arraylist 
     profileNames.add(result[0]); 
     for(int j=4; j<result.length; j++){ 
      profile.setMacFiltersList(result[j]); 
     } 
    } 
    profileList.add(profile); 
}
