活動微調和切換按鈕

Question

我正在構建一個應用程序&這是我的應用程序的設置頁面（活動視圖）是this。
我用一個Toggle Button & Spinner。

當切換按鈕被選中時，該應用程序的所有其他用戶都可以看到用戶配置文件&未選中時處於隱藏狀態。

從Spinner選項中，用戶可以通過選擇距離來搜索他/她周圍的其他用戶。

我的問題是什麼 - >當應用程序正在運行這些設置工作，但是當我重新啓動我的應用程序用戶的以前的設置迷路（即，這不是持久&再次我必須做這些設置）...如何我可以從這個問題中解脫出來。我代碼是 - >

public class Settings extends Activity implements OnCheckedChangeListener, OnItemSelectedListener { 
ToggleButton tgb; 
Spinner redai; 

final String[] dis_option= new String[]{"1 mile","5 miles","10 miles","All"}; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.settings); 

    //Toggle Button 
    tgb = (ToggleButton) findViewById(R.id.settings_visibility); 
    tgb.setOnCheckedChangeListener(this); 

    //Spinner 
    redai=(Spinner)findViewById(R.id.settings_redai); 
    ArrayAdapter<String> sel_dis=new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, dis_option); 
    sel_dis.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    redai.setAdapter(sel_dis); 
    redai.setOnItemSelectedListener(this); 

} 

@Override 
public void onItemSelected(AdapterView<?> parent, View v, int position, 
     long id) { 
    // TODO Auto-generated method stub 
    String temp_nearBy=parent.getItemAtPosition(position).toString(); 

    /** preference that write the selected distance for further references in other Activities */ 
    SharedPreferences nearByDistanceWrite = getSharedPreferences("nearBy", MODE_WORLD_READABLE); 
    SharedPreferences.Editor edit = nearByDistanceWrite.edit(); 
    edit.putString("upToDistance", temp_nearBy); 
    edit.commit(); 
    Log.i("Settings_Spinner", "onItemSelected_pref_edited..."+temp_nearBy); 
} 

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

} 

@Override 
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
    // TODO Auto-generated method stub 
    if (!isChecked) { 
     buttonView.getContext(); 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setMessage("Are you sure you want to Hide Your Profile?") 
       .setCancelable(false) 
       .setPositiveButton("Yes", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 


        //here, I pass Visibility as '0' which means profile of fan is Hidden & not seen to other fans! 
         setVisibility(0);//Method which set Connection with sever & set the visibility of user profile accordingly 

         /** Here you have to write code to set device token as '0' to hide the Profile of Fan! */ 
         final ProgressDialog pg= ProgressDialog.show(Settings.this, "Progress...", "please wait updating settings!",true); 
         Toast.makeText(Settings.this,"Your Profile Set Hidden Successfully!", Toast.LENGTH_LONG).show(); 
        } 
       }) 
       .setNegativeButton("No", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         //setting toggle button to unchecked 
         ToggleButton tg=(ToggleButton)findViewById(R.id.settings_visibility);//buttonView.setChecked(false); 
         tg.setChecked(true); 

         dialog.cancel(); 

        } 
       }); 
     AlertDialog alert = builder.create(); 
     alert.show(); 
    } else { 
     //here, I pass Visibility as '1' which means profile of fan is visible to other fans 
     setVisibility(1); 
     Toast.makeText(Settings.this,"Your Profile get Visible Successfully!", Toast.LENGTH_SHORT).show(); 
    } 
} 


@Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume(); 


    Log.i("Settings_onResume", "onresume_after(new)..."+nearBy); 

} 

/** Method that set connection with server & Set the visibility of Fan Profile to either Visible(1) or Hidden(0) 
* @param visibility : The int value which indicate to set profile of a Fan to be Visible or Hidden. */ 
private void setVisibility(int visibility) { 
//...more code ... 

} 

} 

我怎樣才能得到這些Settings（舊的設置還是我以前的設置），當我重新啓動我的應用程序... ??? &

我怎樣才能使Spinner視圖更醒目&好看（系統微調並不好看）???

我高興有pointers或code snippets來解決這個問題！

如果這是一個應用程序，您應該使用您的SharedPreferences返回這些值。這正是他們應該使用的。訪問與此特定應用相關的數據。
