從Spinner獲取選定的值

Question

我製作了一個滑塊，參考this教程。我做了一些改變。我爲每個圖像添加了一個微調器和一個editText，以便用戶可以輸入內容並選擇提供的選項。

我Acitvity是這樣的：

public class Details extends Activity{ 

    ... 
    ... 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     session = new SessionMngr(getApplicationContext()); 
     cart = new ShoppingCart(getApplicationContext()); 

     uid = session.getIntValues("uid"); 

     selectedItems = new ArrayList<String>(); 

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

     selectedItems = cart.getCartImages(); 

     viewPager = (ViewPager) findViewById(R.id.pager); 

     Intent i = getIntent(); 
     int position = i.getIntExtra("position", 0); 
     adapter = new FullScreenImageAdapter(Details.this, selectedItems); 
     viewPager.setAdapter(adapter); 

     viewPager.setCurrentItem(position); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu){ 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.details_action_bar, menu); 
     return super.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 

     nvpSizes = new ArrayList<NameValuePair>(); 
     for(int i=0;i<selectedItems.size();i++){ 
      nvpSizes.add(new BasicNameValuePair("1", "1")); //qty , sizeId 
     } 

     switch(item.getItemId()){ 
      case R.id.action_check_out: 
       dialog = ProgressDialog.show(this, "", "Please wait. Uploading file...",true); 
       new Thread(new Runnable(){ 
        public void run(){ 
         UploadFile(selectedItems, nvpSizes); 
        } 
       }).start(); 
       break; 
      case R.id.action_add_more: 

       // I want to get the Scanner value and editText value of all the scanners and editTexts here 

       Intent intent = new Intent(Details.this, Dashboard.class); 
       startActivity(intent); 
       break; 
      default: 
       break; 
     } 

     return super.onOptionsItemSelected(item); 
    } 

    ... 
    ... 
} 

我FullScreenImageAdapter是這樣的：

public class FullScreenImageAdapter extends PagerAdapter { 

    public FullScreenImageAdapter(Activity activity, 
      ArrayList<String> imagePaths) { 
     this._activity = activity; 
     this.context = _activity.getApplicationContext(); 
     this._imagePaths = imagePaths; 
    } 

    ... 
    ... 

    @Override 
    public Object instantiateItem(ViewGroup container, int position) { 
     ImageView imgDisplay; 
     inflater = (LayoutInflater) _activity 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View viewLayout = inflater.inflate(R.layout.layout_fullscreen_image, container, 
       false); 

     imgDisplay = (ImageView) viewLayout.findViewById(R.id.imgDisplay); 

     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this._activity, 
       android.R.layout.simple_spinner_item, sizes); 

     Spinner mSpinner = (Spinner) viewLayout.findViewById(R.id.sizes); 

     adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
     mSpinner.setAdapter(adapter); 

     BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inPreferredConfig = Bitmap.Config.ARGB_8888; 
     Bitmap bitmap = BitmapFactory.decodeFile(_imagePaths.get(position), options); 
     imgDisplay.setImageBitmap(bitmap); 

     ((ViewPager) container).addView(viewLayout); 

     return viewLayout; 
    } 

    ... 
    ... 
} 

我的活動在操作欄和按鈕上點擊我要訪問的兩個按鈕所有微調和編輯文本的信息。我不知道得到它。我試過它：

Spinner mSpinner = (Spinner) viewLayout.findViewById(R.id.sizes); 
mSpinner.getSelectedItem(); 

但上述代碼只返回一個值。 我如何獲得所有設置的微調器。

Answer 1

嘗試重寫以下功能：

mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { 
      mSpinner.setSelection(i, true); 
     } 

然後你就可以使用該功能

mSpinner.getSelectedItem(); 

- 編輯 - 獲得選擇的值就可以得到所選擇的位置（整數）然後從它的適配器/值的數組中獲得值

mSpinner.getSelectedItemPosition(); 

祝你好運
