从Spinner获取选定的值

Question

我制作了一个滑块，参考this教程。我做了一些改变。我为每个图像添加了一个微调器和一个editText，以便用户可以输入内容并选择提供的选项。

我Acitvity是这样的：

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是这样的：

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; 
    } 

    ... 
    ... 
} 

我的活动在操作栏和按钮上点击我要访问的两个按钮所有微调和编辑文本的信息。我不知道得到它。我试过它：

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

但上述代码只返回一个值。 我如何获得所有设置的微调器。

Answer 1

尝试重写以下功能：

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

然后你就可以使用该功能

mSpinner.getSelectedItem(); 

- 编辑 - 获得选择的值就可以得到所选择的位置（整数）然后从它的适配器/值的数组中获得值

mSpinner.getSelectedItemPosition(); 

祝你好运
