我在其中，當用戶選擇一個值的微調，在onItemSelectedListener打開一個對話框，把更多的細節

private AdapterView.OnItemSelectedListener spinnerListeners=new AdapterView.OnItemSelectedListener(){ 
    @Override 
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
     switch (parent.getId()){ 
      case R.id.puttSpinner: 
       // open dialog to enter Additional putt Stats 
       if(position > 0) { 
        AlertDialog.Builder alertDialog = new AlertDialog.Builder(v.getContext()); 
        LinearLayout layout = new LinearLayout(v.getContext()); 
        LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,  LinearLayout.LayoutParams.WRAP_CONTENT);layout.setOrientation(LinearLayout.VERTICAL);layout.setLayoutParams(parms); 
        layout.setGravity(Gravity.CLIP_VERTICAL); 
        layout.setPadding(2, 2, 2, 2); 
        for (int i=1;i<position+1;i++){ 
         LinearLayout ll = new LinearLayout(v.getContext()); 
         LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(
           LinearLayout.LayoutParams.MATCH_PARENT, 
           LinearLayout.LayoutParams.WRAP_CONTENT); 
         ll.setOrientation(LinearLayout.HORIZONTAL); 
         ll.setLayoutParams(llp); 
         TextView tv = new TextView(v.getContext()); 
         tv.setText("Putt "+String.valueOf(i)+":"); 
         tv.setPadding(40, 40, 40, 40); 
         tv.setGravity(Gravity.CENTER); 
         tv.setTextSize(20); 
         LinearLayout.LayoutParams tvParams = new LinearLayout.LayoutParams(
           LinearLayout.LayoutParams.MATCH_PARENT, 
           LinearLayout.LayoutParams.WRAP_CONTENT); 
         tvParams.bottomMargin = 5; 
         //ll.addView(tv,tvParams); 
         ll.addView(tv); 

         Spinner s = new Spinner(v.getContext()); 
         String[] puttDistList = getResources().getStringArray(R.array.putt_dist_list); 
         s.setAdapter(new ArrayAdapter<String>(v.getContext(),R.layout.putting_practice, puttDistList)); 
         s.setOnItemSelectedListener(puttDistSelectListener); 
         LinearLayout.LayoutParams sParams = new LinearLayout.LayoutParams(
           LinearLayout.LayoutParams.WRAP_CONTENT, 
           LinearLayout.LayoutParams.WRAP_CONTENT); 
         ll.addView(s,sParams); 

         layout.addView(ll); 
        } 
        alertDialog.setView(layout); 
        alertDialog.setTitle("Putting Stats - Distance to Pin"); 
        alertDialog.setNegativeButton("OK", new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialog, int which) { 
          dialog.dismiss(); 
         } 
        }); 
        alertDialog.show(); 
       } 

       break; 
     } 
    } 

    @Override 
    public void onNothingSelected(AdapterView<?> parent) { 

    } 
}; 

現在，當用戶拿起從價值對話微調s，它監聽更新與用戶輸入數據庫，但如何獲取與此微調

兩個TextView的和微調相關的包含在動態創建的線性佈局「LL」，也就是在TextView tv的textvalue父佈局「佈局」。兩者都是動態創建

在此先感謝

final AdapterView.OnItemSelectedListener puttDistSelectListener = new AdapterView.OnItemSelectedListener() { 
    @Override 
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
     //add the putt# and distance to temp_putt_stats table 
     DbAdapter adapter = new DbAdapter(view.getContext()); 
     String distValue = parent.getItemAtPosition(position).toString(); 
     switch (position){ 
      case 0: //Inches 
       break; 
      case 1: //<3ft 
       break; 
      case 2: //<6 ft 
       break; 
      case 3: //<10 ft 
       break; 
      case 4: //10-20 
       break; 
      case 5: //20-30 
       break; 
      case 6: //30-40 
       break; 
      case 7: //> 40 
       break; 
     } 
     Toast.makeText(view.getContext(), "Position :"+position+" ListItem : " +distValue ,Toast.LENGTH_SHORT).show(); 

    } 

Answer 1

對於API 17歲以上就可以生成您生成並setId()設置每個View的ID。見generateViewId和setid。

Xiaochao Yang解釋了這個問題，以及在API 17之前如何解答this Stack Overflow問題。

設置生成的ID後，可以使用findViewById()查找父佈局內的視圖。

Answer 2

您可以使用標籤。

在生成的佈局，你可以指定一個標籤（setTag（））上述（1-X），然後你可以做以下操作：

final AdapterView.OnItemSelectedListener puttDistSelectListener = new AdapterView.OnItemSelectedListener() { 
@Override 
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
    //add the putt# and distance to temp_putt_stats table 
    DbAdapter adapter = new DbAdapter(view.getContext()); 
    String distValue = parent.getItemAtPosition(position).toString(); 
    int tagNumber = (int) view.getTag(); 
    switch (tagNumber){ 
     case 0: //Inches 
      break; 
     case 1: //<3ft 
      break; 
     case 2: //<6 ft 
      break; 
     case 3: //<10 ft 
      break; 
     case 4: //10-20 
      break; 
     case 5: //20-30 
      break; 
     case 6: //30-40 
      break; 
     case 7: //> 40 
      break; 
    } 
    Toast.makeText(view.getContext(), "Position :"+position+" ListItem : " +distValue ,Toast.LENGTH_SHORT).show(); 

} 

所選項目的文本可以通過

TextView tv = (TextView) view.findViewByTag(x); 
tv.getText();
