動態更新另一個微調框的微調框

Question

我有一個在運行時創建控件的框架，首先創建一個微調框，然後是第二個，第二個微調框的細節取決於第一個選擇。 因爲我可以更新第二個微調的數據取決於第一個？

 final Spinner Combo2 = new Spinner(FichaRutasVerif2SeccionSlideFragment.this.getActivity()); 
         final Spinner Combo1 = new Spinner(FichaRutasVerif2SeccionSlideFragment.this.getActivity()); 

         List<String> list = new ArrayList<String>(); 
         list.add("TERRESTRE"); 
         list.add("FLUVIAL"); 
         list.add("AEREO"); 
         final ArrayAdapter<String> adapterCombo = new ArrayAdapter<String>(FichaRutasVerif2SeccionSlideFragment.this.getActivity() 
           ,android.R.layout.simple_spinner_item,list); 
         List<String> list2 = new ArrayList<String>(); 
         list2.add("OP1"); 
         list2.add("OP2"); 
         final ArrayAdapter<String> adapterCombo2 = new ArrayAdapter<String>(FichaRutasVerif2SeccionSlideFragment.this.getActivity() 
           ,android.R.layout.simple_spinner_item, list2); 

         if(listFormato.get(posicion).cSeccion.trim().equals("M")) 
         { 
          adapterCombo.setDropDownViewResource(R.layout.spinner); 
          Combo1.setAdapter(adapterCombo); 
          Combo1.setSelection(listFormato.get(posicion).iIndexCombo); 
          llTempZZ.addView(Combo1); 
          Combo1.setGravity(Gravity.CENTER); 
          llTempXX.addView(llTempZZ); 
          llTEMPADRE.addView(llTempXX); 
          pllh.addView(llTEMPADRE); 

         } 

         else if(listFormato.get(posicion).cSeccion.trim().equals("U")){ 
          final Spinner Combo0 = new Spinner(FichaRutasVerif2SeccionSlideFragment.this.getActivity()); 
          List<String> list3 =new ArrayList<String>();

          adapterCombo3.setDropDownViewResource(R.layout.spinner); 
          Combo0.setAdapter(adapterCombo3); 
          llTempZZ.addView(Combo0); 
          llTempXX.addView(llTempZZ); 
          //llTempXX.addView(llTempAA); 
          llTEMPADRE.addView(llTempXX);

          Combo0.setOnItemSelectedListener(new OnItemSelectedListener() { 
           public void onItemSelected(AdapterView<?> adapterView, 
                  View view, int pos, long id) {

            RECORDCARDITEM_DAO.Actualizar(FichaRutasVerif2SeccionSlideFragment.this.getActivity(), listFormato.get(posicion)); 
           } 
           public void onNothingSelected(AdapterView<?> arg0) { 
            // TODO Auto-generated method stub 
           } 
          }); 



         } 
         else if(listFormato.get(posicion).cSeccion.trim().equals("T")) 
         { 
          adapterCombo2.setDropDownViewResource(R.layout.spinner);

         } 

Answer 1

你可以做這樣的事情

Spinner firstSpinner = (Spinner) findViewById(R.id.first_spinner); 
// You can set your first spinner values here if not set already, and then 
firstSpinner.setOnItemSelectedListener(onFirstSpinnerChange(firstSpinner)); 

而進一步增加本

AdapterView.OnItemSelectedListener onFirstSpinnerChange(Spinner mySpinner) { 
    return new AdapterView.OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
      // You can add this method to set the values of the second spinner in your activity 
      // You can use the position, or alternatively selectedItemView for this purpose to identify the selected item 
      setSecondSpinnerBasedOnFirstOnePositionSelected(); 

      // Or you can just set your spinner in this block 
     } 

     @Override 
     public void onNothingSelected(AdapterView<?> parentView) { 
      // do nothing 
     } 
    }; 
}
