如何在Android应用程序中为CustomAutoCompleteTextView实现setOnFocusChangeListener

Question

 actvDivName.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
               try{
                   String str = actvDivName.getText().toString();
                   if(b){
                       actvPType.setText("");
                   }

                   else{
                       for (int i=0;i<QRDivArrayAdapter.getCount();i++)
                       {
                           String temp = QRDivArrayAdapter.getItem(i).toString();
                           if (str.compareTo(temp) == 0){
                               return;
                           }
                       }
                       actvDivName.setText("");
                   }
            }catch(Exception focusfordivision)
               {
                   Log.d("eEmp/Resume", "Error raised due to " + focusfordivision.toString());
               }
        }
        });


     actvEntryCategory.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean b) {
                String str = actvEntryCategory.getText().toString();
                if(b)
                {
                    actvDivName.setText("");
                    actvPType.setText("");
                }
                else
                {
                    for (int i=0;i<EntryTypeAdapter.getCount();i++)
                    {
                        String temp = EntryTypeAdapter.getItem(i).toString();
                        if (str.compareTo(temp) == 0){
                            return;
                        }
                    }
                    actvEntryCategory.setText("");
                }

               // actvEntryCategory.setError("Please select valid Entry Type");
            }
        });

actventry，actventryDivName，actvProductType在xml文件中有三个CustomAutoCompleteTextViews。

该方法适用于actventry但不适用于actventryDivName和actvProductType。

actvDivName和actvEntryCategory是CustomAutoCompleteTextViews。同样，我也写了这个方法来保留一个CustomAutoCompleteTextView。

我的布局中有三个CustomAutoCompleteTextView，但此方法仅针对第一个CustomAutoCompleteTextView调用，而不是针对其余两个调用。

我犯了什么错误？我是android的新手。
