AlertDialog需要一個解決方案

我是編程新手，所以也許這個問題很愚蠢。搜索互聯網，但沒有找到。我需要這樣做，如圖所示。在一行中，添加Label和EditText。請幫幫我。AlertDialog需要一個解決方案

public void onAddExpenseClick(View viev){ 
     final String[] mChoose = getResources().getStringArray(R.array.mChoose); 
     final EditText input = new EditText(this); 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setTitle(R.string.addExpensTitle) 
       .setCancelable(false) 

      .setView(input) 
      .setPositiveButton(R.string.addExpensPB, new DialogInterface.OnClickListener() { 

      @Override 
      public void onClick(DialogInterface dialog, int which) { 
       if(input.getText().toString().equals("")) { 
        Toast.makeText(
          getApplicationContext(), 
          "Enter the correct amount", 
          Toast.LENGTH_SHORT).show(); 
        return; 
       } 
       Expense expense = new Expense(); 

       expense.setType(getTag(mChoose[itemChoosed]).toLowerCase()); 
       expense.setAmount((long)(100 * Double.valueOf(input.getText().toString()))); 
       expense.setDateAndTime(dateValue); 
       try { 
        expense.setTripId(((TravelApp)getApplication()).getTripManager().getDefaultTripId()); 
        //Log.d(LOG, expense.toString()); 
        expense.setCurrencyCode(
          ((TravelApp)getApplication()).getCurrencyManager().getEntranceCurrency() 
          ); 
        ((TravelApp)getApplication()).getExpenseManager().create(expense); 

        tabFragment.gotoGridView(); 

       } catch (SQLException e) { 
        e.printStackTrace(); 
       } 
      } 
     }) 
     .setNegativeButton(R.string.AdminDialogNB, new DialogInterface.OnClickListener() { 

      @Override 
      public void onClick(DialogInterface dialog, int which) { 
       // TODO Auto-generated method stub 

      } 
     }) 

     .setSingleChoiceItems(mChoose, -1, 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, 
          int item) { 
        itemChoosed = item; 
        } 
       }); 
     builder.show(); 

    }
