将togglebutton布尔值转换为整数值，然后在文本视图中加在一起

Question

我想使用四个togglebuttons（最终为8,12或16），并根据切换到的位置给每个值赋予值。

所以toggle1会给的值1或0和toggle2会给两个或零（TB4 4或0，TB8 8或0等）

我然后要添加的电流值的值所有按钮组合在一起并以文本视图显示。

我刚刚开始使用前2个，但不知道如何将这些值存入displayDecimalAnswer方法。我明显错过了一些非常明显的东西，因为听起来很简单。

帮助我Obi Wan Kenobis你是我唯一的希望。

 @Override 
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) { 
    if (compoundButton == toggle1) { 
     if (isChecked) { 
      toggle1Status = true; 
     } else { 
      toggle1Status = false; 
     } 
    } else if (compoundButton == toggle2) { 
     if (isChecked) { 
      toggle2Status = true; 
     } else { 
      toggle2Status = false; 
     } 
    } 
displayDecimalAnswer(); 
} 

    /** 
    * Displays decimal answer. 
    */ 
    public void displayDecimalAnswer() { 
     int valueOfOnes = (toggle1Status) ? 1 : 0;//Since toggle1Status is class level variable it will be accessibible 
     int valueOfTwos = (toggle2Status) ? 2 : 0; 
     int answer = valueOfOnes + valueOfTwos; 

     TextView decimalView = (TextView) findViewById(R.id.decimal); 
     decimalView.setText(""+answer); 
    }
