将 togglebutton 布尔值转换为整数值，然后在文本视图中加在一起

Question

我想使用四个切换按钮（最终是八个、十二个或十六个），并根据切换到的位置为每个切换按钮赋予一个值。

因此 toggle1 将给出一个值 1 或 0，toggle2 将给出一个值 2 或 0（tb4 4 或 0，tb8 8 或 0 等）

然后我想将所有按钮的当前值加在一起并在文本视图中显示。

我刚开始使用前 2 个值，但不确定如何将这些值输入 displayDecimalAnswer 方法。我显然在这里遗漏了一些非常明显的东西，因为它听起来很简单。

Answer 1

     @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);
    }
