为什么这个开关盒没有开火？

Question

我有一整行的开关案例与oncheckboxclickeds相关联，我用它来总计一个数字。

该行中的每个案例都工作得很漂亮，除了最后一个案例，似乎根本没有做任何事情，我无法弄明白为什么。

这很好，直到最后：

package com.example.blazingboltcalculator;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.CheckBox;
import android.widget.TextView;


public class MainActivity extends Activity {



int attack=11;
int damage=3;
int flankAttack;
int pbs;
int justice;
int destruction;
int bane;
int DF;
int GMW;
int heroism;
int deadly;
int attackTotal;
int damageTotal;

String flames="";
String baneDice="";
String keen="";
String diceTotal;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

我对编程很陌生，有没有人知道可能会搞砸作品？除了最后一个案例之外，整个混乱都是完美的。

好吧，我们需要更多信息来帮助您。但是，我假设您正在尝试使用主要活动实施的OnCheckedChangeListener？如果您在引用ID时遇到问题，您可以随时在特定元素上实现单独的lisenter，例如：

checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener()
   {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
        {
            if ( isChecked )
            {

                prevChecked = true;
        Log.d("CHECKBOX","Previously Checked = "+prevChecked);
            }else{

                prevChecked = false;
        Log.d("CHECKBOX","Previously Checked = "+prevChecked);

            }

        }
    });

prevChecked是全局变量。我还抛出了几个Log，因此您可以将信息输出到LogCat。希望这有助于您的调试。

** * ** 编辑以适应您添加的评论 * < / EM> ** * ** * ** * ***

您是否尝试使用if语句交换switch语句。 e.g。

if(v.getId() == R.id.checkbox1){

}else if(v.getId() == R.id.checkbox2){

}

此外，什么接口onCheckboxClicked(View v)，这是一个自定义元素？你是如何在R.layout.activity_main.xml中定义复选框的？如果你有一个复选框界面，你需要像我上面的例子那样实现一个监听器。我无法看到你在任何地方设置听众，也没有在你的活动中实现它。例如：

public class MainActivity extends Activity implements onCheckChangedListener {

但据我所知，除非它是一个自定义元素，否则public void onCheckboxClicked(View v)甚至被调用都没有任何意义。这example可能会有所帮助。
