@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.bifrost, menu);
    return true;
}

}

我想我可以做到这一点通过实现一个计数器，以便在每次一个复选框，将其选中会做专柜+ = 1，每次的复选框选中了它会做反 - = 1。在那之后我刚刚输入比例=（100 *计数器）/ 39。但是，由于我完全新开发Android和Java我有这个问题。我应该在哪里初始化变量计数器，我应该在哪里，然后插入计数器+ = 1等。

I was thinking I could achieve this by implementing a counter so that everytime a checkbox would be checked it would do counter += 1 and everytime the checkbox was unchecked it would do counter -= 1. After that i'd just input percentage = (100 * counter) / 39. But since I'm completely new to android developing and java I have a problem with this. Where should I initialize the variable counter and where should I then insert counter+=1 etc.

我强烈AP preciate任何形式的帮助/解释。

I'd highly appreciate any kind of help/explanation.

推荐答案

要腾出一些交通线，你可以这样来做：
在你的类仅仅指刚创建一个新的方法，即会检查每个箱子的状态：

to spare some LOCs you could do it this way: in your class jsut create a new Method, that will check the state of each box:

public static void percentageChecked(){
Vector<CheckBox> allBoxes=new Vector<CheckBox>();
CheckBox cb1,cb2, cb3;...//declare all 39 checkboxes
int counterChecked=0;

cb1=(CheckBox)findViewById(R.id.checkBox1);
cb2=(CheckBox)findViewById(R.id.checkBox2);//initialize each checkbox from the layout
...
allBoxes.add(cb1);//add each checkbox to vector
...

//iterate through all checkboxes:

for(int i=0; i<allBoxes.size();i++)
   if(allBoxes.get(i).isChecked()){
   counterChecked++;
   }
}

float percent = (counterChecked * 100.0f) / allBoxes.size();
craftedPercent.setText(percent);
}

然后为每个checkbutton覆盖OnCheckedChangeListener：

then for each checkbutton override the OnCheckedChangeListener:

cb3.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        percentageChecked();
        }
 });
