java - IOIO，有没有办法调用 softreset();来自另一个类(class)？

Question

我有一个 fragment Activity 和一个 fragment 类；我正在尝试设置，以便当用户点击我的 fragment 类中的 Switch 时，oncheckchangedlistener 将软重置 IOIO-OTG 板，以允许用户动态地将 IOIO 上的引脚从输出更改为输入或反之反之亦然。

但是我不确定如何调用 ioio_.softReset();来自外部类的方法。

这里是一些相关的代码:

//sets the listener for the mode switches
    for(int i = 0; i<digitalIOModeSwitchArray.length;i++){
        digitalIOModeSwitchArray[i].setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // TODO Auto-generated method stub

        }
    });
}

下一步:

@Override
    protected IOIOLooper createIOIOLooper() {
        return new Looper();
    }

    public  IOIOLooper globalLooperRetriever(){
        return l1;
    }

下一步:

Answer 1

假设您的 Activity 中已经有一个循环器实例这是您需要做的

1. 定义一个接口(interface)

   public interface SoftResetListener
   {
    void softReset();
   }
   

2. 在您的 Activity 中实现该接口(interface)

   public class MainActivity implements SoftResetListener
   {
      public void softReset()
      {
         //replace with your looper instance
         looper.getIOIOBoardInstance().softReset();
      }
   
   }
   

3. 在你的 fragment 中 onCheckedChanged()

   @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)     {
       Activity looperActivity= getActivity();
   
       if(looperActivity instanceof SoftResetListener) {
         ((SoftResetListener)looperActivity).softReset();
       }
   
    }
