1.首先定义一个回调接口

 //状态回调接口
 public interface OnStateChangeListener{
    void onStateChange(boolean currentState);
 }

2.拿到回调接口的对象

 private OnStateChangeListener mOnStateChangeListener;//回调接口对象
 public void setOnStateChangeListener(OnStateChangeListener listener){
     this.mOnStateChangeListener = listener;
 }

3.调用回调方法，将状态传递出去

mOnStateChangeListener. onStateChange(true/false);

调用时：
togglebutton 为 回调接口类的对象

togglebutton.setOnStateChangeListener(new OnStateChangeListener() {                     
@Override           
public void onStateChange(boolean currentState) {               
    if(currentState){//打开状态                 
           Toast.makeText(getApplicationContext(), "开关打开", 0).show();       
   }else{//关闭状态                 
           Toast.makeText(getApplicationContext(), "开关关闭", 0).show();       }           
 }      
});
