SwichPerference에 widgetlayout 커스터마이징시 check 설정

내부적으로 android:id를 이용을 하고 있어서 따로 커스트마이징을 해서 지정을 해줘야함..귀찮음..

 

package com.example.setupproject;

import android.content.Context;
import android.preference.SwitchPreference;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Checkable;
import android.widget.CompoundButton;
import android.widget.Switch;

public class MySwitchWidget extends SwitchPreference {
 
 private final Listener mListener = new Listener(); 
 
 private class Listener implements CompoundButton.OnCheckedChangeListener {
  @Override        
  public void onCheckedChanged(
    CompoundButton buttonView, boolean isChecked) {
    if (!callChangeListener(isChecked)) {
     // Listener didn't like it, change it back.
     // CompoundButton will make sure we don't recurse.
     buttonView.setChecked(!isChecked);
     return;
    }//if             
    MySwitchWidget.this.setChecked(isChecked);
   }//    
 }//    
 public MySwitchWidget(Context context) {
  super(context); 
  init();
 }

 public MySwitchWidget(Context context, AttributeSet attrs) {
  super(context, attrs);
  init();
 }

 public MySwitchWidget(Context context, AttributeSet attrs, int defStyle) {
  super(context, attrs, defStyle);  
  init();
 }
 private void init(){
  setWidgetLayoutResource(R.layout.preference_widget_switch);  
 }

 @Override
 public void setWidgetLayoutResource(int widgetLayoutResId) {
  // TODO Auto-generated method stub
  super.setWidgetLayoutResource(widgetLayoutResId);
 }

 @Override
 protected void onBindView(View view) {
  ViewGroup viewGroup= (ViewGroup)view;
  clearListenerInViewGroup(viewGroup);
  super.onBindView(view);
  
  View checkableView = view.findViewById(R.id.pref_switch);
  if (checkableView != null && checkableView instanceof Checkable) {
   ((Checkable) checkableView).setChecked(isChecked());
   if (checkableView instanceof Switch) {
    final Switch switchView = (Switch) checkableView;
    //switchView.setAccessibilityDelegate();
    switchView.setOnCheckedChangeListener(mListener);
   }
  }
  // TODO Auto-generated method stub
  super.onBindView(view);
 }
 
 private void clearListenerInViewGroup(ViewGroup viewGroup) {
  if (null == viewGroup) {
   return;
  }
  int count = viewGroup.getChildCount();
  for(int n = 0; n < count; ++n) {
   View childView = viewGroup.getChildAt(n);
   if(childView instanceof Switch) {
    final Switch switchView = (Switch) childView;
    switchView.setOnCheckedChangeListener(null);
    return;
   }else if (childView instanceof ViewGroup){
    ViewGroup childGroup = (ViewGroup)childView;
    clearListenerInViewGroup(childGroup);     
   }//else
  }
 }
