android - 获取复选框的首选项以在单独的活动中显示视图

Question

所以几乎我有一个带有复选框的 sharedPreferences 设置，当该框被选中时，它会创建一个动态 ImageButton。我的问题是，当我检查它时，它似乎没有问题，但是当我取消它时，它仍然存在？

我的源代码：

package org.iimed.www;    

import java.util.ArrayList;

import android.R.string;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.app.Activity;

import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

import android.view.View;  

import android.widget.Button;
import android.widget.CheckBox;
import android.widget.ImageButton;
import android.widget.RelativeLayout;
import android.widget.Toast;


import android.view.View.OnClickListener;
public class Sundayopen extends Activity implements OnClickListener {  

int i = 0;    

public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.sundayopen);
        super.onResume();
        RelativeLayout    ll = (RelativeLayout)findViewById(R.id.sundayopen);
        ImageButton ab = new ImageButton(this);
        SharedPreferences prefs = PreferenceManager
                .getDefaultSharedPreferences(this);{



                  if(prefs.getBoolean("checkBox",true)) {
                      ll.addView(ab);
                      ab.setImageResource(R.drawable.adaba);
                      ab.setOnClickListener(this);
                      ab.setBackgroundColor(View.GONE);
                      }else{
                if(prefs.getBoolean("checkbox", false)){
                    ll.removeView(ab);

                }}}}

    // TODO Auto-generated method stub

                @Override
                protected void onPause(){
                    super.onPause();
                      RelativeLayout    ll = (RelativeLayout)findViewById(R.id.sundayopen);
                        ImageButton ab = new ImageButton(this);
                    SharedPreferences prefs = PreferenceManager
                            .getDefaultSharedPreferences(this);{ 

                              if(prefs.getBoolean("checkbox", true)) {
                                  ll.addView(ab);
                                  ab.setImageResource(R.drawable.adaba);
                                  ab.setOnClickListener(this);
                                  ab.setBackgroundColor(View.GONE);
                                  }else{

                            }}}
                }

取消选中时，检查是否在共享首选项中将复选框值设置为false。
