如何将共享首选项应用于复选框

Question

我是Android开发的新手，我创建了一个复选框以及如何使用共享首选项保存选中/取消选中

final Button add = (Button) findViewById(R.id.add);
        add.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                addNewBubble();
                add.setEnabled(false);
            }
        });

        CheckBox checkBox = (CheckBox)findViewById(R.id.add_fb);
        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                isCheckedValue = isChecked;

            }
        });

    }


private void addNewBubble() {
        BubbleLayout bubbleView = (BubbleLayout)LayoutInflater.from(MainActivity.this).inflate(R.layout.bubble_layout, null);
        bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() {
            @Override
            public void onBubbleRemoved(BubbleLayout bubble) {
                finish();
                System.exit(0);



            }
        });
        bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() {

            @Override
            public void onBubbleClick(BubbleLayout bubble) {
                Intent in = new Intent(MainActivity.this, PopUpWindow.class);
                in.putExtra("yourBoolName", isCheckedValue );
                startActivity(in);

            }
        });
        bubbleView.setShouldStickToWall(true);
        bubblesManager.addBubble(bubbleView, 60, 20);
    }

有这码两个复选框add和add_fb我想使应用程序记住，如果该复选框被选中或取消选中

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final CheckBox checkBox = (CheckBox)findViewById(R.id.checkBox);
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        final SharedPreferences.Editor editor = preferences.edit();
        if(preferences.contains("checked") && preferences.getBoolean("checked",false) == true) {
           checkBox.setChecked(true);
        }else {
            checkBox.setChecked(false);

        }
        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                if(checkBox.isChecked()) {
                    editor.putBoolean("checked", true);
                    editor.apply();
                }else{
                    editor.putBoolean("checked", false);
                    editor.apply();
                }
            }
        });
    }
