使用带有复选框的SharedPreferences并在一个活动和一个片段之间切换

Question

所以，由于Displaymetrics，我有一个显示为 Popup 的活动，其中我有几个 CheckBoxes （checkBox1，checkBox2等）。

我希望在离开此活动时保存 已检查或未检查状态（以及部署更多操作：播放声音，附加字符串等），我这样做使用 SharedPreferences 。

到目前为止，工作代码

        final checkBox1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (checkBox1.isChecked()) {
                buttonSound.start();
            } else {
                buttonSound.start();
            }
            SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); // 0 - for private mode
            SharedPreferences.Editor editor = pref.edit();
            editor.putBoolean("checkbox", checkBox1.isChecked());
            editor.commit();
            if (pref.getBoolean("checkbox", false) == true){
                checkBox1.setChecked(true);
            } else{
                checkBox1.setChecked(false);
            }
        }
    });

    final CheckBox checkBox2 = (CheckBox) findViewById(R.id.checkBox2);
    checkBox2.setChecked(false);

    checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (checkBox2.isChecked()) {
                buttonSound.start();
            } else {
                buttonSound.start();
            }

            SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); // 0 - for private mode
            SharedPreferences.Editor editor = pref.edit();
            editor.putBoolean("checkbox", checkBox2.isChecked());
            editor.commit();
            if (pref.getBoolean("checkbox", false) == true){
                checkBox2.setChecked(true);
            } else{
                checkBox2.setChecked(false);
            }
        }
    }

只是完美！

然后，我在我的实际项目中上传了相同的代码，其中 Fragment 启动了checkBoxes所在的Popup活动。

BUT

当我在弹出区域外单击时（是的，我在前一个项目中也通过处理活动的样式做到了，这很好）并且我重新进入Popup活动，我看到状态不是已经保存了！

这两个这些项目都有相同的样式，复选框的ID，元素等等，它是纯粹的复制和粘贴，我认为这是活动的原因弹出活动之前是片段。

简而言之：片段 - ＆gt;点击---＆gt;打开弹出活动---＆gt;我标记任何一个复选框 - ＆gt;我点击外面或按回物理设备 - ＆gt;我重新打开我不再检查弹出活动和我选中的复选框。

为什么这样？片段有什么变化，我应该如何调整我的代码？

编辑：

这是POPUP活动的原始代码

公共类Popup1扩展了Activity {

    DisplayMetrics dm = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(dm);

    int width = dm.widthPixels;
