自定义首选项跳过屏幕

我写了一个自定义首选项类，其中包含一个简单的进度栏，以允许设置音量等。 偏好效果很好，直到我尝试将这两个偏好设置放入我的首选项屏幕中。自定义首选项跳过屏幕

当我这样做时，首选项屏幕开始变得很粗糙»当我拖动搜索栏时，两个自定义首选项会不断切换位置。

任何人有任何想法为什么发生这种情况？ 感谢

编辑： 这里是习俗偏好的代码

     return value; } 
    private void updatePreference(int newValue)  { 
     SharedPreferences.Editor editor = getEditor();  editor.putInt(getKey(), newValue);  editor.commit(); } 
} 

编辑：我发现，创造与excat相同的代码，但不同名称的第二类每一个使用一个解决问题=有史以来最糟糕的一次。我不想这样做。任何人有任何想法？
