英文:
Is it bad leaving SharedPreferences & Editor open
问题
例如，你有这个类
private SharedPreferences sp
private SharedPreferences.Editor editor
protected void onCreate(..) {
this.sp = ...
this.editor = this.sp.edit();
}
这样做有问题吗？
英文:
e.g. you have this class
private SharedPreferences sp
private SharedPreferences.Editor editor
protected void onCreate(..) {
this.sp = ...
this.editor = this.sp.edit();
}
Is it bad to do that?

共享偏好设置是正常的，但编辑器不行。
只要您不调用编辑器的 commit 或 apply 方法，值就不会被写入 preferences.file，我认为在从 sp 中读取时也不会获取到这些值。
所以作为一种习惯，写入偏好设置值时始终这样做（Java）
sp.edit().putString(key, value).apply()
或者使用 putInt、putBoolean 等方法。
英文:
The shared preferences are ok, the editor isn't.
As long as you do not call editor's commit or apply, the values are not written to the preferences.file and I think you also will not get the values when reading from sp.
So as a habit, always do this when writing a preference value (Java)
sp.edit().putString(key, value).apply()
Or putInt, putBoolean etc.
