android sharedpreferences set value
提问by davs
I have preferences page. It has field 'Show info screen' (as checkbox).
我有偏好页面。它具有“显示信息屏幕”字段(作为复选框)。
I have also info page which also should have checkbox 'Show me again'.
我还有信息页面,其中也应该有复选框“再次显示”。
As I've understand, I can get value from preferences page via PreferencesManager.getDefaultPreferences(context)
...
据我了解,我可以通过以下PreferencesManager.getDefaultPreferences(context)
方式从偏好页面中获取价值...
But how I should set preferences value for the checkbox on info page?
但是我应该如何为信息页面上的复选框设置首选项值?
I tried to use context.getSharedPreferences(PREF_NAME, 0).edit()
, to set value but it doesn't correlate with PreferencesManager's corresponding value.
我尝试使用context.getSharedPreferences(PREF_NAME, 0).edit()
, 来设置值,但它与 PreferencesManager 的相应值无关。

It depends on whether you are after one set of preferences for your application, or one set per activity.
这取决于您是在为应用程序设置一组首选项,还是为每个活动设置一组首选项。
I've used code like this:
我使用过这样的代码:
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getContext());
Editor editor = prefs.edit();
editor.putBoolean(PREF_NAME, false);
editor.commit();
and
和
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getContext());
if (prefs.getBoolean(PREF_NAME, true)) {
// etc
}
