问题 I'm stuck with a pretty simple issue: I'm trying to build a Preference screen in my app and I'd like to do it with the new, now-standard PreferenceFragment method. This is my prefs xml: <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:title="@string/prefs_interface_settings"> <SwitchPreference android:key="show_average" android:title="Show average length of work day" android:defaultValue="false" android:summary="Display the calculated

TabActivity with ActivityGroup and PreferenceActivity child

由 心不动则不痛 提交于 2019-12-08 03:25:44
问题 I have a TabActivity where each tab has ActivityGroup. On the home ActivityChild of the first group I have an menu option, which gives to the user the option to open preferences. When I click "Preferences" on menu, I start PreferenceActivity inside ActivityGroup, which shows PreferenceActivity on the first tab. The problem is when I click on any specific preference which has to show a Dialog (for EditTextPreference). I have the following exception: android.view.WindowManager$BadTokenException

EditTextPreference.setText(value) not updating as expected

由 允我心安 提交于 2019-12-07 17:33:41
问题 I'm trying to prevent the user from entering an empty string into an EditTextPreference (in the example, catName ). I use a OnPreferenceChangeListener to detect when a change is made to the EditTextPreference , and if there is a change and the string is blank, I use the EditTextPreference.setText() command to reset to the old value. However, the new value doesn't show up properly if I reopen the EditTextPreference in the GUI (the string is blank), and if I go back into the main app, I can

Is possible to change the summary of EditTextPreference dynamically in Android?

由 隐身守侯 提交于 2019-12-07 07:32:51
问题 I set up a preferenceScreen to edit the settings in my application. I would like to insert an EditTextPreference that contains a Title like "set your name" and a summary containing the name entered. Is that possible? thank you in advance! 回答1: Sure, here is a short example: EditTextPreference etp = (EditTextPreference) findPreference("the_pref_key"); etp.setSummary("New summary"); This requires that you display your preferences either from a PreferenceActivity or from a PreferenceFragment ,

自定义带有图片的PreferenceActivity

次和大家分享一下关于 android 中 PreferenceActivity 使用以及为配置信息文件中添加图标的功能，首先给大家看一下效果图： 大家可以看到这是最终的效果图， android 提供了很大的空间供开发者可以自行定义控件，你想让你的控件长成什么样子，你就可以让它长成什么样子。自己也很推崇这类开发思想，因为自行定义控件（前提：系统内置的控件满足不了自己的需求）的优点不言而喻。这边主要分享两种类型： 1: 单纯标题类型； 2: 带有复选框。 先和大家介绍一下 PreferenceActivity 的几种标签： 系统提供的这些标签默认都是没有图片信息 Preference ：没有图片单纯的文字 EditTextPreperence ：带有编辑框 ListPreference ：一个 List 集合，右边会有一个较小的向下的三角形 RingtonePreference ：铃声的相关设置 其中上面的标签当中，都有 android:key 和 android:title 两个属性，如果你直接使系统内置的这些标签，其中没有任何的扩展，在通过 SharedPreferences 的时候对应的 key 便是 android:key 中的 key ，在你的应用中需要取值的时候也通过这个 key 来取，数据也不用开发者通过代码保存，系统自动就会保存您在设置中改变的数据。 Android
