android Preference 怎么设置selector
1、在res/drawable目录下新建一个xml文件，名字叫selector_example.xml，里面写入如下代码：
2、在res/values目录下新建一个xml文件，名字叫attrs.xml，里面写入如下代码：
3、在res/xml目录下新建一个xml文件，名字叫preferences.xml，里面写入如下代码：
4、在应用程序代码中，添加如下代码：
PreferenceManager manager = getPreferenceManager(); manager.setSharedPreferencesName("preferences"); addPreferencesFromResource(R.xml.preferences);5、运行程序，就可以看到你设置的selector了。

android Preference 怎么设置selector，用code
实现
//设置Seletor
ListPreference listPreference = (ListPreference)findPreference("list_preference_key");
listPreference.setEntries(R.array.list_preference_entries);
listPreference.setEntryValues(R.array.list_preference_entry_values);
listPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
//TODO
return true;
}
}); -
jiayu.lin说:
android ListPreference 怎么设置selector，用code
可以使用ListPreference的setEntries和setEntryValues方法来设置selector：
ListPreference listPreference = (ListPreference) findPreference("list_preference");
String[] entries = new String[] {"Option 1", "Option 2", "Option 3"};
String[] entryValues = new String[] {"1", "2", "3"};listPreference.setEntries(entries);
listPreference.setEntryValues(entryValues); -
