获取android中选择的偏好值
有没有办法获取列表首选项新选择的值。我尝试使用 onClick 和 onChange 方法获取值，但它们都返回以前的值。据我所知，内部状态是在调用此方法后设置的。有什么方法可以获取列表首选项的当前选定值，以便我可以将该值传递给绑定服务来重新安排计时器。请帮助我...
这是我使用的代码：
Preference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
// TODO Auto-generated method stub
Context c = getApplicationContext();
SharedPreferences sp = preference.getSharedPreferences();
String period = sp.getString("prefKey", "defValue");
return true;
}
});
Is there any way to get the newly selected value for a list preference. I have tried to get the values using onClick and onChange methods, but both of them returning the previous value. I understand that the internal state is set after calling this method. Is there any way to get the current selected value for a list preference so that I can pass the value to a binded service to reschedule a timer. Please help me ...
Here s the code I used:
Preference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
// TODO Auto-generated method stub
Context c = getApplicationContext();
SharedPreferences sp = preference.getSharedPreferences();
String period = sp.getString("prefKey", "defValue");
return true;
}
});

经过重新检查方法后，我终于得到了自己的答案。
侦听器方法中有一个名为“newValue”的对象。顾名思义，它是选择的新值:)
Finally I have got the answer my self after rechecking the method.
There is an object called 'newValue' in the listener method. As the name says, its the new value selected :)
