using an Activity as preference activity?

Question

Is it possible to use a normal Activity as a preference Activity ?

I know you can do this with preference Activity , but what i am trying to do is make a layout which contains a CheckBox , Buttons , and/or a ListView . So basically a normal layout in xml.

But is it possible to have those items be preferences sort of like they do in a preference screen? So overall i am trying to make a preferences in an Activity from a layout.

Answer 1

If you read the documentation you would have found: PreferenceActivity with this available you have NO reason to use a Activity. While this is still doable, its not recommended, use what is available.

Answer 2

Yes, it is possible. you can directly read and write values from preference xml without preference activity

For reading preference xml values, you can use code like given below

int value = this.getSharedPreferences("PreferenceFileName", MODE_PRIVATE).getInt("PreferenceName", 1);

to write value to preference xml value, use some thing similar to this

Editor e = this.getSharedPreferences("PreferenceFileName", Context.MODE_PRIVATE).edit();
e.putInt("PreferenceName", newvalue  );
e.commit();

you need to read the values when activity is shown and save it when leaving activity. But if you are looking for easiest way to save preference then use preference activity.
