I would like to show the preference value in the summary field. This accepted answer shows how to do it for a ListPreference.
Is there a similar way to do it for an EditTextPrefernce in the layout instead of extending the class?
I just have a little method that updates the preference summary every time a preference changes. I found this somewhere online back when I needed it but unfortunately I don't remember where to credit :(
Edit: Nevermind, I found the source.

So I'm new to Android development and I'm currently figuring out TextWatcher.
What I'm attempting to do is attach my TextWatcher listener to an EditText widget and after the user has put in some text, say "Hello" and he highlights "llo" and types in r, I display the change in a TextView widget. For the above example it will display "llo --> r".
Now from what I've read and tried, since the textchangelistener is called every time the user types in something, my code ended up crashing when I ran it on my phone.
Is there a way to call the listener only when the highlighted text is changed so as to avoid calling it every time I'm just typing something in the EditText widget? I hope my question makes sense, I've tried looking around before posting here but I couldn't find anything.
Not looking for code, just some pointers so I can figure out how to do this.
Thanks!
Your best bet would be to use a OnEditorActionListener instead of a textwatcher which I didnt know existed until now. It gets called when there is a change to a textview, and since edit text is a textview than it will work perfectly.
Heres some info on the listener
Btw welcome to the android platform, I think you'll find that it is a rich language and definitely worth learning. If you really want some pointers your main point of reference should be this link which has many guidelines and pointers in the develop tab. Good luck
I have no idea how to achieve this, and don't know if it's achievable or not.
I have a sharedPreference value I set via my android app like this
menu button -> settings -> listPreference (a 1 digit value is set this way, among 3 values!!!)
I would however like to be able to set this value without entering the settings menu first, because it is changed often. Im thinking a button should take me directly to the listPreference dialog box like this!
Button -> listPreference
Is is possible to omit the settings menu like this?
Thanks
I asked somthing similar some time back. There is no quick solution but I have a coded up custom solution in the answer to this question
I have added a SeekBar control to the preference by java code. It's got added and shown up in the preference. I also added a EditTextPreference and a checkbox to the preference. Now I dragged up the seekbar to some value. After this if I select checkbox the seekbar gets reset to initial value ( I meant to say the selected seekbar value not staying ...it is going back...).
Do you please guide me what went wrong?
What I think you may need to do is implement OnSeekBarChanged and add an onProgressChanged function to your code, then have it reset the seekbar preference to the current value. Since you didn't include any code, nor did you specify, I don't know if you ever tried to reset the value. If you didn't, it makes sense that the seekbar would set itself back to the preference value. Hope that helps a bit.
I found where the problem is. Actually OnCreateView method of the custom preference gets called whenever the checkboxpreference or edittextpreference been edited. I am just resetting the SeekBar value from sharedpreferences saved values in onCreateView method of my custom preference. That fixed my problem. And thanks to all for there replies.
I am using preferences, and this snippet of XML always causes my application to stop unexpectly when I hit a menu settings button which is supposed to display a list of preferences. I can use CheckBoxPreference and ListPreference successfully but I cannot use DialogPreference. I cannot seem to find an example XML snippet anywhere.
I need this dialog to collect a phone number in a string.
I should have been using EditTextPreference which extends DialogPreference. This works.
i am using a listprefernce in my app and when a user makes a selection I would like to check it for errors, but when i set an onclicklistener it starts when i select the listpreference, not when i make my selection. is there a way to make it check the selection right after they make it?
found the answer. incase anyone else wants to know you need to use setOnPreferenceChangeListener and use the newValue object.
