Android Settings UI -

Android Settings UI -

i looking build similar settings ui of scheme android. want few checkboxpreferences, switchpreferences, edittextpreferences on launch of application , when user selects 1 preference open fragment not able figure out.

i have referred settings guide insists on using preference header. while displaying headers there unlikely overhead facing of displaying texts in turn load fragments.

for example,

my preference header :

<preference-headers xmlns:android="http://schemas.android.com/apk/res/android" > <!-- these settings headers used on tablets. --> <header android:fragment="${packagename}.${activityclass}$generalpreferencefragment" android:title="@string/pref_header_general" /> <header android:fragment="${packagename}.${activityclass}$notificationpreferencefragment" android:title="@string/pref_header_notifications" /> <header android:fragment="${packagename}.${activityclass}$datasyncpreferencefragment" android:title="@string/pref_header_data_sync" /> </preference-headers>

and load actual data, having utilize it. actual info have checkboxes , edittexts.

it great if gave insights on this. of great help if launch actual fragment info on loading of screen. improve if have command of fragment phone call , phone call other fragments when fragment item selected.

to create custom preference headers, switches , such, need extend preferenceactivity headers android docs describe , override preferenceactivity.setlistadapter create own list adapter, creates custom views. made pastebin code actual android settings activity help out. http://pastebin.com/rhsndgcq
