Hiding app title bar in Android pager

阅读更多关于 Hiding app title bar in Android pager

问题 Can anyone tell how to hide the app title bar in Pager fragment. 回答1: This should be enough: ActionBar bar = getActionBar(); // you might need to use getSupportActionBar() based on your project setup bar.setDisplayShowTitleEnabled(false); bar.setDisplayShowHomeEnabled(false); 回答2: Warren is correct. And if you want to hide it in your theme, you can do it by inheriting from a theme that does not display it: For pre-Honeycomb styles: <style name="HiddenActionBar" parent="@android:style/Theme">

how to replace one full-screen dialog fragment with another without showing parent activity?

阅读更多关于 how to replace one full-screen dialog fragment with another without showing parent activity?

问题 I have an Activity that uses a single custom DialogFragment class. Its appearance is data driven, so it can look fairly different from invocation to invocation. It is "full screen", i.e. setStyle(DialogFragment.STYLE_NO_FRAME, android.R.style.Theme); In response to the result of a network call I dismiss() the currently showing instance (if there is one) and show() a new one: final CustomDialogFragment dialog = (CustomDialogFragment) getSupportFragmentManager().findFragmentByTag(DIALOG_TAG

FragmentPagerAdapter not restoring fragments upon Orientation Change

阅读更多关于 FragmentPagerAdapter not restoring fragments upon Orientation Change

问题 EDIT: I found out that the Activity is saving the instance, but the Fragments saved data is not making it up to the Activity savedInstanceState. I'm saving the current time in the outState, but its not making its way all the way up, as the activity has nothing in its SavedInstanceState for the time and returns 'null' for the time if I print it to the logcat.... I am building an application that has the a countup and countdown timer built in. The basic hosting activity for the timers is a

How do I get the back button to go to a certain Fragment in horizontal scrolling? Exits app right now

阅读更多关于 How do I get the back button to go to a certain Fragment in horizontal scrolling? Exits app right now

the title pretty much explains it. I have horizontal scrolling set up, the first screen has buttons to the other Fragments as well as the whole horizontal scroll system. What I would like is for the user to be able to press the back button when on one of these fragments and for the app to return to the first screen with all the buttons. From there I want the back button to be an AlertDialog asking the user if they would like to exit the app. At the moment this is what is happening (On all Fragments when you press the back button the AlertDialog I created pops up). I've looked into Fragment
