lifecycle

I have a litle doubt. I have an activity that have 3 fragment inside. I need to restart the state of one of these fragments. Restart only one . Old, but may be useful to someone else. To refresh the fragment, you need to detach the fragment and reattach it Fragment frg = null; frg = getFragmentManager().findFragmentByTag("Your_Fragment_TAG"); final FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.detach(frg); ft.attach(frg); ft.commit(); Your_Fragment_TAG is the name you gave your fragment when you created it 来源： https://stackoverflow.com/questions/13989300/restart-fragment

If I correctly combined the information contained in BalusC's great 2006 post http://balusc.blogspot.ch/2006/09/debug-jsf-lifecycle.html with Optimus Prime's even earlier post http://cagataycivici.wordpress.com/2005/12/28/jsf_component_s_value_local/ I get the following: My understanding: During the APPLY_REQUEST_VALUES phase, the input value is set to a submittedValue property of the UI component (e.g. inputComponent. setSubmittedValue ("test")). During the PROCESS_VALIDATIONS phase, the same values are read from the submittedValue property (presumably inputComponent. getSubmittedValue ())

I just introduced a bug into my code because I seem to have misunderstood the jsp tag lifecycle. The tag worked like this before the bug: I pass the tag some collection as an attribute, and it displays it as a table. The collection was passed into the JSP from the controller. After the bug: I removed the attribute which set the collection. Instead, in the tag I check if the collection is null, and then grab it by name from the request (using a naming convention). The thing that I didn't expect: after the collection was initially set in the tag, it would never become null on subsequent

I am trying to create a custom time picker. But the problem that ran into is that when i rotate the screen. also if I press the home button to leave the app it crashes when i come back with the same error. public class MyTimePicker extends RelativeLayout { private NumberPicker hour; private NumberPicker minute; private NumberPicker am; private int interval = 5; public MyTimePicker(Context context) { super(context); init();} public MyTimePicker(Context context, AttributeSet attrs) { super(context, attrs); init();} public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr) {

I can't find the Application's object (extend Application) life cycle. For example, what happens if I have a broadcast receiver which is called through Alarm. Will methods in Application being called? Or is everything independent from the Application? If I have a datahelper instantiated in the Application and I call it from broadcast receiver, will it available? Which is the Application object life cycle, when it is destroyed? when is it called when using Alarms? What happens when the activity is not in foreground with the Application object? Thanks in advance. Guillermo. Look at it this way:

I’m using Eclipse Kepler on Mac 10.9.5. I have imported a number of Maven projects using the m2e Eclipse plugin. All these projects are children of a parent pom. When I look at the “Overview” in the individual child pom.xml files, I see stuff like this: Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:write-project-properties (execution: default, phase: process-resources) I would like Eclipse to execute these lifecycle phases at the appropriate times, but I’m not sure how to do that. When I select Eclipse’s suggestion … Permanently
