onresume

is it ok in an activity's procedure to force the onResume event by calling this.OnResume() ? Or should I implement another procedure that's called by both OnResume and by the first member ? Implement another procedure that's called in your override of onResume() . The latter is not intended to be called by you, it's a convenience method that tidies up or readies the activity when its state changes to resume . A lot like onCreate() through to onDestroy() . What @SK9 said, but also especially because you must call super.onResume() when you override the onResume method, so you're not in control

I am using fragments in my application.I have a fragment that contains EditText and some Dialogfragment . When i click one particular widget it will move to next fragment. I need the first fragment in the backstack,so i added addToBackStack method also. The second fragment doesn't contain any EditText . Now the problem is, when we touch or press the second fragment, EditText in the first fragment get the focus and the dialogs are coming. I got the following code getView().setFocusableInTouchMode(true); getView().requestFocus(); I placed this in onResume() . But onResume() will not be called

I'm have a game that's uses SurfaceView implementation to display the objects. I have a thread which draws the SurfaceView time-to-time to the screen. The game is running completely. Unfortunately, it needed to have a pause function whenever the game is interrupted. Well, I know that I need to manipulate onResume and onPause . But I can't get it right. The error points me back to surfaceCreated where I start the thread telling me that the thread has started already. I tried using the resume and suspend on the onResume and onPause respectively but nothing changed. How can I achieve this? I have

I have a problem. After initializing the camera for a preview and bringing another app into focus, then back to my app: the preview shows up black. If I continue to take a picture, it takes a picture of where I point the camera normally. Am I doing something wrong on the OnResume() override? Relative code is below: public void ReleaseCamera() { if (myCamera != null) { myCamera.Release(); myCamera = null; } } protected override void OnPause() { base.OnPause(); if (myButtonState == ButtonState.CameraActive) ReleaseCamera(); } protected override void OnResume() { base.OnResume(); if

I was wondering what could be the reason for not having a callback at the application level when an application goes to background and comes to the foreground. Activity class's onPause and onResume are only called on the current top activity. If I want to stop some background task that has the application level scope, then there is no easy way I can stop it when the app goes to background. There is high demand for these event callbacks. Why doesn't Android have a app level callback on pause and resume of applications? Can it be implemented in Android at the task(activity stack) level if not at

How can I reload SharedPreferences when I resume from one activity to another? If I resume, it is possible that user has changed the settings. Is it possible to reload SharedPreferences or do I need to refresh/reload activity. And if, then how? There is no difference in how you get and set SharedPreferences normally and from doing so in onResume . What you will need to do in addition to getting the most recent preferences, is update any objects you have in the Activity that use preference values. This will ensure your Activity is working with the most recent values. A simple example: protected
