Retrieve an activity after Time out warning notification

由 送分小仙女□ 提交于 2019-12-18 07:08:39
问题 I'm trying to implement time out notification. Here is what I want to do. If app goes to the background mood, after 5 minutes it should warn the user that app will be signed out. After this notification, if user opens the app, it should ask for the password, if user inputs correct pass, it should retrieve the screen that he left 5 mins ago. My problem is that I cannot save the activity that user left in order to retrieve after they input password. Here is what I've done so far: I added a

ListView doesn't visually update its content after notifyDataSetChanged

由 旧城冷巷雨未停 提交于 2019-12-10 18:38:20
问题 I have a static array of items which is set to a listview, that I might modify from another Activity (add some more items to it). So when I turn back to first activity, I have to refresh the content of the listview with the new items. I do that by: adapter.notifyDataSetChanged() in the onStart() method, verifying of course if I have to do so. Problem is, I only see my listview changed only if I scroll the list a bit. What could the problem be? LE: Solution was to set listview.invalidateViews(

Android lifecycle: Fill in data in activity in onStart() or onResume()?

由 陌路散爱 提交于 2019-12-08 17:40:22
问题 Should you get data via a cursor and fill in the data on the screen, such as setting the window title, in onStart() or onResume() ? onStart() would seem the logical place because after onStart() the Activity can already be displayed , albeit in the background. Notably I was having a problem with a managed dialog that made me rethink this. If the user rotates the screen while the dialog is still open, onCreateDialog() and onPrepareDialog() are called between onStart() and onResume() . If the

Activity 生命周期： 生命周期7个方法的调用时机： 1）onCreate：第一次创建这个Activity时， 也就是系统中没有缓存当前的Activity时，这个方法首先被调用。调用之后这个Activity就会被压入所谓的Android Task栈中缓存起来，下次用时出栈就可以。所以，为了更加节约资源，我们一般把Activity所对应的layout中拥有的组件首先使用private作为这个Activity的私有成员，然后在onCreate方法中初始化，这样只要在Activity创建的时候，初始化一次组件就够了。 2）onstart：当这个Activity成为用户可见状态时， 也就是在手机界面上正确显示的时候这个方法会被调用。所以，如果一个Activity之前已经创建好了，下次再次调用时（比如返回按钮）就会从Task栈中获取直接返回给用户，那么就不会再调用onCreate了，而是先调用onRestart,然后等到用户可见状态时调用onStart。 3）onResume：当这个Activity成为用户可见状态而且用户可以获取焦点时， 也就是在onStart之后，当这个视图可以与用户交互时这个方法会被调用。这个方法调用完成之后，整个Activity就是处于运行状态了。 4）onPause：当一个Activity正在使用，这时另一个Activity开始启动

Resume activity in Android

I have an app with 3 activities. I have the main activity. This calls the second activity, which then calls the third activity. I want return to the main activity without entering the onCreate. This is the code for the third activity: startActivity(new Intent(TerceraActiviry.this, Main.class)); If your Activity is still running, this code will bring it to the front without entering onCreate Intent openMainActivity = new Intent(TerceraActiviry.this, Main.class); openMainActivity.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); startActivityIfNeeded(openMainActivity, 0); in order to get back to

GlobalSettings onStart fires only after first request

由 本秂侑毒 提交于 2019-12-01 06:53:04
I need to run some code only once when I starts the play server. When using the GlobalSettings.OnStart() I notice that the code is executed only after the first (http) request to the server. Any idea how can I run my code just after the server starts and before any request is sent? Thanks That is the behavior when the application is in development mode, play run . When it's running in production mode, play start , then your onStart method will run immediately when the application starts prior to any requests. You can emulate that (or I should say, workaround this unfortunate dichotomous design
