onresume

问题 I'm developing an audio application. It plays sounds in the background and I want it to turn off when an incoming call happens but not when the screen locks. My first chance was to call player.stop() on onPause as I thought it will do the trick when incoming or other applications will run on top. But I found that screen lock calls also this onPause event. Is there any chance to get the cause of that calling? 回答1: I believe this article has what you are looking for: http://thinkandroid

问题 I have read several posts on here and elsewhere about the life cycle but I'm still confused. What do we store in the onpause, how do we store it and how do you recall it in the onresume Method. Any more info and if possible a detailed example would be greatly appreciated. 回答1: Is this what you mean For further explanation onCreate(Bundle) is where you initialize your activity.

问题 In my current application the onResume function is triggered when I load an Activity for the first time . I looked into the Activity Lifecycle, but I didn't find a way to prevent this from happening. Can I prevent the onResume() function from loading when an Activity is loaded for the first time, without using SharedPreferences? 回答1: Firstly, as RvdK says, you should not modify the Android Activity lifecycle, you probably have to re-design your activity behavior in order to be compliant with

问题 I'm developing an app for Android, and I want it to pause the music when you press the home button (onPause).

There are no Exceptions shown in the LogCat... So I have no idea what is happening. Does anyone have any suggestions as to why this might be the case? -EDIT- I do get this error in

问题 I had 3 activities in an android application. The application will exit when I press back button in each activity. Using the following code. When I press back from the third activity, the application exits fine but when I relaunch the application by clicking the app icon, then the third activity will launch again.

问题 I have a layout in which I have dynamically added custom views at a push of a button. These layouts extend LinearLayout and each carry their own unique Action objects. The views will disappear, however, if onCreate is called again, when the user navigates away or rotates the screen. I want to keep these custom ActionHolder views there. To add to the problem, the ActionHolder objects contain sensitive information. The Action objects themselves store a live timer(that is supposed to keep on
