Android :: How To Build Activity - Pause For Few Seconds And Then Repopulate Five TextViews With New Values

Jul 15, 2010

onCreate, MyActivity will display five TextViews. After you touch one of the five TextViews, it will hide three to four TextViews and color one red and one green or just color one green.

I can code everything up to here. But how can I pause for a few seconds and then repopulate the five TextViews with new values, unhide them and make them all white?

I tried a Timer in a new project and can attach the code and make my question less vague.

Here is the main.xml

CODE:................

Here is the TestTimer.java

CODE:.....

The issue is that the Timer executes resetAndContinue and logs two entries, but it doesn't set the TextView color from green to white and it doesn't log anymore

CODE:.............

Android :: Activity Pause Rather Than Finish?

Nov 30, 2009

I see no means by which my activity can pop itself off the activity stack to return the user to the one he was using before it was invoked. Is there one? My purpose is that my app has some data structures built from data provider queries that take 5-15 seconds to assemble and I don't want a lot of latency if it is used in a few one-shot purposes in rapid succession. I'm more than willing to let the system ask my app to die, but I'd like to keep warmed and ready otherwise.

Android :: Pausing A Thread - Activity Pause Timeout For HistoryRecord

Jun 30, 2010

I'm trying to write a game engine in Android, but I don't have much familiarity with threads.

My thread has an attribute, mSurfaceHolder, which holds the surface that I'll be drawing to. The run() method for my thread looks like this:

CODE:.............

STATE_RUNNING represents the state when the activity is in the foreground and the game should be running.
STATE_PAUSED represents the state when another activity has come into the foreground. I'm not completely sure why I need to still draw while it's paused, but that's what I seem to have gathered from the LunarLander example.

What I'm hoping is that while I'm looking at the activity, the game will update and draw (which I test by using LogCat). And then when I go back to the home screen or another activity appears over the top, it will just draw.

Well it does draw and update while I'm watching the activity, so the game loop itself works. But when I leave the activity, it has no effect. Here is the thread's pause() method that is called from the activity's onPause():

CODE:.............

As you can see, to test this method I have logged some messages. Now what I find when I leave the activity is that "Here" is logged, but "There" is not. Now with my limited knowledge of threads (I hardly know what synchronized actually does), I believe this will happen because my thread can't get synchronized with the surface holder. But I don't know WHY it doesn't synchronize. A few seconds after I've left the activity, I see the following warning in LogCat:

Activity pause timeout for HistoryRecord

Any idea why this would happen? There are no problems if I try to start the activity again, the thread just keeps running as it was.

Just discovered something else. The thread pauses just fine if I leave the activity within about a second of having started it. And then it will resume and pause again with no problems at all while the same task is still running. I have no idea why for a short period of time it will work, but if I leave it too long, it won't.

Okay... I fixed it. But I don't think I'm supposed to do what I've done. I've basically removed any synchronization with mSurfaceHolder from both the pause() and the setState() methods (which is used by pause()). No it works as it's supposed to, but I'm thinking the synchronization is there for a reason.

Perhaps the best question for me to ask is this: WHEN should you synchronize a thread with an object by use of a synchronized block? And in this case, what is the purpose of synchronizing with the SurfaceHolder?

Android :: Pause Flash Content In WebView When Activity Isn't Visible?

Aug 7, 2010

I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)

I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.

Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)

Here is a simple test I put together that loads a game on Kongregate which has some background music:

CODE:..............

I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.

I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?

The documentation for the mobile Flash player says:


Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.


This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!

Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

CODE:....................

Android :: Passing Values From One Activity To Another

Feb 11, 2010

I have an app which makes use of several layout-views. Every layout - view also got a class for it, which extend the Activity class. One class for example retrieves some database values whilst offering a search form to the user. Afterwards the user can select one of those values and he gets presented with another screen which gives similar options as the one selected. Anyways, I'd like for the first Activity to be able to send an array with data (Strings for example) to the second one. Right now I show an activity by using:

Intent i = new Intent(this, activitysName.class); startActivity(i);

I have no idea whilst using this construction how I can "initialize" the new object with the String array I want to pass to it. So how should this be achieved ? Should I be using something else instead of an Intent-Activity combination ?

Android :: How To Set / Pass Values From One Screen (activity) To Another?

Sep 30, 2010

How do you set/pass values from one screen (activity) to another? What I have in the R.layout.main view labeled Calculator contains the code for doing calculations. The main.xml contains the layout (view) of the main screen. I have created an options menu which has another screen which shows you setup (R.layout.setup). The dialogsetup.xml contains the layout (view) for it.

When you press the menu button, you get the options menu. If you select "Setup", then it will display the setup screen. Now what I need to do is take the values from the setup screen (radio button and text values) and place them in the main screen so that when you exit the setup screen and go back to the main screen, you can take those values and use them in your main code.

But, the problem is, I cant send values using Intent.

Android :: Build Error Build/core/java.mk:20 On 2.2

Jun 24, 2010

I downloaded the Android 2.2 source code and try to build it. When I executed the make command, I got an error here like this build/core/java.mk:20: *** frameworks/ex/common: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. Then I changed the frameworks/ex/common/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7. Next place, build/core/java.mk:20: *** external/jsr305: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/jsr305/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7

Last one, build/core/java.mk:20: *** external/guava: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/guava/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
By these changes the code started the compilation.

1. Why the error occured?
2. Changes which I did is correct or not?

Android :: TextViews Parametrization / Binding To Model Possible?

Feb 12, 2010

I am new to both Android and Stack Overflow. I have started developing and Android App and I am wondering two things:1) Is it possible to parametrize a TextView? Lets say I want to render a text message which states something like: "The user age is 38". Lets suppose that the user age is the result of an algorithm. Using some typical i18n framework I would write in my i18n file something like "The user age is {0}". Then at run time I would populate parameters accordingly. I haven't been able to figure out how to do this or similar approach in Android. 2) Let's suppose I have a complex object with many fields. Eg: PersonModel which has id, name, age, country, favorite video game, whatever. If I want to render all this information into a single layout in one of my activities the only way I have found is getting all needed TextViews by id and then populate them one by one through code. I was wondering if there is some mapping / binding mechanism in which I can execute something like: render(myPerson, myView) and that automatically through reflection each of the model properties get mapped into each of the TextViews. If someone has ever worked with SpringMVC, Im looking for something similar to their mechanism to map domain objects / models to views (e.g. spring:forms)

What would be the best way to approach this?
