Android :: Moving Between Droid Activities On Button Clicks?
Apr 16, 2010
I am writing a android application where, on startup activity view, I have a button "DoIt". When user clicks "DoIt" button, I start another activity with different layout. On newly started activity, I have a button "Back" which should take me to the first activity. How to accomplish this. What code should I write on OnClick method of "Back" button. Also, I want the newly created activity to die after back button is pressed and application comes back to start-up activity.

How would I capture two clicks of any of the physical buttons (including the optical button)?Something like what QuickDesk does with the two clicks of the Home button.

I understand that trying to capture home button clicks is a hack, but I need to atleast close my current activity when the user clicks on home button. Is there anyway I can tell the system to close this activity is the user clicks on home button? If so how can I do that? I need to do it as I am listening for location updates and I want to stop the updates and also need to trash any location that was available to me previously. I need to do this just in case any user while in that activity clicks on home button and changes the location settings.

In my current application design, I have an activity class application.java (which starts on launching the application), and it does not have a layout(UI screen). I call another class called servicebind.java from the onCreate method of my 1st class. here I bind to the local server (bindServer()). i call back the application class through an intent. Once I am back to my application class, I call my activity class called welcome.java which has a layout/UI. When I run this application, I am able to see the welcome screen. But the problem is, when I click on the back button, I get a black screen with just the title on top. I have to hit back button 3 times to exit the application.
The reason I see from the logs is that, the 1st 2 activity classes (application.java and services.java) does not get destroyed unless I hit the back button. So the 1st time I hit back button, the welcome activity gets destroyed. the next back button destroys the servicebind class and final back destroys the application class. Is the reason because these classes dont have a UI to display in the onCreate method. I do not want to change my design where I bind the service in the servicebind class and call the welcome activity in the application class.

I'm developing a real-time informations about train. The application will connect to a XML plateform that will give the next trains with a station given. I'm a beginner in Android development, and I'm stuck to a class- problem (I think...).
In details, the problem is, when I start the application, the user get a screen with 2 buttons, one of them get the user to a new screen with stations list. But, my problem is, I can't put buttons and lists in the same class. I explain, to get a list on the screen, I have to put : "public class NextTrain extends ListActivity {" but the buttons function doesn't work (the app crashs). By the way, if I put "public class NextTrain extends Activity {" the buttons works but not the list (no crash, but the screen doesn't display anything).

I am writing a application where I am dealing with 4 activities, let's say A, B, C & D. Activity A invokes B, B invokes C, C invokes D. On each of the activity, I have a button called "home" button. When user clicks on home button in any of the B, C, D activities, application should go back to A activity screen ?
How to simulate "home" button in this case ?

I have created two tabs, say TAB1 and TAB2. For TAB1, i have loaded one Activity, say ActivityOne, into TAB1 as Code...
When we click on that button ActivityOne_One will be launched under same TAB1. In this application i have two problems:
1) If i want to go back to ActivityOne under same TAB1 by using traditional BACK button on emulator it is not working..
2)ActivityOne_One is launching with no animation(like sliding from right to left) effect.
If anyone know about any one of these, give your advice.

When i leave my app after pressing home button and then re launch it from menus it behaves in a strange way.Sometimes it launches the same activity on which i pressed home button.But sometimes it launches the first activity of my app. One reason for this could be that whenever system has memory shortage it clears any activities existing in But the strange thing is if i press back button from first activity it takes me back to the same activity on which i pressed home button and all other previous activities are also there(like if i press back button again previous activities also exist.)I haven't set any launching mode for any activity in my app(like single instance etc).What i don't need is that previous activities load on pressing back button on first activity.

Unfortunately I dropped my Droid the other day and now the top left area of my screen has a noticeable click or gap to it. I remember a thread where someone used electrical tape to fill that gap. Just wondering what the rest of y'all have done and what the best solution is.

Anytime I try to access my camera utility, through pressing the camera button, choosing the camera icon, or choosing the camcorder icon, the auto focus clicks like normal but the program does not open. The screen just goes black for a second and opens once more on the main screen. When I take the SD card out it works fine, but otherwise nothing will work. I have tried a factory reset, uninstalling several programs, and power cycling over and over again.

i'm looking to get called when the user taps on any part of a map view and i'm having no luck so far. none of these produces as much as a peep when the map view is clicked.i did some googling and found the thread.which suggests that overriding mapView.onTouchEvent() works, though calling setOnTouchListener() doesn't. however, onTouchEvent() didn't work for me.

I have an app widget which runs neatly. However, I am unable to highlight a click on a linked item. I've seen it in the standard app widgets like 'Music' and 'Power Control', for instance. Moreover, I've also been studying the Music app widget's source at album_appwidget.xml. The only thing I could think of is the LinearLayout defined at lines 23-35 which states android:clickable="true".Unfortunately, this does not work for me. So does anyone have a hint on how to highlight a click on an app widget? I've tried the LinearLayout, TextView and Button. None of them displayed a border as a highlight.

I have an EditText that shows time. After user clicks the EditText I want to show a TimePickerDialog, so I set a View.OnClickListener to my EditText. But the OnClickListener is behaving wierdly - I touch the EditText and then software keyboard appears (which I don't want). When I touch again, OnClickListener.onClick() is finally called and the dialog appears.What should I do if I want the dialog to appear immediately?
