I have an application with main view having a search button. On clicking the search button, search results are displayed in a text view. When I hit the back button at this view, instead of navigating to the previous screen, application itself gets closed. Could anybody please let me know how to go back to previous screen.

View 2 Replies View RelatedIn my android application i have a video list screen,a buffering screen and a videoplayer screen.
As soon as the user clicks an item from videolist screen ,he is navigated to buffering screen and then to videoplayer.
In the buffering screen i am using Async task and doing the loading process in on background process.
Now my issue is like the user if has selested a video then gets navigated to buffering screen.But if the user clicks back when he is in buffering screen then initially he is getting navigated to videolist screen but immediately after that again he is navigated to videoplayer screen.
What i would like to have is either the back button should be made disable in buffering or should prevent the player tostart if back is clicked.
I have to develop one android application.
Here is the scenario:There are many images in a linearlayout. When selected, the layout should be displayed with another(gradient_bg_hover.xml) background. This works well now.
Now, I would like that when I open a new activity and come back to this one, the last selected layout should still be the highlighted one (with the (gradient_bg_hover.xml) background).
Now i have used below code for highlighting the image when pressed:
[HIGH]
LinearLayout ar = new LinearLayout(this);
ar.setOrientation(LinearLayout.VERTICAL);
ar.setPadding(3, 3, 3, 3);
ar.setLayoutParams(artiLayoutParams);
ar.setGravity(Gravity.CENTER);
ar.setBackgroundColor(Color.parseColor("#666666")) ;
[Code]...
In OnClick function i have wrote the below code:
[HIGH]
private OnClickListener mArticleClick = new OnClickListener()
{
@Override
public void onClick ( View v )
{
int object = v.getId();
v.setSelected(true);
[Code]...
Here i have to clicked one item means it is go to next activity.afterthat i have clicked back button means the selected item is stay on highlighted with another background.afterthat i have selected another item means its go to next activity.now i have to click back button means these item only highlight with background....but the pervious item also highlighted....
I wish to need the o/p like :
The last selected item only highlighted after click the back button...
So i have used sharedpreferences :
I have declared int prevPosition = -1; globally...
[HIGH]
ar = new LinearLayout(this);
ar.setOrientation(LinearLayout.VERTICAL);
ar.setPadding(3, 3, 3, 3);
ar.setLayoutParams(artiLayoutParams);
ar.setGravity(Gravity.CENTER);
[Code]...
In Onclick method:
[HIGH]
private OnClickListener mArticleClick = new OnClickListener()
{
@Override
public void onClick ( View v )
{
int object = v.getId();
[Code]...
But my background color is not staying after press the back button...
I started a small android application to learn. I placed an input text and button on the screen. That shows on the emulator. After i press the button(which has an onClickListener) the application cracks and tells me on the screen of the emulator : "The application... has stopped unexpectably.Try again" and i have a "Force close", which of course closes the application.
I cleaned and rebuild the project a lot of times. i have no errors shown.(using eclipse)
this is the layout/main.xml code...
I have an Activity with a list that is bound to a ListAdapter reading data into a ArrayList from a database. All is well when the data is first loaded. While the Activity is open and the list is being displayed it is possible and likely that the data in the database will be updated by a service but the list does not reflect the changes because the ArrayList does not know about the changes. If the Activity is no longer in the foreground as would be the case if the user goes to the home screen and then is brought back to the foreground I would like for the Activity to not display what it did prior but rather reload the data using the ListAdapter the view is bound to. I think something needs to call finish() but I am not sure what.
This is what I have in the Activity.

The camera button on the android emulator is disabled. I can't click on it and when I hover with the mouse the background is not blue like in the other buttons. I've tried to add "camera support - true" hardware but the button is still un-clickable. How can I click on the button? What should happen when clicking on the button? I don't have an real android device so I might be able to click on the button without knowing it.

View 1 Replies View RelatedI 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.
Application (non-wanted) behavior - application is started, some text is put into text-box and notification is created through button action. user "clicks" the home button, application is "minimized", notification is available in bar user selects the notification and the application is "maximized"
BUT - instead of the original instance, new instance is started (e.g. in the newest instance is missing the original text; when the latest instance is closed there is still the original instance with original text ) .
The code of the notification method
CODE:.....
I have also in the manifest xml file following tag android:launchMode="singleTask"
But it is still the same...The main problem is double/triple initialization of the application, i know that there are other means to preserve the values in resumed applications. Also it is needed that the applications stays running in background as the main functionality is the streaming of internet radio.
What is missing in the code ? What kind of information from my side is missing for to troubleshoot the issue ?

View 2 Replies View RelatedDoes anybody have any insight as to why a game appliction would restart when exiting with the back button. It does not automatically restart when using the Home button to exit and this only occurs one time (after the second attempt to exit with the back button, it exits cleanly). Also, I can reproduce this consistently on the Motorola Droid, but have not been able to reproduce on the G1 or the emulator running 2.0. I've tried changing the launchMode of my activities, but have not found something that works. These are my activities:
1. Splash Screen, Single Instance, Main/Launcher 2. Help, Single Instance 3. High Score, Single Top 4. Preferences, Single Top 5. Options, Single Top 6. Game, Single Top, with SurfaceView
The steps to reproduce the problem are: 1. User starts application, launching Splash Screen Activity 2. User starts game, launching Game Activity 3. Game Activity launches Options Activity (for result) 4. Game Activity restarts with result and game begins. 5. Pressing Back Button returns to Splash Screen Activity 6. Pressing Back Button again, briefly shows home screen, then relaunches Game Activity which starts Options Acitivity 7. Pressing Back Button again finally shows the home screen
Either exit button or back button only can be implemented in my application. But i want both the implementations in my application
View 1 Replies View Relatedi have a drawer menu, when i press one of its buttons to start a sharing intent as below:
Code:
Intent iFriends = new Intent(Intent.ACTION_SEND);
iFriends.setType("text/plain");
iFriends.putExtra(Intent.EXTRA_TEXT, "http://www.liveplus.mobi");
iFriends.createChooser(iFriends, "Invite Friends");
startActivity(iFriends);
The sharing dialog appears, but if i press the back button, the whole application exits!
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 have noticed while working in the emulator that whenever i get out of my app via any method other than pressing the back button, my toggle button (if pressed) will have its state saved and return to that state when i return to the app. im guessing its because its value gets saved in a bundle and reloaded when i return. when i leave the app via the back button, this does not happen and the toggle is always off when i return. is there any way to get the value of the toggle back if the user leaves via the back button, without having to save the value in a db table? alternatively, if my apps notification is in the status bar, i can be confident that the toggle should always be selected, so if there is no way to save the state, is there a way to find out if my apps notification is currently being displayed? then it would be easy to just set the toggle each time via a quick check of the status bar.
View 1 Replies View RelatedFirst of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?

View 3 Replies View RelatedI'm trying to implement my own phone call handling UI. What I want to do is, if a call comes in, the incoming telephone number and a picture are displayed, and, if I press a button, the incoming call will be accepted/answered.
Sadly, the code does not work. At first, an exception is thrown if I press my answer button:
ActivityNotFoundException: No Activity found to handle Intent {act=android.intent.action.ANSWER
Then I added an entry in the AndroidManifest.xml: I run the app again, there is no exception anymore. However, I doubt the incoming call is not really accepted. Because if the press the Android's screen answer button (green button), the incoming call is accepted and a green in call icon is also displayed on the upper left corner of the emulator screen, while my app doesn't.
I also read the Phone app's source code in android source. There is method such as acceptCall() in the Phone class. But these codes seem difficult for me to use, because there are many imports declaration in the code, such as :
import com.android.internal.telephony.Call;
import com.android.internal.telephony.CallStateException;
import com.android.internal.telephony.CallerInfo;
import com.android.internal.telephony.CallerInfoAsyncQuery;
import com.android.internal.telephony.Connection;
import com.android.internal.telephony.MmiCode;
import com.android.internal.telephony.Phone;
And, if I add these imports in my code, there will be too many errors, such as : "The import com.android.internal.telephony cannot be resolved" What is the right and simple way for my problem?
