I would need to know when one activity starts or get's focus. I need this notification for any activity regardless of his type, name or whatever - not searching for one specific activity. Checked the ActivityMonitor and the Intent and I haven't found a generic intent for this purpose. Or I hadn't understood well the descriptions from the Intent ACTION_xxxxx.
I open an Activity which has a number of elements... some TextViews, some Buttons, and an EditText. For some reason, when the activity starts, the EditText is focused by default, which causes the keypad to appear hiding the screen. I only want this EditText to be in focus if the user clicks into it. How can I ensure that this View isn't in focus when the activity starts? I've tried calling requestFocus() on one of the buttons, but it hasn't changed anything. Ideally, I don't want anything in focus at all.
I have a listview, and wanted to make some list items to be non-focusable. i.e On pressing the down-arrow key, some items in the middle of the list gets skipped.
I tried the following method. 1. created separate ArrayAdapter class. 2. override getView method. 3. In getView, I called setSelected(false) and also tried setFocusable(false) for some items, but its not working.
I have a TextView with android:maxLength set to 3 and another with android:maxLength set to 7. I want focus to automatically move to the second TextView once the 3 chars of the first TextView are filled up. Is this possible without inheriting TextView and writing a custom implementation ?
I am developing an application in which the user require to register first and than got the user page. For that i have made layout and the layout consist many fields, so, i have made part of layout and also made the separate activity for the each layout. The layout like address, phone, etc... After that i have wrote the code for calling an activity and it works fine. It means when i press the "Next" button the another page will come and it will also consist some textview ,edittext and previous and next button. Actually, i want something different like -- When the user fill the first form and he will proceed to next, the content written by the user should not gone when the user press "Next" button. The content should be there which was written by user. And same way i have have 6 pages like that way to complete the registration process. So, have you any idea to solve above problem? I really need your help because right now i stuck at this point. So, please any body help me out of this problem. I would appreciate your help. I am waiting for your reply.
When changing screen orientation while running an Activity that has both a normal layout and a layout-land file defined (both of which contain a TextView), then that view loses its focus after being restored and a warning is issued on the log:
"Previously focused view reported id X during save, but can't be found during restore."
Is this a bug? I looked at the mID field of that view, and it's identical for both the portrait and the landscape layout.
I coded an AppWidget the user can add to his homescreen. There are a bunch of images (ImageView) in it that perform different actions like starting Activities on click (realised with PendingIntents). To make it easier to navigate through the AppWidget I'd like to use the trackball (as it works with the SearchWidget or FacebookWidget) but I just can't make it work. Here's my layout code for the AppWidget...
So I want to be able to navigate through a bunch of these "Spots" that are all relativeLayouts. How can I make that work out? I'd be really happy about every hint or idea!
My initial activity is basically a splash screen while preforming initialization and login in to network server. To save memory I want to finish() the splash activity once it starts the main menu activity. I still want the remote service to operate. Testing shows it does. But am I going to get into trouble doing this? I know I can restart the remote from the main menu activity but I am trying to save overhead by not starting it twice. The remote service is required by the splash activity.
I have a service that listens to a socket. When receiving certain input it is to create an activity. When receiving other input, it is to kill this activity. I have struggled for a while to make the service communicate with the activity through AIDL (http://developer.android.com/guide/developing/tools/aidl.html), but this seems to not be effective. I think AIDL is only effective when the process that is to be talked to is a service, not when it is an activity? I would love some directions or suggestions on how to solve my problem.
I need to start a animation automatically for a activity without any user clicking. I know when activity is not ready, animation could not start. I used a thread to start it, however it is still not working.
I am getting a crash intermittently when my Activity starts up either initially or when the screen gets rotated I get several log messages which I have been unable to get any insight from: timeout expired mFreezeDisplay=1 mFreezeCount=0 App freeze timeout expired Force clearing freeze then lots of: Lock_layer timed out (is the CPU pegged?) Key dispatching timed out then I get ANR annotation: keyDispatchingTimedOut the trace has alot of sending signal 3 to alot of PIDs
I have an activity which loads a TableLayout. This is made up of TextView and EditView fields. When I run my app within the emulator the layout appears correctly (WITHOUT the soft keyboard appearing). When I run the app from a device (HTC Evo) and enter the activity the soft keyboard ALWAYS appears. I tried doing an OnFocusChange() for the first field in the layout and then doing:
I have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult() to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input. The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible" set in the manifest under the <activity> tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show.
When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts?
If I have a button that starts an activity, and the activity sometimes takes a second or two to throw up its own view, how can I most simply and reliably protect against the button being clicked multiple times and kicking off multiple (identical) activities?
I just created a simple application, that starts the Dial Activity and place a call. I did not provide any permission in the manifest file to start a call, but still the call activity starts. I also checked the AndroidManifest.xml file, there is no permission added, still the activity starts.
I have a widget that is supposed to start and stop a service (start it when it's not running, stop it when it is). This is working fine, however, each time the service is started, my app's main activity is also launched, which I don't want from the app's manifest, it works as I want it to (without launching the main-activity, just the service), but then I obviously don't have a main activity anymore.This is how I start the service (I would assume this is the normal way, and I can't see any reference to what might cause the MAIN intent to fire).
I have an Android activity that, onCreate(), will query a database and display the query results in textviews on the UI.The problem that I am having is at some point, users can open another activity and update the database. When they go back to the original activity, I would like for the text views to update with the new database information (so, I will re query the database and display the info).Another thing that I am willing to do is to take the new input from the user (in the new activity) and directly update the textview in the existing activity (without having the existing activity re-query the database). But I'm not sure how to do something like that either.Can someone please inform me on the best way to go about doing this? The only solution that I have found so far has to do with broadcast receivers, but I'm not sure if that is best suited for what I have to do.
I have an Activity that keeps running after the Home button is pressed (naturally) and of-course the focus is in the home screen, and when the running process ends I need to restore the focus on that activity. In more PC expression, I need to maximize the application.
I have been in problem of the Activity life-cycle. All though i read lots of docs on it put on getting clear picture on it. I have Activity A. In that activity I have menu options. If we click any option it opens the respective activity like if i click on 2nd button it opens Activity B Now again Activity B has same options into it. When user clicks on 1st button then i need to go back to activity A. So using this. Intent intent = new Intent().setClass(context, Articles.class); startActivity(intent); So always it starts new instance of activity and fetch data from DB. I want something like Activity A can be resumed back as it was.
I have an activity that is showing a video and when the user clicks a button, a new activity is launched. When the video activity stops, I pause the video view. When the video activity starts up again, I try to resume the video view videoView.start(), however, the video starts over from the beginning. I'm thinking that the buffer must be lost somewhere, so I now try to capture the current position via videoView.getCurrentPosition(), however, this is always returning 0.
Anybody know how to resume video playback when an activity starts up again?
I have an android activity, with two elements: EditText ListView When my activity starts, the EditText immediately has input focus (flashing cursor). I don't want any control to have input focus at startup. Stop EditText from gaining focus at Activity startup? I tried: EditText.setSelected(false); No luck. How can I convince the EditText to not select itself when the Activity starts?
I have an activity that begins with almost a page of text, then has a few form controls. When the activity launches, the first form control takes focus and the screen scrolls down to make it fully visible. When this happens, the text at the top is off the top edge of the screen. When the screen comes into view, I want the text at the top to be visible. So, onCreate, I tried sending a message to the Activity's overridden handler to do the following:
ScrollView main = (ScrollView) findViewById(R.id.main); main.pageScroll(ScrollView.FOCUS_UP); This did nothing. I then tried: main.scrollTo(0,0); This also did nothing. I then tried sending the message from onResume instead of onCreate. This also did nothing. How to force the scrollview to actually scroll?
I know the title it doesn't explain my problem exactily. It's better explain it with an example. I want put up-down arrows over inbox activity. I can select each row in the inbox message list pressing up or down arrow. I'd tried it showing two activities at time starting a new thread, but I can't get it. However, if I could put my arrows another problem appears: how can I tell inbox activity focus his rows? Then, I thought maybe I resolve my problem installing NDK, but I have a lot of problems installing it. Finally, you could think, another solution could be manage myself inbox message list; but this is not an scalable solution for me.
I have an application, which (for the sake of simplicity) has two types of activities - Overview and DetailView. The Overview activity shows a list of steps and allows the user to start a DetailView activity corresponding to the step chosen.
In the DetailView activity, the user can start another Overview, which shows different steps than the ones in the parent of the current DetailView.
In the Overview, DetailView is started by using startActivityForResult (). In the DetailView, when the user decides to start a second Overview, I call setResult () and finish () and then start the new Overview. In this scenario, onActivityResult () and finishFromChild () do not fire. Instead, they fire when the parent finishes (?).
I have a Timer which executes a TimerTask every 30 seconds. I only want the timer to launch a new TimerTask if the Activity is displayed i.e. if the user receives a phone call or launches a new activity the Timer will stop. I then need the Timer to restart when the Activity is re-launched and comes into focus.
Now this should be easy, I override the "onWindowFocusChanged(boolean hasFocus)" method and either start or stop the timer depending on the value of has Focus. The way I start the timer is to create a new Timer object and TimerTask each time and the way I stop the Timer is to call the cancel() method on the Timer object and set timer to null.
My problem is this doesn't always work, if I launch the activity which has the Timer and switch orientations quickly (to start/stop the Activity) I find the Timer is not always canceled and I end up with multiple Timers launching TimerTasks at an ever increasing rate.
Like the title says, I need to detect when my app loses focus because another app is launched (Phone call comes in, or user hits Home etc.). Overriding Activity.OnStop does not work because that is called even when switching activities within my app.
I have a problem with my app, it haves a lot of activitys, two of them haves googlemap views. My A activity haves a full mapview and my B activity haves a small map view. OK, when i am on the B activity and press back key somethimes until i return to my A activity, the map of my A activity shows with errors, with a black zone in the down part of the window. THis only happens when i press back from the B activity. Code...
