Android :: ListView And OnItemSelectedListener And Clicking / Touching

Sep 13, 2009

1. When does OnItemSelectedListener get called?My expectation was that when an element of a ListView was clicked/ touched that the OnItemSelectedListener would be called. My OnItemSelectedListener is not called when a list element is clicked/ touched. (It is called if the list has focus and I move through the list with the arrow keys in the emulator) Is that the way it works? This ListView has an adapter that supplies TextViews for drawing the list elements.

2. With a ListView set up this way who handles display of selected list items? Does the ListView do it or should the adapter configure the views it supplies to make them look "selected?"

Android : Change Item In Listview After Clicking?

Apr 10, 2010

I've created a rather complex layout for listview rows where only the first line is visible (the rest use android:visibility="hidden"). When an item is selected, I want all the invisible objects to appear (selected.setVisibility(1)) - checking first if I have to hide again the previous selection.

Here's the (simplified) code..

The problem is that this only retrieves the invisible items in the first Listview row. What's the way to access ListView rows and change 'em?

Android :: Clicking A Rotated ListView Gives Wrong Coordinates

Aug 25, 2010

I have a ListView that can have one or more clickable items. When I apply a rotate animation the coordinates that are clicked correspond to the original position of the ListView items. For example a list with one item in portrait mode rotated 180 degrees will have the item upside down on the bottom of the screen, but the item gets the click event when I click the top of the screen. 180 degrees is just an example I want to be able to move an arbitrary angle.

I've looked through all the listView properties but none seem to have any effect on the clickable coordinates. I would assume willChangeTransformationMatrix would do the trick but it doesn't, neither does invalidate or invalidateViews. Is there a property I'm overlooking or how would I go about moving the coordinates to the right place?

sample code- list items highlight correctly when clicked, rotate with dpad_center, after rotated items highlight when original position is clicked. I've tried animating the animation, animationSet, and layoutAnimationController all same result.

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

Android :: Ignore OnItemSelectedListener Firing On Create

Mar 3, 2010

I'm creating a spinner and I've added an OnItemSelectedListener to it. However I've noticed that it fires on create. Now I was wondering if there was a way to ignore/discard it. I know I could use a boolean value, but that's a bit "dirty".

Android : Navigation Into GridView Does Not Trigger OnItemSelectedListener / Fix

I have a layout that looks like this (some attributes removed for brevity)

<RelativeLayout>

When I navigate using the DPAD from the button to the gridview, the OnItemSelectedListener is not fired. However a new layout pass is perform. Why is this ? Is this an android bug & my bug?

Android :: Spinner - How To Do Distinguish User's Actions From Computer's Actions In OnItemSelectedListener

Nov 17, 2010

I'm in a trouble managing a spinner. I have a spinner with its adapter. I initialize the spinner with a list of values when starting my activity. Then I force the selected value to be the one used in the object that I manage.

Once the screen is initialized :
When the user selects a value in the spinner, according to the selected value, I may continue (or not) to another activity for let the user choose a complementary and necessary value.

If the user "cancels" this second activity, I want to rollback the spinner to its previous selected value, and cancel some actions made in the meantime.

If the user goes to the end of the second activity, everything is fine and I want juste to refresh the spinner display with the datas selected in the second activity (I overload the getView method in the adapter to do this).

Overall, I can easily do all of this, however, when I force the selected value in the spinner at the begining of my activity, or whene returning back from the second activity by "Cancel", the change value event is catched and the second activity is triggered (the user did not click anything at all).

How would you allow the second activity to be lauched only if the change of the selected value in the spinner is due to a manual action from the user, and prevent that same second activity to be launched when the value of spinner is changed "in the code "?

I tried many solutions, as setting a boolean into the adapter that tells if the next event will be raised because of an "in the code" action.

Or also putting a boolean in the adapter that tells if the adapter has initialised itself, and I force that boolean to true on the forst change catched event.

Android :: WebView Word Touching Ability

Oct 2, 2009

I was wondering whether there was a way, if you have a webview with some html being displayed in it, to obtain which part of the html is touched by the user. For example, say I have a webview that's displaying, in just plain text (no links), the following:

The quick brown fox jumped over the lazy dogs.

If the user touches the word "lazy", can I somehow obtain information that he has touched that particular word? Perhaps there is something in the WebView or WebViewClient classes that maps sections in the html data to x, y coordinates?

Android :: Awake Phone By Touching The Screen

Jan 4, 2010

I own an HTC Hero and the phone can only be awaken by pressing the menu button or the power off button. Dunno if it's like this for every Android phone. I'm looking for a way to awake the phone by touching the screen. My idea is to replace the KeyGuard with something else but instead of awaking the phone by pressing one of those buttons, I would like to do it by touching the screen. Is this even possible or the Androd framework doesn't provide this functionality at all?

Android :: Simply Touching Screen Reduces Fps

Aug 10, 2009

Try SpriteMethodTest, set 100 sprites, select OpenGL / Use VBO, let it run for a while. You will get something around 20ms / 50 fps. Now run it second time, and simply touch screen while test is running. You will get something around 35ms / 29 fps. So it is 15 ms difference. As I understand, the answer is simple - it is that dispatcher thread running with THREAD_PRIORITY_URGENT_DISPLAY priority.Setting THREAD_PRIORITY_URGENT_DISPLAY priority (will it work on non- ADP firmware?) on renderer thread yields 30 ms / 33 fps.

Android :: Keep App From Restarting When Touching Icon From Home Screen

Mar 10, 2009

I want my application to resume what it is doing regardless of where I press the icon (Home screen, app picker, or running apps). Right now if my app is in the background and I press the icon on the home screen, the app restarts with my Main Activity. Once here, if I press the back button the app resumes from the activity it left off before it was put in the background. If it's running in the background and I hold the home button and select my app from the current running apps, it resumes correctly. How do I avoid my app from going to my Main activity when it is selected from the Home screen or app picker? I have tried adding the following in my Manifest XML file, but it doesn't help: <activity android:name=".Main" android:launchMode="singleTask" android:alwaysRetainTaskState="true" android: label= "@ string /app_name">

Android :: Setup An ImageButton To Change Only When My Finger Is Touching It?

Oct 26, 2010

I want to create an event to change what my image button looks like, but only when it is being pushed down. So far I have been using an onTouch listener, but that just changes it permanently. I can't find anything like an onKyeUpListener() type of thing for the button.

Does anything like this exist? code...

I'm trying to do something in my app where you have to hold your finger on the screen for more than 30 seconds. After about 30 seconds, it stops sending onTouchEvents for that part of the screen, almost like a "dead zone." Tested on a motorola droid, and is there any way to stop this from happening?

HTC Desire :: Screen Scolling Downwards Without Touching

Jun 24, 2010

waiting for a swop out but just wondering if anyone has had a problem where the screen scrolls downwards of its own accord. Sometimes if on the browser, the screen will start going down the links. It's not just a browser thing either and can happen on any app or screen.It's an occasional thing. I've eliminated finger prints (put on a screen protector and it still happened), sunlight hitting the sensor (can happen indoors in the dark) and I've done a hard reset. It's driving me up the wall and I've been waiting 10 weeks for a replacement from T-mobile now (although the keep refunding me money so I can't complain too much).

My tablet has a problem that it usually (not always but most of the time) disables all sounds when I touch the screen. Depending on how long I touched the screen the sounds return immideadly or few seconds after I let go. When the sounds return it plays some of the sounds that should have played when I was touching the screen.

Android version is 4.1.1 and model number of the tablet is rk30sdk.

Motorola Droid X :: Charge Phone Without Touching

Jul 18, 2010

For all of you having battery issues (lasting only a few hours, etc) I think I've found a fix. Yestarday my phone was dead after only being on for about 6 hours. I got home about 10 hours after it died. I left it plugged in for about 2.5 hours until it said "Charged". *Note* First it said "100%" but took about 40 minutes until it said "Charged". That was about 10 PM last night. I ran some movies on it for 3 hours with Full Brightness on. I went to bed without plugging it in. This morning I did another 2 hours of movies. It said 50%. After rebooting it said 60%. Another 42 minutes of movie watching, reboot, still says 60%. Conclusion: If you completely discharge your phone then let it charge full without touching it during the charging it seems to fix the battery.

General :: Dial Immediately When Touching A Contact?

Oct 3, 2012

Replaced my Droid X with the RAZR M.

How do I create/edit a contact so that SMS/Text is not an option for a number. I want to hit that contact and have it immediately dial. Some contacts I imported from gmail are already like this but new contacts always have phone or text as the options so I have to select the phone icon to actually dial.

Problem came up because the default voicemail app keeps trying to sell me Visual voice mail. The default Voicemail contact number is not editable so I can't add my pin. Finally deleted the default contact and added my own. So far so good except it always wants to know if I want to send a text?

Running my finger along the side of the case I noticed a weird sensation that at first I though was the finish on the casing, but it registered as more than that, so I unplugged it and it went away. Have since discovered that the sensation is only present when plugged in, but NOT charging - i.e. power light is green.
