Android :: Can't Click On An Animated View / Fix It
Sep 16, 2009
I have a TextView on which I set an onClickListener.
I assign a Traslate Animation to this TextView, so that it moves from position A to position B in the screen.
The Animation works as expected.
My problem is due to the fact that it does not matter in which position the TextView is during its movement: in order to trigger the "click event" I need to touch the screen only in the starting position (A).
EXAMPLE: Imagine that the TextView is in the bottom left corner and it starts moving toward the top right one. Imagine that the TextView is now in the center ofthe screen. If I touch the TextView where my eyes "see" it (= in the center of the screen), nothing happens. Else if I touch the starting point at the bottom left of the screen (which is a blank place because the TextView has moved from there), the event is triggered.

I want to have a ViewGroup with another View in it. The user should be able to move the other View around the ViewGroup, and fling it away. However, the inner View shouldnt only move, it should also scale and so on (so we dont restrain ourselves to just movements). I don't really know the best way to implement it.
First I though about using a ViewGroup pretty much as it is (i.e. take advantage of the already-written methods). Then I could do the flinging with an Animation. However, when I move the View around with my finger, wouldnt I have to do a requestLayout, since the View changes size when I move it? Or could I just set a transform?
The other alternative would be to override the draw-method and do most of the work myself. For instance, when the user moves his/her finger, I could get a cache of the View and just paint it on the Canvas (with some transform). However, how would I do the flinging then, without an Animation? I could use a Scroller/VelocityTracker, but What would "drive" the repaints? Which is the best way to do this? Also, I won't have just one View, but a couple of them, so I'd like the solution to be effective.

When we tried to display an animated gif image using image view, nothing was displayed on the screen. So, we are suspecting whether image view is not supporting animated gif.
If we place an animated gif file in gallery then thumbnail is not displayed.

I am trying to add a webview in my app to display a web page. However, every time I click link on the web page, Browser will be launched to display content in that link. I understand it is something about intent but I am still wondering is there any simpler method to ask webview to display link content within its View ?

I'm currently writing an app displaying a MapView showing a google map. I used the "hello map view" tutorial from http://developer.android.com/resources/tutorials/views/hello-mapview.html and this works so far: the map is displayed, centered and zoomed correctly, even the OverlayItems I added are displayed correctly. But when I click on one of those overlay items I added, the application crashes with a null pointer exception:
07-23 16:24:48.167: ERROR/AndroidRuntime(2530): java.lang.NullPointerException
07-23 16:24:48.167: ERROR/AndroidRuntime(2530): at com.android.internal.app.AlertController$AlertParams.<init>(AlertController.java:753)

My understanding is that when you have a view that's too small to easily touch, you're supposed to use a TouchDelegate to increase the clickable region for that view. However, searching for usage examples on Google turn up multiple people asking the question, but few answers. Does anyone know the proper way to set up a touch delegate for a view to, say, increase its clickable region by 4 pixels in every direction?

What I´m trying to do is to create a list (using a list view) of items (which are views inflated from the same layout) what must be clickable. At first I thought that all I had to do was to add an onItemClickListener to the ListView so if the used clicked on any of the views that composed this Item the listener would react. Well, I was wrong. I´ve tried a lot of things, including setting focus and focusontouchmode off for each of the views that compose the item´s view but it still doesn´t work. Any tips here? Can I archive this result? Oh, also ... this list view is in a dialog and the listener is in the activity that builds the dialog.

I am using one class which extends ListActivity and One class extending BaseAdapter.
The Base Adapter uses getView function to inflate layout from xml.
The xml contains a text and a button to delete the row of list.
Please let me know how to handle the button click in the ListActivity class.

I have a tab activity with three tabs and I want to display a listview in each tab. The list populates correctly, but for some reason I can not get the context menu or itemclicklistener to recognize gestures on the listviews. Anyone have any ideas why this might be? Below is my onCreate method: @Override public void onCreate(Bundle savedInstanceState) { super. onCreate (savedInstanceState);setContentView (R.layout.armory_header); TabHost mTabHost = getTabHost(); mTabHost.addTab (mTabHost. newTabSpec ("1"). setIndicator ("Weapons"). setContent (R.id.page1)); mTabHost.addTab (mTabHost.newTabSpec("2").setIndicator( "Armor" ).setContent(R.id.page2))TabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories"). setContent (R.id.page3)) ; weapons = (ListView) findViewById(R.id.weaponlist); registerFor ContextMenu(weapons) ;weapons.setOn ItemClickListener (new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {// TODO Auto-generated method stub listId = weapons.getId(); position = arg2; showDialog (DIALOG);armor = (ListView) findViewById (R.id.armorlist) ;register ForContext Menu(armor); armor.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItem Click(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub listId = armor.getId();position = arg2; showDialog(DIALOG);

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);

I have a ListView in my Activity. I am trying to catch both a click and a long click (which should bring up a context menu).
ListView lv = (ListView) findViewById(R.id.MyListView); ... lv.setOnItemClickListener(this); lv.setOnCreateContextMenuListener(this); ...
I notice that if I have both the click and long click listeners up, I won't ever get the long click listener (i.e. the context menu). If I remove the setOnItemClickListener() call, i get a call into
@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

When I DL'd the GDE app, I accidentally set my stock droid "HOME" screen as the default screen when the popup box came up asking me to choose between stock Home and GDE. Now when I click on GDE and click the home button, it switches back to the stock Home screen. How to I switch the settings now to set the GDE app as the new home screen?

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

I am trying to make a map overlay animated much like MyLocationOverlay does. Currently the only things that I can see to make animated are Views but Overlays don't extend View functionality. My next thought was to try to lodge a View into the overlay, but the redundancy makes it seem like this solution is incorrect. I grabbed the android source hoping that I could just look at MyLocationOverlay source and that would let me know how the animation was supposed to be done, but I can't find the source for anything involving maps. If that is available somewhere it would help. Can someone point me to the MyLocationOverlay source or let me know what the paradigm is supposed to look like for animating map overlays?

I would like to make a simple 2x2 widget that displays a canvas that's updated every second - how can I go about doing this? I noticed you can't make the onUpdate() update more than every half hour now, so that shoots down that idea...

Any good weather apps(or direct sites) with ANIMATED radar that will load on non-Flash Android.Droid-X(until Froyo comes out...for real).I noticed Weather Channel DOES have an animated app that will load but it takes forever for it to load slower than animated radar would load on my Storm(which was relatively quick) but I thought this Droid-X was supposed to be fast. Yeah I know the problem is probably on TWC's side of things as they always seem to be slow.Had Accuweather on the Storm and I had the animated radar saved as a favorite and could one-click to get it.

I LOVE the animated weather widget that is on the HD2, Hero and Evo.I switched to the Nexus One because it fitted my needs better than the others did.Am I missing it or does the Nexus One not have the animated weather widget?I didnt think that not having an animated weather widget would be a big deal, but I am really missing it.

We are doing some prototyping for an Android app and we wanted to use Animated GIFs via webpages to get a sense of animation. Unfortunately, we have found that we can't do that on the Android's browser (or Opera for that matter). I've read some posting saying that this might get fixed but there were never any specific dates. Does anyone have some news on when we might be able to use Animated GIFs in webpages? If not, does anyone have any suggestions on good ways to develop quick animated visual prototypes of apps for Android? In particular, our design folks (who are handling the visual stuff) know HTML, Javascript, J-query but don't know Java and we would prefer to NOT have them learn another language, if possible as this is really just for rapid prototyping.
