Android :: Set OnClick For Whole Screen?
Aug 24, 2010
I know how to set a listener for.. let's say a button or a editext so that when clicked some action happens:
buttonOReditextl.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Action goes here } });
how can I set a onClick event for when the user taps/ clicks on the screen? or the surface.. I'm not sure? I want a picture to be taken when the camera is on.. but don't know how to make a listener to all the camera view instead of having a button to take a picture.

I wrote a home screen widget with one image on it. When the image is clicked, browser will be opened for a url link.
Generally, it is working. But a weird thing is that, when I click background, then click the picture, the browser will not be open. Until I click the second time on the picture, the browser opens. The steps to reproduce is below:
Click on the home screen widget background.
Click on the image on the home screen. The browser is not opened.
Click on the image again. The browser is opened.
If I didn't click on the background, the image will react to click very well, i.e. browser will be open when the image is clicked the first time.
The widget XML file is as below:

just a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]

I am trying to create a list view where each item will open up a new view and display a picture and text describing the item when said item is selected. I am working with this tutorial novice-tutorials-f8/opening-windows-i-e-webbrowser-reacting-on-clicks- t22.html?hilit=reacting%20on%20Clicks
so is there a way i can use this code to open up a new view
[code]@Override protected void onListItemClick(ListView l, View v, int position, long id){ super.onListItemClick(l, v, position, id);
// Get the item that was clicked Object o = this.getListAdapter().getItem(position); String keyword = o.toString();
// Create an VIEW intent Intent myIntent = null; // The intent will open our anddev.org-board and search for the keyword clicked. myIntent = new Intent("android.intent.action.VIEW", Uri.parse ("" + keyword + "")); // Start the activity startActivity(myIntent);}

I have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed. I think I need to implement onClick for this dialog but I am not sure where to do this. I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.
public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
private static final String LOG = "test"; private DialogPreference mfactory;
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ....................

I guess this is kind of an odd question but i have tried setting onClicklistener on an ImageView and it has worked. But the problem is that the user cannot sense the click. I mean if some of u have worked on other mobile environs(like apple iphone) then wen we click on a Image in other environs then it gives an effect on the image so that the user can understand that the image has been clicked.
I have tried setting alpha using "setalpha" method but it doesnt work. Though the same thing is working fine on onFocusListener implementation. Can some1 suggest a different way to modify the image on click...

I have 3-4 activities in the application and all of them have some event listeners that work nicely.
However only on one activity i simply can't get the event handling to work.
I tried the solution from this thread:http://www.anddev.org/view-layout-resource-problems-f27/ontouch-not-called-t16578.html
It doesn't work for me. I tried to manually set OnClickListeners for ImageViews from java code, android:onClick from XML.
It seems that some other component handles all the events, or my activity doesn't have some permission to handle events.
Should I put something in the AndroidMainfest.xml for my activity that enables handling events?
Hope someone has the idea what should i try, here's the code:

I have an Activity that implements a Gesture Detector to catch the user fling input for navigation to other screens. That was working fine - but - I recently updated a class that derives from my BaseActivity to add an onClick function and now that click event seems to block the onFling from being hit. The onClick is tied to a TextView area (in a LinearLayout) I have on my screen. The resultsClick method is wired to the TextView using its onClick property in the XML layout.
I've tried changing the return values in onSingleTapUp and onDown without luck. I've also tried adding log statements to all the functions below as well. None of them fire when I fling in the TextView area but they do on other areas of the screen.
Maybe I am using the wrong search terms, but I couldn't seem to find an example that addressed this - yet I'm sure this problem has been solved before.

Is there a way to have 1 onClick Lister for many buttons where I can toss a case statement to do things based on what buttons were clicked.
I know I can make 100 different listeners for 100 buttons but I have to think I can create some nifty variables to do it in less lines of code.

I have a listview managed by an adapter that is extending BaseAdapter.
In the getview function im using the convertView to set up a OnClickListener. This OnClickListener work well when I am touching the screen but if I use the trackball of the HTC Desire, I see the row flashing on the screen, but the OnClickListener is not called...
I've read the android dev guide : http://developer.android.com/guide/topics/ui/ui-events.html
and its say that I should receive a onClick event from the trackball...
Im putting here my getview code in case someone see anything strange.

I've spent over a week trying to figure out a way to do a Limited Multi Selection Preference list. Nothing I've tried works. I'm ready to give up on Android if something seemingly simple is so hard. I've been programming a long time and don't remember being beaten up this badly by something like this. I have to assume I am not understanding something basic. I hope someone can point me in the right direction.
Here is the simplest code I can think off that should work. It does not clear the checkbox even when setting it to false, I've tried true as well. Why doesn't that work? If that will not work, what will?

I'm in a process of creating a memory game. My problem is that whenever i click for the second time, i can't even see toggled button. To be clear - first click toggles the togglebutton, so i can see the number it holds, the second click on a different togglebutton is suposed to toggle it, show me the number and then proceed to either set a score +1 if numbers are the same, or reverse them back again if they're different.
Below is the code that i use as my onClick function, i've been thinking about putting some kind of sleep or delay function somwhere in the second "if block" - (if(klikniecia ==2)).
CODE:...........
I think, about setting a delay here, so i can see both of the cards, regardles if the're the same or not before reverting them.

I am working on my first android app and so my first with the Maps API and am experiencing an odd problem. How ever when I click the screen it seems the onClick event is not being run?Have I missed something or am I better off sub classing the MyLocationOverlay I am using and override DispatchTap?How ever i would rather be able to just click anywhere on the map to dispatch the event.

In my layout xml file I have set the android:onClick attribute for a Button element to a function in my activity. So when I click the button the function is called with a View as its argument. Are there any information in that View argument that has the id of the button being clicked? I'm trying to figure out if I have to have one onClick function for every element or if I can use one function and switch depending on the id of the element being clicked.

I have a ListView that uses different XML files to create Views and make items out of. One of these XML files contains a RatingBar. Everything displays and looks excellent. I'm trying to attach an onClick handler to the RatingBar to launch a new Activity. My RatingBar is of style ?android:attr/ratingBarStyleSmall; so it's just an indicator (I want the small RatingBar click to take the user to an Activity where they can do various ratings).
My problem is the onClick handler for the RatingBar never gets executed. What makes it more interesting is that I've used the same code to make a LinearLayout clickable and it works fine. My Adapter's getView looks as such:...............

Scenario:Three buttons enabled by on click event.
-I am using sliding drawer... on which no of buttons are there. -When sliding drawer is opened...its overlapping the preveously defined three buttons.
My problem is... when i am clicking on sliding drawer ... the below button is activated and accordingly it goes to next activity...
Means ... i expect if one view is on top of another view... the lower view should not work.
