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.

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.

View 8 Replies View RelatedThe layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

View 1 Replies View Relatedjust 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 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

// 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 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 two onclick method in android project
CODE:...............
And i have onther onClick method in which i have to call that method directly
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.

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 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?
