I have a Tabbed View that displays a list in different tabs. When I click on the currently active tab (not the displayed view) I want to do something. Currently - the OnClickListener is NOT called. the OnTabChanged Listener however seems is working fine. Am I registering on the wrong View?

I am trying to get the Click - event when clicking on the currently selected tab of my TabActivity. The onTabChangedHandler is only called whenever the tab is changed, not if the currently active Tab is clicked. The debugger tells me i have the onClickListener Registered for the TabWidget within my TabHost.

Has anyone had trouble getting android projects to work on Mac OSX? I took a project that I run on a Windows Vista system and checked out the project on my Mac OSX box and it can't recognize OnClickListener.
I did the same thing on my Ubuntu dev box and it works no problem. Same version of Eclipse (3.4.1) and android plugin 0.8.0v200809220836-110569
Create an anonymous implementation of OnClickListener
private OnClickListener mCorkyListener = new OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked}};
I am trying to do something similar to that of the android lock screen pattern. I have a class that extends a view that I create multiple instances of. These appear on the screen all at once.
I need to be able to click on them individually and have each one turn green individually, however only one on touch listener is listening at once and it belongs to the last dot which appeared, so if I click anywhere on the screen the last appeared dot turns green no matter where I click.
Here is the code for my dot class:

In the code I called newdotdraw multiple times.
On a picture I need to do two differents behaviours when user click on it or slide on it.
The management of the touch event (slide) is done on a parent view. So I put setOnTouchListener on my imageview and implement ACTION_MOVE to dispatch the event to its parent.
To manage the click event, I put a setOnClickListener on my image but the event was not catched. With debug, I understand that the ACTION_MOVE was still called and the onClick event was forgotten by the onTouchListener.
I decided to try to catch the event ACTION_UP on onTouch event...
Finally, I can set only ONE event and not the both. If I can click, I can't slide and if I can slide, I can't click....
I have a grid view of buttons that is generated by a CursorAdapter. When the CursorAdapter is passed to the Gridview the view renders correctly however the first item in the grid does not fire the OnClickListener event.
If I select another button in the grid, the event fires correctly however if I selected the first button then another button, it loads the first button action then the section button action.
When testing this, it only seems to be an issue in Android 2.2 on my emulator, my 1.5 phone works as expected. I've wiped the emulator but that doesn't seem to have made a difference.

I am writing an application which one of the activity has a button and use this button to switch to another activity when clicking that.
The main activity implements the onCreate and OnClickListener as follows:

When I try to run this program on my emulator, after hitting the button, the program stopped unexpectedly. I follow the instructions of implementing OnClickListener firmly so I don't know what's the problem in my implementation.
Im trying to get an onClickListener to fire on a Spinner, but i get the following error: Java.lang.RuntimeException is "Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead," the thing is, im sure I want to call onClickListener and NOT onItemClickListener. I found this question asked by someone else on stackOverflow.
The question is here: link text
The answer stated there is:
You will have to set the Click listener on the underlying view(normally a TextView with id:
Android.R.id.text1) of the spinner. To do so:
Create a custom Spinner In the constructor (with attributes) create the spinner by supplying the layout android.R.layout.simple_spinner_item Do a findViewById(android.R.id.text1)to get the TextView Now set the
onClickListener to the TextView
I have tried the answer noted there, but it doesnt seem to work, I get a null pointer to the TextView after I do the findViewById().
This is what im doing:
CODE:.......
layoutspinner.xml

I'm new to stack overflow, I didnt find any way to post an aditional question to the other thread (or comment since I have to little rep) so I started a new question.

I have a list view with 2 buttons on each row. I am using a cursoradpater to populate the list. I am also using the view holder pattern on newview() bindview().
My questions are: where do i put the clicklisteners for the buttons knowing that the action for the button is different from the action of the list item itself? Do i keep the onListItemClick ?
I am working with a library of maps which paints the icons on the map using drawables and canvas. Now, i'm trying to modify it in order to the user can click on icons. So i want to attach drawables into different ImageView with a onClickListener. However, i don't know how i can paint the ImageView using canvas from method onDraw.
I've tried with:
ImageView iv = new ImageView(context);
iv.setDrawableResource(drawable);
iv.draw(c)
But it doesn't appears in screen.

I have created a parent class and a child class that inherits from it. When I set the OnClickListener in the child class, the event fires when the button is clicked. When I move the set OnClickListener to the parent class, the event doesn't fire. I've got to be missing something obvious but I just don't see it.

Is it possible to have the android load up another UI from a different class through a Onclicklistener? What I mean is that if I have two UI classes (c1 using m1.xml and c2 using m2.xml). Is there a way to load the c2 UI though the onlicklistener set on a button?
When I w programming in Java i usually add an actionlistener to the button and create a new instance of c2 in that actionlistener. That doesn't seem to work here, and so I was wondering if theres another way to do this?
I am writing an Android Application which outputs some array of buttons dynamically.
My question is how to implement onClickListener() functionality for Array Of Buttons. I mean how to recognize the button that is clicked in public void onClick() method ? I need to display a toast based on the button that is clicked.
I have a listView using a custom adapter. Each row contains a button and some other Views. I want to be able to click either on the button, or on the row itself (to edit the item of the list that is clicked).
Setting an onItemClickListener in the activity won't work because of this problem
I think I have to set an onClickListener in the getView() method of my adapter for it to work properly.
I would like to use my activity's onClickListener, in order to use a startActivityForResult() when the row is clicked, in order to have something returned to my activity when the item edition activity is over.
How can I do that?
Please find the code sample below:
public class Abc extends Activity implements OnClickListener{
private ListView displayList;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainlayout);
displayList =(ListView)findViewById(R.id.addressbooklistview);
addressbookAdapter = new CustomListAdapter(this,addressbookList);
displayList.setAdapter(addressbookAdapter);
registerForContextMenu(displayList);}
I am not able to invoke the context menu on long press. Please let me know any solution for the same.
I'm starting with Scala + Android (and using the sbt android plugin). I'm trying to wire a button action to a button without the activity implementing View.OnClickListener.
The button click fails at runtime because the method cannot be found. The document I'm working through says that I need only declare a public void method taking a View on the action, and use that method name in the layout.

I'm Computer Engineering student having my internship and my boss assigned me to make an android application for Basketball Scoreboard which I'm having a hard time for I don't have lot of Java courses.
As of now,I'm confused on how to change the value of the TextView by onclicklistener. And a timer which upon clicking the textview of timer, it will start to count down from e.g. 10 minutes and to pause the timer, clicking the timer's textview again.
My java code looks like this:
package com;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
//import android.widget.TextView;
//import android.widget.TextView;
import app.scoreboard.R;
//import app.scoreboard.R.id;

I created a TabActivity with contains 3 tabs. Each tab's content sets different Intents.I would like to add a "footer" wich will appear on each tab. So I get TabActivity's FrameLayout and add it my footer view.Is it possbile to define where place the footer (with an attribute like AT_BOTTOM)? So contentTab dimensions are calculated according to this footer.

I would've tried to send a screenshot for this query if I could, but i'll try and explain.
I have 3 Tabs, each showing a separate Activity. Underneath those tabs (and above the activity display), I want to display a header. This header would probably be a Layout of some sort with a TextView inside it and a background 9patch.
Is this possible, if so how?
I am having a problem.I want to explain in detail. 1)I am Having an TabActivity with 5 tabs. I loaded content as follows.
CODE:............
And the Problem is If i want to start activity which is not specified in tabhost in above Java code,it is going out of tabactivity. ie.,It is not coming in tabactivity.
2)But i want to have all the activities under tabActivity.
I create a TabActivity from Several ListActivities.
The lists are created from a cursor load in a AsyncQueryHandler. I have got no problem to load the content of the list.
After that I run an insert in the AsyncQueryHandler, and I meet the following error. The insert is done by the listActivity.
If I run my listActivity individually and that I do my insert, everything is find. Do know why ?

I'm having some difficulties getting the TabActivity to work.
Here's the implementation of the class:
CODE:..........
The problem is that I call this class from my main activity (which is a MapActivity if it matters) and when I do the TabActivity doesn't show. It registers the click on the option menu and it even starts the intent but the screen doesn't change..it just stays on the main activity and i see in the logs that the main activity gets resumed.
I call it like this:
CODE:...............
Like I said...there are no errors (the classes called from the tabs exist of course), just no actions. I put some log commands into the onCreate function in the tabactivity (as you see) and they all get written into the log...I have no idea what I'm doing wrong here.
I'm working on Android v1.5. I want to use a TabActivity with 6 or 7 or more tabs. However, I do not want to clutter my screen with so many tabs together. Hence, I'd like to be able to show, say, 3 tabs on the screen, and to be able to scroll to the other tabs. How may I achieve this? I could not find any example for this by Googling.

View 1 Replies View RelatedI have a TabActivity based class which has 3 tabs. All are ListActivities (but that's not important for this problem)
I'm updating the TabHost's TabSpec's to change the text on the tabs. This works fine and the ListActivities display correctly.
Iater on the execution flow I need to update the Text on the tabs from "Current Text" to "Current Text (3)", for example. I update the TabSpec.setIndicator() with the new text, and attempt to call invalidate() on the TabWidget (and all it's children). But the tab text refuses to update!
I have been trying to reuse the tutorial on the Android developer website about developing a TabActivity App but, unfortunately, it never worked, even when I constructed it the exact same way as it is described...
Using the debugger it seemed the problem came from the main layout.
