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 question about implementing OnClickListeners for developing with the ADT. I'm unsure of which way is more efficient, can anyone please provide me with pro's and con's of each approach?

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
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 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.
View 5 Replies View RelatedI 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 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:
CODE:...........
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.
Per recomendation I tried this:

But logCat isnt showing promising results.
10-14 16:09:08.127: INFO/System.out(3116): Count =7
10-14 16:09:08.127: INFO/System.out(3116): ChildCount =0
I have tested this on API levels 7 and 8 with same results.
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 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 have run mediaplayer in SDK which can play media in res/raw folder successfully on emulator , but now I wanted to run it on my hardware which have already successfully implemented the android kernal and file system and audio, video drivers etc. I have no experience to implement JAVA app . I once implemented mplayer app written in C to my linux OS which only need to copy the final executable file , but now I don't know which files or folder should I copy to my platform because I have no basic knowledge of Java although I have run successfully on my emulator.
View 5 Replies View RelatedI've been playing around with the new LVL announced yesterday and wanted to write a policy which only stops the user when it is certain that he does not have a license. In other words, the policy will only "dontAllow" the user if the last meaningful response from the licensing service was NOT_LICENSED. Therefore, if the user is offline when they first use the app, then they will be allowed in. The idea behind this is that I don't want genuine paying users to ever (within reason) be inconvenienced by this licensing system. The downside is that all the user needs to do is clear the app data and go offline before restarting the app. The app will continue working until they go online (and restart the app). My thoughts are: 1. Most users won't know about that workaround 2. Those users that are happy to use that workaround, probably wouldn't pay for the app anyway.
View 6 Replies View RelatedI'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.

We have discovered a potential bug in the implementation of AppWidgets. Here is a simple reproducer.
Attached is the code for an application containing a TestActivity and a TestWidget. TestActivity extends MapActivity and TestWidget is a simple widget provider which updates a TextView every 2 seconds. Now if the TestActivity is launched with no instance of TestWidget running, it works just fine. But if the TestActivity is launched after placing the TestWidget on the home, it results in ClassNotFoundException. Here is what we get:
CODE:.............
So it seems we have an inconsistency in the way the class loader works for the same apk.
WORKS - Launch the application by itself, without invoking the Widget. DOES NOT WORK - Create a Widget on the Home screen and then launch the application from the launcher.
The source code for this application (http://www.yousendit.com/ download/TzY3ZGVhZy96NE4zZUE9PQ) has been attached. Hope someone from the Android team can shed light on this behavior.
This error is seen on the 1.5r3 SDK. Not sure if this has been addressed in 1.6 and 2.0 SDKs..

What might I use to fingerprint a phone for license verification?
As an aside, how have your experiences with LVL been so far? Any pitfalls? I'm not asking for anyone to share their implementation details as that would give the hackers ideas.
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;

View 1 Replies View RelatedI would like to implement the similar widget as QuickContactBadge from which I can launch some internal activities. I checked out the source code for QuickContactBadge, QuickContactActivity etc and simplified them to accommodate our requests. It can launch and display at correct position. However, I can not see the original view below the quick contact tack no matter how I try. And I found the window created by QuickContactWindow is quite small and I tried to set the background etc. Nothing works. Who can help or give some guidance about how window works? Say, from Activity A, I click on image, I launch a new activity (or window), how can I make the Window of Activity A is still visible? Or more general, what is the best way to achieve similar behavior like QuickContactBadge?
