Unused Parameter In OnClick Method

Nov 18, 2013

I did was use the search function and after 10 pages I could not see what I was looking for. In java, we use method parameters for a number of reasons but I've never used parameters in my methods unless I needed them..When defining a method in android for a button that I want to click, I had my method defined in XML under the Button element

[HIGH]androidnClick="showText"[/HIGH]
then, in my ProjectName.java file I defined the method
[HIGH]public void showText(View view){
}[/HIGH]

I was told that the View in the parameter is the view that was clicked.Button is a subclass of View as is TextView and since that is the case,is this the rule for just the onClick method? Also, why can I not pass the Button as a parameter? Button is the actual "View" being clicked, so why not Button?

Furthermore, are there other methods similar to this and if so, do they all follow the rule just like the View parameter, where let's say if I had a class called "A" and it had a subclass "B" and that class had a subclass "C", and if I wanted to use the onClick method, I can only pass the Highest Class as the parameter?

To simplify that, are there ever cases where I would pass anything else OTHER THAN "View" as the parameter to these methods?

Android :: Project Using Httpclient - Http.client - Apache - Post/get Method

May 17, 2009

I'm doing a Get and Post method for an android project and I need to "translate" HttpClient 3.x to HttpClient 4.x (using by android).

My problem is that I'm not sure of what I have done and I don't find the "translation" of some methods...

This is the HttpClient 3.x I have done and (-->) the HttpClient 4.x "translation" if I have found it (Only parties who ask me problems) :

CODE:...........

I don't know if that is correct. This has caused problems because the packages are not named similarly, and some methods too. I just need documentation (I haven't found) and little help.

Android :: Project Contains Errors - Eclipse Won't Compile Project

Mar 21, 2010

Somethings I'll have an? .xml file selected when I compile a project, only to have a? .out.xml generated. Deleting the file doesn't clear the error, and Eclipse won't compile the project. It just reports that your project contains errors. The solution is to go to Project/Clean. This will clear the error in the project and allow it to compile.

Android :: Get Project And Std Java Project To Play Nice?

Aug 11, 2010

I can now get our Android project to talk to our non-Android project. But there's still an issue: I are trying to have an Android class call a non Android Hello World class. I tried compiling our non-Android Hello World class in a separate Eclipse workspace. I then packaged it into a jar. I imported that jar into our Android Hello World class.

I then called one of the methods in the non-Android Hello World class. When I ran the Android Hello World class as an Android application, the following runtime error occurred. Here are the Android debug logs:

08-11 09:07:56.764: ERROR/AndroidRuntime(333): FATAL EXCEPTION: main

Android :: Reference Project Library From Another Project

Jun 6, 2010

I have 2 android projects out of which I modified one to work as a library. I want the main project to refer to this library to perform few functions. While this scenario works just as expected, I want to introduce one more functionality. I want to link this library project with another just a java project which has code common to both Android and Blackberry applications. This second part however doesn't seem to work and throws "The application <appname> (<package name>) has stopped unexpectedly. Please try again" with a ForceClose button. I would greatly appreciate if someone can give a brief information on how to make this work.

Android :: R.java File From Android Library Project Not Importing Into Application Project

Aug 8, 2010

I followed the instructions here on how to create an Android library project, and use it in an Android application:

http://developer.android.com/guide/developing/eclipse-adt.html

But it is not working. I can see the library project is added to my application but I cannot reference anything in it because it won't build. The R.java file from the lib is NOT being added to my application project, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file.

I don't know if this has anything to do with it, but in the console there are messages stating that the there is "No resource identifier found for attribute 'X' in package 'Lib Package'. My library package has a a few styleable attributes defined for a custom view I made, all of which are being complained about in this console message. The library builds just fine, and I don't get those messages in the console until I hook the library to my application, so I don't know what's up with this.

Android :: Show Method Definition - Eclipse Recognizes Warning On Method

Nov 22, 2010

In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

Android :: How Can A Code In Library Project Call Code In App Project?

Oct 8, 2010

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...

Android :: OnClick To Run Application On 1.5?

Nov 26, 2009

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]

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.

Android :: Open New View By Onclick

Jun 28, 2010

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);}

Android :: Implement OnClick For DialogPreference?

Sep 1, 2009

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); ....................

Android :: Imageview OnClick Animation

Feb 16, 2010

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...

Android :: OnClick Won't Fire On ImageView?

Aug 5, 2010

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:

Activity:

CODE:........

Layout:

CODE:............................
