Android :: Possible To Have Droid Load Up Another UI From Different Class Through Onclicklistener?

Feb 11, 2009

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?

Android :: OnClickListener Not Firing From Parent Class

Aug 17, 2010

A Follow up to this question: http://stackoverflow.com/questions/3488880/group-of-views-controls-on-multiple-screens

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.

Android : Way To Load Dynamic Class?

Nov 2, 2010

Is it possible to dynamically load classes from a URL into your application in the same way as a desktop application can? For example, can you do a simple boot-strap application which you install onto the device, that boots up loads the main jars required for the applications from a server, or from a local jar on the SD for example?

Android :: Way I Can Load Class Based On SDK Version?

Jun 7, 2010

Is there any way I can load a class based on what version of the OS the phone is running? For example:

I made an app which requires 1.6+ Android. Is there a way for me to load one class or the other based on what OS the phone is running? I'm asking this specifically for contacts. The database was changed from 1.6 to 2.0 and the old version doesn't retrieve contacts on the new OS phone. I'd still like to keep my 1.6 requirement, but at the same time I'd like 2.0+ phones to access the contact part of the app.

So can I make 2 APIs, somehow pack them with the app and decide on the fly which I choose to import?

Android :: Implementing An OnClickListener?

Nov 9, 2010

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:

CODE:......

In the code I called newdotdraw multiple times.

Android :: OnTouchListener & OnClickListener ?

Apr 16, 2009

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....

Android :: OnClickListener Not Firing In GridView - 2.2 Only

Aug 8, 2010

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.

Android :: Setting A Spinner OnClickListener()

Oct 13, 2010

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

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

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:

CODE:........

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.

Android :: ListView - Use The Activity OnClickListener From A Custom Adapter?

Nov 1, 2010

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?

Android :: Load Single App During Load And Not Allowing The User To Step Out Of It

Oct 22, 2010

I have been assigned the task to use an android tablet to run a single app in an enterprise setting. Ideally, when one switches on the tablet this app should be loaded perhaps during startup and the user need not step out of this app. The app logic itself is rather easy but I am wondering if it is at all possible to load a single app during load and not allowing the user to step out of it.

Android :: Communicating Between Receiver Class And An Activity Class

Jul 14, 2010

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

Android : Wire A Button Action Without Activity Implementing View.OnClickListener

May 11, 2010

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.

What have I done wrong? MainActivity.scala package net.badgerhunt.hwa

import android.app.Activity
import android.os.Bundle
import android.widget.Button
import android.view.View
import java.util.Date. Code...

Android :: Possible To Load A Layout XML At Runtime And Load Into Activity?

Sep 4, 2010

Is it possible to load a layout XML at runtime and load into activity?

In my app, I have various types of data like Person, Company, City, etc; The requirement is to dynamically load the layout, find views by tags (property names like Person.name, Person.address) and then fill in data. For example, if user has selected an object of type Company, we want to load a company.xml layout, inflate it and then associate various properties (company name, company slogan, city, address, revenue) to tagged views. One possibility I see here is - each view in the layout will be associated with property-name as tag and then appropriate data will be loaded in appropriate views.

What should be the best design you would recommend?
