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 :: Setting Values And Display Text In Android Spinner

May 31, 2010

I need help in setting up value and display text in spinner. As per now I am populating my spinner by array adapter e.g. mySpinner.setAdapter(myAdapter);

And as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. Now in my case I want to make spinner like the drop down box, which we have in .NET. Which holds a text and value. Where as text is displayed and value is at back end. So if I change drop down box , I can either use its selected text or value. But its not happening in android spinner case.

For Example:

Text Value
Cat 10
Mountain 5
Stone 9
Fish 14
River 13
Loin 17

So from above array I am only displaying non-living objects text, and what I want is that when user select them I get there value i.e. like when Mountain selected I get 5. I hope this example made my question a bit more clear.

Android :: Spinner Widgets Look Different On Different Devices - Can Define Own Spinner That Looks Same On All Handsets

May 20, 2010

I use this code to generate a spinner in my app:
code:.........

On my device (Motorola Milestone) and in the emulator this looks like the standard gray spinner widget.
On of my colleagues uses a Motorola Backflip and on his device the Spinner is black. Now its very hard to read the font in the spinner.

What do I have to do to use my own view for the spinner? I don't mind to have the gray spinner on all devices, but it should always look the same on all devices.

Android :: Call Spinner's Value - Use Other Values Based On A Spinner's Value

Jan 25, 2010

I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?

Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028

My other inputs are EditText views, so right now I am set up like this:

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

That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'

Android :: Popup List Like Spinner Without Spinner

Jan 25, 2010

I have a spinner widget in my activity which lets users pick a list name.

Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on.

This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner, without using the spinner itself.

Is there any way I can do this?

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 :: 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 :: 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 : 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

Nov 23, 2011

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;

[code].....

I'm using Android 3.2 (emulated).
