Android :: Register Button Click And Take Action Based On Radio Selection

Sep 1, 2009

I'm trying to teach myself how to write android apps and I'm having trouble registering a button click and taking actions based on which radio button is selected at the time. This is a simple tip calculator:

import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.TextView;
import android.widget.RadioGroup;
import android.view.View;

public class TipCalc extends Activity implements RadioGroup.OnCheckedChangeListener,View.OnClickListener

Android :: Setting Selection To Last Item Also Loads First One

Jun 12, 2010

I'm developing application that shows thumbnails of images in gridview widget. I load HTML with image names, and set ImageAdapter. That image adapter loads single image (from internet or SD card) in AsyncTask with selected image position. After I initially download HTML with image names, and parse them to array, I set selection of GridView to index of last image. But, what happens is this : first image that gets downloaded is image with index zero. That gives me a lot of trouble because I'm using convert views and AsyncTasks, so sometimes I end up with wrong picture at first column in last row (sometimes picture with index 0 gets in there), depending on which AsyncTask gets executed first. Even stranger, I end up with around 10 calls to getView for image with index 0.Does anyone have idea how to switch GridViews position to last image, and not have image with index 0 loading?

Android : Detect Selection Of An Already Selected Item?

Apr 18, 2010

I have an activity with a ListView check list and a spinner that controls the sort order of the items in that check list. One of the sort options is to move the checked items to the beginning of the list. I would like to allow users to check some items in the list, select the 'sort by checks' option, check some more items in the list, and select the 'sort by checks' option again. However, I don't see how to detect that second selection of the spinner's 'sort by checks' option.

I've tried using setOnItemSelectedListener, but it doesn't call the onItemSelected handler unless a different item is selected. And I've tried using setOnItemClickListener, but it seems that listener cannot be used with a spinner according to following run-time exception from logcat:

- - - D/AndroidRuntime( 987): Shutting down VM W/dalvikvm( 987): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) E/AndroidRuntime( 987): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 987): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.spinner/com.test.spinner.check_list}: java.lang.RuntimeException: setOnItemClickListener cannot be used with a spinner. E/AndroidRuntime( 987): at 2268) - - -

Any tips on how to detect the selection of an already selected item in a spinner?

Android :: Bluetooth.a2dp.intent.­action.SINK STATE CHANGED

Jan 10, 2010

im currently looking for the way that my app knows when the phone has being paired and connected to a bluetooth headset device.

I read something about this intent, but not on the Reference documentation of


Is this actually working, is it officially supported.

I mean, can we just register a broadcastreceiver to handle this intent , check for the EXTRA_STATE string extra to see if it equals STATE_CONNECTED and be sure that the phone is now connected with a bluetooth headset device ?

What about this BluetoothA2dpService class? There is no official documentation about this, everything i found i from code snippets of the android OS source code.

Android : Tell Is Someone Has Pressed A SPINNER But Not Changed Visible Item In It?

Jun 6, 2010

I have a spinner, which mostly works. If a user selects one of the items in it, the 'onItemSelected' routine catches it just fine.

But if a user clicks the same spinner, but does not change from the already visible item that it's currently displaying, the 'onItemSelected' routine just ignores it, and the logs show:-

WARN/InputManagerService(577): Window already focused, ignoring focus gain of:$Stub$Proxy@437948b0

I there anyway to capture someone doing this? The idea is that my spinner contains a list of names, and when a user selects one from the spinner, it gets added to a listview.

I could just add another button to get the name from the spinner, but, screen-space is already lacking and I'd rather not add anymore content.

General :: Draw XML Upon Selection Of Item In Dropdownlist Array?

Aug 25, 2012

With spinner, I am able to create a dropdownlist menu. (As seen from the code below)


// Set up the action bar.
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_M ODE_LIST);


However, how should i make it draw a XML upon selection of the item in the dropdownlist's array? Or should i just change everything to popup menu and onclicklistner instead of spinner.

Android :: Get User Selection And Convert It To A String

May 5, 2010

I just got a Droid, and after having used it for a while, I felt like I wanted to make a program for it. The program that I am trying to make calculates the actual storage capacity of secondary storage mediums. The user select from a list of units that ranges from KB to YB and the size the entered gets put into a formula depending on the chosen unit.However, there is a bit of a problem with the program.From my testing,I have narrowed it down to the fact that the user's selection is not really being obtained from the spinner.Everything I look up seems to point me to a method quite similar to how it works in J2SE, but it does nothing. How am I actually supposed to get that data?

Android :: Storing A User Selection That Stores Itself For Use On Reload In App

Aug 2, 2010

I've built a dialog that asks the user to pick a city from the list provided when the application first opens. The dialog works perfectly, however I want to store the user's choice so that when the app is opened a second time, it checks to see if the user has already made a selection previously. If they have, it doesn't display the dialog and defines the city variable as their previously chosen preference. And obviously, if they haven't made a selection previously (because its their first time opening the app or for some reason the app couldn't read the stored preference), it displays the dialog.

Android :: Spinner Control - Differentiating Between User Selection And Initialization

Jun 12, 2009

I've implemented a spinner with an OnItemSelectedListener event handler. When I initialize the spinner and when a user makes a selection the even handler gets called. What I need is to determine when a user makes a selection. Is there a way to determine in the OnItemSelectedListener whether the event was triggered because of data initialization, or because of a user selection? Am I going down the wrong path trying to do this with the OnItemSelectedListener? Is there a better way to to capture a user selection event on a spinner control?

Android : User Action Emulate Hardware 'Back' Button?

Sep 6, 2010

I looked around and although there are many related questions I didn't see one that answers my exact question:

I would like to create an app that runs in the background that provides the exact same functionality as the hard coded 'Back' button in all cases.

The reason? I (for example) have a Droid X, and it is BIG. it makes it extremely hard to use one-handed and having a swipe gesture function as a back button (like in Palm Pre for example) would greatly increase the ease of use.

as far as I'm concerned the app could just be one simple class that contains:
1) a listener for the 'back' swipe
2) a call to the physical hard button itself

Is this possible? are there built in APIs for the hard coded buttons that would allow me to call them without actually pressing them?

Again - I'm not interested in overriding the button, I'm interested in making a software call to it - or failing that, in emulating it's behavior in any and all states and other apps!

Please forgive the naivete of this post. I am a very novice programmer and really I just want to know whether this is possible before I start to devote myself to trying to build it.

Android :: ListView Selection - Make Only Item Click Be Effected By Click?

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?

ListView lv = (ListView) findViewById(;
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {

Android :: Spinner - Don't Display Selection / Set Selection Text Color As Transparent?

Aug 4, 2009

I'm trying to use Spinner as a button with selection pop-up. Basically I want an icon and when user clicks it - the popup list is displayed and user can make a selection. The Spinner happily accepts icon image as drawable background. Unfortunately when I select a value the text overlays the background. Is it possible to set selection text color as a transparent? Or maybe there's a better way?

Android :: Way To Present List To User Where Each Item On List Starts An Activity When Selected

I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...
