Android :: Spinner Display The Radio Button In Textview?
Oct 27, 2010
i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.
here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.
Here are the appropriate code snippet... couple of points:
This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.
Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

I am trying to populate a TextView based on the current selected options in 3 Spinner(s) but cant seem to figure out how to retrieve the selected values from the Spinners to invoke the update function with.
Here is my current code (quite messy but I'm just learning Java,
public class AgeFun extends Activity {
private String[] dayNames;
private String[] yearArray;
private final static int START_YEAR = 1990;
private static TextView textDisp;
private Button calcButton;
private static Spinner spinnerDay, spinnerYear, spinnerMonth;
private static ArrayAdapter<?> monthAdapter, dayAdapter, yearAdapter;
private int year, month, day;
/** Called when the activity is first created. */
@Overridepublic void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
year = 2000;
month = 1;
day = 1;
textDisp = (TextView) findViewById(R.id.textView1);
calcButton = (Button) findViewById(R.id.button);
calcButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
AgeFun.updateAge(year, month, day);
// Month spinner
spinnerMonth = (Spinner) findViewById(R.id.spinnerFirst);
monthAdapter = ArrayAdapter.createFromResource(
this, R.array.monthList, android.R.layout.simple_spinner_item);
monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerMonth.setAdapter(monthAdapter);
// Day spinner
dayNames = new String[31];
for(int i =1; i <= 31; ++i)
{ dayNames[i-1] = Integer.toString(i);
} spinnerDay = (Spinner) findViewById(R.id.spinnerSecond);
dayAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, dayNames);
spinnerDay.setAdapter(dayAdapter);
// Year spinner
yearArray = new String[40];
for(int i =0; i < 40; ++i)
{ yearArray[i] = Integer.toString(START_YEAR+i);
} spinnerYear = (Spinner) findViewById(R.id.spinnerThird);
yearAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, yearArray);
spinnerYear.setAdapter(yearAdapter);
updateAge(2000,1,1);
}private static void updateAge(int year, int month, int day) {
Date dob = new GregorianCalendar(year, month, day).getTime();
Date currDate = new Date();
long age = (currDate.getTime() - dob.getTime()) / (1000 * 60 * 60 * 24) / 365;
textDisp.setText("Your are " + Long.toString(age) + " years old");

I am wanting to allow the user of my android application the ability to set some parameters. The radio button is ideal for this situation. However, I don't like the radio buttons are rendered. Is it possible to change the radio button icon? For example, is it possible to create a custom layout for each row and in that layout reference my own icon and change the font et al.

I have a Spinner with an ArrayAdapter that feeds Values into it. The layout for this views looks something like this:
CODE:.................
The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot:
I tried to pass the Id of my own TextView into the Adapter but everytime the spinner should be shown I get an Exception that the Id I supplied is not valid:
CODE:........................
Where do I have to define the TextView? In a separate xml file? With a surrounding viewgroup?
It would help me a lot if I could see an example of the adapter initialization and the textview definition?

For an Android application, I'm trying to use a Spinner which, when an option is selected, will hide/display relevant View objects. For my application, these objects are an EditText and an associated TextView label for the field. Unfortunately, I can't seem to get the EditText to hide/display, and when I add it code to hide/display the TextView, I get a NullPointerException. I presume that since I am laying out the view objects in a RelativeLayout, by hiding one of the view objects, I am removing its relationship with other view objects, hence the NullPointer.
Can anyone figure out why this might be happening? Here's my code...

As the title says, i have a Spinner with just a couple of options and a button. I didnt declared any Listener for the spinner, instead of that, what i want is use the button and perform different actions depending on the spinner selected option.
So, i declared a handler in the button option "android:onClick", but once there, i dont know how to access the option selected in the Spinner.

Has anyone seen a a onItemSelected not being called when using a spinner inside a listviewActivity. I have the code below Inside a listViewActivity. The spinner is shown on screen by pressing a button (not the spinner) which in turn calls performClick() on the spinner. When I select an item from the spinner the onItemSelected function is not called. Does anyone know why this might be? Code...

I am working on an Android application that displays a list of items when a tab is selected, then displays detail information about an item that was selected from the list :
CODE:............
The details are to be displayed using ImageViews, ImageButtons, and TextViews. The data comes from a database query, so the TextView text and ImageView drawables have to be assigned dynamically.
The correct text from the database query gets assigned to each of the Views. I can see everything being added when I step through the code in the onCreate method of Activity3 in the debugger.
BUT, the drawables are only displayed when I select the first item in the ListActivity. If I select another item, all TextViews display the correct information but the drawables are not displayed for the ImageViews or ImageButtons. It looks like only the backgrounds are being displayed.
The ImageButton drawables are not being dynamically assigned, only the ImageView drawables are. The ImageButton drawables are set in the TableLayout XML that is associated with the activity. Here is one entry :
CODE:..............
Originally, I had android_drawable="@drawable/ic_phone", then tried adding android:background="@drawable/ic_phone", and finally created the following selector (phoneselector.xml) :
If I select the first item again, its proper ImageView drawables are displayed along with the proper text in the TextViews. The ImageView drawables that belong to the other items have no problems being displayed in Activity2's ListView.
The code successfully sets an onClickListener for the button (also in Activity3.onCreate). If I click on what is displayed on the spot where the drawable should be, the phone number is dialed.
The code successfully sets an onClickListener for the button (also in DetailActivity.onCreate).
Has anyone seen anything like this before? I would appreciate any help figuring out what is wrong.
Here are more details because I wonder if the problem has to do with the use of the Views :
The Activity1 extends TabActivity and sets a TabHost view that contains a FrameLayout along with the TabWidget. Activity1 creates the tabs dynamically.
Activity2 extends ListActivity and sets the content to its ListView (via setContentView(getListView()).
When ListActivity.onListItemClick is invoked (item in list is selected), a new Intent is created that contains an identifier in a Bundle and Activity3 is started.
The started activity (in Activity3.onCreate...) sets the content to a TableLayout view defined in a .xml file (via setContentView(R.layout.details.xml).
Here is the code from Activity3.onCreate :
CODE:.................

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.
