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 android.app.ActivityThread.performLaunchActivity(ActivityThread.java: 2268) - - -
Any tips on how to detect the selection of an already selected item in a spinner?

Is there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.
Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.

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?

I am a newbie coder and new to the SDK. I was just playing around with an app that i made. I wanted to know as to how to retrieve the item id of the selected item from the spinner when the spinner is re- populated.
For example, I created 2 spinners, if you selected item 0 from spinner1 then spinner2 will have a bunch of items and if you selected item 1 from spinner1 then spinner2 will have a different set of items. Now, my question is that when i select item 1 from spinner 1 then the items in spinner2 dont have different ids. So how do i differentiate from the two sets of data?
To illustrate,
User selected item 0 in spinner1 -> spinner2 gets data from array1 -> item 0 in spinner2 has id '0' and item text is "apple"
User selected item 1 in spinner1 -> spinner2 gets data from array2 -> item 0 in spinner2 has id '0' and item text is "oranges"
I know this sounds confusing but i hope the right people understood it..

I am creating a context menu in separate class from the listview, because the contextmenu will be access by several listviews in different classes. Whenever I long-click the listview, contextmenu pops up, but nothing happens when the options were chosen. Tried to look at logcat message and it said something like this:
Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@43c488f8
Any idea what really causing this problem? cause it works perfectly fine if i put the contextmenu on the same class as listview.

An activity has a Button and a ListView. Initially, only the Button is visible. When the button is pressed, the ListView is displayed. When displayed, is it possible for me to show one particular item as selected/focussed?
A use case could be that suppose it is a list of language settings and when the list opens, the currently selected language must be shown as highlighted. If I know the index of the item, how to set it as focused on display?

What I am struggling to figure out is how do I style the selected item? At the moment the selected item has a ghastly orange background which, under the rounded green rectangle, gives an orange outline effect.

I have a code that will prompt user to send a message by selecting the desired application, how can I detect if the user actually have chose from the options or instead pressed Back? I tried to check if the intent returned something, but is running asyncronous so cannot be tracked. Also I have tried to run the intent with startActivityForResult, what I noticed in onActivityResult that resultCode is always 0(RESULT_CANCELED) even if user selected, or not from the chooser.

I have a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);
Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };
