[android-developers] Re: No callback when list item is touched.
I do have that listener defined as well. Though again, I'm not getting a
callback when I touch it. I do get a call back when selecting an item with
the trackball.
list.setOnItemSelectedListener(new
AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView? arg0, View arg1,
int position, long id) {
Log.v(this.toString(), Item Selected);
viewItem(id);
}
public void onNothingSelected(AdapterView? arg0) {
// TODO Auto-generated method stub
Log.v(this.toString(), Nothing Selected);

touch, by turning orange for that moment.
Here is how I've setup the listener. This is within an Activity, not
a ListActivity.
list.setOnItemClickListener(new
AdapterView.OnItemClickListener() {
public void
onItemClick(AdapterView? arg0, View arg1,
int position, long
id) {
viewItem(id);
}
});
What am I missing? Is there another listener I need to configure?
You need to call setOnItemSelectedListener() to handle taps like that.

[android-developers] Re: No callback when list item is touched.
No, I am printing a log entry just before I call viewItem(), and I wasn't seeing that log statement when touching the item. Though I think I have found the problem. I narrowed it down to my custom adapter that extends ArrayAdapter. In my adapter I call the overloaded ArrayAdapter constructor: public ArrayAdapter(Contexthttp://code.google.com/android/reference/android/content/Context.htmlcontext, int resource, int textViewResourceId, List http://code.google.com/android/reference/java/util/List.htmlT objects) I use this so I can define a standalone XML layout (resource) to use for each item in the list. Then when overriding getView(), I call super.getView() to get that layout, set the elements based on the object at that position, then return the layout for that row. The problem occurs when my layout contains a Button or ButtonView element. After taking out the Button (which I wanted for a speficic action to be taken), the listener is now getting a callback when touching the item. Is this a bug or am I not doing something correctly? Below is an XML layout for my rows. Simply commenting out the Button element fixed the problem. ?xml version=1.0 encoding=utf-8? LinearLayout xmlns:android=http://schemas.android.com/apk/res/android; android:layout_height=60px android:orientation=horizontal android:id=@+id/row_id android:layout_width=fill_parent ImageView android:id=@+id/row_icon android:layout_height=wrap_content android:layout_width=wrap_content android:layout_gravity=center_vertical/ LinearLayout android:layout_height=60px android:orientation=vertical android:id=@+id/row_text android:layout_width=wrap_content android:layout_weight=1 TextView android:id=@+id/test_row_text android:layout_height=wrap_content android:textColor=#FF android:textSize=14px android:layout_weight=1 android:layout_width=wrap_content/ TextView android:id=@+id/test_row_desc android:layout_height=wrap_content android:textColor=#FF android:textSize=14px android:layout_weight=1 android:layout_width=wrap_content/ Button android:id=@+id/test_row_action_button android:text=@string/add android:layout_width=wrap_content android:layout_height=wrap_content android:layout_gravity=center_vertical/ /LinearLayout On Sun, Feb 1, 2009 at 2:41 PM, Mark Murphy mmur...@commonsware.com wrote: Brendon Drew wrote: I do have that listener defined as well.

Trackball/D-pad movement is select, tap is click. Without more code, I can't give you a solid answer. What you're doing sure looks good. Are you sure the issue isn't something inside of viewItem() -- that you're getting the event but viewItem() isn't responding to it properly in the click case? -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Published! -- Brendon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

the button had neither focusable or clickable defined. and why was I getting the event when clicking with the trackball, but not when touching it.

[android-developers] Re: Orientation sensor gone bad?
Maybe download the Bubble app from the market, see if its really the sensor as opposed to a bug in your code. Sent from my gPhone On Nov 7, 2008 12:20 PM, kelly [EMAIL PROTECTED] wrote: Hello, Has anyone noticed trouble with the orientation sensor in their phone? Mine was returning values as described in the Android documentation until about 12am last night. Up till then, holding the device in a vertical orientation, the pitch value was -90 degrees, upside down was +90 degrees, and so on. Since that time, the sensor doesn't seem to be working correctly. Now it reads -20 in an upright position and 20 in an upside-down position. Is there a way to reset the phone (or at least the orientation sensors) so it works correctly again? I have several applications now that don't work right because of this.

Well, it's not available to the user directly, but it is used by the system as a whole. I'm simply curious how to determine total physical RAM.
