Re: [android-developers] Re: ListView: responding to item clicks via a listener

2011-09-21 Thread Streets Of Boston 
Try not to do this. It will break the UI model that Android users expect on 
their phones.
However, if you really need it:

1. Modify the data items that are handled by your ListView's adapter. Add an 
field that could tell how many times a list-item has been clicked (e.g. 
numberOfClicks).

2. Handle the onItemClick(...) (or in your case 'onClick(...)') as follows:
MyDataItem item = adapter.getItem(position);
Increase the item.numberOfClicks. 
If it becomes 1: do nothing.
If it becomes 2: go to the other screen and re-set item.numberOfClicks to 0.
(Be sure to call adapter.notifyDatatSetChanged()).

3. Change the 'getView()' method of your ListView's adapter:
MyDataItem item = getItem(position);
If the corresponding's item.numberOfClicks is 1, then color the background 
of that item in a particular color (that would indicate a 'highlight').
If the corresponding's item.numberOfClicks is not 1, then make the 
background of that item transparent (android.R.color.transparent).

Re: [android-developers] Re: ListView: responding to item clicks via a listener

2011-09-20 Thread John Goche 
Hello,

I am having a slight problem with my approach. When a row is highlighted
orange and
I click on it the orange highlighting goes away. But I want it to stay as I
want taps to

1. highlight the row on the first tap
2. take to a second screen on the second tap

Is this possible?

Thanks,

John Goche

[android-developers] Re: ListView: responding to item clicks via a listener

2011-09-19 Thread John Goche 
Hello,

The solution was to attach an onItemClick listener to each list item rather
than to the
ListView itself like so:

SimpleAdapter adapter = new SimpleAdapter(this, maps,
R.layout.alarmgroups_item, from, to) {
  @Override
  public View getView(int position, View convertView, ViewGroup parent)
{
View view = super.getView(position, convertView, parent);
// view.setOnClickListener(AlarmGroupsActivity.this);
view.setOnClickListener(new OnClickListener() {

  public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), clicked,
Toast.LENGTH_SHORT).show();
  }
});
return view;

  }
};

listView.setAdapter(adapter);

 Hello,

 I am trying to respond to item clicks in a ListView which has an adapter.
 When
 the items are clicked (each item is just a LinearLayout with four
 TextViews),
 my onItemClick listener is not called even though my ListView is clickable
 and focusable. I have read the following but was no help to me:

 Anyone have any ideas?

 Thanks,
