Android :: Onclick Event Works Even On Top Of The Another View
Jun 5, 2009
I am facing some problem Like:
Scenario:Three buttons enabled by on click event.
-I am using sliding drawer... on which no of buttons are there. -When sliding drawer is opened...its overlapping the preveously defined three buttons.
My problem is... when i am clicking on sliding drawer ... the below button is activated and accordingly it goes to next activity...
Means ... i expect if one view is on top of another view... the lower view should not work.

If you want a button to provide haptic feedback (ie, the phone vibrates very briefly so you can feel that you really pushed the button), what's the standard way to do that?
It seems you can either explicitly set an onClick() event and call the vibrate() function, giving a number of milliseconds to vibrate, or you can set hapticFeedbackEnabled in the view.
The documentation seems to indicate that the latter only works for long-presses or virtual on-screen keys: http://developer.android.com/reference/android/view/View.html#performHapticFeedback(int)
If that's right, then I need to either make my button a virtual on-screen key or manually set the onClick() event.
Also, if I want the vibrating to happen immediately when the user's finger touches the button, as opposed to when their finger "releases" the button, what's the best way to accomplish that?

I have a listview managed by an adapter that is extending BaseAdapter.
In the getview function im using the convertView to set up a OnClickListener. This OnClickListener work well when I am touching the screen but if I use the trackball of the HTC Desire, I see the row flashing on the screen, but the OnClickListener is not called...
I've read the android dev guide : http://developer.android.com/guide/topics/ui/ui-events.html
and its say that I should receive a onClick event from the trackball...
Im putting here my getview code in case someone see anything strange.
CODE:..............................

android:gravity="center_vertical"
android:layout_height="wrap_content"></Button>
Then in java, I have this code:...............

This should be a simple question because I couldn't get the answer from Google . I have ListView in a LinearLayout . I need to handle the click event to allow user click on the LinearLayout to trigger some function. I try to add onClickListener to the LinearLayout , and it works only when I click outside of the ListView . How do I let the click event on ListView propagate automatically to be handled by the Listener of the LinearLayout?

I have a ListView whose rows are formatted by me. Each row has a mix of ImageView and TextView. I have also implemented my own adapter and am able to draw each row through it.
Now, I would want something like this-
User clicks on an ImageView (not anywhere else on the row, but only this ImageView should respond to clicks)
I get to know the position of the row whose ImageView was clicked.
I have tried many things for this and have wanted my code to be as efficient as possible (in terms of overkill).
Currently i can capture the click event on that particular ImageView only, but I can't know which row was clicked.
I have provided an attribute in the Row XML like this-
CODE:..................
And in my code, I have a method like this:
CODE:..............
I can get the parent row (perhaps) but am not sure how to go further from here.

I could not figure out how to implement two basic functionalities with the expandable lists: 1. The onClick for the child 2. Using linear layout for the children, so that I can have multiple clickable items in same row under the parent item
Can somebody help me with some sample code for the above?

I am trying to create a list view where each item will open up a new view and display a picture and text describing the item when said item is selected. I am working with this tutorial novice-tutorials-f8/opening-windows-i-e-webbrowser-reacting-on-clicks- t22.html?hilit=reacting%20on%20Clicks
so is there a way i can use this code to open up a new view
[code]@Override protected void onListItemClick(ListView l, View v, int position, long id){ super.onListItemClick(l, v, position, id);
// Get the item that was clicked Object o = this.getListAdapter().getItem(position); String keyword = o.toString();
// Create an VIEW intent Intent myIntent = null; // The intent will open our anddev.org-board and search for the keyword clicked. myIntent = new Intent("android.intent.action.VIEW", Uri.parse ("" + keyword + "")); // Start the activity startActivity(myIntent);}

If I want to execute the focused item on the view, I need to select focused item and press enter. Now I want to find another way to execute it without using click action. Does everyone know the other way? Thank you very much.

I have a ListActivity where the list items are defined in another XML layout. The list item layout contains an ImageView, a CheckBox, a TextView and such.
What I want is to set an onClick listener to the CheckBox in each list item. That is easy enough. The trouble is I need that onClick handler to know which position in the list it is.
I'm attaching the listener to the CheckBox in getView after that convertView has been inflated. The getView method has a position parameter, but I cannot reference it in the onClick handler for my CheckBox. I understand why, but I don't know how to get around it. How do I accomplish this?

I need to make a service that capture all touch events, not in a specific view or when an specific activity is open. This service is started when the boot is completed (and I have an app to stop/play this service when I want it). So it write something (in a Toast) when the user touch any place in the screen.
Can I do this? Or only in specifics things (with OnTouchListener and adding specifics views, for example)?

Instead of finding the button (as per the id specified in xml) i.e
CODE:.....
Is it possible to set the Listener class name directly in the xml definition. Most of the time dealing with id's for attaching listeners is affecting our productivity.

As known, when using the setContentView() method, a view can be displayed on screen.
My question is whether there is a way to receive an event when the view is actually displayed on screen (since it takes some time for the view actually being displayed after the setContentView() method has been called).

I have a web-view with Html content.I want to calculate height of web-view when it is scrolled.
The method *getScrollY()* can return the Y scroll but the problem is that when I scroll web-view 2-3 time continuously it takes some time in scrolling.
I just want to know if there is a way to get event like *ScrollFinish()* so that I can get actual size of web-view when scroll finish.

I use Google Calendar to organize my life, and rely on the email reminders to keep me from forgetting events and to know when to act on them. With 2.1 I had no issues, Google Calendar was synced to the stock HTC calendar app on EVO. I had the calendar set to view in "agenda" mode. Now since updating to Froyo, when I open the calendar app in agenda mode, the events have bell icons to the right of them, this is new. If I tap the event to open it and view the details of the event, when I return to the main agenda viewing mode of the calendar the bell is gone.
The phone then syncs with Google Calendar, and deletes all of the scheduled Email Reminders that I have set up for the event. This was not a problem with 2.1. No bells showed to the right of the events in agenda mode, and I could tap into the event to view the details without deleting email reminders on Google Calendar. With Froyo, by simply tapping the event to view the details it is effectively wiping out all reminders, rendering the calendar useless. This making me wish I had never updated to Froyo. The calendar and reminders are the single most important function on my phone, and with Froyo it seems to be incredibly flawed.

I've been trying to write a little application that recognizes custom events in Android: you hold your finger over a TextView for a certain length of time, and it changes color.I'm using the MotionEvent coordinates and checking if they are within the bounds of a particular TextView, which is within a table.I am just attaching the onTouch listener to the table within the activity.But I get weird errors: the coordinates seem to be off by one view (i.e. if I touch the view below the view above reacts); or sometimes one will react, and the other will not. Any idea what might be going on?
