Android :: Mismatch Of Event Coordinates And View Coordinates

Jun 30, 2010

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?

Android :: OnClick Event Not Firing?

Sep 20, 2010

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.

Android :: How To Let Parent Handle Onclick Event For ListView?

Jul 27, 2010

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?

Android :: OnClick() Event On An Item Of ListView Custom Row Layout

Nov 15, 2010

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.

Android :: Haptic Feedback: OnClick() Event Vs HapticFeedbackEnabled In The View

May 13, 2010

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?

Android :: OnClick To Run Application On 1.5?

Nov 26, 2009

just a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]

Android :: Set OnClick For Whole Screen?

Aug 24, 2010

I know how to set a listener for.. let's say a button or a editext so that when clicked some action happens:

buttonOReditextl.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Action goes here } });

how can I set a onClick event for when the user taps/ clicks on the screen? or the surface.. I'm not sure? I want a picture to be taken when the camera is on.. but don't know how to make a listener to all the camera view instead of having a button to take a picture.

Android :: Open New View By Onclick

Jun 28, 2010

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);}

Android :: Implement OnClick For DialogPreference?

Sep 1, 2009

I have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed. I think I need to implement onClick for this dialog but I am not sure where to do this. I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.

public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {

private static final String LOG = "test"; private DialogPreference mfactory;

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ....................

Android :: Imageview OnClick Animation

Feb 16, 2010

I guess this is kind of an odd question but i have tried setting onClicklistener on an ImageView and it has worked. But the problem is that the user cannot sense the click. I mean if some of u have worked on other mobile environs(like apple iphone) then wen we click on a Image in other environs then it gives an effect on the image so that the user can understand that the image has been clicked.

I have tried setting alpha using "setalpha" method but it doesnt work. Though the same thing is working fine on onFocusListener implementation. Can some1 suggest a different way to modify the image on click...
