Android :: Detect Triple Tap On View?

Jul 20, 2010

I haven't spend much time on Gesture Detector or anything of that sort.

My requirement is very simple, Given a View (any view), how do I detect triple tap on that?

Of course a timer and a counter can help me, but I am looking for something more sophisticated that that.

Android :: Detect When User Taps On View?

Jan 10, 2010

I want to detect when a user taps anywhere in a view in my Android application. My code looks like this:

linearLayout = (LinearLayout) findViewById(; // main layout
// ...
// ...
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(this, "Touch!", 1000);
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Toast.makeText(this, "Down!", 1000);
return true;
return false;

but when I click on the view, I don't get Toast! Do touch events work in the emulator -- or have I got something wrong in my code?

Android :: Get Touch Event In Any View (droid)?

Oct 19, 2010

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)?

Android :: Detect If A View's Parent Activity Is Paused

Jun 20, 2010

In one of my Activities I have a ListView that displays a list of locations. For each list item I want a little arrow icon that points in the direction of the corresponding location. I implemented this icon by extending ImageView. This custom View has a listener that reacts to changes of the device's orientation by rotating the icon image accordingly. I register the listener in the onAttachedToWindow() method and unregister it in onDetachedFromWindow(). This kind of works but the problem is that onDetachedFromWindow() sometimes gets called only a long time after the containing Activity has paused. Also, the whole layout overall seems a little hacky. So my question is: Is there a proper way to unregister the listeners or would you implement this in a completely different way to begin with?

Android : Receive Event When View Is Actually Displayed On Screen?

Jan 19, 2010

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).

Android : Missing Action_Up / Detect Lifting Finger From View

Nov 4, 2010

I've got a view where I override onTouchEvent to detect touching the view with a finger and also to detect lifting the finger from the view. I'm getting the ACTION_DOWN event but not the ACTION_UP event. In fact, onTouchEvent isn't getting called when I life my finger. Could it be that the finger-down and then finger-up is considered a click event and so onTouchEvent is not called? If so, what use is ACTION_UP?

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:

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?

HTC EVO 4G :: Froyo / Tapping Event To View Details Wiping Out All Reminders

Aug 3, 2010

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.

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 :: Populate View Flipper Child View With List View?

Aug 2, 2010

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:

The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
else if (v == btnSpecialEffects){
