Android :: Passing Touch Events From One Gallery Widget To Another Widget
Feb 18, 2010
I am trying to pass the same touch events on one widget to the other so they both scroll at the same time and in same way. I have two Gallery widgets one above and one below. If the above one is scrolled then I want to pass the same touch event to the bottom widget so it also scrolls the same way.I have tried to use dispatchtouchevent events but I am facing an issue where in if the bottom gallery widget has some edit text then the edit text gets the key event and both widgets doesnt scroll anymore.I have tried to set focussable and editable to false on edittext even then it gets the touch events.I think I am going in the right direction. However I need some assistance in doing the right way.

I am trying to create app widget.In this widget I have added one image button.If i click on this button i should pass list of object to next activity.Before passing this list to activity I am converting it to parceable list and adding it to bunddle and puting that bundle to intent.This logic is working fine in android 1.6, but this is not working in Android 2.1.In android 2.1.I am getting Null pointer excepion when I try to access this list in next activity.To solve this problem I tried to pass only String data through bundle,in next activity String is displaying properly,but when I try to pass list,then only i am not getting list in next activity.

There is a task to make smt like todo list on widget (with dinamic number of elements), how to organize this list for click support on this elements. I only found how add click event on one widget layout element (with setOnClickPendingIntent), and how send text to widget element TextView. But it's unclear how handle click events for sub-elemets, or how get click coordinates(or item) where was click event. I saw widget "Agenda widget" - and it work fine with clicking on different calendar rows.

Does anybody else have this problem? My Calendar widget that comes with Android (Calendar) has been synched with my google calendar, but it only shows events for tomorrow, and even sends notifications for those events a full day early.
Example:
Today is Feb 11th. I have an event today (we'll call it A) and an event tomorrow (we'll call it B)
The calendar widget has a blue bar across the top that says "Thu 11" This is correct! Below that it has a white field that says
"Feb 12
Event B"
If I click on the widget it takes me to today's page in the calendar application, the 11th which shows me today's event.
How can I get my calendar widget on the front page to show me what is happening TODAY and give me notifications for it TODAY?

I'm trying to realize how the focus and selection in the Gallery widget is doing their job. I'm facing weird situations when trying to update information (TextViews and Spinner) upon a selected item in the Gallery. The focus and selection is lost. So, using the resource gallery_item_background will end in showing the "unselected" background for the current selected image. I have used the .xml that came with the android sdk, and I can't realize how this is happening. I have set setFocusable(false) and setFocusableInTouchMode(false) to all other Views to try out (and true for the Gallery) without any luck.
I have also add 'in-situ' debug, that is, a menu that updates differents widgets when onItemSelected() is called. So I can see while using the application how the background resource is applied. When set to 'no update' the obvious thing happens. None of the widgets are updated with new values, and the background resource works as expected. When set to 'manual update' (an update in the listener that do: .setText() on the textview) does work depending the current View that is showing the TextViews (I have a ViewFlipper that display 2 differents Layout of the TextViews)...............

Is it possible to scroll a Gallery widget pragmatically? I see Gallery inherits scrollTo() and scrollBy(), but that scrolls the entire widget itself, not its content.
Is there some obvious way to do this that I'm missing, my searches are coming up empty? I don't want to have to do a copy/paste/hack from git hub if possible.

I'm working on a little Player with Playlist and use the Gallery Widget to visualize the Playlist. I tried to scroll the Gallery Widget manual to an active item, but the Widget don't support any functions to do this. There are several methods in the Gallery.java class
movePrevious() moveNext() scrollToChild( int pos ) but the visibility of this methods is default or private. So i can't override this functions, if I Inherit from Gallery class.
can any one please help for a solution to scroll the Gallery manual?

The native calendar widget doesn't display the current days events only the upcoming ones. Is there a way to change this or a different calendar app that is better?

At one time I thought I could edit (aka change) a previous event by:
1) Selecting the date on the calendar view
2) Selecting the event
3) This brings me to the "Event details". When the the screen opens I see the whole edit menu for a moment. Then I only see the event with date and time and a line that says "my calendar" with an icon. The menu's only choices are "add reminder", "delete" and "share vCalendar".
At one time I had an way of editing the event. I just cannot figure out how to do it now.

From the People widget or "contacts" there is a tab that has Facebook "updates and events". While this is nice I would like to clear out the updates once I have seen them and can't for the life of me figure out how to do that. I don't use the auto update feature so when I press refresh I get everything which is fine but once I have seen them I would like to delete them off my Hero.

Gallery in Android is only horizontal scrolling support. And we want make one with vertical scrolling support.
We got plans below. Can anyone give us some advice about which one is right?
1) Linearlayout ( We think it's bad)
2) ListView ( We think it's a good option and get a little worry about performance--too many pictures!)
3) subclass of AbsSpinner like Gallery and do something like Gallery source.
Which one is easy, time-saving and less performance or other problems.

I'd like to programmatically move between images in the Gallery widget, with animation.
I can change the currently displaying image using the setSelection(int position) method, however that does not animate. Then there's setSelection(int position, bool animate) but the extra boolean on the end there doesn't appear to do anything.
In the source of Gallery it appears that it can handle DPAD key-presses, so a work-around I thought of was to fake the key-presses. Eg.
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT))
However I can't get this working for some reason. Anyone tried this?
I notice three of the widget's methods I'd love to use moveNext(), movePrevious() and scrollToChild() are all private and unusable.
Does anyone know how I might be able to do this?

I am developing an application in Eclipse build ID 20090920-1017 using android SDK 2.2 and testing on a Google Nexus One. For the purposes of the tests below I am using the IME "Android keyboard" on a non-rooted phone.I have an EditText widget which exhibits some very strange behavior. I can type text, and then press the "del" key to delete that text; but after I enter a 'space' character, the "del" key will no longer remove characters before that space character.An example speaks a thousand words, so consider the following two incredibly simple applications.Example 1: An EditText in a LinearLayout widget:
package com.example.linear.edit;
import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.EditText;
import android.widget.Gallery;
import android.widget.LinearLayout;
public class LinearEdit extends Activity
@Override
public void onCreate(Bundle savedInstanceState)
{super.onCreate(savedInstanceState);
LinearLayout layout = new LinearLayout(getApplicationContext());
layout.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT, Gallery.LayoutParams.MATCH_PARENT));
EditText edit = new EditText(getApplicationContext());
layout.addView(edit, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
setContentView(layout);
}Run the above application, enter text "edit example", then press the "del" key several times until the entire sentence is deleted. Everything Works fine.Now consider example 2: An EditText in a Gallery widget:
package com.example.gallery.edit;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.Gallery;
import android.widget.LinearLayout;
public class GalleryEdit extends Activity
{ private final String[] galleryData = {"string1", "string2", "string3"};
@Override
public void onCreate(Bundle savedInstanceState)
{super.onCreate(savedInstanceState);
Gallery gallery = new Gallery(getApplicationContext());
gallery.setAdapter(new ArrayAdapter(getApplicationContext(), android.R.layout.simple_list_item_1, galleryData)
@Override
public View getView(int position, View convertView, ViewGroup parent)
{LinearLayout layout = new LinearLayout(getApplicationContext());
layout.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT, Gallery.LayoutParams.MATCH_PARENT));
EditText edit = new EditText(getApplicationContext());
layout.addView(edit, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); return layout; setContentView(gallery);
}Run the above application, enter text "edit example", then press the "del" key several times. If you are getting the same problem as me then you will find that you can't deleted past the 'space' character. All is not well.If anyone could shed some light on this issue I would be most appreciative.

This seems like an obvious requirement for a calendar widget, but I can't get it actually show me today's events. For a few days leading up to an event, it'll inform me when it's coming, but when it's here, nada.
So is there any way to actually make the widget show the current day's events?

I didn't found any way how to detect coordinates of the touch on RemoteViews.Is anybody aware of some trick how to detect it. Only idea I have is create layout with grid of transparent buttons, put by widget's bitmap as background of such a layout and to every button set PendingIntent.

In the Android API examples there is a Snake game. This game uses a class called SnakeView, which inherits from TileView.
I am doing something very similar to this. I am inheriting from TileView to create a class (SkyView), which will become a square board for a board game (similar to the board for Checkers).
However, I would like for my game board to be 400x400 pixels in size, which will be bigger than the screens of some Android devices (such as the G1). And I would like for the user to be able to freely scroll and drag the board around with their finger (both horizontal and vertical scrolling/dragging).
Can someone please point me in the correct direction for implementing this? The board must be no smaller than 400x400px in size. And however much of the board that can be displayed at once on the screen, should be displayed at once.
Should I wrap my SkyView widget in an AbsoluteLayout and use Scrollbars? If so, what Scrollbar properties to I need to use? I played around with Scrollbars in both directions but couldn't get it to work. Is there another view layout I should put it inside? Code examples would be nice! Thanks for the help. I am at a loss with this one.
