[android-developers] Re: Slide Views ( like Google Scoreboard app )
I tried creating something similar like a home screen a while back and ended up using the View Flipper. As you pointed out, you cannot view the next view while dragging the screen. and thts why, i started writing my own layout. I wasn't able to finish it but it can be done by writing your own layout. For example, If the width of the screen is 320, u can have three or however many linear layouts of 320px each in a horizontal linear layout. Then, all you need to do is implement the onToucListener and the OnGestureListener . overwrite the ondown, onfling, onup , ontouch methods to handle when the user starts to scroll left/right. do some math to find out which view is the user on, and then perform the necessary view transitions.

[android-developers] Content Providers and Network Requests
Hello, As per the subject, i am making an app that is dependent on data that comes from a network request. I was using the UserTask class (Made by Mr. Romain Guy) to make the network calls and get my data and everything worked. But now, i want the data from this app to be available to other apps as well and thus, the only way that data could be shared between applications is by using a content provider (thats what i have read so far). My question was: Is it possible to use a thread or the UserTask class inside a Content Provider and if yes, then since the request to the server can take a long time, how do we change the query method of the content provider to handle such a delay as it is suppose to return a Cursor object. In my initial approach, i was using a listener that took care of updating the Application when the data was available but i am not aware of a way to use a listener with a Content Provider. Any help or ideas would be helpful. Thanks - Kavik --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

ListView is a kind of View, so you should be able to attach the GestureDetector to your ListView as well. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Layout like android's Home Screen
Hello, I am currently using a View Flipper to create views on the fly and allow the user to move between views by performing a fling action on the screen. But the way it currently works is that after the fling action is performed, the changing of the view is triggered which uses a move in and move out animation. What i want to have is something like the home screen of android where the user can see the new view while he is trying to drag/scroll the screen. I want a view that the user can just drag to either go to the right or the left side and the views on either side can be a part of the current view or can be new views that are inflated at runtime. Does anybody know how to implement this? Thoughts? Thanks - Kavik --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Mouse Gesture for Navigation?
You can use the android.view.GestureDetector to detect gestures on a
view.
First, you can implement the GestureListener interface.
Second, you can create an instance of gesturedetector for your
activity, and in your activity's onTouch method, call the gesture
detector's instance's onTouchEvent method.
and That's it.
Then, you can detect all sorts of events like fling, scroll, touchDown
etc.
public class YourActivity implements OnTouchListener,
OnGestureListener
{
onCreate()
{
GestureDetector gd = new GestureDetector(this);
// Set the ontouchListener for your View.
}
public boolean onTouch(View v, MotionEvent event)
{
return gd.onTouchEvent(event);
}
// You can write your code to do whatever whenever your view sees
anyone of the below events triggered on your view.
@Override
public boolean onDown(MotionEvent e)
{
// TODO Auto-generated method stub
return true;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float
velocityX,
float velocityY)
{
}
@Override
public void onLongPress(MotionEvent e)
{
// TODO Auto-generated method stub
}
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float
distanceX,
float distanceY)
{
// TODO Auto-generated method stub
// previous.setText(Scroll);
return false;
}
@Override
public void onShowPress(MotionEvent e)
{
// TODO Auto-generated method stub
}
@Override
public boolean onSingleTapUp(MotionEvent e)
{
// TODO Auto-generated method stub
return false;
}
I hope it helps.

I was wondering if this is easily implementable with the current
SDK... basically I'd like to use a hold and drag left or right for
navigation.
So if the user wanted to change say a page they would hold their
finger down and then push left or right.
I know there's a Firefox extension that calls this mouse gestures, but
didn't know if anything was built in that could handle this.

[android-developers] Re: Layout like android's Home Screen
Wow.. I totally was not aware of VelocityTracker and Scroller. It looks very useful, and I guess this could have saved me a lot of headache.. Is there any (API) demo for how to use them? You might want to have a look at the android.view.GestureDetector for your Views. You can detect all sorts of gestures on your views using this. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Use dynamic string instead of Integer in findViewById
Currently, findViewById uses a R.id.viewid which is an Integer to find views. Is it possible to give findViewById a string like R.id.field_1_text? The reason i want to know this is then, i can use a loop and change the values for fields like R.id.field_1_text, R.id.field_2_text, R.id.field_3_text rather than setting all of them sequentially. Is it possible to convert a string to a resource id before passing it in to the findViewById method. I tried looking on the groups but didn't find anything that could help me in this case.

[android-developers] Re: Image Button?
Is there a way to have the selector code for multiple ImageButtons in one xml file. So, if i have 10 buttons, i want to have all the code in one file and not in 10 xml files to set the background for each button. Is there a way to give each selector tag an ID? and then use different selectors for different buttons but have them all together in one location?

[android-developers] Re: Problem with TableLayout
How about telling the TableRows to evenly take the height from the Table layout. Is that possible? So, for example in my main.xml, the TableLayout is taking up the whole screen. And all the table rows height is equal to what they need for their content. Thus, their is some extra space left at the bottom of the screen. I want the rows to spread out so that the whole page is taken. Can that be done using a TableLayout? About using a Linearlayout, i have used that but i need to test it with a TableLayout now. Also, would you have an idea in terns of the rendering time for both LinearLayout and TableLayout. Which one is faster and takes up less memory? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Problem with TableLayout
I have two questions regarding the use of a TableLayout. 1) First of all, i am using a horizontal orientation. The content of my TableLayout gets hidden at the bottom of the screen if the title feature is not turned off. if i use requestWindowFeature(Window.FEATURE_NO_TITLE); then. all the contents fit well. To me, it looks like it calculates the height needed for the TableLayout and then just adds the title above it which pushes the entire layout down and hence, some stuff gets hidden. Is this an issue and if yes, was it there in the old SDK? What would be a workaround? 2) My second question is regarding a TableRow. By default, the layout_height for a table row and its children is set to WRAP_CONTENT. If i need the row's layout_height property to be set to FILL_PARENT, how can i do that? Is it possible? or is there a possible workaround? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
