[android-developers] how to depress the onLongClick() when drag a view
Hi, I have a View and I can drag it. It also has a onLongClick() method so it can respond to the long press on the screen. The problem is when I drag it , the onLongClick will also be triggered . Anyone have an idea to depress the long click detection when i move it . Thanks in advances.

Re: [android-developers] Re: how to depress the onLongClick() when drag a view
thx for your reply but it doesn't work as will. setLongClickable() in case MotionEvent.ACTION_MOVE phrase doesn't work. But I have figure out the way. The view default implementation will cancel the long press check on ACTION_MOVE,so I just call the super.onTouchEvent to let the default implementation takes effect. 2010/4/19 grace grace.a...@wipro.com hi, try disabling the longClick event using public void setLongClickable (boolean longClickable) function while ur performing the drag operation and enable it after that.. so that u can have both the functionalities..

[android-developers] how to get the bitmap data before it is drawn on the screen
Hi there, To any normal android Widgets based on View( Button ,TextView ...), I wanna manipulate the bitmap data before it is drawn on screen.

If there is any way that I can get the bitmap data before it's drawn to screen, so I can prevent it from being displayed , but grab the data, put it on the intent for some further use?

[android-developers] relation between ViewRoot and View
Hi , Can any one give more information about ViewRoot and what's the relation between viewroot and view? I found a Viewroot create a surface at its' constructor, which I think is the real bitmap data goes to. So I guess every view has it own viewroot, every view has a surface for drawing and the surfaceflinger will finally blend all surfaces together, but I found it's definitely wrong. How view and viewroot cooperate is quite ambiguous to me. Any information will be appreciated! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: How to send motion Event down to another activity
Hi About the make your window not fullscreen. The activity starts full screen. I remember some theme can make the activity not fullscreen. But it's not so flexible, the floating window will be centered on the screen and can not be moved(correct me if I'm wrong) Besides the theme, are there any other way to make a activity not fullscreen ? 2010/2/9 Dianne Hackborn hack...@android.com Hi, You can't get the activity behind unless it is your own. Otherwise it is in another process and untouchable by you. There is only ever one activity resumed at a time, so if you are in the front and resumed, then the home screen (or whatever) behind you is paused (though not stopped because it is still visible). The only way to let events get to the window behind yours is to make your window not fullscreen, and set WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL to tell the window manager that touches outside of your window should be delivered to whatever is behind it.

[android-developers] How to send motion Event down to another activity
Hi, My Activity using transparent Theme in AndroidManifest.xml *android:theme=@android:style/Theme.Translucent* * * Which works fine. When it's started from the Home screen, we can see both the content of my activity and the home screen below it. It gives the feeling of floating . Furthermore, to make it real floating, the motionEvent has to go down to the home screen to let the home screen response some motion touch. But I have no idea of 2 things : 1. Whether the event can be send down to any thing behind the current activity. 2. If so, how. The solution don't need to be restricted in API level. I mean if any solution need us to rewrite home screen or something else, It's also ok for me. Thanks for any suggestion.

[android-developers] how to add a new method in framework
Hi all,
For some reason I need to add a new public method in Canvas.java just as
bellow:
/**
*
*/
public Bitmap getBitmap() {
if (mBitmap != null) {
return mBitmap;
} else {
return null;
}
}
After that I make update-api, then make successfully.
the problem is when I develop in eclipse, the eclipse won't recognize the
new getBitmap method and won't get apk build.
Is there anything else I should do to let eclipse work with the new method?
Thx in advanc.

Re: [android-developers] how to add a new method in framework
Hi Romain,
thanks for ur replay. I totally agree with you that the @hide will be the
better way. But I don't think the @hide really solve my question. I guess I
don't make it quite clear.
The scenario is :
1. I have my eclipse and sdk installed on my PC (windows xp)
2. The android source tree stays in vmware (Ubuntu), the make also happens
here.
The question block me is:
After I add some new method in framework, the process of make is fine. After
that , I copy all 3 img file in mydroid/out/target/product/generic from
Ubuntu to my windows SDK directory , overwrite the exists files. When I
coding in eclipse, the IDE seems have no idea of the new method that I have
add. The new added method will be treated as syntax error. So no apk will be
created.
I guess there are something more that I should do to let my eclipse
recognize my new method. Give me a hand~
2010/1/25 Romain Guy romain...@android.com
Do not add new public APIs this way. This is fine if you want to
contribute changes to the Android Open Source Project (and if they are
accepted of course) but if it's for your own version of the platform,
you should just make the method public and use the @hide javadoc tag
so that you don't need make update-api.
