[android-developers] Re: relation between ViewRoot and View
Some comments in ViewRoot.java ViewRoot: The top of a view hierarchy, implementing the needed protocol between View and the WindowManager. BRs Guobin On Feb 20, 4:53 pm, sheng wang banxia...@gmail.com wrote: 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.

[android-developers] Re: Capturing HOME intent with receiver programmatically
Home Key events are processed by PhoneWindowManager, that's to say
consumed by Android system.
That's why your activity can not see it.

I am trying to capture my activity to handle HOME button press with a

however, successfully register and capture this intent filter if I
declare it in a manifest.xml activity section. Here's the code for
the receiver:
///
BroadcastReceiver br;
br = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
return; // I put a breakpoint here to see if this gets called
}
};
IntentFilter intf = new IntentFilter();
intf.addAction(Intent.ACTION_MAIN);
intf.addCategory(Intent.CATEGORY_HOME);
intf.addCategory(Intent.CATEGORY_DEFAULT);
registerReceiver(br, intf);
///
Does anyone know why this doesn't capture the home button click?
By the way, I tried working around this by creating another activity
and specifying its intent filter in the manifest. I set the activity
enabled=false in the manifest but I couldn't figure out how to
enable that activity at run time. Bottom line, I only want to
register the home button intent filter for my application only when my
application is running, and I can't figure out how to do that.
