how to retrieve the bundle from onCreate(bundle) method?

sommeralex · by **sommeralex** » Wed Feb 27, 2008 12:20 am

Hello..

Maybe someone can bring light into my dark.. first, i thought if I start an Intent by

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
Intent i = new Intent(thisContext, myClasstoStart.class);
 
i.putExtra("test.hello", "hello!");
 
startSubActivity(i, 123);
 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

that myClasstoStart will have the Bundle Data in his onCreate method

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
onCreate(Bundle bundle){
 
}
Parsed in 0.029 seconds,  using GeSHi 1.0.8.4

so, that i could get the data by

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
bundle.getString("test.hello");
 
Parsed in 0.033 seconds,  using GeSHi 1.0.8.4

but this didnt work. i had to make this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
Bundle bundle2 = getIntent().getExtras();
 
bundle2.getString("test.hello");
 
Parsed in 0.035 seconds,  using GeSHi 1.0.8.4

why? who puts data to the onCreate Bundle if not my Intent?!

thx for any help..

Hi sommeralex,

the Bundle parameter icicle is used to save data when the activity is being re-initialized after previous being shut down, and then this Bundle contains the data it most recently supplied in onFreeze().

thx - i know this diagramm already - but this doesnt chance anything on the confusing use of onCreate.

i thought, if i CREATE it, onCreate will be called. THEREFORE, if i pack it through an Intent and give data to it, (putExtra-method) i could retrieve the information directly from the parameter which is passed through by onCreate(bundle)...

so far...

Hello sommeralex,

data packed to the Intent that starts an Activity can be grabbed with:

this.getIntent().getExtras...

i know

but this is what i was wondering for. my natural approach was that i can grab it through the onCreate(bundle) parameter the same as in java by main(String[] args)
