Hello soniya,

you could use this:

this will work if you alter the getItemId(..)-method in the ImageAdapter we created (make it return the ResourceID):


then use the code in the :src: [TinyTut] - Get ResourceName by its ID-Tutorial to determine the name 'behind' the resID.

Hi ,
how can we take image from sdcard and put that into in a array?

Hello +- , could u explain the usage and funtionality of the function getScale in ImageAdapter, i am a little confused about it...thx a lot!!

plusminus,

It seems like in the latest SDK that the images don't actually scale. I've tried using this exact tutorial but no matter what, all of the images are 150x150.

Do you know why this is or how this can be fixed?

Thanks so much!

for some reason Eclipse cannot add for me a correct import when I'am using 'Source/Organize Imports' option, so need to add

in this example method getScale() is never used. what for is it. or where I need to add a call ?

It gets called by the System and returns howbig the images should be scale depending on the [font=Courier New]offset[/font] to the middle on. (The formula calculates smaller values, the bigger [font=Courier New]offset[/font] is)

It will be better if you show us your source code.
Maybe, you put the line: ((Gallery) findViewById(R.id.gallery)).setAdapter(new ImageAdapter(this));
before call: setContentView(R.layout.main);
if so, you should call setContentView(...) first, then you can call findViewById(...)

If it's not help, please show us your source code
