Hello guys,
I have a question on the same theme.
I need to use R.drawable.id's dinamicaly, depending on the country choosen,
more precisely,depending on a "country" variable.
For example, my screen contains a country flag. If the Deutschaland is the
choosen country, i have to display something like this:
ImageView flag;
flag=(ImageView)findViewById(R.id.ImageView01);
flag.setBackgroundResource(R.drawable.flag_de);
Inside android application, in "res/drawable-hdpi" i have saved all needed
flags with the following names: flag_de.jpg, flag_uk.jpg, flag_ro.jpg and so
on.
How can i set background image for this "flag" value dynamically?????
If i use the following way, there are too mush code:
if (country.equals("DE") {
flag.setBackgroundResource(R.drawable.flag_de);
} else if (country.equals("UK")) {
flag.setBackgroundResource(R.drawable.flag_uk);
} else if (country.equals("RO")) {
flag.setBackgroundResource(R.drawable.flag_ro);
}
I want to create somehow "R.drawable.flag" by appending the country extension
"de" .
String countryFlag="flag_"+mySource.countryExtension ; //something like
flag_DE
countryFlag=countryFlag.toLowerCase(); // =flag_de
flag.setBackgroundResource(R.drawable.countryFlag); // of course, it's
not working
Could anyone give me a suggestion please ?
Thank you
Lidy

I'm just getting into developing my app, which will have quite a
number of activities and thus quite a few XML files to lay out the
screens and define all the views. What I'm just seeing is that if I
assign the IDs using "@+id/name", I'll have to have a unique name for
every widget on every screen since all the symbols get defined in one
big R.java file.
Or can I just generate the definitions once in one of the XML files
and then reference them in the other layout files? For example, if I
have a TextView that I'd like to call "surname" in multiple layout
files, can I declare it one of the files using "@+id/surname" and then
simply use "@id/surname" in the other files? I assume that as long as
all the IDs are unique within a layout file, all is OK.
