Here is the code.

static int eur = 0;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail_view);
calculatePrices(); //I WANT TO CALL THIS> DONT KNOW HOW.
}
public ArrayList<Expense> getExpenses(View v){
int finalPosition = getIntent().getIntExtra("claim_position",0);
Toast.makeText(this, finalPosition+"",Toast.LENGTH_SHORT).show();
ClaimListController ct = new ClaimListController();
Collection<Claim> cl = ClaimListController.getClaimList().getClaim();
ArrayList<Claim> clist = new ArrayList<Claim>(cl);
Claim claim = clist.get(finalPosition);
ArrayList<Expense> elist = claim.getExpenses();
return elist;
}
public void calculatePrices(View v){
ArrayList<Expense> list = getExpenses(v);
for (int i = 0; i < list.size(); i++){
Expense e = list.get(i);
if (e.getCurrency().equals("USD") ){
GetDetails.usd += e.getPrice();
}
if (e.getCurrency().equals("CAD")){
GetDetails.cad += e.getPrice();
}
if (e.getCurrency().equals("AUD")){
GetDetails.aud += e.getPrice();
}
if (e.getCurrency().equals("EUR")){
GetDetails.eur += e.getPrice();
}
if (e.getCurrency().equals("GBP")){
GetDetails.gbp += e.getPrice();
}
}
TextView usds = (TextView) findViewById(R.id.tot_usd);
usds.setText(this.usd);
TextView cads = (TextView) findViewById(R.id.tot_cad);
cads.setText(this.cad);
TextView auds = (TextView) findViewById(R.id.tot_aud);
auds.setText(this.aud);
TextView eurs = (TextView) findViewById(R.id.tot_eur);
eurs.setText(this.eur);
TextView gbps = (TextView) findViewById(R.id.tot_gbp);
gbps.setText(this.gbp);
}
}
I commented the line I am trying to call the method from. I know I need to pass it a VIEW argument, but I do not know how. I tried View v, this.view, and unless i did it wrong, i do not know what I am doing wrong. If anyone could help me it would be awesome. I will also post the logcat.

You managed to call it since the crash was inside that method.
Clean up your project, check if there are no errors in any XML files so the R class can be successfully generated and then run the project. The problem is in the TextView resources.
Edit: you are trying to set a int to a TextView, and you just can't. Use String.valueOf in each of the lines you are setting the values.
usds.setText(String.valueOf(this.usd));
OR
usds.setText("" + this.usd);
