prc.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <string-array name="productlar"> <item>product1</item> <item>product2</item> <item>product3</item> <item>product4</item> </string-array> <string-array name="prices"> <item>43.99</item> <item>42.66</item> <item>41.61</item> <item>40.47</item> </string-array> </resources>
i'm trying find code few nights did not result. can transfer prices prc.xml
listview
following code. code conveys same products listview
.
listview fiyatlistele=(listview)findviewbyid(r.id.listview); string[] arrayim=getresources().getstringarray(r.array.prc); arrayadapter<string> adapter=new arrayadapter<string> (this,android.r.layout.simple_list_item_1,arrayim); fiyatlistele.setadapter(adapter);
i have calculate product final price before transfer listview. example: products prices(in xml) must multiplied 2 transfer listview. (it change final price according customer)
why don't this, simple multiplication 2 array elements. of course array in string format have parse values double
before multiplying 2.
listview fiyatlistele=(listview)findviewbyid(r.id.listview); string[] arrayim=getresources().getstringarray(r.array.prices); for(int = 0; < arrayim.length; i++) { arrayim[i] = ((double.parsedouble(arrayim[i]) * 2) + ""; } arrayadapter<string> adapter=new arrayadapter<string> (this,android.r.layout.simple_list_item_1,arrayim); fiyatlistele.setadapter(adapter);
