android - Images in SimpleCursorAdapter -

i'm trying utilize simplecursoradapter viewbinder image database , set listview item view. here code:

private void setupviews() { mnewsview = (listview) findviewbyid(r.id.news_list); cursor cursor = getnews(); simplecursoradapter curadapter = new simplecursoradapter( getapplicationcontext(), r.layout.cursor_item, cursor, new string[] { "title", "content", "image" }, new int[] { r.id.cursor_title, r.id.cursor_content, r.id.news_image }); viewbinder viewbinder = new viewbinder() { public boolean setviewvalue(view view, cursor cursor, int columnindex) { imageview image = (imageview) view; byte[] bytearr = cursor.getblob(columnindex); image.setimagebitmap(bitmapfactory.decodebytearray(bytearr, 0, bytearr.length)); homecoming true; } }; imageview image = (imageview) findviewbyid(r.id.news_image); viewbinder.setviewvalue(image, cursor, cursor.getcolumnindex("image")); curadapter.setviewbinder(viewbinder); mnewsview.setadapter(curadapter); }

i getting :

android.database.cursorindexoutofboundsexception: index -1 requested, size of 60

while executing byte[] bytearr = cursor.getblob(columnindex);. have thought doing wrong?

i think cursor.movetofirst() has not been called cursor throwing android.database.cursorindexoutofboundsexception.

before using cursor should check cursor empty or not calling cursor.movetofirst(). position cursor @ first position.

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? -

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison
