Declare the ed_text and mViewPager in your onCreate like this final EditText ed_text =(EditText)findViewById(R.id.editText1); final ExtendedViewPager mViewPager = (ExtendedViewPager) findViewById(R.id.view_pager); and now you can access the ed_text value in the bt_Goto click listener like this bt_Goto.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(ed_text.getText().toString().length() > 0){ mViewPager.setCurrentItem(Integer.parseInt( ed_text.getText().toString())); } } }); 1 solved Get … Read more
Its quite easy to implement a replacement for atoi(): int strToInt(const char *text) { int n = 0, sign = 1; switch (*text) { case ‘-‘: sign = -1; case ‘+’: ++text; } for (; isdigit(*text); ++text) n *= 10, n += *text – ‘0’; return n * sign; } (Demonstration on ideone) It doesn’t … Read more
