java - Why is only 'else' part getting executed, even if 'if' is true? -

-

here main activity:

package com.santosh.sampleapp;  import android.app.activity; import android.content.intent; import android.os.bundle; import android.widget.button; import android.widget.edittext; import android.widget.textview; import android.widget.toast; import android.view.gravity; import android.view.view; import android.view.view.onclicklistener;  public class main extends activity {     edittext password_field;     textview tv_err;     button login;     /** called when activity first created. */     @override         public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          password_field = (edittext) findviewbyid(r.id.password_field);         tv_err = (textview)findviewbyid(r.id.tv_err);         login = (button)findviewbyid(r.id.login);         final string password = password_field.gettext().tostring();           login.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 try {                     if (password.equals("password")) {                         tv_err.settext("good pass");                     } else {                         tv_err.settext("wrong pass");                     }                 } catch (exception e) {                     tv_err.settext(e.tostring());                 }              }         });     } }

even if type password @ textview, shows me wrong pass message.

here src/layout/main.xml if helps:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     > <edittext android:id="@+id/password_field"     android:hint="@string/password_hint"     android:inputtype="textpassword"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     /> <button android:id="@+id/login"     android:text="@string/get_message"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     /> <textview android:id="@+id/tw_err"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     /> </linearlayout>

because password not updated. contains original value. update so:

if (password_field.gettext().tostring().equals("password")) {

btw: keep on using final keyword as possible! minimize mutable state in app , you'll happy man.

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
