Getting weird text back with EditText.toString() method in Android project. Why?

You are calling toString() on a View Object, which probably does not have a toString() defined.

I believe you want to call this:

editText.getText().toString()

Passing glance at the API suggests you should use the getText() method. toString() is a general method that applies to Object and all its subclasses (i.e., everything that isn't a primitive, to my knowledge). It's often overridden to supply more useful strings, but by default, it reports something just like what you posted - a sparse description and the object's hashcode. To be clear, the API defines toString() as:

getClass().getName() + '@' + Integer.toHexString(hashCode())

You can't use the 'toString'-method on this, use 'getText().toString()' in stead.

Try EditText.getText().toString()

Take a moment to read the java API: http://download.oracle.com/javase/6/docs/api/java/lang/Object.html#toString%28%29

toString

public String toString() Returns a string representation of the object.

In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns: a string representation of the object.
