[android-developers] Re: TextView vs Button

Well, a look at the source code reveals that Seshu has a point. There is virtually no difference between a Button and a TextView:

public class Button extends TextView {
    public Button(Context context) {
        this(context, null);
    }

    public Button(Context context, AttributeSet attrs) {
        this(context, attrs, com.android.internal.R.attr.buttonStyle);
    }

    public Button(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
}

you'll answer your question by yourself when you see the source code
of Button.java, just use good, old uncle Google

Never mind the source. You shouldn't have to read source to figure out how to use an API.

From the Javadocs: 

http://developer.android.com/reference/android/widget/Button.html

"Represents a push-button widget. Push-buttons can be pressed, or clicked, by the user to perform an action."

"... instead of applying an OnClickListener to the button in your activity, you can assign a method to your button in the XML layout, using the android:onClick attribute."

http://developer.android.com/reference/android/widget/TextView.html

"Displays text to the user and optionally allows them to edit it. "

Seems like points to differentiate them are already revealed.
