How can I get the View received by OnClick without calling it?

Question

The code below works perfect:

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button button = (Button) this.findViewById(R.id.btn1);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            method.show(v);
        }
    });
}

However, I need to get View without using onClick

The code below does not work

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button button = (Button) this.findViewById(R.id.btn1);

    method.show(button);
}

How can I get the same View as passed to button.onClick?

Thank you very much.

Your code looks valid. What do you mean by "the code below does not work". Nothing happens? It throws an exception? Or what? — Brayden, May 30 '12 at 20:13
what you want we can't understand u? be more specific!! public void onClick(View v) the argument here is the view that was clicked — K_Anas, May 30 '12 at 20:15
@Brayden I get the following error: android.view.WindowManager $ BadTokenException: Unable to add window - token null is not valid; WindowManager not recognized button as a View — Cris Marinho, May 30 '12 at 20:22
What line do you get that at? You should post the full stack trace. — Brayden, May 30 '12 at 20:24
The method opens a popup on the screen The error occurs on this line: PopupWindow.showAtLocation (parentView, Gravity.NO_GRAVITY, xpos, ypos); View parentView where is the button. method but only works with onClick (View v). — Cris Marinho, May 30 '12 at 20:39

I'm afraid you can't show a PopupWindow from onCreate().

Perfect. was just that. Runnable in the post, the button was given the attributes of screen position required. Thank you – Cris Marinho May 31 '12 at 13:37
