Answer 1

EXAMPLE USAGE:

Button[] buttons = initializeButtons(3);
buttons[1].setText("I am button1");
buttons[2].setText("I am button2");
buttons[3].setText("I am button3");

FUNCTION:

public Button[] initializeButtons(int x) {
    Resources res = getResources();
    Button[] buttons = new Button[x];
    for (int i = 0; i < x; i++) {
        String b = "button" + i;
        buttons[i] = (Button) findViewById(res.getIdentifier(b, "id", getPackageName()));
    } return buttons;//to prevent array out of bounds exception start from 0
}

NOTE: Make sure in your layout the button id is button1, button2, button3, .. .. etc'
