Answer 1

If you name all of your buttons “button1, button2, button3…” you can do this:

for(int i = 1; i <= buttonCount; i++) {
    int id = getResources().getIdentifier("button" + i, "id", getPackageName() );
    findViewById(id).setOnClickListener(this);
}

Where buttonCount is the amount of buttons you have. This method would be placed in onCreate().

Then for your onClick:

public void onClick(View v) {
    if (v instanceof TextView) {
        CharSequence text = ((TextView) v).getText();
        // Do fun stuff with text
    }
}

Your Activity will need to implement OnClickListener
