Disable all elements in a layout - Android

In my Android app there is a requirement that a number of UI elements should be disabled until a button is clicked. Can I disable all the UI elements in a layout by referring the layout without disable them one by one?

Use following attribute in your xml layout (as a example textView):

android:visibility="gone"

In button click event:

myText.setVisible(myText.VISIBLE)

You can either use them one by one or you can put all invisible content in a single layout and hide the layout. Then once you want to show them, just VISIBLE the layout, then all will display.

You could disable all views recursively like this. Just pass the layout as view to the method:

private void enableViews(View v, boolean enabled) {
    if (v instanceof ViewGroup) {
        ViewGroup vg = (ViewGroup) v;
        for (int i = 0;i<vg.getChildCount();i++) {
            enableViews(vg.getChildAt(i), enabled);
        }
    } 
    v.setEnabled(enabled);
}

Just run enableViews(view, false) to disable, or enableViews(view, true) to enable again.
