Try this recursive function:
public void disableAllViews(View v){
v.setEnabled(false);
if(v instanceof ViewGroup){
for (int i = 0; i < ((ViewGroup)v).getChildCount(); i++) {
View view = ((ViewGroup)v).getChildAt(i);
disableAllViews(view);
}
}
}
And call it as
LinearLayout myLayout
= (LinearLayout)v.findViewById(R.id.addEditSection1);
disableAllViews(myLayout);
