You indicated you wanted to be able to find a View by some String name.
Since Views are not stored anywhere by a String name, you will have to
make this mapping yourself. The standard Java interface for mapping one
value to another is java.util.Map, and the typical implementation of
that is java.util.HashMap.
Map<String, Integer> widgetsByName=new HashMap<String, Integer>();
widgetsByName.put("why", R.id.btn1);
widgetsByName.put("you", R.id.btn2);
widgetsByName.put("want", R.id.btn4);
widgetsByName.put("this", R.id.btn5);
widgetsByName.put("is", R.id.btn5);
widgetsByName.put("beyond", R.id.btn6);
widgetsByName.put("my", R.id.btn7);
widgetsByName.put("understanding", R.id.btn8);
(where you would use your own String names and widget IDs)
Then, sometime later, given a String name, you could:
Button btn=(Button)findViewById(widgetsByName(name));

In Java, arrays are indexed by integers, not Strings.
