Android get view ID based on it's tag

Is there any way to get the ID as in, findViewById(R.id.tableLayout), based on it's XML tag?

For example the Java equivalent of something along these lines: GET $id OF view WHERE 'tag' IS n

Sorry that looks more like SQL, but I thought it would make my question clearer.

I want to be able to find a view based on it's tag and then convert it to a button using something like this.

Button b = (Button) findViewById(android.R.id.button1);

You could just use View#findViewWithTag("someTag") to reference the view then get the id from the view.

View view = findViewWithTag("someTag");
int id = view.getId();

Same thing for a button

Button b = (Button) findViewWithTag("someTag");
int id = b.getId();

references: http://developer.android.com/reference/android/view/View.html#findViewWithTag(java.lang.Object) http://developer.android.com/reference/android/view/View.html#getId()

Edit: If your in an activity (inside onCreate) you could get do this

// create the Activity's view
View root = LayoutInflater.from(this).inflate(R.layout.myLayout, null);
// set the view
setContentView(root);
// find another view by the tag of the root view
Button b = (Button) root.findViewWithTag("someTag");
