How to check if a particular view is currently focussed in Android

In my android app I need to check whether a particular view is focussed. Now I found the getCurrentFocus() function in Activity class but this returns a View Object.

How can I compare and check whether this returned View is same as the one in question. I mean there is no getName() function here. So after getting the View object, how can I compare to check which View class is this ?

The View.isFocused() method tells whether the view in question is focused or not.

if (myView.isFocused()) {
    // your code
}

If you still want to use the getCurrentFocus() method, you can simply check:

View focusView = getCurrentFocus();
if (myView == focusView) {
    // your code
}

Or else, you can compare your views by id.

View focusView = getCurrentFocus();
if (focusView != null && myView.getId() == focusView.getId()) {
    // your code
}

No need for getName(). Just use the == operator. See:

View myView = findViewById(...);

if (activitygetCurrentFocus() == myView)
    // ha focus

}

Another option, one I usually prefer, is to set a focus listener for the views you are interested in monitoring:

myView.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
          if (hasFocus) {
               // got focus logic
          }
    }
});

You could use the getId() method I guess?

e.g. 

getCurrentFocus() == R.id.myView;
