Android IME - how to detect entering a View?

I am trying to write a custom IME for the Android OS. However, I cannot figure out how to detect when the user is entering e.g. an EditText.

I have already tried overriding some of the on...() methods of InputMethodService to no avail.

The documentation hasn't been particularly helpful to me he开发者_StackOverflowre, I'm having a hard time understanding the description of the InputMethodService class.

Use TextWatcher to find out when a user is entering text into an EditText. Otherwise, for any other view, you should be able to override the onFocusChanged method.

Just for documentation purposes: I found the answer myself.

When a view is entered, the InputMethodService's onStartInput(EditorInfo attribute, boolean restarting) method is called. If the EditorInfo's InputType is != 0, the view is editable, it seems.
