Answer 1

Lets say you have a custom view named InputView, which is not a TextView (lets say its a RelativeLayout).

In your attrs.xml:

In an xml layout where you want to include InputView:

Inside your custom class you can extract attributes as usual:

    ...

    private String title;
    private int inputType;
    private int imeOptions;

    ...
    TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.InputView);

    int n = a.getIndexCount();
    for (int i = 0; i < n; i++) {
        int attr = a.getIndex(i);
        switch (attr) {
        case R.styleable.InputView_title:
            title = a.getString(attr);
            break;
        //note that you are accessing standart attributes using your attrs identifier
        case R.styleable.InputView_android_inputType:
            inputType = a.getInt(attr, EditorInfo.TYPE_TEXT_VARIATION_NORMAL);
            break;
        case R.styleable.InputView_android_imeOptions:
            imeOptions = a.getInt(attr, 0);
            break;
        default:
            Log.d("TAG", "Unknown attribute for " + getClass().toString() + ": " + attr);
            break;
        }
    }

    a.recycle();
    ...
