FindView class to remove the ugly casting of Android Views

README.md

FindView helper class

---

What is it?

This is a simple helper class to casting the Views of your layout file in your Activity or Fragment.

---

Why?

Normally you get your layout Views like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splashscreen);

    TextView tv = (TextView) findViewById(R.id.textview)
}

You need to casting all the views in the "right" view, when needed. That is ugly!

---

How to use?

With theses static helper class you can directly get your View you want.

For example

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splashscreen);

    TextView tv = FindView.getView(this, R.id.textview)
}

So put the FindView class in your Utils package and use it like a pro ;)
