Intro

This is a python script which scans android xml layout file and generate java code that create a static ContentView class.

Concept

Seeing views inside of activity as member variables makes me uncomfortable. They are members of "ContentView" of the activity, or Window. That's why I use this little pattern for almost all my activities, that is, creating a ContentView static class for every layout. much like famous "ViewHolder" pattern.

Example

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        />
</RelativeLayout>

public class MainActivity {

    ContentView content;
    
    @Override protected void onCreate(Bundle savedInstanceState) {
        content = ContentView.attachTo(getWindow());
    }

    private static class ContentView {
        public static final int LAYOUT_ID = R.layout.activity_main; 

        public View root;
        public TextView tv;

        public ContentView(View v) {
            this.root = v;
            this.tv = (TextView) root.findViewById(R.id.tv);
        }

        public static ContentView attachTo(Window window) {
            View v = LayoutInflater.from(window.getContext()).inflate(LAYOUT_ID, null);
            window.setContentView(v);
            return new ContentView(v);
        }
    }
}

Further

If your layout is very complex, you can create static class inside the ContentView class to manage the complexity. Thus you can access your views like content.layoutSettings.layoutMobile.cb, autocomplete of IDE will provide information about what are the views inside this layout.
