Setting attribute of child element of included layout

No, there is no way to pass parameters to the included layout other than the layout params using the <include> directive.

You can inflate the layout programatically and add them to your view. Add an id to the container in your main layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" />

Then in your Activity:

ViewGroup container = (ViewGroup)findViewById(R.id.container);
for (int i = 0; i < 6; i++) {
    View myLayout = getLayoutInflater.inflate(R.layout.mylayout, null);
    TextView tv = myLayout.findViewById(R.id.textView);
    tv.setText("my layout " + i);
    container.addView(myLayout); // you can pass extra layout params here too
}
