How to access Button inside "include" layout

Solution 1:

The id you have with the include tag is assigned to the root View of the included layout. First get a reference to that View using findViewByid. Then you can call findViewById on that specific View to get a reference to a View inside the layout. So:

View myLayout = findViewById( R.id.cell1 ); // root View id from that link
View myView = myLayout.findViewById( R.id.someinnerview ); // id of a view contained in the included file

Solution 2:

All you need is the id of the parent view:

In this example, the LinearLayout is the parent of the TextView I want from the included View.

I can now do this:

    View view = findViewById(R.id.include_title_layout);
    TextView titleTV = (TextView) view.findViewById(R.id.newsTitleTextView);
    titleTV.setText("Whatever");

Solution 3:

You do know the id of the include. You can get that complete element, and then get one of its children starting from there.

Solution 4:

Actually include tags include all the elements in your root layout. So you can always access them using findViewById on your Activity.

Suppose you have a alayout.xml in which there is a include layout. Now in one of your activity A,inside onCreate you declared setContentView(R.layout.alayout) Now inside your include layout you might have a button with id myBtn. You can access that inside onCreate in the same way you could access it if it were in main layout: findViewById(R.id.myBtn)
