Question

I want to cast multiple XML layouts as views. Because of a change request I need to use a ViewSwitcher. So I have to cast the XML layout to Views before setContentView.

I always get a NullPointerException. I tried:

view = (View) findViewById(R.id.viewgroup_id);

view = (RelativeLayout) findViewById(R.id.viewgroup_id);

view = (View) findViewById(R.layout.xml_layout);

view = (View) getResources().getLayout(R.layout.xml_layout);

Try using LayoutInflater. Use this code inside your activity code-

   LayoutInflater inflater = getLayoutInflater();
   View view = inflater.inflate(R.layout.your_layout, null);
