ListView onItemClick which implements Activity is not working

I have a listview extends Activity and use custom adapter because I want icon and text on the listview.

String[] options = res.getStringArray(R.array.menu_title);
    TypedArray icons = res.obtainTypedArray(R.array.menu_icon);
    ImageAndTextAdapter iadapter = new ImageAndTextAdapter(ctx, R.layout.row, options, icons);
    MenuList.setAdapter(iadapter);

Then I use the setOnItemClickListener to make the listview clickable but fail.

MenuList.setOnItemClickListener(new ListView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
            Intent myIntent = new Intent(Menu.this, Revision.class);    
            Menu.this.startActivity(myIntent);
            }
    });

Here is the logcat:

It appears that your problem might actually be in Revision.class. Without seeing that code, i cant say for sure, but the part of the Logcat that points to that would be:

 java.lang.ClassCastException: android.widget.LinearLayout
