Question: How to access outer class from inside the OnClickListener

Answer: Replace this in your code with MyActivity.this where MyActivity is the class name of your Activity subclass.

Explanation: You are creating an anonymous inner class when you use this part of your code: new OnClickListener() { Anonymous inner classes have a reference to the instance of the class they are created in. It looks like you are creating it inside an Activity subclass because findViewById is an Activity method. Activity's are a Context, so all you need to do is use the reference to it that you have automatically.

findViewById(R.id.Button01).setOnClickListener(new OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                List<ActivityInfo> activities = this.getPackageManager().queryIntentActivities(mainApps, 0);
            }
        });

                @Override
                public void onClick(View v) {
                    mMyFilterView.setLUTBitmap(MyValues.filterID[index]);
                }
            });
        }
