'static' method modifier not working with Android widgets

Question

In my Android Application, I want to change this method to static, however when I add 'static' to the method signature, my IDE tells me that a non-static context cannot be referenced from a static context (on the findViewByID(R.id.listView).

public void populateListView(ArrayList<Income> incomeArray) {
    ArrayList<Income> array = incomeArray;
    ArrayAdapter<Income> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, array);
    ListView listView = (ListView) findViewById(R.id.listView);
    listView.setAdapter(adapter);

How could I make this method static?

`findViewByID` is an instance method - so it needs to be invoked on an instance of the relevant class. — Jon Skeet, Apr 24 '15 at 15:46
Those are not static. Look @ http://androidxref.com/5.1.0_r1/xref/frameworks/base/core/java/android/app/Activity.java — Raghunandan, Apr 24 '15 at 15:46

make them global and Initialize your values out of your function or passing them as an argument, you are using this.findViewById(R.id.listView) which is not a static function.
