I searched everywhere but I cannot find a solution for this simple question: I'm using a predefined layout R.layout.simple_list_item_1
but I cannot find the way to modify the text color of the TextViews inside it.
If you don't want to use your own XML layout, you can get the TextView from that layout and set the color on that. The ID of the TextView in R.layout.simple_list_item_1
is android.R.id.text1
(see the source for that layout).
TextView tv = (TextView) findViewById(android.R.id.text1);
tv.setTextColor(getColor(R.color.new_text_color);
