I\'m trying to add a textView to a frameLayout. The TextView has wrap_content properties, so it grows when the text grows
Try this:
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER);
((FrameLayout) findViewById(R.id.mainLayout)).addView(mEditText, params);
Change Gravity to suit your need.
BTW, the frame layout should use fill_parent for width and height
