如何在android中制作多行edittext

Question

I try to create an edittext dynamically with LayoutParams.MATCHPARENT for its both width and height. I have tried the following code, but it is still not working.

EditText editor = ....;
LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1);
editor.setLayoutParams(params);
editor.setGravity(Gravity.LEFT | Gravity.TOP);
editor.setBackgroundColor(Color.WHITE);
editor.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI);
editor.setTextColor(Color.BLACK);
//editor.setSingleLine(false);
editor.setFocusableInTouchMode(true);
editor.setInputType(EditorInfo.TYPE_CLASS_TEXT | EditorInfo.TYPE_TEXT_FLAG_MULTI_LINE | EditorInfo.TYPE_TEXT_FLAG_IME_MULTI_LINE);
editor.setMaxLines(Integer.MAX_VALUE);
editor.setHorizontallyScrolling(false);
editor.setTransformationMethod(null);

The code above let me to enter several lines, and an 'ENTER' button is displayed in the keyboard, but as I type on the edittext, the edit text scrolls horizontally if the width is not enough to display the text. Can anybody please help me how to make the edittext multiline?
