Look here: How to adjust text font size to fit textview

Overview:

Create a CustomTextView
Extend TextView
override method onMeasure()
Do your calculations on the text width [Hint: get width by calling this.getWidth()]
Set calculated text size [Hint: use this.setTextSize()]

You can check the content of your EditText should ellipsize by the method provided in TextUtils, the following code is a simple example.

    EditText editText = new EditText(this);
    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            String ellipseString = TextUtils.ellipsize(s, editText.getPaint(), editText.getWidth(), TextUtils.TruncateAt.END, false, new TextUtils.EllipsizeCallback() {
                @Override
                public void ellipsized(int start, int end) {
                }
            }).toString();
            if (ellipseString.contains("\u2026")) {
                Log.d(TAG, "ellipse");
            }
        }
    });
