您可以将TextWatcher绑定到textView，如下面的代码段所示，并在textView中监听文本更改。

...
txtView = (TextView)findViewById(R.id.txt);
txtView.addTextChangedListener(new TextWatcher() {

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

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
        }

        @Override
        public void afterTextChanged(Editable s) {
            if(txtView.getLineCount() > 1){
                txtView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 14);
            }
        }
});

使用spannable

String s= "Hello Everyone next line";
 SpannableString ss1=  new SpannableString(s);
 ss1.setSpan(new RelativeSizeSpan(2f), 0,13, 0); // set size of Hello Everyone
 ss1.setSpan(new RelativeSizeSpan(f), 14,23, 0);// set size of Next line
 TextView tv= (TextView) findViewById(R.id.textview);
 tv.setText(ss1);
