    TextView tv1 = (TextView) findViewById(R.id.tv1);
    tv1.setText("abcd\nhello\nworld123\n333333");
    tv1.post(new Runnable() {
        @Override
        public void run() {
            int lineCount    = tv1.getLineCount();
            Toast.makeText(MainActivity.this, "行数为:"+lineCount, Toast.LENGTH_LONG).show();
        }//行数为4
    });
