android how to limit the lines on edittext

Question

I want to have 5 lines in an edittext, so the user can press Enter just 4 times, I tried like this but still can't work

myEtidtext.setOnKeyListener(new OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
    // TODO Auto-generated method stub
    // if enter is pressed start calculating
    if (keyCode == KeyEvent.KEYCODE_ENTER && event.getAction() == KeyEvent.ACTION_UP) {
        // get EditText text
        String text = ((EditText) v).getText().toString();
        // find how many rows it cointains
        int editTextRowCount = text.split("\\n").length;
        // user has input more than limited - lets do something
        // about that
        if (editTextRowCount >= 5) {
            // find the last break
            int lastBreakIndex = text.lastIndexOf("\n");
            // compose new text
            String newText = text.substring(0, lastBreakIndex);
            // add new text - delete old one and append new one
            // (append because I want the cursor to be at the end)
            ((EditText) v).setText("");
            ((EditText) v).append(newText);
        }
    }
    return false;
}
});

Have tried android:maxlines=4 in your xml or setMaxlines(int) method in your java or your refer this link http://stackoverflow.com/questions/7092961/edittext-maxlines-not-working-user-can-still-input-more-lines-than-set — Pragnani, Feb 03 '13 at 13:08

You can set the number of chars in that EditText to (for example 300 chars)

et_description.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                // TODO Auto-generated method stub
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub

            }

            @Override
            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub
                if (s.toString().length() > 300) {
                    et_description.setText(s.toString().subSequence(0, 300));
                }
            }
        });
