EditText maxLines not working - user can still input more lines than set

Question

<EditText
    android:id="@+id/edit_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="text"
    android:maxLines="1" 
/>

You just need to make sure you have the attribute "inputType" set. It doesn't work without this line.

android:inputType="text"

The attribute maxLines corresponds to the maximum height of the EditText, it controls the outer boundaries and not inner text lines.

This does not solve the general issue of limiting to n lines. If you want to limit your EditText to take just 1 line of text, this can be very easy.
You can set this in the xml file.

android:singleLine="true"

or programmatically

editText.setSingleLine(true);

@Cedekasem you are right, there isn't a built in "row limiter". But I did built one my self, so if anyone is interested the code is below. Cheers.

et.setOnKeyListener(new View.OnKeyListener() {

        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            // 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 >= 7) {

                    // 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;
        }
});
