android how to make text in an edittext exactly fixed lines

I want to allow use to enter just 5 lines, I tried this

<EditText
    android:layout_below="@+id/tv_signup_descriptionError"
    android:id="@+id/et_signup_description"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dip"
    android:hint="@string/et_hint_enterDescription"
    android:singleLine="false"
    android:lines="5"
    android:gravity="top"
    android:scrollHorizontally="false"
    android:inputType="textMultiLine" 
    android:maxLines="5"/>

but still I can press Enter after the fifth line

@Swayam you are right, But this solution has improved :

1- better performance

2- in your solution if you entered 7 lines (your max input lines) then pressed enter in Top lines the last line will be delete, But in this solution "enter" key has ignored.

 mEditText.setOnKeyListener(new View.OnKeyListener() {

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

                if (keyCode == KeyEvent.KEYCODE_ENTER  && event.getAction() == KeyEvent.ACTION_DOWN) {

                    if ( ((EditText)v).getLineCount() >= 7 )
                        return true;
                    }

                return false;
            }
     });
