How to Fix: EditText maxLines not working - user can still input more lines than set
Limit EditText input to fixed number of lines by using android:inputType="textOneLine" and handling Enter key press.
📋 Table of Contents
The issue you're facing is due to the fact that the `android:lines` attribute is not sufficient to limit the number of lines in an EditText, as it only sets a minimum height for the view. To fix this, you need to use the `inputType` and `imeOptions` attributes along with the `android:maxLines` attribute.
🔍 Why This Happens
- Android EditText does not enforce the maximum number of lines when using the default `inputType` and `imeOptions`. To limit the input, you need to specify a custom input type.
✅ Best Solutions to Fix It
Method 1: Using Custom Input Type
- Step 1: Set the `inputType` attribute to `TextAppearance.AppCompat.LineSpacingAddictions` and specify a maximum number of lines using `android:maxLines`.
Method 2: Using IME Options
- Step 1: Set the `imeOptions` attribute to `InputType.TYPE_TEXT_FLAG_ONE_LINE`. This will limit the input to a single line.
✨ Wrapping Up
By using one of these methods, you can effectively limit the number of lines in an EditText and prevent users from inputting more than a specified amount.
