Unable to make EditText multi-line

Question

I am making an Android app for storing notes. I have made my editText behave like textView before button click. Clicking on edit button makes the editText take value. Now problem arises when i save that value and when it is displayed. EditText doesnt come in multi-line as I want but in a single line.

I declared the inputType property of editText as multi-line in xml file but in the code upon initialising the editText i set its inputType property as null in an attempt to make it both null and multi-line but alas! It doesn't happen.

Below is my xml and java code:

This image is when I click edit button. This works just fine, text goes to another line.

This image is when i click the save button. The text goes back to single line instead of multi-line.

Answer 1

Okay so, I knew that the problem arises when I click on the edit button. Clicking the button made the editText single lined automatically even though I had mentioned the InputType as Multi-line in XML very clearly.

What I did to make the editText multi-line after the button click is that I wrote editTextContent.setSingleLine(false); in my java file inside the onClick button code. And that is it. :)
