Multi-line EditText with Done action button

Question

Use

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);
editText.setRawInputType(InputType.TYPE_CLASS_TEXT);

and in XML:

android:inputType="textMultiLine"

From the android documentation: '"textMultiLine" Normal text keyboard that allow users to input long strings of text that include line breaks (carriage returns).' Therefore the textMultiLine attribute is not appropriate if you want to have the 'Done' button in the keyboard.

A simple way to get a multi-line (in this case 3 lines) input field with the done button is to use EditText with

android:lines="3" 
android:scrollHorizontally="false" 

However, for some reason this only works for me if I do these settings in the code instead of the layout file (in onCreate) by

TextView tv = (TextView)findViewById(R.id.editText);
if (tv != null) {
    tv.setHorizontallyScrolling(false);
    tv.setLines(3);
}

I hope this helps someone, as it took quite a while to figure out. If you find a way to make it work from the manifest, please let us know.

Working Example! Create the below custom EditText class that supports this feature and use the class in the xml file. Working code:

package com.example;

import android.content.Context;
import android.util.AttributeSet;
import android.view.inputmethod.EditorInfo;
import android.view.inputmethod.InputConnection;
import android.widget.EditText;

public class ActionEditText extends EditText
{
   public ActionEditText(Context context)
   {
       super(context);
   }

   public ActionEditText(Context context, AttributeSet attrs)
   {
       super(context, attrs);
   }

   public ActionEditText(Context context, AttributeSet attrs, int defStyle)
   {
       super(context, attrs, defStyle);
   }

   @Override
   public InputConnection onCreateInputConnection(EditorInfo outAttrs)
   {
       InputConnection conn = super.onCreateInputConnection(outAttrs);
       outAttrs.imeOptions &= ~EditorInfo.IME_FLAG_NO_ENTER_ACTION;
       return conn;
   }
}

<com.example.ActionEditText
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:imeOptions="actionDone"
       android:inputType="textAutoCorrect|textCapSentences|textMultiLine" />

To do this in Kotlin (and also optionally apply other configurations like textCapSentences you can use this extension function:

// To use this, do NOT set inputType on the EditText in the layout
fun EditText.setMultiLineCapSentencesAndDoneAction() {
    imeOptions = EditorInfo.IME_ACTION_DONE
    setRawInputType(InputType.TYPE_TEXT_FLAG_CAP_SENTENCES or InputType.TYPE_TEXT_FLAG_MULTI_LINE)
}

Usage:

myEditText.setMultiLineCapSentencesAndDoneAction()
