How to set an EditText's initial height while allowing it to expand when overflows

I am currently working on an android app and i'm having some problems with EditText.

I want to create an editText with an empty string starting off with the height equivalent to 1 or more lines and maintaining that height, but allowing it to grow when text starts to overflow beneath the current size.

I tried several things :

  1. If I set the Edittext's size to a certain value, it doesn't grow... the previous lines just go up and become invisible

  2. When I don't set the size and use the default height, then the edittext always starts off with the height of two lines, not 1 line.

How can I fix this?

Anyone else still having issue with this or with TextInputEditText in the material design? It seems like the internal padding for TextInputEditText is automatically adjusted even when setting explicit android:textSize android:minLines and android:minHeight. You still have to explicitly set the padding.

<com.google.android.material.textfield.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
>
    <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="16sp"
        android:inputType="textMultiLine"
        android:minLines="1"
        android:minHeight="35dp"

        android:paddingHorizontal="16dp"
        android:paddingVertical="0dp"/> 

        <!-- /\ Add the two lines above /\ -->

</com.google.android.material.textfield.TextInputLayout>

How about using these option? 

android:maxHeight="100dip"
android:minHeight="40dip"

MaxHeight will force your EditText's height no more than 100dip.

MinHeight will force your EditText's height minimum is 40dip.

Example)

<EditText
    android:id="@+id/somethingEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="56dip"
    android:maxHeight="200dip"
    android:minLines="1" />

This code will force your EditTex's height range to '56dip ~ 200dip'

You can set minimum lines using minLines Property of edittext, also use height as wrap content to make it expandable.

<EditText 
android:width = "match_parent"
android:height= "wrap_content"
android:minLines="1"/>

you can try to use wrap content which should expand with the text

<EditText 
android:width = "match_parent"
android:height= "wrap_content"/>
