Android TextInputField Inflator Error

Had a crash while trying to use the new

TextInputField
for Android and wanted to share my solution.

Trying the new TextInputField in the android appcompat library was crashing my app. Here was my layout xml.

<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

<EditText
android:id="@+id/email"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="e-mail"
android:inputType="textEmailAddress"
android:singleLine="true"/>

</android.support.design.widget.TextInputLayout>


The error I got:

android.view.InflateException: Binary XML file line #20: Error inflating class android.support.design.widget.TextInputLayout.


SOLUTION:
Add the
hintTextAppearance
attribute to your
TextInputLayout
, so the lead tag looks like this:

<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintTextAppearance="@android:style/TextAppearance.Medium">

Answer

Make sure you have the following dependencies in your gradle file:

compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:design:22.2.0'

Working example:

<android.support.design.widget.TextInputLayout
    android:id="@+id/txtEmail_InpLyt"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
        android:ems="10"
        android:id="@+id/txtEmail"
        android:hint="Email Address"
        android:singleLine="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"/>
</android.support.design.widget.TextInputLayout>

(Setting hintTextAppearance is not necessary.)

Update:

If you experience issues with the hint text not appearing in newer versions of Android (Marshmallow / Nougat), update library to version 22.2.1 (see TextInputLayout not showing EditText hint before user focus on it).

compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:design:22.2.1'
