Android material design: remove hint animation

Question

I am building an app that has some AutoCompleteTextView, using amterial design AppCompat. I need to remove the hint animation that this component has, when you tap on the field and the hint goes up, in a smooth animation. Is there any way to remove this animation?

My layout:

<!-- Login progress -->
<ProgressBar android:id="@+id/login_progress" style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:layout_marginBottom="8dp" android:visibility="gone" />

<LinearLayout android:id="@+id/login_form"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

    <LinearLayout android:id="@+id/email_login_form" android:layout_width="match_parent"
        android:layout_height="match_parent" android:orientation="vertical">

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

            <AutoCompleteTextView android:id="@+id/email" android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/prompt_email"
                android:inputType="textEmailAddress"
                android:maxLines="1"
                android:singleLine="true"
                android:theme="@style/AutoCompleteTextViewListasVipHolo" />

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

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

            <EditText android:id="@+id/password" android:layout_width="match_parent"
                android:layout_height="wrap_content" android:hint="@string/prompt_password"
                android:imeActionId="@+id/login"
                android:imeActionLabel="@string/action_sign_in_short"
                android:imeOptions="actionUnspecified" android:inputType="textPassword"
                android:maxLines="1" android:singleLine="true" />

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

        <Button android:id="@+id/email_sign_in_button"
            style="?android:textAppearanceSmall"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:text="@string/action_sign_in"
            android:textStyle="bold" />

        <Button android:id="@+id/register_button"
            style="?android:textAppearanceSmall"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:text="@string/action_register"
            android:textStyle="bold" />

    </LinearLayout>
</LinearLayout>

I don´t want to lose the auto complete feature.

Answer 1

If you want to remove the floating label, then remove the TextInputLayout wrapping around your AutoCompleteTextView. This will remove the floating label feature.

If you want the floating label, but disable the animation, then with the support design library v23 you can use textInputLayout.setHintAnimationEnabled(false); in your code

or app:hintAnimationEnabled="true" as a parameter to the TextInputLayout in XML.

Answer 2

It can be done programmatically very easily by doing the steps below.

1. Set textInputLayout's hint to null

textInputLayout.setHint(null);

2. Set TextInputEditText's hint to your hint text

EditText editText = textInputLayout.getEditText();
editText.setHint("your hint text");
