Keep Textinputlayout hint always top

问题

Would be possible have my hint text always top, as if it were focusable?

I tried this:

 <android.support.design.widget.TextInputLayout
            android:id="@+id/etSurnameInput"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/llNameImage"
            android:hint="My Hint Text"
            app:hintEnabled="true"
            app:hintAnimationEnabled="false"
            android:textColorHint="@color/gray_title">

Here's a hack - programmatically add a space in the text if it's empty. However, you would then have to remove the space if it's focused, else the user will start typing with a leading whitespace. Another option is to always trim the text typed by user.

My final solution back then was to actually just set hintEnabled="false" & use a TextView on top.

You can set android:minLines="2" to the TextInputEditText or greater than 2. Also keep android:gravity="top"

<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="100dp"
        android:gravity="top"
        android:hint="Username"
        android:minLines="2" />
