是否可以在widget.TextInputLayout中管理工具提示

Question

作为Edittext，它不是组小部件中唯一的一个。使用TextInputLayout提示不起作用。告诉我有什么方法可以召唤帮助吗？

这是我的布局：

<android.support.design.widget.TextInputLayout
    android:id="@+id/til_account"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="10dp"
    android:layout_weight="1"
    android:textColorHint="@color/colorTextHint">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <EditText
            android:id="@+id/et_account_tint"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="@color/colorTextHint"
            android:maxLines="1"
            android:theme="@style/EditText"
            android:textSize="16sp" />
        <EditText
            android:id="@+id/et_account"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentStart="true"
            android:layout_alignParentTop="true"
            android:drawableRight="@mipmap/ic_selectcontact"
            android:hint="@string/enter_phone_number_contact_name"
            android:inputType="text"
            android:maxLines="1"
            android:textColorHint="@color/colorTextHint"
            android:textSize="16sp"
            android:theme="@style/EditText" />
        <TextView
            android:id="@+id/et_account_button"
            android:layout_width="70dp"
            android:layout_height="35dp"
            android:layout_alignParentEnd="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentTop="true"
            android:background="@android:color/transparent"
            android:onClick="@{presenter::onClick}"
            android:textSize="16sp"
            tools:ignore="LabelFor" />
    </RelativeLayout>
</android.support.design.widget.TextInputLayout>
