Android - 减少EditText浮动标签填充/边距？

Question

是否可以将这些浮动标签(电子邮件/密码)放在包装盒内.基本上减少了提示和实际输入之间的空间.

我尝试填充顶部/底部.用于editText的边距顶部/底部.但他们都没有给出我想要的结果.

 <android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="20dp"
    android:id="@+id/emailWrapper"
    app:hintTextAppearance="@style/floatingLabel">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="54dp"
        android:paddingLeft="17dp"
        android:paddingRight="17dp"
        android:id="@+id/txtEmail"
        android:singleLine="true"
        android:inputType="textEmailAddress"
        android:hint="@string/emailPlaceholder"
        android:background="@drawable/btn_empty_stroke" />

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

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:hintTextAppearance="@style/floatingLabel"
    android:id="@+id/passwordWrapper"
    android:layout_below="@+id/emailWrapper">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="54dp"
        android:paddingLeft="17dp"
        android:paddingRight="17dp"
        android:singleLine="true"
        android:inputType="textPassword"
        android:id="@+id/txtPassword"
        android:paddingTop="0dp"
        android:text="HELLO"
        android:hint="@string/passwordPlaceholder"
        android:background="@drawable/btn_empty_stroke" />

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

感谢@Frank N.Stein的评论和减少高度的想法.它成功了.

回答我自己的问题.正如其他人可能会提出这个问题.

所以基本上我必须给TextInputLayout准确的高度并保持EditText高度相同.还要将paddingTop赋予TextInputLayout并将clipToPadding设为false.所以最终的文本框xml就是这样出来的.

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_marginTop="20dp"
    android:layout_height="54dp"
    android:gravity="bottom"
    android:paddingTop="4dp"
    android:clipToPadding="false"  // above 3 lines are important
    android:id="@+id/emailWrapper"
    app:hintTextAppearance="@style/floatingLabel">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="54dp"
        android:paddingLeft="17dp"
        android:paddingRight="17dp"
        android:id="@+id/txtEmail"
        android:singleLine="true"
        android:inputType="textEmailAddress"
        android:hint="@string/emailPlaceholder"
        android:text="a@a.com"
        android:background="@drawable/btn_empty_stroke" />

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