android - 如何用 EditText 完全填充 TextInputLayout？

Question

我有 EditText 在TextInputLayout. 我想要实现的是EditText完全TextInputLayout摆脱编辑字段顶部的空白区域。

这是布局：

 <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/login_edit_style"
        android:hint=" "> <!--android:hint=" "> if (TextUtils.isEmpty(mHint)) evaluates to false, and the EditText retains its hint.-->


        <EditText
            android:id="@+id/login"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@android:color/transparent"
            android:drawableLeft="@drawable/ic_person"
            android:fontFamily="@font/montserrat"
            android:hint="Email"
            android:inputType="textEmailAddress"
            android:lineSpacingMultiplier="1.17"
            android:paddingLeft="@dimen/field_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:textColor="#4A4A4A"
            android:textColorHint="@color/colorPrimaryDark"
            android:textCursorDrawable="@drawable/cursor_colour"
            android:textSize="12sp" />

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

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="8dp"
        android:layout_marginTop="8dp"
        android:background="@drawable/login_edit_style"
        android:hint=" "> <!--if (TextUtils.isEmpty(mHint)) evaluates to false, and the EditText retains its hint.-->

        <EditText
            android:id="@+id/password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:drawableLeft="@drawable/ic_locker"
            android:drawableRight="@drawable/ic_show_pass"
            android:ems="10"
            android:hint="Password"
            android:inputType="textPassword"
            android:lineSpacingMultiplier="1.17"
            android:paddingLeft="@dimen/field_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:textColor="#4A4A4A"
            android:textColorHint="@color/colorPrimaryDark"
            android:textCursorDrawable="@drawable/cursor_colour"
            android:textSize="12sp" />

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

顶部的空间是用户关注 EditText 时出现的浮动标签，如下所示：

如果您不想要那个浮动标签，请切换到仅使用EditText. 此外，如果您正在使用TextInputLayout，则应该在TextInputEditText其中使用，而不仅仅是EditText.
