android - 如何创建类似 edittext 布局的 Gmail

Question

需要这样的布局

Answer 1

您必须将样式 style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox" 添加到 TextInputLayout

如果您已经离开 android 支持库并且当前正在使用 Material Design Components .

<com.google.android.material.textfield.TextInputLayout
    android:id="@+id/emailTextInputLayout"
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="@dimen/edit_text_horizontal_margin"
    android:layout_marginEnd="@dimen/edit_text_horizontal_margin"
    android:layout_marginBottom="@dimen/edit_text_vertical_margin"
    android:hint="Username"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <com.google.android.material.textfield.TextInputEditText
        android:id="@+id/emailTextInputEditText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress" />

</com.google.android.material.textfield.TextInputLayout>

如果没有，我建议您阅读我写的关于如何 migrate to Material Design Components 的文章.

旧答案:

例如:

<android.support.design.widget.TextInputLayout
    android:id="@+id/emailTextInputLayout"
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="@dimen/edit_text_horizontal_margin"
    android:layout_marginEnd="@dimen/edit_text_horizontal_margin"
    android:layout_marginBottom="@dimen/edit_text_vertical_margin"
    android:hint="Username"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <android.support.design.widget.TextInputEditText
        android:id="@+id/emailTextInputEditText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress" />

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