Android 如何创建类似Gmail的edittext布局

需要这样的布局吗

---

您必须将样式

style=“@style/Widget.MaterialComponents.TextInputLayout.OutlineBox”

添加到

TextInputLayout

如果您已经离开android支持库并正在使用

如果没有，我建议你读一下我写的关于如何做的文章

旧答案：

<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>

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>

支持新库

implementation 'com.google.android.material:material:1.1.0'

在androidx中使用com.google.android.material.textfield.TextInputLayout而不是android.support.design.widget.TextInputLayout。类似地，使用com.google.android.material.textfield.textinputtext代替android.support.design.widget.textinputtext。
