Android EditText设置边框

效果图：

快速开始

1. 在res/drawable目录下新建样式文件 edit_background.xml。

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>
        <shape
            android:shape="rectangle">
            <solid android:color="#efefef"/>
            <corners android:radius="5dp"/>
            <stroke
                android:width="1dp"
                android:color="#505050"/>
        </shape>
    </item>

2.布局文件中使用边框效果，/res/layout/activity_edit_text.xml。

android:background="@drawable/edit_background"

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".EditTextActivity">

    <TextView
        android:id="@+id/name_label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="账号："
        android:textSize="18sp"
        android:textColor="#353535"
        android:layout_marginTop="60dp"
        android:layout_marginStart="60dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"/>

    <EditText
        android:id="@+id/edit_name"
        android:layout_width="200dp"
        android:layout_height="40dp"
        android:hint="请输入账号"
        android:gravity="center"
        android:inputType="number"
        android:background="@drawable/edit_background"
        android:layout_marginStart="10dp"
        app:layout_constraintTop_toTopOf="@id/name_label"
        app:layout_constraintBottom_toBottomOf="@id/name_label"
        app:layout_constraintLeft_toRightOf="@id/name_label"/>
  

</android.support.constraint.ConstraintLayout>
