TextInputLayout作为文本区域 - Android

Question

我正试图在我的应用程序中创建这样的东西(取自谷歌文档):

现在,我尝试创建一个TextInputLayout元素并尝试在其周围放置边框,但我无法让它看起来像我发布的图像.

这是我的代码TextInputLayout:

<android.support.design.widget.TextInputLayout
        android:id="@+id/shipper_layout"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginTop="8dp"
        android:background="@drawable/text_layout_stroke_normal"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginStart="8dp"
        android:layout_marginEnd="8dp">

        <EditText
            android:id="@+id/shipper_field"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:padding="15dp"
            android:background="@null"
            android:gravity="top"
            android:hint="@string/shipper_field"
            android:inputType="textMultiLine"
            android:overScrollMode="always"
            android:scrollbarStyle="insideInset"
            android:scrollbars="vertical" />
    </android.support.design.widget.TextInputLayout>

以下是它的外观:(关注之前)

您可以看到边框未按预期更改,并且提示只是最小化

试试这段代码:

在Xml中:

 <android.support.design.widget.TextInputLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/shipper_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <EditText
        android:id="@+id/shipper_field"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:background="@drawable/text_layout_stroke_normal"
        android:gravity="top"
        android:hint="HELLO"
        android:inputType="textMultiLine"
        android:overScrollMode="always"
        android:padding="15dp"
        android:scrollbarStyle="insideInset"
        android:scrollbars="vertical" />
</android.support.design.widget.TextInputLayout>

现在在代码中以programetically方式更改边框和Edittext使用的提示颜色setOnFocusChangeListener

 edittext.setOnFocusChangeListener(new OnFocusChangeListener() {          
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus) {
                GradientDrawable drawable = (GradientDrawable)edittext.getBackground();
                drawable.setStroke(2, Color.RED);
                edittext.setHintTextColor(Color.RED);
            }
        }
    });

尝试这个：

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="8dp"
    android:hint="textArea">

    <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:inputType="textMultiLine"
        android:gravity="top"
        android:lines="4"
        android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>

确保您使用的是最新的材料库：

implementation 'com.google.android.material:material:1.2.1'

尝试这个

在drawable文件夹中创建一个名为custom_borders.xml的xml文件并粘贴以下代码

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

    <stroke android:color="#ff0000" android:width="2dp"></stroke>
    <corners android:radius="5dp"></corners>

</shape>

并将其应用到你的TextInputLayout像这样

android:background="@drawable/custom_borders"
