Android 如何在 EditText 中使用 TextInputLayout

How to use TextInputLayout with EditText in Android

在我的应用程序中我想使用 TextInputLayout,为此我写了下面的代码。
但是运行申请后,Edit Text!
不显示笔划 只显示空 Edit text!
我的结果图片:

我的代码:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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=".ui.login.send_phone.SendPhonePage">

    <ImageView
        android:id="@+id/sendPhone_logo"
        android:layout_width="@dimen/_150mdp"
        android:layout_height="@dimen/_150mdp"
        android:layout_marginTop="@dimen/_30mdp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:src="@mipmap/ic_launcher_round" />

    <!--Phone number-->
    <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/signInFrag_phoneInpLay"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="@dimen/_15mdp"
        android:layout_marginLeft="@dimen/_15mdp"
        android:layout_marginEnd="@dimen/_15mdp"
        android:layout_marginRight="@dimen/_15mdp"
        app:boxStrokeColor="@color/colorAccent"
        android:layout_marginTop="@dimen/_30mdp"
        app:boxStrokeWidth="@dimen/_1mdp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/sendPhone_logo">

        <EditText
            android:id="@+id/signInFrag_phoneEdt"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:gravity="left|center_vertical"
            android:hint="@string/insertYourPhoneNumber"
            android:inputType="phone"
            android:maxLength="11"
            android:maxLines="1"
            android:paddingLeft="@dimen/_10mdp"
            android:paddingRight="@dimen/_10mdp"
            android:singleLine="true"
            android:textColorHint="@color/colorLightGray"
            android:textSize="@dimen/_10mdp"
            app:drawableRightCompat="@drawable/ic_outline_phone" />

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

</androidx.constraintlayout.widget.ConstraintLayout>

我使用了这种依赖关系:implementation 'com.google.android.material:material:1.2.1' 这种风格 <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

我该如何解决?

使用 TextInputEditText 代替 EditText 并删除 android:background="@android:color/transparent"
