Question

當我測試我的應用程序並遇到此錯誤時，我嘗試了 stackoverflow 中提供的許多解決方案但沒有奏效。 我以為是material design的版本問題，我升級到material design的最新版本代碼還是不行。

這是我的應用風格

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar"></style>

設計如下

<?xml version="1.0" encoding="utf-8"?>

請我真的需要你的幫助

您忘記關閉 ScrollView 的 RelativeLayout

<?xml version="1.0" encoding="utf-8"?>
<layout 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">

<RelativeLayout
    android:id="@+id/parent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".user_ui.activities.LoginActivity">

    <com.mbula.animations.flowing_gradient.FlowingGradient
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:transition_drawable="@drawable/trans"
        app:transition_duration="4000" />

    <ImageButton
        android:id="@+id/back"
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_margin="20dp"
        android:background="@drawable/awesome_rounded_background"
        android:contentDescription="@string/todo"
        android:src="@drawable/ic_arrow_back_white_24dp" />

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true">

        <RelativeLayout
            android:layout_width="300dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center">

            <ImageView
                android:id="@+id/profil_image"
                android:layout_width="80dp"
                android:layout_height="80dp"
                android:layout_centerHorizontal="true"
                android:layout_marginBottom="10dp"
                android:contentDescription="@string/todo"
                android:src="@drawable/ic_outline_account_circle_24" />

            <com.google.android.material.textfield.TextInputLayout
                android:id="@+id/username_wrapper"
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:layout_below="@+id/profil_image"
                app:errorTextAppearance="@style/TextAppearance.Masolo.Design.Error"
                app:hintTextAppearance="@style/TextAppearance.Masolo.Design.Hint"
                app:startIconDrawable="@drawable/ic_phone_black_24dp">

                <com.masolo.mbula.widgets.TextInputEditText
                    android:id="@+id/credential"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:autofillHints="@string/t_l_phone_ou_email"
                    android:background="@android:color/transparent"
                    android:hint="@string/t_l_phone"
                    android:inputType="text"
                    android:textSize="14sp" />
            </com.google.android.material.textfield.TextInputLayout>
        </RelativeLayout>
    </ScrollView>
</RelativeLayout>
</layout>

還想建議，如果您使用矢量圖像作為 src，請使用 AppCompatImageView。 這就是我們設置矢量圖像的方式。

            <androidx.appcompat.widget.AppCompatImageView
                android:id="@+id/icon"
                android:layout_width="@dimen/_65dp"
                android:layout_height="@dimen/_65dp"
                android:layout_gravity="center"
                app:srcCompat="@drawable/ic_outline_account_circle_24"
                android:background="?selectableItemBackgroundBorderless" />
