编辑文本不显示值

我在数据库中有一个double类型的列,现在,我获取该值并尝试将其指定为数字签名-数字十进制编辑文本,然后使用kotlin to String方法将该值转换为字符串。但是编辑文本中没有显示任何内容。当我使用println方法时,值出现在logcat中。我不知道该怎么办。我有其他输入,显示文本没有问题,但这种类型的编辑文本不适合我。

这是我用来启动活动的代码:

        val recordEditButtonListener = View.OnClickListener {
            val intent = Intent(context, AddEditRecordActivity::class.java)

            intent.putExtra(RECORD_ID, currentRecord.id)
            intent.putExtra(RECORD_CATEGORY, currentRecord.category)
            intent.putExtra(RECORD_AMOUNT, currentRecord.amount)
            intent.putExtra(RECORD_DATE, currentRecord.date)
            intent.putExtra(RECORD_DESCRIPTION, currentRecord.description)

            activity.startActivityForResult(intent, EDIT_RECORD_REQUEST)
        }

这是活动本身:

val amountText = intent.getDoubleExtra(RECORD_AMOUNT, 1.0).toString()
amount_input.setText(amountText)

这是记录表结构:

@Entity(
    foreignKeys = [ForeignKey(
        entity = Account::class,
        parentColumns = arrayOf("id"),
        childColumns = arrayOf("accountId"),
        onDelete = CASCADE,
        onUpdate = NO_ACTION
    )]
)
class Record(
    @PrimaryKey(autoGenerate = true) var id: Int?,
    var amount: Double,
    var category: String,
    var description: String,
    var date: String,
    var recordImage: String,
    var recordImageDescription: String,
    var accountId: Int
)

这是xml:

<EditText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ems="10"
            android:layout_marginTop="16dp"
            app:layout_constraintTop_toBottomOf="@+id/category_spinner"
            android:layout_marginStart="16dp" app:layout_constraintStart_toStartOf="parent"
            android:hint="@string/record_amount_input_text" android:id="@+id/amount_input"
            android:inputType="numberSigned|numberDecimal"/>
    <TextView
            android:text="@string/record_select_date_text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:id="@+id/date_text"
            android:textSize="22sp"
            app:layout_constraintStart_toStartOf="@+id/amount_input"
            android:layout_marginTop="32dp" app:layout_constraintTop_toBottomOf="@+id/amount_input"/>
    <EditText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ems="10"
            android:id="@+id/description_input" android:layout_marginTop="32dp"
            app:layout_constraintTop_toBottomOf="@+id/date_text"
            app:layout_constraintStart_toStartOf="@+id/date_text" android:inputType="text"
            android:hint="@string/record_description_input_text"/>
