Android 应用程序崩溃'；单击编辑文本后单击

我的应用程序在单击EditText进行键入时崩溃。这发生在Kotlin项目中。我找到了崩溃的原因，即当我声明一个默认值为-1的Int-var userId时。例如：

var userId:Int=-1

在包含EditText的活动中，然后在单击EditText时应用程序开始崩溃。如果更改var名称、数据类型或默认值，则不会发生崩溃

活动：

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    var userId: Int = -1
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }
} 

布局XML:

<?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=".MainActivity">

    <EditText
        app:layout_constraintTop_toTopOf="parent"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</androidx.constraintlayout.widget.ConstraintLayout>

我已经更改了变量名以修复崩溃

解决方案：

var userId:Long=-1
